Physics In History engagement report
@PhysInHistory - 1.1M followers on X
Measured over 93 original posts from a 30-day window, last computed on September 1, 2026.
Engagement
A typical post picks up 575 interactions against 1.1M followers, an engagement rate of 0.052%. Measured over 93 original posts, its engagement rate beats 62% of 3,791 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 36K times each, and 1.59% of those impressions turn into an interaction. That is about 3.28% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.2 posts a day over the last 30 days, with activity on roughly 57% of days. Most posts go out around 09:00 UTC, and Sunday is the busiest day of the week. Of the 93 posts sampled, 95% carry an image or video. The account's strongest tracked post pulled 24K interactions, about 42x its own typical post.

Compared with accounts its own size
Physics In History's engagement rate beats 62% of the tracked X accounts closest to it in follower count (3,791 accounts, accounts of similar size (decile 9 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 64% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

At 0.052%, Physics In History sits above the 25th percentile of the 36,654 accounts in this comparison. That places it in the below the median band, which runs 0.012% to 0.08%.

This ruler is the whole measured catalog, not a size-matched group: it shows where the raw rate falls across every account we can measure, all of which are large. For a like-for-like comparison, read the size-band percentile above instead. See how the bands are built
Posting timing
This account posts most often around 09:00 UTC, and Sunday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it. -- A. Einstein (1879-1955) https://t.co/9FrTZ0SaUe

Actress Hedy Lamarr was far more than a Hollywood star. She was also a brilliant inventor. During WWII, she and composer George Antheil devised a frequency-hopping radio system to prevent enemy forces from jamming torpedo signals. Their 1942 patent introduced an idea that later became fundamental to spread-spectrum communication, helping pave the way for technologies such as Wi-Fi and Bluetooth.

Dirac was 31 when he shared the 1933 Nobel Prize in Physics with Schrödinger, making him the youngest theoretical physicist to win the prize at that time. He initially considered declining it because he disliked publicity, until Ernest Rutherford pointed out that refusing would generate even more publicity.

Albert Einstein and Kurt Gödel became close colleagues at Princeton, often walking home together from the Institute for Advanced Study. Gödel used Einstein’s general relativity to discover a bizarre rotating-universe solution in which the equations allowed paths through spacetime that could, in principle, return to your own past. Einstein was fascinated by Gödel’s result, and reportedly joked that he came to work mainly so he could have the privilege of walking home with Gödel. 📷 IAS/Princeton

Measured over 93 original posts, its engagement rate beats 62% of 3,791 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 36K times each, and 1.59% of those impressions turn into an interaction. That is about 3.28% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.2 posts a day over the last 30 days, with activity on roughly 57% of days. Most posts go out around 09:00 UTC, and Sunday is the busiest day of the week. Of the 93 posts sampled, 95% carry an image or video. The account's strongest tracked post pulled 24K interactions, about 42x its own typical post.
- What is Physics In History's engagement rate on X?
- Physics In History (@PhysInHistory) has an engagement rate of 0.052%, based on the median interactions across 93 original posts from the last 30 days against 1,101,827 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.052%, Physics In History sits above the 25th percentile of the 36,654 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @PhysInHistory have real engagement?
- Its engagement rate beats 62% of the tracked X accounts closest to it in follower count (3,791 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @PhysInHistory post?
- Most posts go out around 09:00 UTC, and Sunday is its busiest day, at roughly 3.2 posts per day across the measured window.
