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.
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.

حوادث پرتوی💫
☢ هنگام حوادث پرتویی کجا باید برویم؟
☑️ در صورت بروز حادثه پرتوی در منطقهی شما، باید فوری به داخل ساختمان بروید.
🛐 صرفه نظر از مکانی که در آن هستید، اقدام ایمن آن است که:
🔸 به داخل ساختمان بروید، در ساختمان بمانید، گوش به زنگ باشید.
همهی درها و پنجرهها را ببندید
🔹 به زیرزمین یا وسط خانه بروید. مواد رادیو اکتیو روی قسمت بیرونی ساختمان مینشیند؛ پس بهترین کار این است ک…

☢ یکاهای تابش یونساز چه هستند و چه کمیتی را نشان میدهند؟
🔆 تابش یونساز به تابشی گفته میشود که انرژی کافی برای جدا کردن الکترونها از اتمها و مولکولها را دارد. این ویژگی میتواند باعث تغییرات زیستی در سلولها شود، بنابراین اندازهگیری میزان تابش و اثرات آن اهمیت زیادی دارد. یکاهای شناختهشده اندازهگیری تابش یونساز عبارتند از:
🔹 بکرل (Bq) یکای پرتوزایی است و شمار واپاشیهای هستهای در واحد زمان را نشان می…

💢 پیشرفت بزرگ در همجوشی هستهای؛ نزدیک شدن انرژی پاک بیپایان با هوش مصنوعی
☑️ دانشمندان بریتانیایی و اتریشی ابزار هوش مصنوعی جدیدی بنام GyroSwin را توسعه دادهاند که میتواند پلاسمای فوقالعاده داغ داخل راکتور همجوشی را شبیهسازی و محاسبات را در چند ثانیه( بجای چندین روز حتی با وجود ابرکامپیوترها) انجام دهد

Showing the 12 most recent of 20 posts we hold for @NuclearEngineering. 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 — 1,069,721 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 1 registered channel — 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.
Named by
Channels on the register whose posts name this channel's handle.
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.
