Physics Today engagement report
@PhysicsToday - 1.0M followers on X
Measured over 2 original posts from a 30-day window, last computed on September 1, 2026.
Engagement
Early reading. We have captured 2 original posts for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 52 interactions against 1.0M followers, an engagement rate of 0.005%. Posts are seen about 17K times each, and 0.301% of those impressions turn into an interaction. That is about 1.74% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.07 posts a day over the last 30 days, though only 7% of days saw any activity at all. Most posts go out around 16:00 UTC, and Thursday is the busiest day of the week. Of the 2 posts sampled, 100% link out. The account's strongest tracked post pulled 99 interactions, about 1.9x its own typical post. Recurring topics include #histstm, #nasaroman. Only 2 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Posting timing
This account posts most often around 16:00 UTC, and Thursday 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.

Gravity is unique among the known fundamental forces: There is currently no experimental result that requires a quantum theory of gravity. Markus Aspelmeyer and @four_form explore what’s needed to identify elusive signatures and finally connect gravity to quantum mechanics. https://t.co/R1i6mAWybN

Researchers don’t need to do science engagement alone. As Jessa Barder writes, working with professionals makes the job easier, more effective, and can lead to better science. https://t.co/enLk2r9Fa8

US and Soviet (later Russian) scientists helped end the Cold War nuclear arms race in the 1980s and 1990s. Three prominent individuals involved in the disarmament efforts—Frank von Hippel, Roald Sagdeev, and Thomas Cochran—give a firsthand account of those successes. #histSTM #nuclear #disarmament https://t.co/nkCUidb5GS

Mathematician @KenOno691 took a leave of absence from @UVA to join the AI startup @axiommathai, which helps build tools for verifying math proofs. He says that researchers can use AI to serve different roles, like those of the librarian, math teacher, and discovery partner. #ai #math https://t.co/4C75nLSuNj

Last month, the Niels Bohr Library & Archives at @AIP_HQ made public three interviews with J. Robert Oppenheimer that were formerly only accessible to a select few researchers. Ryan Dahn analyzes the context of one of them: a 1963 interview that focused on Oppenheimer’s early career in Europe and California. #histSTM https://t.co/NIzkPOf899

Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.
Recurring topics
The most frequent hashtags in the sampled posts. They describe what this account writes about; they are not a performance signal, and the catalog-wide breakdown on the hub shows how little hashtag count moves.

Reading these numbers
A typical post picks up 52 interactions against 1.0M followers, an engagement rate of 0.005%. Posts are seen about 17K times each, and 0.301% of those impressions turn into an interaction. That is about 1.74% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.07 posts a day over the last 30 days, though only 7% of days saw any activity at all. Most posts go out around 16:00 UTC, and Thursday is the busiest day of the week. Of the 2 posts sampled, 100% link out. The account's strongest tracked post pulled 99 interactions, about 1.9x its own typical post. Recurring topics include #histstm, #nasaroman. Only 2 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.
- What is Physics Today's engagement rate on X?
- Physics Today (@PhysicsToday) has an engagement rate of 0.005%, based on the median interactions across 2 original posts from the last 30 days against 1,003,992 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.005%, Physics Today sits above the 10th percentile of the 36,521 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 @PhysicsToday have real engagement?
- There is not yet enough sample to rank this account against others of its size.
- When does @PhysicsToday post?
- Most posts go out around 16:00 UTC, and Thursday is its busiest day, at roughly 0.07 posts per day across the measured window.
