Interesting Engineering engagement report
@IntEngineering - 319K followers on X
Measured over 69 original posts from a 30-day window, last computed on October 14, 2026.
Engagement
A typical post picks up 11 interactions against 319K followers, an engagement rate of 0.004%. Measured over 69 original posts, its engagement rate beats 14% of 20,444 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 2.9K times each, and 0.374% of those impressions turn into an interaction. That is about 0.921% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.8 posts a day over the last 30 days, though only 20% of days saw any activity at all. Most posts go out around 00:00 UTC, and Wednesday is the busiest day of the week. Of the 69 posts sampled, 30% carry an image or video and 64% link out. The account's strongest tracked post pulled 53 interactions, about 4.8x its own typical post.

Compared with accounts its own size
Interesting Engineering's engagement rate beats 14% of the tracked X accounts closest to it in follower count (20,444 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 21% 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 0.004%, Interesting Engineering sits below the 10th percentile of the 204,956 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.024%.

Posting timing
This account posts most often around 00:00 UTC, and Wednesday 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 | 30% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 64% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 30% 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.
- 64% 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 327 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.

KIMLAB at the University of Illinois Urbana-Champaign has built Ringbot Quad, a monocycle robot that throws out the usual drivetrain and instead puts four individually powered modules inside a single ring shaped wheel, each one topped with an articulated leg. In driving mode the legs handle balance and steering while the ring rolls along; in walking mode they take the full weight of the body and it moves like a quadruped. The compact prototype comes from Kevin Gim and Joohyung Kim, and the work was presented at ICRA 2026 in Vienna.

Researchers at Peking University have developed an embedded chip cooling system that uses a dielectric fluid called HFE-7100 and a two-phase cooling process, where the coolant absorbs heat as it transitions from liquid to vapor inside microchannels etched directly into the chip substrate. Unlike water-based cooling systems, which risk short circuits due to electrical conductivity, dielectric fluids are electrically insulating. Previous dielectric cooling approaches were limited to below 1,000 W/cm², but the new system achieves a critical heat flux of 1,570 W/cm² through a manifold design with horizontal inlets for liquid replenishment and vertical outlets for rapid vapor evacuation. The system was fabricated using standard semiconductor manufacturing techniques, making it compatible with existing chip production processes. The research is published in Nature Electronics.

Researchers at KTH Royal Institute of Technology in Sweden and the University of Southampton have developed a flat ribbon-shaped optical fiber called HARFF (High Aspect Ratio Flat Fiber) that achieves up to 1,000 times greater pressure sensitivity than conventional cylindrical optical fibers. The flat geometry — with aspect ratios approaching 20:1 — allows the fiber to deform far more responsively to transverse forces and hydrostatic pressure than a round fiber, changing its optical properties in ways that can be precisely measured. Two air channels running through the fiber create deliberate asymmetric deformation under pressure, altering a property called birefringence that shifts the light pattern traveling through it. A separate version with a tin-based alloy filling one channel demonstrated enhanced temperature sensing, exploiting the mismatch in thermal expansion between metal and glass. The team has already drawn more than 120 meters of HARFF from a single experimental preform, demonstrating manufacturability at scale. Potential applications include structural health monitoring in composite aircraft wings, drones, bridges, batteries, and industrial equipment — anywhere early detection of strain, pressure, or temperature changes is critical. "This is not just a different looking fiber, it is a new design space for optical fiber," said KTH researcher Pawel Maniewski. The research remains at proof-of-concept stage. 📷 Pawel Maniewski / Nature Communications

Taiwan's XING Mobility has launched IMMERSIO CTP, a marine battery system in which every cell is fully submerged in a dielectric coolant instead of being cooled from the outside. The company says the design suppresses thermal runaway and stops fire spreading between cells, which lets it pack cells tighter for up to twice the energy density of a conventional marine battery. It is already running on the Porrima P111 in Taiwan and on an Austrian vessel called Smart IQ.

A typical post picks up 11 interactions against 319K followers, an engagement rate of 0.004%. Measured over 69 original posts, its engagement rate beats 14% of 20,444 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 2.9K times each, and 0.374% of those impressions turn into an interaction. That is about 0.921% of the follower count, which is the gap between an audience on paper and an audience in a timeline.

- What is Interesting Engineering's engagement rate on X?
- Interesting Engineering (@IntEngineering) has an engagement rate of 0.004%, based on the median interactions across 69 original posts from the last 30 days against 319,034 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.004%, Interesting Engineering sits below the 10th percentile of the 204,956 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 @IntEngineering have real engagement?
- Its engagement rate beats 14% of the tracked X accounts closest to it in follower count (20,444 accounts), which puts it in the bottom quarter for its size 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 @IntEngineering post?
- Most posts go out around 00:00 UTC, and Wednesday is its busiest day, at roughly 2.77 posts per day across the measured window.
