This question in Ghasham's tajme3at most might haven't been familiar with, but it's related with the thermal expansion of objects, which is a very simple idea with simple rules. Thermal expansion is defined as the change in length or volume of any material when temperature changes. The two types of thermal expansions are: 1- Linear thermal expansion: ΔL = α L₀ ΔT • ΔL is the change in length [meter (m)] • α is the c…

20 posts held, back to 21 December 2025 — 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 20 posts for this entry, the most recent from 12 May 2026. An engagement rate over an empty window would be a number about nothing.

These are the 6 cases you should know in order to solve questions on them and draw conclusions Only the fourth case (from top) is stated in zamabook and is used to solve this compound microscope question Optics: Light Ch 6: Convex "Lenses"- 6 cases Note 1: First 5 cases are the same as Concave "Mirrors". The difference is in the "6th case" (this correlation makes it easier to remember them) Case A: 1st (from top)-…

Showing the 12 most recent of 20 posts we hold for @SAATlessons. 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 — 962,000 of 1,160,990entries 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.
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.
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.
