4 measurements spanning 7 days, net -13. 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 8,940–8,957 and does not start at zero.

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.

ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate.

Readings taken12 Aug 2026, 15:45 UTC

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.

Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.

Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

Reaction mix

696 reactions across 18 posts, in 13 distinct kinds. The most used accounts for 56.9% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.

Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.

Coverage. Reactions were read on 18 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 696reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 20 most recent posts we hold, published 8 March 2026 to 20 July 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

YPhB — Youth Physics Battles Встречайте один из турниров IYSB — International Young Scientist Battles! Youth Physics Battles — это командные физические бои, где важно не только решить задачу, но и уметь грамотно её представить, выстроить стратегию и ответить на вопросы оппонентов. На YPhB ценятся командная работа и умение аргументировать свою позицию. Две лиги: — Младшая: 7–9 классы — Старшая: 10–11(12) классы Лиг

Замечательный физик, преподаватель и энтузиаст Леша Свинцицкий затеял важное дело: летний бесплатный миникурс по математическим методам в физике: https://t.me/atrium_phys/281 Цель курса — помочь школьнику преодолеть пропасть между теми вещами, которые он прошел в школе по математике, и тем, что ему уже пора уметь делать в физике: векторы, производные, интегралы, дифференциальные уравнения. Так что велкам!

26 июня в 11 часов (Мск) будет проведен второй (и последний) вебинар, посвященный экстремальным задачам. Тема занятия — Минимаксные задачи в тригонометрии. Вот листок с задачами для вебинара. Занятие будет очень насыщенным и наверняка продлится больше обычных 120 минут. Материал по минимаксной тригонометрии огромен, и мне хотелось бы многое вам рассказать.

Это первый вебинар мини-курса Экстремальная тригонометрия; вот листок с задачами для вебинара Мы разберем пару задач ДВИ (для второй — особенно непростой — вспомним трюк с расщеплением слагаемых), а также рассмотрим несколько минимаксных задач (с Росатома, ОММО, ПВГ, ВМК), в которых используется неравенство Коши.

Минимаксные задачи 23 июня в 11 часов (по Москве) состоится четвертый (заключительный) вебинар мини-курса по экстремальным задачам в алгебре: Минимаксные задачи. Это чрезвычайно популярная тема, неизменно присутствующая на олимпиадах и ДВИ. Речь идет о нестандартных уравнениях и неравенствах, которые зачастую имеют настолько «жутковатый» вид, что при первом взгляде на задачу не очень понятно, что тут вообще делать.

Наша цель — продемонстрировать мощный инструмент взлома задач ДВИ и различных олимпиад (в дополнение к неравенству Коши, которое было темой предыдущего занятия). Вот листок с задачами для вебинара.

Showing the 12 most recent of 20 posts we hold for @telemathus. 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 — 106,770 of 1,169,250entries 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.

Forward network

Republished by

Channels on the register that have forwarded this channel's posts into their own feed.

Republishes

Channels on the register whose posts this channel has forwarded.

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 6 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.

Names

Channels on the register whose handles appear in this channel's posts.

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.
