Growth

2 measurements spanning 2 days. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 63–65 and does not start at zero.

Engagement

19 posts held, back to 17 July 2024 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 pageof Telegram’s post history, 20 posts per page.

Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 19 posts for this entry, the most recent from 20 October 2024. An engagement rate over an empty window would be a number about nothing.

Lifetime counters from Telegram’s own channel header, read 10 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.

Давид Бродский написал хорошие посты про инверсию. Всем рекомендую. Пост 1, Пост 2. А ну да в комментариях написали еще уровни. Но я бы сказал, что есть только еще один уровень. Он заключается в том, что инверсия является изогональным сопряжением относительно некоторого треугольника. Треугольник немного необычный правда. Две вершины у него комплексные... Но зато это позволяет расширить инверсию на комплексные точки, …

Это ШОК, товарищи!! Один из наших преданных камрадов поделился экзаменом на совместную магистратуру ШАД и УрФУ. Вообще достаточное условие для обучения: поступить в магистратуру и в ШАД, но те абитуриенты, которые не попали в ШАД, но показали высокие результаты на вступительных испытаниях в магистратуру, получают возможность учиться на траектории «Анализ данных» в течение первого семестра. По итогам семестра принимае…

Путь из точки А в точку В Пару месяцев назад редакция журнала Тинькофф—образование взяла у меня интервью. В нем я ответил на много вопросов: почему я стал учителем, зачем написал учебник, какие задачи интересны детям, что делаю в свободное от работы время, какие математические модели можно потрогать руками, нужна ли история науки в школе, работает ли сейчас социальный лифт в образовании. Это интервью вышло пару дней…

Добрый вечер, камрады! Сегодня решаем задачку с экзамена в ШАД. По силам она будет 10класснику олимпиаднику. Пишите Ваши решения в комментарии! Подсказка 1: выпишите первые члены этой последовательности Подсказка 2: какие числа похожи на последовательность 2, 4, 7, 11 и тп Подсказка 3: подумайте о треугольных числах

Ну что ж, товарищи. Пришла пора решать интересные задачки. Поскольку их давно не было, сегодня разминочное функциональное уравнение из собеса в ШАД. Задачка по зубам даже 8-класснику(который разбирается в пределах) Ждём Ваши решения в комментариях! Подсказка1: подумайте над тем, как часто такое бывает. Нет ли чего-то необычного в условии? Подсказка 2: сделайте удобную замену 2x+1=t, а затем дело за малым - а име…

Showing the 12 most recent of 19 posts we hold for @upstairs_problems. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

Citation-graph rank

Citation-graph rank — 1,435,267 of 1,481,502entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.

Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.

Mentions

Named by 2 registered channels — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.

A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
