Quanta Magazine engagement report
@QuantaMagazine - 366K followers on X
Measured over 40 original posts from a 30-day window, last computed on September 2, 2026.
Engagement
A typical post picks up 144 interactions against 366K followers, an engagement rate of 0.039%. Measured over 40 original posts, its engagement rate beats 47% of 6,874 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 1.18% of those impressions turn into an interaction. That is about 3.31% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.3 post a day over the last 30 days, though only 27% of days saw any activity at all. Most posts go out around 20:00 UTC, and Tuesday is the busiest day of the week. Of the 40 posts sampled, 33% carry an image or video and 100% link out. The account's strongest tracked post pulled 1.1K interactions, about 7.8x its own typical post.

Compared with accounts its own size
Quanta Magazine's engagement rate beats 47% of the tracked X accounts closest to it in follower count (6,874 accounts, accounts of similar size (decile 8 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 52% 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 0.039%, Quanta Magazine sits above the 25th percentile of the 66,128 accounts in this comparison. That places it in the below the median band, which runs 0.016% to 0.1%.

Posting timing
This account posts most often around 20:00 UTC, and Tuesday 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 | 33% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 100% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 33% 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 248 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
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

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 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

In the 1920s, two distinct forms of quantum mechanics developed back-to-back: Werner Heisenberg’s “matrix mechanics” and Erwin Schrödinger’s “wave mechanics,” two radically different incarnations of one theory. But what was the theory? It was this question that fascinated mathematician David Hilbert, and later, his protégé John von Neumann. https://t.co/gtfngQGtE4

Quantum mechanics was developed 100 years ago. Today, it's helping to build the machines of the future, like nuclear clocks and quantum computers, which derive their power from the ability of quantum objects to sustain multiple simultaneous possibilities. https://t.co/HKlGPhQru2

Reading these numbers
A typical post picks up 144 interactions against 366K followers, an engagement rate of 0.039%. Measured over 40 original posts, its engagement rate beats 47% of 6,874 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 1.18% of those impressions turn into an interaction. That is about 3.31% of the follower count, which is the gap between an audience on paper and an audience in a timeline.

- What is Quanta Magazine's engagement rate on X?
- Quanta Magazine (@QuantaMagazine) has an engagement rate of 0.039%, based on the median interactions across 40 original posts from the last 30 days against 366,268 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.039%, Quanta Magazine sits above the 25th percentile of the 66,128 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 47% of the tracked X accounts closest to it in follower count (6,874 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 Tuesday is its busiest day, at roughly 1.33 posts per day across the measured window.
