The Topological Problem with Voting

We like to think that plurality voting is "fair", but it turns out that some unexpected paradoxes appear when you analyze it mathematically. In this video, we use topology and the Möbius strip to explain Chichilnisky's impossibility theorem, and we revisit the Möbius strip synthesizer. Become a Pa...

Три видео о звукоинженерии по касательной к абстрактной алгебре. Человек обрабатывает звук и буквально ПОВОРАЧИВАЕТ СПЕКТРОГРАММЫ 🤯, это можно видеть в первом видео:

https://www.youtube.com/watch?v=OHXNnsjLjQI

Во втором видео автор осваивает повороты спектрограммы на 90 градусов и показывает, что это действительно группа вращений квадратов - четыре поворота возвращают нас в изначальное состояние:

https://www.youtube.com/watch?v=ApLHV24nj7I

Поворот на 90 градусов - это перестановка осей времени и частоты. Частота становится временем, время становится частотой.

Это означает, что мы можем повернуть кусок звука, обработать его, повернуть обратно и получить интересные результаты. Это исследуется в третьем видео:
