Quanta Magazine engagement report
@QuantaMagazine - 368K followers on X
Measured over 70 original posts from a 30-day window, last computed on October 4, 2026.
Engagement
A typical post picks up 117 interactions against 368K followers, an engagement rate of 0.032%. Measured over 70 original posts, its engagement rate beats 51% of 20,444 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 12K times each, and 0.98% of those impressions turn into an interaction. That is about 3.24% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.5 posts a day over the last 30 days, with activity on roughly 60% of days. Most posts go out around 20:00 UTC, and Friday is the busiest day of the week. Of the 70 posts sampled, 44% carry an image or video and 100% link out. The account's strongest tracked post pulled 1.1K interactions, about 9.7x its own typical post.

Compared with accounts its own size
Quanta Magazine's engagement rate beats 51% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 10 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 47% 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.
Where this sits in the catalog
At 0.032%, Quanta Magazine sits above the 25th percentile of the 205,048 accounts in this comparison. That places it in the below the median band, which runs 0.024% to 0.143%.

Posting timing
This account posts most often around 20:00 UTC, and Friday 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.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 44% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 100% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 44% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 100% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 300 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

When a crystal is placed near a magnet, its electrons can only have certain amounts of energy. When this phenomenon is graphed, fractal patterns called Cantor sets emerge. https://t.co/eZRP500zLx https://t.co/PfrkNi3GzN

This morning, mathematicians at OpenAI announced that a group of 10,000 autonomous AI agents under their direction proved that the Navier-Stokes equations can “blow up,” thus solving one of the six remaining Millennium Prize Problems. But this massive result is not without controversy. https://t.co/I0f1hwvETo

John von Neumann, a 23-year-old prodigy, was the first to recognize and define the quantum world as a Hilbert space. Once he did, exploring the ins and outs of Hilbert space would lead physicists to a deeper, more unified understanding of quantum physics. https://t.co/lUMqdRj69S https://t.co/YJmHMYQNGO

In the 1990s, physicist Leonard Susskind proposed that black holes are literally holograms, that everything happening inside can be observed from the outside. “I thought it was a little bit crazy,” Susskind said, “but I thought it was the least crazy of all the possibilities.” https://t.co/XgsJ4yvzbM

Entropy — a term commonly thought of as a measure of disorder — is now known to change depending on the observer. Anthony Aguirre has defined a quantity he calls observational entropy that other researchers say helps to clarify ambiguity around this phenomenon. https://t.co/65yqxATyar

In 1870, the Norwegian mathematician Marius Sophus Lie was in France when the Franco-Prussian War broke out. His geometry notes were mistaken for encoded German messages, and he was arrested, accused of being a spy. Today, his work on group symmetries has revolutionized math and physics. https://t.co/xzS35CapVH

Hyperbolic surfaces are impossible to imagine, but aspects of their geometry are still mathematically accessible. To study these mysterious shapes, mathematicians measure how connected they are. Here’s what that means: https://t.co/5OfOYZvTYQ https://t.co/4V28PbLgGv

Reading these numbers
A typical post picks up 117 interactions against 368K followers, an engagement rate of 0.032%. Measured over 70 original posts, its engagement rate beats 51% of 20,444 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 12K times each, and 0.98% of those impressions turn into an interaction.

- What is Quanta Magazine's engagement rate on X?
- Quanta Magazine (@QuantaMagazine) has an engagement rate of 0.032%, based on the median interactions across 70 original posts from the last 30 days against 368,277 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.032%, Quanta Magazine sits above the 25th percentile of the 205,048 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 @QuantaMagazine have real engagement?
- Its engagement rate beats 51% of the tracked X accounts closest to it in follower count (20,444 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 @QuantaMagazine post?
- Most posts go out around 20:00 UTC, and Friday is its busiest day, at roughly 2.47 posts per day across the measured window.
