Выкладываем запись лекции главного редактора журнала «Квантик» Дориченко Сергея Александровича «Об укладке блинов, котлет и апельсинов», которую он прочитал 26 октября для Лектория Малого мехмата.
На лекции разобраны несколько этюдов из комбинаторной геометрии. Например, вы узнаете, почему на круглую сковороду, где поместилось 6 одинаковых круглых котлет, влезет и 7 таких котлет, а если в куб поместилось 3 одинаковых апельсина, то поместится и 4.

The channel appears to be part of the broader information war that has developed following Russia's invasion of Ukraine. The Kremlin has paid Russian TikTok influencers to push propaganda, according to a Vice News investigation, while ProPublica found that fake Russian fact check videos had been viewed over a million times on Telegram. To that end, when files are actively downloading, a new icon now appears in the Search bar that users can tap to view and manage downloads, pause and resume all downloads or just individual items, and select one to increase its priority or view it in a chat. Just days after Russia invaded Ukraine, Durov wrote that Telegram was "increasingly becoming a source of unverified information," and he worried about the app being used to "incite ethnic hatred."
