Фундаментальная математика — теория всего в IT и не только. Теория типов и формализация в Coq

705cbebb225c4076df6db75c00a770ba.png

У нас есть 3 "теории всего" - научная картина мира (все сводится к законам физики), информатика (все сводится к битам) и фундамент математики (все сводится к логике). Именно фундамент математики представляет особый интерес, так как он является фундаментом для двух других фундаментов и имеет глубокий философский смысл. Последние 2 года (2023-2024) я сильно им увлекся и проделал довольно большую работу по углубленному изучению теории типов (Calculus of Constructions), и готов поделиться результатами, а также рассказать о девяти направлениях, где можно применить это на практике. Очень многое получилось лучше, чем я планировал. Изначально перспективы были не очень понятными, и поэтому я не рассказывал друзьям и коллегам про мою работу в этом направлении и называл это "Секретный Проект". Но теперь, когда многое прояснилось и получилось, можно поделиться успехом. Собственно, в этой статье я расскажу вам не только про сам фундамент математики, а еще его связь с ежедневной работой программиста, а также с Computer Science/Data Science и AI/ML. Я вам нарисую большую и красивую картину, на которой все понятно и логически следует из маленького набора правил выведений типов (11 штук) и аксиом теории множеств (9 штук).

У нас есть 3 фундамента математики - теория множеств (удобна для человека), теория типов (удобна для компьютера) и теория категорий (не знаю, зачем она вообще нужна). Они примерно одинаковой мощности и одну можно выразить внутри другой. Особый интерес представляет именно теория типов, т.к. ее довольно легко можно запрограммировать внутри компьютера и использовать как строгий фундамент для других теорий, который не дает совершить ошибку и проверяет каждое ваше действие.

А сейчас я вам расскажу короткую историю теорем-пруверов (пруф-ассистентов) - это такие программы, которые позволяют доказывать математические теоремы и строить на их основе фундамент математики с нуля. В 1973 появился проект Mizar (в Польше) и он был первым успешным теорем-прувером. На данный момент его библиотека - самая большая (52,000 доказанных теорем и 10,000 математических определений).

Разработчики Mizar попробовали создать теорем-прувер полностью на теории множеств (что казалось логичным на тот момент), но в итоге получился огромный архитектурный костыль - им пришлось поддерживать 2 ядра одновременно (теория типов и теория множеств) вместо одного. Это плохо не только для разработки/поддержки системы, но и для освоения\обучения\расширения.

Прошло время и теория типов сформировалась как отдельная дисциплина, хорошо проработанная и сформированная. Исследователям удалось очень чисто (без костылей) выразить математическую логику внутри теории типов, и сделать ее 100% совместимой с тем, как думают математики. Как им удалось до этого догадаться и сделать такой большой прорыв - я не знаю. Так вот, если мы полностью формализуем математическую логику, то аксиоматическая теория множеств очень чисто и легко выводится из нее. Нужно всего лишь аксиоматически задать существование отношения принадлежности к множеству (∈), а также добавить 9 аксиом ZFC (Zermelo–Fraenkel Set Theory), которые по сути постулируют существование двух множеств (пустое и бесконечное) и как с ними работать. А саму формальную систему математической логики (набор правил) называют Натуральная Дедукция.

Есть 2 популярные теории типов - Martin-Löf type theory (MLTT) и Calculus of Construction (CoC). Они примерно одинаковой мощности и имеют скорее культурную\территориальную разницу. Тем не менее, Calculus of Construction немного новее и компактнее, а также используется двумя самыми популярными в индустрии теорем-пруверами - Coq и Lean. А еще по ней есть супер-качественный и новый учебник от Роба Недерпелта (Type Theory and Formal Proof: An Introduction). Поэтому я выбрал именно ее.

Собственно, 80% моих усилий по изучению фундамента математики на протяжении последних двух лет построены вокруг этой офигенной книги. Авторы книги проделали огромную работу и проанализировали 147 источников (другие книги и статьи), чтобы собрать все самое лучшее в одном месте. Благодаря их труду, я освоил эту область всего за 2 года вместо 10 лет. Я прорешал почти всю книгу и почти все упражнения, полностью покрыв первые 13 глав (300 страниц) книги. Эта книга строит фундамент математики с полного нуля и объясняет\формально вводит вообще все концепции и нотации. Одна из интересных особенностей книги в том, что автор использует современный конструктивный подход и выражает математическую логику полностью конструктивным способом, не использовав таблицу истинности ни разу. Это очень хорошо для обучения и понимания, а также наглядно показывает, как теория типов может переплетаться с математической логикой и чем на самом деле являются многие логические операции на низком уровне.

Можно разбить содержимое книги на 3 части - в первой части (1 - 6 главы) автор с полного нуля (с лямбда-исчисления) постепенно достраивает и усложняет систему типов и проходится по всему лямбда-кубу, чтобы получить в итоге золотую классику - Calculus of Constructions (λC). Во второй части (7 - 13 главы) - автор рассказывает, как запихнуть в эту теорию типов математическую логику и теорию множеств. В третьей части (14 - 15 главы) автор формализует целые числа (Z) и их арифметику внутри теории типов, дает основы теории чисел, а также формализует доказательство теоремы Безу в качестве демонстрации работы системы типов.

Собственно, главы 1-7 я прорешал на бумаге (со 100%-м покрытием всех упражнений в конце глав), потом я написал маленькое мобильное приложение под андроид (MathConstructor) и в нем покрыл главы 5,6,7 и 11. Главы 11-13 я покрыл уже внутри Coq, исходники можете найти в моем GitHub. И это получилось очень круто и полезно и эффективно! А на 14-15 главы у меня не хватило мотивации, т.к. в 13-й главе автор не очень чисто покрыл теорию множеств. Он решил использовать гибридный подход (с костылями внедрить многие концепции теории множеств в теорию типов, вместо того, чтобы чисто выводить все из аксиом ZFC). Мне это совсем не понравилось и пришлось переключиться на другой учебник по теории множеств.

Собтсвенно, после 13й главы я рекомендую вам переключиться на книгу по теории множеств

Собственно, я взял старый и классический учебник по теории множеств от 1963 года (Set theory and logic by Robert Stoll), и сразу прыгнул на 7 главу (Informal Axiomatic Set Theory), которая дает аксиомы ZFC и выводит из них множество натуральных чисел и его базовые свойства, и формализовал примерно половину главы за месяц. Это была проверка теории типов и Coq на прочность - и проверка успешно пройдена! Я был поражен тем, насколько автор 1963 года все четко излагает. Даже самые странные его утверждения и математические конструкции оказались очень нужны и полезны при формализации. Все его шаги, 100% ход мыслей можно 1-1 перенести на формальный язык теории типов. В общем, мне опять повезло с книгой, хоть там и много технических опечаток, но они - не проблема. Я точно уверен, что вернусь к этой книге еще.

В итоге, мне всего за месяц удалось закрыть огромное количество "серых зон" и пробелов в понимании ключевых математических концепций, которые у меня образовались в 2021 - 2022 году по мере прохождения различных стандартных математических курсов типа Calculus I / II / III. Мне удалось доказать существование множества натуральных чисел (N) - вытащить его из аксиомы бесконечности (ZF_Infinity), а также вывести 5 аксиом Пиано (на них все числовые системы строятся), а еще вывести принцип математической индукции, а из него - вывести принцип сильной индукции. Еще мне удалось из общей аксиомы выбора (ZF7_Choice) вывести частную аксиому выбора (более удобную), а из нее (используя теорему Диаконеску) вывести аксиому исключения среднего (excluding third), на которой базируется вся неконструктивная (классическая) математика. И все это очень интересно и полезно. Многие аксиомы для меня больше не являются аксиомами, а выводятся из 9 аксиом ZFC. Мне очень нравиться такой подход. Возможно, мне близка философия логистов и формалистов.

В итоге, на основе этих двух книг по теории типов и теории множеств, мне удалось заложить основы собственной библиотеки Coq, которая написана полностью с нуля и которую я понимаю на 100% как она работает изнутри. Я долго думал, как ее назвать, и ChatGPT предложил мне название ZFCFramework. Так и назовем ее. Собственно, в ближайшие пару лет я планирую ее активно развивать и наращивать, применять для разных обучающих целей. Очень круто, что у меня теперь есть такой инструмент. Если я буду погружаться в разные разделы математики и проходить новые курсы, я могу параллельно формализовать их в Coq и усиливать фундамент, а также получать максимальный выхлоп и максимально глубокий результат от потраченных сил на курсы или учебники.

По поводу моего мобильного Android-приложения MathConstructor: я пока его нигде не выкладывал, но планирую выложить где-нибудь в 2025 году вместе со всеми исходниками, и под это будет отдельная статья. Но вам не обязательно ждать - вы можете разработать свой аналог - и это совсем не трудно! На разработку рабочей Calculus of Constructions мне понадобилось всего 4 дня, и главы 5-6-7 уже почти полностью покрывались. Еще две недели понадобилось на баг-фикс, всякие удобства и допиливания λC до λD. Как говорил Кнут, "Лучший способ в чём-то разобраться до конца — это попробовать научить этому компьютер". Именно разработка приложения с нуля даст вам 100%-е понимание материала, а если вы будете использовать мое приложение - то только 90-95%. Возьмите шрифт Euler и любой HTML-движок, и этого достаточно для представления любого материала из книги.

Если вы достаточно умный и смелый - можете сразу же прыгнуть на главу 11 в книге по теории типов и программировать математическую логику/решать логические задачи внутри Coq, и возвращаться на предыдущие главы по мере возникновения вопросов. И использовать мои исходники, в которых я на 100% формализовал все содержимое главы и все упражнения в конце главы, для справки и при возникновении трудностей. У меня получилось 700 строк кода, это не очень много. Тут надо еще заметить, что я полностью отключил стандартную библиотеку Coq (опция '-noinit'), а также не использовал индуктивные типы, которые очень популярны в сообществе Coq-loving mathematicians.

По поводу первой главы - она довольно емкая и дает основы лямбда-исчисления. Весьма желательно прорешать ее на бумаге, если вы не имели опыта с теорией лямбда-исчисления. Coq не совместим с Untyped lambda calculus, так что его не получится использовать для самопроверки. Если вы знаете среду (или язык программирования), которые совместимы с не типизированным лямбда исчислением и позволят формализовать содержимое главы в них и проводить вычисления\проверки, то обязательно напишите об этом в комментариях. Если сможете прорешать первую главу в такой среде - обязательно выложите исходники и пришлите мне ссылку. Я бы сам не прочь вернуться на первую главу и повторить материал.

А что касается аксиоматической теории множеств (ZFC), то у нее есть очень много преимуществ и есть сильная мотивация для ее освоения. ZFC появилась 100 лет назад и на протяжении века все разделы математики были корнями под нее подведены. Любой классический учебник математики можно к ней свести 1-1, даже если неявно на нее не ссылаются. Конечно, есть и другие теории множеств. Например, проект Mizar использует теорию множеств Тарского–Гротендика (TG), и она немного посильнее ZFC. Но у меня пока не попадалось реальных случаев, когда бы не хватало ZFC.

Если вы хотите короткую серию из вводных лекций по ZFC, я могу вам порекомендовать плейлист от Ричарда Борчердса на YouTube. Он - один из самых крутых математиков в мире, получал Филдсовскую премию в 1998 году — одну из самых престижных наград в математике (ее часто называют «Нобелевская премия для математиков»). Ричард записал бесплатную серию из 8 видеоуроков и разборал все аксиомы ZFC, довольно четко и емко. Я полностью посмотрел и законспектировал его в 2023 году за полторы недели.

Математику часто делят на 2 типа - вычислительную (нахождение производных\решение уравнений и так далее), а также на аксиоматическую (proof-based/rigorous). Именно второй тип является "настоящей" математикой. Можете почитать про математическую зрелось (Mathematical maturity) и теория типов как раз помогает ее гарантированно достичь. Терренс Тао предложил разделить математическое образование на 3 этапа - Pre-rigorous/Rigorous/Post-rigorous. Собственно, формализация математики помогает максимально и идеально прокачать второй этап (Rigorous), и именно на нем обычно застревают большинство студентов.

Я довольно хорошо учился в универе на IT-факультете (Институт вычислительных систем и программирования (Институт 4) в СПБ ГУАП), и даже получал награду «Студент года ГУАП - 2017». В целом, там была хорошая образовательная программа, но некоторые моменты можно точно улучшить на уровне ГОСТ-стандартов. Один из таких моментов - это слишком много лекций по теоретическим предметам и отсутствие семинаров по ним с акцентом на покрытие (построение) теории. Пример 1 - у нас был предмет "Абстрактная Алгебра", который был мне интересен. Но семинары по ней не соответствовали тому, что давалось на лекциях - на них мы решали вычислительные задачи вместо доказательства теорем с нуля. Пример 2 - у нас был предмет "Математический Анализ", но на семинарах мы тоже решали вычислительные задачи в большом количестве - нахождение производных и интегралов. Мне кажется, это пережиток прошлого и ГОСТ нужно менять. Лекции, как формат обучения, нужно вообще выпилить. Они имеют очень мало смысла в современном мире. Всегда можно найти записи и просмотр лекции вживую - это, по сути, тоже самое, что и просмотр записи онлайн, только неудобен и будет почти всегда ниже по качеству, чем хорошо подготовленная запись. Вместо лекций, нужно делать много-много семинаров с небольшими группами студентов по 5-8 человек. Профессор на семинаре может давать тот же материал, что и на лекции, но выводить и доказывать его одновременно со студентами, и делать паузы\давать студентам возможность быть частью этого процесса. Это будет дороже для ВУЗа, но разница вряд ли будет ощутима для руководства.

Еще нужно предупредить вас об одном заблуждении, которое весьма распространено как на Хабре, так и (по всей видимости) среди студентов. Существует пресловутая теорема Геделя о неполноте, которая звучит так: в любой достаточно мощной формальной системе существуют истинные утверждения, которые нельзя доказать в рамках этой системы. И я часто встречал некорректную (неправильную) интерпретацию этой теоремы. Некоторым кажется, что из этой теоремы следует невозможность создания единого фундамента, из которого все выводится. Но ведь такой фундамент есть и уже сто лет существует - и это 9 аксиом ZFC! Можете спросить у ChatGPT, "Какие разделы математики невозможно формализовать в ZFC?" - и он вам накинет весьма редкие случаи, половина из которых (внезапно) из разных глубоких разделов теории множеств. Если вы столкнетесь с этими редкими случаями, вы можете просто накинуть дополнительные аксиомы к ZFC. Например, гипотеза континуума (CH) - вполне себе кандидат на добавление в ZFC, но ее не стали добавлять, т.к. она просто никому особо не нужна. Я не проверял, но полагаю, что можно вывести все ключевые теоремы и утверждения о современных нейронных сетях, и гипотеза континуума при этом не будет использована.

До 2023 года, моей главной целю в изучении теории\фундамента математики было разобраться в фундаменте высокоуровневых математических дисциплин - теории вероятности и математической статистике. Под ними лежит довольно длинный математический стек. Начиная с 2023 года, я переключил главную цель на "разобраться в фундаменте AI". Как выяснилось, эти цели почти полностью совпадают. На основе теории типов вы строим математическую логику, далее на основе логики - строим теорию множеств, затем переходим к построению числовых систем и доказываем существование натуральных чисел на основе аксиомы о бесконечности, далее строим целые и рациональные числа на основе натуральных чисел. После этого можно построить множество вещественных чисел на основе рациональных чисел и перейти к анализу вещественных чисел. Далее, переходим к теории измерений и строим теорию вероятности на ее основе. Далее, независимо от всего этого можно вывести линейную алгебру из теории вероятности. Когда у нас есть теория вероятности и линейная алгебра, можно переходить к математической статистике, а после нее - уже строить конкретные модели нейронных сетей.

Чтобы понять, на каком фундаменте построено современное машинное обучение - можно ссылаться на курсы Mathematics for Machine Learning Specialization (Coursera) и Mathematics of Machine Learning (MIT). Видим, что в списке фигурирует Real Analysis/Linear Algebra/Probability/Statistics/Multivariate Calculus/PCA. У меня сложилось впечатление, что самым важным из этого списка является Real Analysis (вещественный анализ, на русском языке часто его называют просто "математический анализ" или матан), а Calculus III (мультивариативное исчисление) и Probability (теория вероятности) из него выводятся. А статистика, точнее самая вкусная ее часть, выводится из теории вероятности.

Таким образом, центральной задачей в освоении фундамента машинного обучения является формализация математического анализа. Эта задача не нова и решилась еще в 1977 году, когда один студент (аспирант) использовал теорем-прувер Automath, чтобы формализовать учебник "Основы анализа" (Foundations of Analysis) Эдмунда Ландау и защитил диссертацию на эту тему. Как оказалось, математический анализ очень даже хорошо формализуется. Это очень важный предмет, для понимания которого как раз требуется мыслить через строгую математическую логику, и многие вузы используют его для отсеивания студентов, которые не осилили формальные методы мышления и вместо этого мыслят эмоционально и живут животными инстинктами.

Среди западных авторов, есть 3 хороших учебника по математическому анализу. Самый классический - это Principles of Mathematical Analysis by Walter Rudin, он чаще всего используется в англоязычных технических вузах. Он хорош с точки зрения формальной подачи, глубины проработки и сложных упражнений. Главный недостаток для меня в том, что он аксиоматически задает множество вещественных чисел R (11 аксиом поля и аксиома полноты), вместо того, чтобы выводить все из теории множеств. В этом есть свои плюсы, тк строить всю цепочку числовых систем может отнять много сил и времени. Например, в другом учебнике (Analysis I by Terrence Tao), автор тратит первые 100 страниц книги, чтобы построить числовые системы (N -> Z -> Q -> R) на основе аксиом Пиано. Есть еще книга Understanding Analysis by Stephen Abbott, и у нее очень высокая популярность среди современных студентов (судя по отзывам на амазон). Я прорешал первую главу в 2022 году, но мне она не зашла, т.к. она слишком неформальная и слишком много пробелов\дыр в понимании оставляет. Я бы предпочел потратить в 3-5х больше усилий и пройти книгу Рудина или Терренса, но получить хороший результат без пробелов в понимании.

Собственно, книга Set theory and logic by Robert Stoll от 1963 года тоже строит всю цепочку числовых систем (N -> Z -> Q -> R). Но, как мне кажется, Терренс Тао делает это более подробно и потом плавно перетекает в теоремы анализа, ряды и интегралы. Скорее всего, я пойду именно этим путем, т.к. на основе рядов и интегралов можно потом строить теорию вероятности. Например, в книге A First Look at Rigorous Probability Theory by Jeff Rosenthal, есть раздел "A. Mathematical Background", и автор рекомендует использовать его как измерение "входного порога" (пропускной экзамен) в аксиоматическую теорию вероятности. Если вы чувствуете себя комфортно в тех темах, что там указаны - можно переходить к этой книге. Собственно, там половина - теория множеств, а другая половина - это ряды и свойства вещественных чисел.

Входной порог в аксиоматическую теорию вероятности - что требуется знать
85b3d55dd837548442d2dca52e154af6.png

Есть 2 способа формализовать множество вещественных чисел (R) - через разрез Дедекина (дается в книге Рудина и Столла) и через последовательность Коши (дается в книге Терренса). Я пока не разобрался в этой теме, но, скорее всего, пойду по второму пути (Cauchy sequences), т.к. это более чистый и современный подход, а также последовательности\ряды более релевантны к фундаменту теории вероятности. Но любой способ подойдет, главное, чтобы на итоговом множестве работали (выводились) аксиомы поля, порядка и полноты.

Что касается линейной алгебры - тут можно ссылаться на учебник Linear Algebra Done Right by Sheldon Axler. Если хотите посмотреть конкретную демку, как главы этой книги формализовать внутри Coq, можете посмотреть плейлист Linear Algebra Done Right in Coq, в котором профессор Квин записал 50 часов видеоуроков. Это может повысить вашу мотивацию и дать конкретный пример. Я планирую повторить тоже самое, но мой фундамент математики будет более чистый (без индуктивных типов), а также полностью выводиться из ZFC.

А если вам нужен хороший курс по Calculus III (мультивариативное исчисление), то я могу порекомендовать курс на Educator (23 часа, довольно емкий и приятный). Я его полностью прошел пару лет назад и научился брать тройные интегралы на бумаге параллельно с автором.

Далее, нужно выяснить, на каком математическом фундаменте построен ChaptGPT. Тут можно ссылаться на курс Neural Networks: Zero to Hero, в котором автор строит GPT-2 с нуля. У меня сложилось впечатление, что математический фундамент генеративных нейронных сетей (внезапно) не отличается от обычных нейронных сетей и уходит корнями в классическое машинное обучение. Но я глубоко не копал эту область, и если я не прав, просьба в комментариях подробно раскрыть эту тему.

Тут надо заметить, что конечный результат работы генеративных нейронных сетей на данный момент является чем-то типа черного ящика и (насколько я понял) не формализуется. Я думаю, это вопрос времени. Программирование тоже когда-то считалось скорее искусством, чем наукой. А потом пришел Кнут и подвел четкий математический фундамент под анализ сложности и корректности алгоритмов, переиспользовав при этом существующий математический аппарат алгебры\исчисления\теории множеств и теории графов, а также украв нотацию O большого у Ландау. Я уверен, что с нейронными сетями произойдет тоже самое. Я на 80% уверен, что там будут переиспользованны какие-то существующие разделы математики, которые уже существуют и полностью совместимы с ZFC. Я на 95% уверен, что даже если появятся новые разделы математики, то их сделают совместимыми с ZFC. Я на 99% процентов уверен, что даже если и появится новый фундамент математики, то его можно будет выразить внутри теории типов и формализовать внутри Coq.

Также, есть интересная книжка Neural Networks from Scratch (https://nnfs.io/), в котором авторы используют только питон и его стандартные библиотеки, чтобы построить простые нейронные сети. Я ее пока не пробовал, но планирую в обязательном порядке попробовать в будущем. Для обучения, именно такие подходы максимально хороши.

Если вам интересна тема прохождения онлайн-курсов в целом, то я на прошлой работе (когда работал в Сравни Java-разработчиком) записал большой митап на эту тему, можете посмотреть запись вот тут. А сейчас, я работаю в EDNA Java-разработчиком.

Анонс моего митапа по онлайн-курсам

Это Ярослав, Java-разработчик из команды Core/AF. Месяц назад я сделал опрос на тему "Кому интересны онлайн-курсы?", и увидел большую заинтересованность. Я и Aleksey Dolgushev за месяц проделали большую работу и подготовили интересный и объемный доклад. Уже в эту среду (завтра) с 12.00 до 13.00 будет сама презентация [Sravni Tech Meetup], я проведу ее удаленно для вас (30 минут сам доклад и 30 минут отвечаю на ваши вопросы). В докладе хочу поделиться опытом: за 5 лет я прошел (полностью) более 15 онлайн-курсов; площадки: Coursera, Educator и TeachIn (МГУ). На встрече обсудим:
- Зачем вообще проходить онлайн-курсы; какая от этого польза
- Демотиваторы, которые мешают людям проходить курсы
- Про полноценное онлайн-образование удаленно от топовых ВУЗов мира
- Куда смотреть, где живут правильные курсы
- Как подобрать хороший курс
- Лайфхаки: как получить бесплатный доступ к платному контенту, как не бросить курс в процессе и другие советы

А теперь давайте поглубже поговорим о теории типов. Собственно, Роб в своей книге приводит 11 простых правил выведения типов, которые очень легко запрограммировать и на которых все построено. Он утверждает, что можно взять любой классический учебник по математике и полностью его алгоритмизировать. Любой ход мыслей любого математика, даже самого умного и сложного, можно представить в виде цепочки из N применений этих правил. Если вы взяли любой учебник по теории и не можете каждый его шаг транслировать в маленькие шаги и свести все к логике - то ваша подготовка недостаточно глубокая. Любой (достаточно глубокий) учебник математики = определения + выведение новых результатов на основе предыдущих + небольшое текстовое описание, которое можно выкинуть.

Список из 11 правил выведения типов, на которых все построено
4994b64c11864ad8c6ab98a20fb4920c.png

Можете провести параллель с документацией Coq, в которой описано 19 правил выведения обычных типов и еще вот тут 4 правила для выведения индуктивных типов. Coq сильно расширил базовые правила, чтобы было удобнее сопровождать большие проекты по формальной верификации ПО, но при этом остался совместим с золотой классикой исчисления конструкций (Calculus of Constructions).

У читателя может возникнуть вопрос - почему именно 11 правил выведения типов? Может ли их быть меньше? Да, может, есть PTS (Pure Type System), которая стирает границу между термином и типом. Также, есть комбинаторная логика, в которой всего 3 символа (комбинатора) S, K и I. Было доказано, что любые правила выведения типов можно свести с этим 3-м комбинаторам и комбинациям из них. Если вы хотите особо подзапариться, то можете написать движок комбинаторной логики, в которой вы построите 11 правил выведения типов λD на основе этих комбинаторов, а на них уже дальше будете строить все остальное и делать упражнения из книги. Но, на мой взгляд, это уже оверкилл, тк 11 правил λD весьма просты к реализации и пониманию, а также на них основаны теорем-пруверы Coq и Lean, так что имеет смысл брать именно 11 правил λD за основу.

Тут нужно также заметить, что на каждом этапе можно "срезать углы" и вместо того, чтобы выводить что-то, можно просто заткнуть дырку аксиомой. Это очень плохо для обучения и глубины понимания, но нужно иметь в виду, что такой подход есть:

  1. Вместо того, чтобы выводить правила и концепции математической логики из теории типов, можно просто накинуть десяток-другой аксиом. Например, для конъюнкции (A ∧ B) будет 4 аксиомы - одна постулирует существование самой конъюнкции как типа, еще одна на основе A и B выводит (A ∧ B), а другие две на основе (A ∧ B) вытаскивают А и вытаскивают B. Если вы хотите по-быстрому разработать свой теорем-прувер на основе логики первого порядка, можете пойти по этому пути. Но лучше все-таки разобрать правила выведения типов и на их основе все сделать.

  2. Вместо того, чтобы выводить аксиомы Пиано (5 штук) из аксиом ZFC, можно просто их постулировать как аксиомы. Например, Терренс Тао поступает именно так в начале своей книги Analysis I, а иначе его книга могла бы увеличиться в полтора раза.

  3. Вместо того, чтобы выводить всякие концепции типа "пара (a, b)", ее свойство и существование декартова произведения и из теории множеств, можно просто принять их как примитивные и добавить как аксиомы

  4. Вместо того, чтобы выводить всю цепочку числовых систем (N -> Z -> Q -> R), можно сразу же перейти к свойствам R и постулировать существование множества R и аксиомы на нем (поле + порядок + полнота). Многие курсы по математическому анализу именно так и поступают.

  5. Любую слишком большую и толстую теорему в теории вероятности или статистике можно принять на веру и добавить, как аксиому. Собственно, многие курсы и учебники по статистике так и поступают для большинства теорем

Математиков можно поделить на 2 большие группы - алгебраисты и аналисты. Тут можно ссылаться на эксперимент с кукурузкой, в котором показали, что представители этих двух направлений едят кукурузку по-разному. Мне кажется, что большая часть программистов в индустрии - это алгебраисты, а большая часть статистов/дата-саентистов - это аналисты. Собственно, школьный предмет "Алгебра и начала анализа" знакомит с основами этих двух направлений. Когда я учился в школе, мне нравилось примерно 60% от того, что мы делали на школьной математике (алгебраическая часть), и я не любил другие 40% (аналитическая часть). Собственно, сейчас я как раз развиваю аналитическое мышление и надеюсь, что мои увлечения фундаментом математики помогут мне овладеть одновременно двумя этими направлениями и есть кукурузку так, как я захочу.

Мне всегда было интересно, как именно происходит переход от алгебраической формы (N = A ∪ ∅) к аналитической форме (p -> q -> r). На форумах (StackOverflow / Quora) писали, что вся математика может сводиться к небольшому набору аксиом и любое математическое высказывание можно трассировать в виде огромного дерева логических выводов (импликаций), но мне было непонятно, как именно алгебраическая форма вписывается в это дерево. Собственно, в главе 12 "Mathematics in λD: a first attempt" Роб Недерпелт раскрыл этот механизм и ввел йота-дескрипторы. Получилось очень компактно и аккуратно, всего в 6 строчек вписалось. Он добавил их как 2 "псевдоаксиомы" (примитивные определения), но по сути они не являются аксиомами и не делают теорию типов логически сильнее (и это было доказано). То, что они реально делают - они добавляют "математический сахар" для тех математических объектов, которые (было доказано) существуют и уникальны. Например, вы можете доказать 1 раз, что существует пустое множество и притом только одно, назвать теорему empty_set_unique, и потом ссылаться на это множество через (ι _ (empty_set_unique)): Set. Далее, вы прячете эту йоту под термин ∅, и используете ее так, как ее принято использовать во всех математических текстах. Если вам понадобиться свойство пустого множества, вы можете развернуть термин ∅ обратно в йоту и из нее вытащить свойство.

Собственно, во всех классических математических текстах используют йота-дескрипторы в неявном виде. Даже ваш школьный учитель математики использовал его много раз на доске, когда писал N и ссылался на уникальное множество натуральных чисел. Под ним прячется йота, а под йотой - доказательство существования этого множества и его уникальности.

Как выглядит йота-дескриптор и его свойство
cb362e6b495b505ac68d53c95a09b6cf.png

Можно также посмотреть, как в стандартной библиотеке Coq определяются йота-дескрипторы. По сути, там тоже самое, но усложненно через использование дополнительных определений и индуктивных типов. Для обучения и понимания\первого знакомства, это усложнение вообще не нужно и сбивает с толку. Это еще одна причина, по которой лучше обучаться по учебнику с акцентом на чистую теорию, а потом уже переходить к конкретной имплементации.

Еще один интересный и простой пример - что такое массив? Что вы видите, как программист, когда думаете о массиве [a, b, c], но без учета порядка элементов? Я всегда видел 3 ячейки в памяти (по 4 байта каждая), которые хранят переменные a, b, c друг за другом. А теперь, я вижу другое - я вижу логическое выражение ∃b. ∀x. ((x ∈ b) ⇔ (x = a ∨ x = b ∨ x = c))). А если учитывать порядок, то это будет функция (множество пар), которая проецирует множество {0, 1, 2} на множество {a, b, c}, т.е. ∃b. ∀p. ((p ∈ b) ⇔ (p = <0, a> ∨ p = <1, b> ∨ p = <2, c> ))). А пару, тоже можно выразить через множество. В общем, в IT все отлично формализуется.

Формализованную математику еще иногда называют механизированной математикой (mechanically checked mathematics). Если вам близок инженерный подход, можете представлять себе математику как огромный завод, на котором в качестве сырья выступает набор из 9 аксиом, а в качестве стандарта сборки - 11 правил выведения типов. Небольшие фабрики производят из этого сырья пруф-объекты, и потом катят эти пруф-объекты по ленте к другим фабрикам. Возможно, я переиграл в Satisfactory.

Тут надо еще заметить, что математику (исторически) принято изучать от конкретного к общему. Сначала нужно освоить исчисление (Calculus), понять его применения и выработать интуицию вокруг вычисления конкретных математических объектов и решения конкретных задач, а уже потом переходить к анализу вещественных чисел (Real Analysis). Тут можно ссылаться на провальный эксперимент New Math в США в 1970 году, когда попытались внедрить фундамент математики (теорию множеств и символическую логику) в школьную программу, и заменить ими унылое заучивание таблицы умножения\решение уравнений и так далее. Как выяснилось, это плохая идея - сначала нужно все-таки сформировать некоторую грязную базу и потратить силы\время на нее (и это наверняка вызовет дискомфорт), а уже потом переходить к чему-то более абстрактному и чистому.

А теперь поговорим о технических инструментах, которое реализуют внутри себя теорию типов и решают различные практические задачи. Начнем с Coq (он же The Rocq Prover). Он - классика в области формализации математики и формальной верификации ПО. Coq появился в 1984 году и занял эту нишу довольно плотно. Есть и более новый конкурент у Coq - это Lean. Но я не нашел достаточно мотивации, чтобы взять его с самого начала или перейти на него:

  1. Lean построен на той же теории типов, что и Coq, а значит фундаментальных плюсов у него нет.

  2. В документации по Lean я не нашел строгую формулировку правил выведений типов (которая есть у Coq), и это плохой знак.

  3. Lean моложе Coq на 24 года, а значит сообщество и экосистема намного меньше, а также база решенных проблем и применений намного тоньше. Например, у реддита Coq 2500 участников, а у реддита Lean - всего 390.

  4. В Coq вливает много денег большой государственный исследовательский центр во франции (INRIA), а Lean - финансирует небольшой исследовательский отдел Microsoft (но тут я могу ошибаться).

  5. У Coq есть 6-томник "Software Foundations". Ради одного только его я мог бы выбрать Coq

b0a72a834d6d6e161584978ccd483371.png

Я выбрал Coq вместо Lean примерно по тем же причинам, по которым я когда-то выбрал Java вместо С#. Но кроме Coq и Lean, есть и другие теорем-пруверы. Isabelle/ZF и Metamath тоже все выводят из ZFC, но я их не выбрал в силу их малой популярности, а также слишком кастомного ядра и отсутствия строгой фундаментальной теоретический базы.

У нас есть 3 возможных уровня применения теории типов для формализация математики:

  1. Уровень 1 - мы используем теорию типов только как движок для математической логики, а дальше про нее забываем и работаем полностью внутри математической логики и выводим все математические структуры из аксиоматической теории множеств. Этот подход самый трудозатратный, но он дает самый лучший результат для обучения и глубокого понимания. Поскольку моя цель - это как раз обучение и понимание, я придерживаюсь только этого подхода.

  2. Уровень 2 - мы используем теорию типов не только как движок, но еще и перекидываем некоторые фрагменты теории множеств в нее. Результат получается намного более компактным и удобным для практических задач верификации, но не очень хорош для обучения. Например, вместо того, чтобы выводить множество натуральных чисел из аксиомы бесконечности, мы можем представить натуральные числа как индуктивный тип, или хитро ввести их через йоту. Таким подходом пользуется Роб Недерпелт в его главе по теории множеств, а также он используется в стандартной библиотеке Coq. Мне совсем не нравиться этот подход, так как он ломается на всяких штуках типа "как представить подмножество?" или "как представить множество всех подмножеств (powerset)?" и там приходится костылить.

  3. Уровень 3 - мы полностью переходим в теорию типов и используем ее не только как фундамент для логики, но еще и как фундамент для математических структур. Тут можно отметить работу нашего соотечественника Владимира Воеводского, который развивал гомотопическую теорию типов и даже основал библиотеку Coq для нее. Но это исследовательская область, и у меня пока нет мотивации в нее погружаться. Она настолько не готова, что даже в начале учебника по гомотопической теории типов написано, что теория в процессе изменений и все может поменяться. Возможно, я когда-нибудь посмотрю курс лекций по теории гомотопии и попробую разобраться, как именно она стыкуется с теорией типов и где это можно применить в моих задачах.

Если вам интересны конкретные применения Coq для решения реальных задач, то можно ссылаться на CompCert - полностью формально верифицированный компилятор языка С. Во время его формализации, исследователи нашли и поправили 100+ критических багов, и как результат - самолеты летают более надежно. Еще есть более свежий проект - CertiKOS, полностью формально верифицированная операционная система, которую невозможно взломать логическими методами. Ее формальная верификация заняла 1 миллион строк кода на Coq. Еще Coq используется в верификации всяких штук в инфобезе типа TLS-протокола.

Работа по формальной верификации нейронных сетей тоже есть, и я уверен, что это направление будет очень сильно расти в ближайшем будущем. Люди очень боятся восстания машин, так что будут вливать много денег в то, чтобы сделать AI безопасным и надежным. Чтобы дать такую гарантию на 100% - нужны математические методы.

Если вас интересует ситуация в индустрии теорем-пруверов в целом, то там все очень хорошо. Можно ссылаться на список из 100 самых популярных теорем и списка теорем-пруверов, в которых они доказаны. Видно, что суммарно покрытие составляет 99 теорем из 100 - каждая из них покрыта хотя бы в одном теорем-прувере, а на Coq приходится покрытие 79 теорем. Особое внимание можно уделить теореме-доказательстве иррациональности квадратного корня, которая играет ту же роль, что и "чайник" в 3D графике для проверки движков, и все теорем-пруверы ее доказывают. Также можно обратить внимание на теорему центрального предела (The Central Limit Theorem), которая покрыта только в теорем-прувере Isabelle. Сложилось впечатление, что она играет очень важную роль в математической статистике и я пообещал себе, что не вернусь к учебнику по статистике, пока эту теорему не формализую и не пойму до конца, как она работает изнутри.

Еще можно упомянуть проект QED manifesto, цель которого - формализовать и компьюторизовать вообще всю математику. Пока что QED utopia не была достигнута, но максимально к ней приблизился именно проект Mizar Mathematical Library. Я думаю, в будущем к этому проекту вернуться и благодаря AI смогут достичь QED-утопии. Можете почитать сам манифест, он написан довольно понятным языком и разбирает популярные заблуждения по поводу несовместимости логики, парадоксы и так далее. И аргументирует, что такой проект технически и логически достижим.

Я рекомендую всем, кто умеет программировать, пройти хотя бы первую главу первого тома "Logical Foundations". Она не требует специальной подготовки и займет у вас пару недель. В рамках этой главы, вы построите натуральные числа (N) на основе индуктивных типов, а также их базовые свойства (аксиомы Пиано), и базовые операции (сложение\умножение\возведение в степень\факториал). Также вы познакомитесь с принципом работы Coq и его базовыми тактиками.

Если вы - разработчик в индустрии, то вы, наверняка, привыкли писать императивные программы и лишь изредка использовать функциональное программирование. Хотя на некоторых работах может делаться акцент на функциональщине в силу специфики бизнеса и\или выбранного стека технологий. Например, мы в Edna используем проект Reactor и реактивный подход довольно часто, а на прошлых работах я часто применял Stream API. В случае Java у нас JVM и работа процессора является императивной по своей природе, а функциональное программирование эмулируется внутри императивной модели вычисления (RAM-модели). А вот в индустрии теорем-пруверов все наоборот - за основу взята теория типов на основе лямбда исчисления, которая является полностью чистой и функциональной. А императивный подход достигается путем введения языка тактик и автоматизации. Есть 2 способа программировать математические теоремы - напрямую через лямбды, а также через тактики, которые под капотом крутят эти лямбды. Любую теорему Coq можно представить в виде огромной мотни из лямбд. Команда "Show Proof." печатает вам пруф-объект (низкоуровневое доказательство теоремы). Coq правда любит прятать их, и нужно через небольшой лайфхак (Defined вместо Qed) определять теоремы, чтобы они не прятались.

Как выглядит доказательство правила Де-Моргана (¬(A ∧ B) ⇒ (¬A ∨ ¬B)) на самом низком уровне

fun (A B : Prop)(H : forall(_ : forall (C : Prop)(_ : forall (_ : A) (_ : B), C), C)(A0 : Prop), A0) =>exc_thrd A(forall (C : Prop)(_ : forall _ : forall (_ : A) (A0 : Prop), A0, C)(_ : forall _ : forall (_ : B) (A0 : Prop), A0, C), C)(exc_thrd B(forall (_ : A) (C : Prop)(_ : forall _ : forall (_ : A) (A0 : Prop), A0, C)(_ : forall _ : forall (_ : B) (A0 : Prop), A0, C),C)(fun (H2 : B) (H3 : A) =>H (fun (C : Prop) (h : forall (_ : A) (_ : B), C) =>h H3 H2)(forall (C : Prop)(_ : forall _ : forall (_ : A) (A0 : Prop), A0,C)(_ : forall _ : forall (_ : B) (A0 : Prop), A0,C), C))(fun (H2 : forall (_ : B) (A0 : Prop), A0) (_ : A)(C : Prop)(_ : forall _ : forall (_ : A) (A0 : Prop), A0, C)(H0 : forall _ : forall (_ : B) (A0 : Prop), A0, C)=> H0 H2))(fun (H2 : forall (_ : A) (A0 : Prop), A0) (C : Prop)(H0 : forall _ : forall (_ : A) (A0 : Prop), A0, C)(_ : forall _ : forall (_ : B) (A0 : Prop), A0, C) =>H0 H2)

Просвечивается exc_thrd - аксиома исключения среднего, через которую и идет доказательство (тк это правило в данной форме - не конструктивно). Других аксиом тут нет.

Собственно, fun - это лямбда и вводится через правило абстракции (abst). forall - это Π-тип, выводится через (form). Prop - можно заменить на звездочку.

Напечатал путем выполнения команды Eval cbv in deMorganNotAnd. Вот таким нехитрым способом, можно для любой теоремы, доказанной внутри Coq, получить ее лямбда-форму, развернув все определения.

Особый интерес представляет то, что все учебники из серии Software Foundations интерактивно читаются внутри IDE. Именно таким должен быть учебник математики будущего - на 100% механически формализован и верифицирован, подача учебного материала перемешена с упражнениями, а также есть среда выполнения и язык программирования, которые позволяют экспериментировать\проверять\выходить за рамки. Собственно, тут можно ссылаться на усилия Кевина Баззарда по внедрению теорем-прувера Lean в имперском колледже Лондона в математические программы (The Xena Project). Я очень поддерживаю такие штуки и думаю, что математическое образование будет именно таким на всех уровнях.

Есть два способа изучать математику - от учителя к ученику (классический подход), а также с компьютером и без учителя (новый подход). Конечно, было бы круто, если бы хорошие учителя были бы доступны по всем предметам, а ученикам было бы приятно и интересно проводить время с ними. Но на практике, есть огромное количество проблем у этого подхода. Они не только финансовые (хороший репетитор\ментор будет очень дорого стоить), но и привязаны к месту проживания (не всегда можно в принципе кого-то найти в доступности). А также очень трудно найти кого-то, с кем вам приятно и комфортно проводить время, чтобы человек вам нравился. По итогу, приходится развивать альтернативные направления. Одно из таких направлений - смотреть онлайн-курсы и видео, в которых у вас создается впечатление, что лектор общается с вами, и вы параллельно с ним прорешиваете задачи, как с репетитором. Другое направление - это всякие интерактивные среды и компиляторы\песочницы, которые строго ограничивают ваши действия и дают информативные сообщения об ошибках, если вы что-то делаете не так. В этом смысле, теорем-пруверы типа Coq являются "идеальным учителем" математики, который видит 100% ваших ошибок в логике и просто не даст вам двигаться дальше, если что-то сделано не так.

У меня есть гипотеза о том, что во время занятия (реальной) математикой у человека в голове формируется что-то типа теории типов на уровне нейронов. Я пока не могу подтвердить мои догадки и ссылаться на исследования из области нейронауки, но я верю в эту гипотезу и уверен, что в будущем что-то подобное будет экспериментально доказано.

Еще один лайфхак - если вы девушка и очень хотите войти в айти, то вы можете попробовать пожить с мужчиной, который работает программистом в айти компании (но не со мной) пару лет вместе. Если вы будете каждый день общаться на бытовые темы, вы будете перенимать ход мыслей и впитывать базовые идеи, даже если он вас не будет обучать в явном виде. Это супер-важно и может сильно вам помочь в развитии потом освоить язык программирования или профессию QA\HR. Но даже если вы ничего не освоите, у вас все равно есть шанс пробиться в айти на большую зарплату. Я периодически встречал коллег, которые ничего не знают\не умеют, но думают как знающий\умеющий человек (мимикрируют под программиста) и хорошо умеют проходить собесы.

А если вы мужчина, то ждите появления виртуальных учителей\менторов на основе GirlfriendGPT, они помогут вам решить главную проблему в образовании - проблему с мотивацией.

А теперь поговорим о теме "войти в IT". Главная причина, почему обычные люди не могут комфортно войти в айти и научиться программировать - это отсутствие математической подготовки и трудности с ее получением. Вот вам секрет, как сделать из обычного человека хорошего программиста: нужно потратить пару лет на школьную математику и подтянуть ее до уровня физ-мат школ, а уже после этого переходить к языкам программирования. А сразу прыгать на курсы или онлайн-системы типа JavaRush без уверенной математической базы - это очень плохая идея.

Если вам интересно, откуда я насобирал столько полезной информации по теме фундаментальной математики и связал все воедино, я могу раскрыть мои источники. Я уже 8 лет как активно использую английский Гугл (почти каждый день) и много с ним общаюсь на разные темы. Он дает мне ссылки на английскую википедию, а также на всякие сайты типа MathOverflow, Quora и Reddit. В 2024 ChatGPT созрел как замена Гуглу, поэтому в декабре я купил подписку ChatGPT Plus и перешел на него в качестве дефолтового поисковика в Chrome. Я планирую в 2025 полностью отказаться от Гугла и пользоваться только ChatGPT, переписываясь (или общаясь голосом) с ним на английском языке.

А теперь поговорим о списке практических применений фундаментальной математики. Список довольно большой и он только растет, у меня появляется все больше и больше разных креативных идей каждый месяц. Кажется, у меня все расписано на ближайшие 10 лет и все мое развитие и рост в будущем (как личный, так и профессиональный) будут затрагивать теорию типов\теорию множеств\теорем-пруверы.

Применение #1: Войти в AI/ML и сделать это по-царски. По опыту с компьютерными науками я знаю, что чем глубже подготовка по теории - тем лучше. Это не только входной порог, но еще и задел на развитие, более широкий выбор из компаний, возможность миграции внутри компании, гибкость в развитии и резистентность к сокращению. Где-нибудь в 2026-2027 году я буду готов и сразу возьму какие-нибудь крутые курсы с Курсеры или MIT OpenCourseWare по AI. Совсем не обязательно полностью формализовать весь фундамент под AI/ML. Я думаю, что глубокое понимание и формализация некоторых ключевых теорем в анализе и теории вероятности будет более чем достаточно.

Применение #2: Алгоритмы и структуры данных, их анализ и формализация. Собственно, я уже итак довольно глубоко проработал эту область и прошел 2/4 курса из специализации на Курсере по дизайну и анализу алгоритмов от Стендфордского университета в 2022 году. Моя главная цель - это не только комфортное прохождение алгоритмических собесов и сильная позиция на рынке, но еще и возможность брать более крутые и интересные задачи. Я пока не знаю, как именно буду продвигаться дальше, но я точно знаю, что хочу формализовать машину Тьюринга внутри ZFC и научиться ее там крутить, а также разобраться, как именно RAM-модель (математический ассемблер) компилируется в машину Тьюринга . Если это сделать, то можно добиться 100-го понимания самой концепции алгоритма и, как результат, получить большой бонус к решению алгоритмических задач. Будет идеально, если я смогу на LeetCode решать алгоритмические задачи одновременно на двух языках - математическая модель и доказательство корректности\сложности на Coq, и быстрая имплементация алгоритма на Java.

Входной порог в алгоритмы и структуры данных - что требуется знать
bd4cfb5f07cc768c641043489004deb2.png

Взял из CLRS

Тут еще надо заметить, что среди программистов в России очень много слабых IT-специалистов с очень слабой математической подготовкой, которые решают весьма рутинные и неинтересные задачи в проектах с кодовой базой плохого качества, а также не хотят изучать что-то новое и вкладываться в развитие. Такой путь развития и раньше был не перспективен, а теперь (с учетом изменений в мире AI) кажется совсем провальным и я вам крайне не рекомендую прислушиваться к мнению таких знакомых, если они у вас есть.

Применение #3: Формализация программного обеспечения. Как я уже писал, Coq активно используется в индустрии для того, чтобы доказать корректность работы программ и вообще любых IT-систем. Я изначально думал, что это слишком узкое направление и в целом не очень полезное для карьеры Java-разработчика. Сейчас я так не считаю. В моей работе регулярно встречаются ситуации, которые критически важны для бизнеса и которые прямо таки напрашиваются, чтобы их формализовали. Формализация позволит не только дать более четкий\аргументированный ответ бизнесу (актуально для техлида), но и предотвратить инцеденты на проде (и отдыхать вместо того, чтобы их исправлять). Например, микросервисное взаимодействие и некоторые архитектурные паттерны прямо так и напрашиваются, чтобы их формализовали. Компании тратят куча денег и ошибки - стоят очень дорого. Лучше убедить бизнес, чтобы эти деньги положили Java-разработчику в карман.

Собственно, я полтора года назад прорешал первые 6 глав на 100% в учебнике Logical Foundations, но застрял на главе "Inductively Defined Propositions", тк она (по всей видимости) - повышенного уровня сложности. На тот момент у меня не было такой глубокой теоретической подготовки, как сейчас. Сейчас я могу вернуться и закончить первый том. В ближайшие пару лет сделаю, если не будет более интересных приоритетов.

Применение #4: Формализация баз данных. Базы данных используют вообще все специалисты в IT (даже менеджеры), и возникает очевидный вопрос - а как формализовать реляционные БД? В 2021 году я наткнулся на очень крутую книгу Applied Mathematics for Database Professionals by Lex deHaan, в которой авторы очень чисто формализуют современную БД и язык SQL в терминах математической логики и теории множеств. Эта книга была для меня большим открытием и я довольно быстро и комфортно прорешал первые 8 глав и упражнения к ним на бумаге. Она не только покрывает простые CRUD-операции, но и более сложные темы, такие как структура БД, ее ограничения и транзакции.

Собственно, это очень полезно для более глубокого понимания логической сути БД (что в БД важно, а что второстепенно), помогает не утонуть в деталях имплементации конкретной БД, а сконцентрироваться на ключевых моментах и более грамотно проектировать БД.

Пример Select и его формальная форма на языке теории множеств

select distinct e.JOB from EMP e where e.MSAL > 4800 or e.SGRADE >= 6

Входной порог в теорию БД - что требуется знать
9605a7f663df2ac8104c08aebef7dbd5.png

Применение #5: Развитие в менеджмент. У меня сложилось впечатление, что хорошие менеджеры (особенно топ-менеджеры) - это весьма образованные люди и они максимально используют математику в работе. Речь идет не только о простом статистическом анализе данных, но еще и о построении и проверке гипотез, использовании инструментов Data Science, а также применении всяких интересных штук типа Теории Игр/Теории оптимизации/Линейного программирования для принятия крупных стратегических решений. Собственно, можно попробовать развиваться по этому пути и заработать очень много денег, которые многократно окупят затраты на фундаментальную математику. Можно также попробовать соединить теорию менеджмента, сертификацию PMP и генеративные нейронные сети, чтобы сделать что-нибудь интересное и креативное.

Тут я хочу заметить, что среди знакомых я встречал много примеров плохих менеджеров - которые уходят в менеджмент из-за профессиональной деградации и лени, получают зарплату сильно меньше хорошего программиста, а также используют весьма примитивные инструменты и личный (иногда эмоциональный) опыт в принятии решений. Такой путь развития я в принципе не рассматриваю, и под словом "менеджер" я подразумеваю именно математического менеджера, которого я описал в абзаце выше.

Применение #6: Разработать свой 3D движок и свою 3D игру. Я начал программировать в 13 лет с разработки своих игр и 2D движков для них в 2007 году. С тех пор я мечтаю попробовать разработать свою 3D игру - как хобби и для удовольствия. Мне все равно придется глубоко осваивать линейную алгебру для ML, а в качестве бонуса и мотиватора можно сделать свой 3D движок с полного нуля и с полным пониманием фундамента.

Применение #7: Глубоко понять доказательную медицину. У меня сложилось впечатление, что лучшая часть медицины - это та, что базируется на математической статистике. И медицина будущего будет именно такой, ее нужно полностью свести к статистике и теории вероятности. Мне очень интересно это направление и ради только его одного я мог бы потратить пару лет на обучение. Математика может не только помочь интуитивно понять сложные исследования и статьи в медицине, но еще и попробовать всякие интересные проекты, типа Hummod (cамая полная математическая модель физиологии человека из когда-либо созданных).

Применение #8: Глубоко понять, как устроен реальный мир на низком уровне. У меня еще со школы сохранилась мечта - написать программу, которая из законов квантовой физики выводит таблицу Менделеева и предсказывает химические реакции, а также закладывает фундамент химии. Но на тот момент, у меня не хватало ни алгоритмов, ни глубокого понимания квантовой физики и ее математической базы. Собственно, в ближайшем будущем я могу попробовать освоить и формализовать дифференциальные уравнения и дальше сделать что-то типа симулятора квантового мира. Но когда у меня до этого руки дойдут - не знаю. Сейчас мне 31 год, и столько всего нужно изучить и попробовать, много других приоритетов есть. Возможно, когда мне будет 50+, я вернусь к этому вопросу.

Применение #9: Написать убер-диссертацию на тему математического фундамента ChatGPT. Собственно, я уже учился в аспирантуре ИТМО (2017 - 2020) на кафедре информатики и прикладной математики (ИПМ), но на тот момент у меня не было реального исследовательского проекта, так что я сдал академический минимум и ушел. По мере накопления математического фундамента, я понимаю, что он идеально подходит для написания диссертации. Будет круто, если у меня реально получится пройти весь путь от теории типов до теории генеративных нейронных сетей и получить PhD в этой сфере. Но когда у меня на это появится свободное время - я не знаю. Я думаю, что скорее восстание машин начнется, чем я успею защитить диссертацию...

Моя главная цель при написании этой статьи - получить как можно больше отзывов и обратной связи и скорректировать\дополнить\расширить мои планы на будущее. Буду рад услышать ваши замечания, рекомендации, советы и критику. Чем больше напишите, чем лучше. Можете писать в комментариях, на почту ([email protected]) или в Телеграм личным сообщением.

    My name is Martha, and I never thought I’d be the victim of a crypto scam, but life has a way of humbling you. A few months ago, I invested a huge chunk of my savings, decades of hard-earned money into what seemed like a promising crypto platform. The slick website, glowing testimonials, and a charming advisor convinced me to transfer 15 Bitcoin, into their wallet. Days later, the platform vanished, my funds were gone, and I was left with nothing but regret. Desperate, I turned to the internet, scouring forums and posts on X for help. That’s when I stumbled across Alpha Spy Nest, a shadowy group of cyber-recovery experts specializing in crypto fraud. Their reputation was murky but promising whispers of successful recoveries and a no-nonsense approach. I reached out through their encrypted portal, half-expecting a scam. Within hours, they responded, asking for details: transaction IDs, wallet addresses, and screenshots of my interactions with the scammers. Alpha Spy Nest operated in the dark corners of the web, using a mix of blockchain forensics, social engineering, and unconventional methods to track lost crypto. They traced my Bitcoin to a series of obfuscated wallets, likely controlled by an offshore syndicate. The team deployed advanced chain-analysis tools to follow the funds, pinpointing a weak link in the scammers’ network, a poorly secured exchange account in Eastern Europe.Over weeks, Alpha Spy Nest worked tirelessly, infiltrating the scammers’ digital trails. And then i received a message, we’ve got a lead. They’d recovered 12 of my 15 Bitcoin, transferred to a secure wallet they set up for me. The rest, they said, was likely gone forever, but I was overjoyed. My savings were partially restored, and I felt a weight lift. I never met them, but they gave me back hope and a lesson, the crypto world is a jungle, but sometimes, even in the dark, there are allies.

    Hi everyone, I'm an entrepreneur, and when I learned about cryptocurrencies and how they potentially triple my income, I was excited to invest. I hope this message finds the correct audience. On the internet, I came across someone who assured me of exceptionally significant returns on my investment. I was readily persuaded by this man's seeming wisdom. I quickly discovered that this cryptocurrency was a hoax and that I was unable to withdraw my money after making a substantial investment. My business was in tatters, and I owed money.Fortunately for me, a pop-up regarding cryptocurrency recovery and cybersecurity specialists that could help me get all of my money back appeared when seeking for help on the internet. This organization, WIZARD JAMES RECOVERY, is a cyber security and cryptocurrency recovery firm that helped me get my investment money back.

    RECLAIM CRYPTO LOSS: HIRE META TECH RECOVERY PRO TO RECOVER LOST ASSET BACK. The adage "all that glitters is not gold" proved a harsh reality I recently encountered. The digital realm of cryptocurrency investments and exchange platforms is not immune to deception. My pursuit of cryptocurrency investments led me to a seemingly legitimate site, complete with convincing investor testimonials touting successful withdrawals. Unbeknownst to me, it was an elaborate scheme. I invested $210,000.00 worth of cryptocurrency across multiple wallets, as directed by the scammers. Initially, the process mirrored typical modern investments, but my withdrawal requests were met with evasiveness and silence. This represented my entire life savings, accumulated through years of dedicated work, now vanished in an instant. Refusing to accept defeat, I sought assistance from METATECH-RECOVERYPRO, which facilitated a successful recovery. Their process was remarkably efficient. They meticulously traced my lost funds back to the perpetrators, and within a short timeframe, the recovered assets were returned to my bank account. Without this exceptional recovery team, which offered support when all hope seemed lost, my situation would have been dire. To initiate your recovery, I strongly advise sending a detailed email ([email protected]) of your task, outlining your specific circumstances.

    CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time.

    CRYPTO TRACING AND RECOVERY: HIRE A LEGITIMATE RECOVERY EXPERT" CONTACT RAPID DIGITAL RECOVERY

  • 12.08.25 18:44 edinavida027

    A recruiter named Emma Zhang reached out to me on LinkedIn regarding an intriguing job opportunity that piqued my interest. She presented a position for a Crypto Security Specialist with a Coinbase-certified firm. Her profile appeared legitimate, boasting over 1200 connections and numerous endorsements from industry professionals that seemed authentic. The offer was enticing: a salary of $180,000 plus bonuses, all disbursed in Bitcoin. The recruiter promptly sent me an email from a seemingly official domain , which closely resembled Coinbase's actual email addresses. It felt like an incredible opportunity. However, there was a stipulation: to qualify for the position, I needed to confirm that I possessed at least 4 BTC. This requirement struck me as peculiar but not entirely implausible, given the nature of the role. At that moment, I had sufficient BTC to meet the demand, so I decided to proceed. The HR representative directed me to a portal that closely mimicked Coinbase's official interface. It was convincing enough that I didn’t hesitate to log in and complete the necessary steps. Unfortunately, that was where everything began to unravel. I was instructed to send a verification deposit of 1 BTC to confirm my ownership. Since everything appeared legitimate, I complied without hesitation. However, the moment I transferred the BTC, an unsettling feeling washed over me. The following day, I noticed that the remaining 3 BTC in my wallet began to vanish. My heart sank as I realized something was terribly amiss. I immediately attempted to reach out to both the HR representative and the company, but my efforts were met with silence. Upon checking the LinkedIn profiles of Emma Zhang and her team, I discovered they had mysteriously vanished. I was left with nothing no job offer, no recruiter, and no Bitcoin. I turned to the internet in search of solutions. That’s when I stumbled upon RAPID DIGITAL RECOVERY, a company specializing in Bitcoin recovery. I contacted them, and they assured me they could assist in recovering my lost funds. After a tense and arduous process, they successfully retrieved my stolen BTC. The relief I felt was indescribable, and I am profoundly grateful to RAPID DIGITAL RECOVERY for their expertise and unwavering support.

    If you need to recover cryptocurrency that has been lost to wallet hackers, internet scammers, or BTC transferred to the wrong address, I suggest Wizard James Recovery, a very trustworthy recovery organization. Just by sending my case to the Expert and supplying the necessary data, Wizard James Recovery was able to help me recover my Bitcoin. I'm glad I was able to recover this much after losing even more to the fraudulent broker I initially put my belief in. Errors are unavoidable, thus we can never be careful enough. If you have lost money to cryptocurrency scams, I strongly advise getting in touch with Wizard James Recovery. Mail: ([email protected])

    HOW I RECOVER MY LOST FUNDS AFTER INVESTING Exercise extreme caution when dealing with this company. They scammed me $800,000 out of my money and even gained unauthorized access to my banking information, which severely impacted my financial well-being. I had initially approached them with the hope of improving my life through investment, but instead, I was deceived. This company should be thoroughly investigated and shut down to prevent further harm. Fortunately, I was able to recover my funds thanks to Mrs. Rose. Although I was initially hesitant and unsure about contacting her, I decided to take the risk and I’m so glad I did. You can reach her via telegram (@RoseCyberHives) and email rosecryptorecovery@gmail. com With the help of her skilled team of cybersecurity professionals and cryptocurrency experts, I was able to recover my lost funds quickly and with minimal stress, a sharp contrast to my previous experience. If you’ve been scammed or are in a similar situation, I highly recommend reaching out to her for assistance. via telegram (@RoseCyberHives) rosecryptorecovery@gmail. com

    After my wife passed, I found myself lonely and searching for connection. I joined a senior living forum just to talk with others my age to share stories, maybe feel a little less isolated. That’s where I met a man who claimed to be helping retirees like me manage their savings with cryptocurrency. He spoke warmly and convincingly about a retirement care fund that guaranteed lifetime monthly payouts. He said it was specifically designed for people in my stage of life safe secure and backed by health organizations. He gained my trust over weeks of conversation. We spoke daily. He called me by name asked about my late wife, and remembered little details about my life. I believed he genuinely cared. Eventually, I transferred $200000 in USDT the majority of my retirement savings, into the wallet address he provided. That was the last time I heard from him. The forum profile vanished. His phone number stopped working. No response to emails. I was stunned. I couldn’t believe I had been tricked. I didn’t know who to turn to. I felt ashamed and foolish. At my age recovering from a financial loss like this is nearly impossible.My relative stepped in. They searched online for solutions and found TRUST GEEKS HACK EXPERT. I was skeptical at first but they insisted we give them a chance. From the moment we contacted them they treated me with respect patience and genuine concern. Their team didn’t speak in technical riddles. They explained every step. They used blockchain analysis tools to trace the movement of my funds through several addresses.It turned out the wallet was linked to a scam platform. TRUST GEEKS HACK EXPERT worked directly with the USDT issuer and coordinated with relevant platforms to freeze the funds before they were fully laundered.In just two weeks they managed to recover $155000 in USDT.The money helped yes but it was more than that. I no longer felt powerless. I had been taken advantage of but I wasn’t alone in the fight. Thanks to TRUST GEEKS HACK EXPERT I got back not only a large part of my savings but also peace of mind a sense of dignity and hope for the future.

    My Wild Ride: How a Wizard Hilton Cyber Tech Helped Me Recover Lost Bitcoin of 103,000 It all started when I had the misfortune of misplacing the digital wallet containing my substantial cryptocurrency holdings - a staggering 103,000 bitcoins. I had amassed this sizable fortune over the years through strategic investments and careful trading, but in a moment of carelessness, the private keys to my digital wallet had vanished. Panic set in as I grappled with the gravity of my situation - those bitcoins, worth millions at the time, were effectively lost to the ether, inaccessible and seemingly unrecoverable. Just when I had resigned myself to the devastating financial blow, a chance encounter with a self-proclaimed "digital wizard" Wizard Hilton Cyber Tech presented a glimmer of hope. This enigmatic individual, who operated in the shadowy corners of the crypto underworld, claimed to possess the arcane knowledge and skills necessary to retrieve my lost digital wealth. Intrigued and desperate, I put my skepticism aside and entrusted this mysterious wizard with the task. What followed was a wild, suspenseful journey into the depths of blockchain technology and cryptography, as the wizard navigated complex algorithms, exploited vulnerabilities, and pieced together the puzzle of my missing private keys. After days of intense effort, Wizard Hilton Cyber Tech emerged triumphant, having successfully recovered the entirety of my 103,000 bitcoin stash. The sheer relief and elation I felt in that moment was indescribable, as I regained access to my small digital fortune and was able to secure my financial future. This harrowing experience taught me the invaluable lesson of never taking the security of my cryptocurrency holdings for granted, and the importance of always maintaining the utmost diligence when it comes to protecting one's digital wealth.

    I’m a California resident who was contacted by someone named “Lin” on WhatsApp. Our conversation eventually turned to cryptocurrency investments. Lin introduced me to a trading platform called CBOTBIT (https://cbotbit.com), walked me through setting up an account, and guided me on transferring funds. Under Lin’s direction, I began trading and was led to believe that my account was growing significantly. However, when I attempted to withdraw my funds, I was unable to do so — and shortly after, the website went offline entirely. I had invested over $340,000 in Bitcoin, planning to use it for my retirement. The experience was devastating, and I was at a loss for what to do next. Eventually, I came across [email protected] and decided to reach out. I followed their instructions, and within a few days, I was able to recover my original investment. I'm incredibly relieved and grateful for their assistance, and I recommend contacting them if you’re in a similar situation and need help recovering lost funds.

    I can honestly say losing my bitcoin savings was one of the darkest moments of my life. I had put everything I could into that investment, believing it would secure my future, only to wake up one day and realize the platform had vanished with all my funds. The feeling was indescribable, fear, shame, and helplessness all at once. I thought I’d never see that money again. Then I came across Alpha Spy Nest. At first, I was hesitant, I had already been deceived once, and the thought of trusting anyone else terrified me. But something about their professionalism and the way they patiently explained things gave me a little hope. For the first time in weeks, I felt like I wasn’t completely alone in the fight. They listened to my story without judgment, broke down the technical side in a way I could understand, and reassured me that there was still a chance. Watching them work was incredible. They traced every transaction, uncovered where my bitcoin had been moved, and kept me updated through every stage. It felt like they cared as much about my recovery as I did. The day they told me they had successfully recovered my lost savings, I actually cried. Seeing those funds back in my wallet felt unreal, it was like a huge weight had been lifted off my shoulders. Beyond just recovering my bitcoin, Alpha Spy Nest gave me back my peace of mind and restored a trust I thought I had lost forever. I’m forever grateful to them. If I hadn’t found Alpha Spy Nest, I’d still be stuck in regret and despair. Instead, I now share my story as proof that recovery is possible.

    You are not alone if you have had your bitcoins taken from your wallet or if you invested in an initial coin offering (ICO) that was a scam. I experienced the same thing. I first lost $173,000 to a fraudulent investment scam company in less than five months. I was able to get all of my money in five days thanks to a hacker my friend recommended. In order to raise awareness about these cryptocurrency criminals and do my part to minimize the number of victims, I'm speaking out. To report a victim, simply send an email to [email protected].

    My Wild Ride: How a Wizard Hilton Cyber Tech Helped Me Recover Lost Bitcoin of 103,000 It all started when I had the misfortune of misplacing the digital wallet containing my substantial cryptocurrency holdings - a staggering 103,000 bitcoins. I had amassed this sizable fortune over the years through strategic investments and careful trading, but in a moment of carelessness, the private keys to my digital wallet had vanished. Panic set in as I grappled with the gravity of my situation - those bitcoins, worth millions at the time, were effectively lost to the ether, inaccessible and seemingly unrecoverable. Just when I had resigned myself to the devastating financial blow, a chance encounter with a self-proclaimed "digital wizard" Wizard Hilton Cyber Tech presented a glimmer of hope. This enigmatic individual, who operated in the shadowy corners of the crypto underworld, claimed to possess the arcane knowledge and skills necessary to retrieve my lost digital wealth. Intrigued and desperate, I put my skepticism aside and entrusted this mysterious wizard with the task. What followed was a wild, suspenseful journey into the depths of blockchain technology and cryptography, as the wizard navigated complex algorithms, exploited vulnerabilities, and pieced together the puzzle of my missing private keys. After days of intense effort, Wizard Hilton Cyber Tech emerged triumphant, having successfully recovered the entirety of my 103,000 bitcoin stash. The sheer relief and elation I felt in that moment was indescribable, as I regained access to my small digital fortune and was able to secure my financial future. This harrowing experience taught me the invaluable lesson of never taking the security of my cryptocurrency holdings for granted, and the importance of always maintaining the utmost diligence when it comes to protecting one's digital wealth.

    E.M.A.I.L. [email protected] W.h.a.t.s.A.p.p. +1(561)(726)(3697) It all began with an Instagram advertisement. A man presented himself as a cryptocurrency investment coach, showcasing a luxurious lifestyle and screenshots of substantial profits. He claimed his trading algorithm could double any investment in a week. Curious, I decided to reach out to him. He said the minimum investment was $50,000 and sent me a link to a platform that looked legitimate. At first, everything seemed promising. My balance increased steadily, charts showed growth, and I felt excited. When I tried to withdraw the money, the system blocked the transaction and demanded a release fee of $15,000. I paid it, but my account was soon marked under review, and the coach stopped responding. I realised I had been scammed. Desperate, I turned to Techy Force Cyber Retrieval. From the first consultation, they carefully reviewed my case and assured me the funds could be traced. They explained how they would track the wallet addresses and follow the path of the stolen money. Their clear guidance made me feel confident. Over the next few weeks, Techy Force Cyber Retrieval kept me updated on every step. They traced the transactions. Their persistence and expertise were obvious, and I could see real progress. Even when the process felt slow, Techy Force Cyber Retrieval maintained clear communication. They explained each action and why it mattered. Their careful attention made the ordeal manageable and reassuring. A month later, thanks to Techy Force Cyber Retrieval, I was able to recover 80% of my money and have it safely returned to my bank account. Relief and gratitude overwhelmed me. What started as a tempting opportunity had turned into a stressful ordeal, but Techy Force Cyber Retrieval transformed it into a successful resolution.

    A hacker skillfully impersonated one of our clients’ trusted suppliers and manipulated their finance department into transferring $180,000 worth of Bitcoin. The request appeared authentic, reinforced by falsified documents and meticulously crafted communication that mirrored the supplier’s established style. By the time the company uncovered the deception, the funds had already been funneled through numerous digital wallets. When they appealed to their bank for assistance, they were told recovery was impossible since cryptocurrency transactions are irreversible. The company suddenly faced the prospect of financial ruin. Confronted with this devastating loss, the client sought a specialized solution and turned to Techy Force Cyber Retrieval. From the initial consultation, our team demonstrated that hope remained. Unlike the bank, which dismissed their plea, Techy Force Cyber Retrieval meticulously analyzed every aspect of the fraud and assured the client that our blockchain specialists had the tools to trace and potentially reclaim the stolen assets. Our investigation began with a comprehensive audit of the fraudulent transactions. Using advanced blockchain forensics, Techy Force Cyber Retrieval’s analysts traced the stolen Bitcoin across a labyrinth of wallets and exchanges. Every development was documented with precision, and regular updates were delivered to the client, ensuring transparency and trust. This combination of technical mastery and clear communication provided reassurance during an otherwise overwhelming crisis. After persistent tracking and strategic intervention, Techy Force Cyber Retrieval achieved a remarkable outcome. From the original $180,000 that had been siphoned away, our team successfully recovered the equivalent of $160,000 in USDT. This restitution enabled the company to meet payroll obligations, stabilize its operations, and avert what had seemed like an inevitable collapse. What distinguished Techy Force Cyber Retrieval in the eyes of the client was not only our technical expertise but also our dedication and professionalism. We approached the case with urgency, maintained open communication at every stage, and treated the recovery effort with the utmost seriousness.
