Authenticity is, and will only increasingly become, the 'thing' required to communicate and cut through the noise of the AI era. Human mistakes, short-hand, and obscure language reference are the new anti-AI human detection mechanisms.

We finally figured out why 2,000-year-old Roman concrete survives in seawater while our modern concrete crumbles in decades. The Romans used "hot mixing" with lime clasts. When the concrete cracks and rainwater seeps in, it dissolves the lime, recrystallizes it into the cracks, and literally heals itself. We need to start building like this again.

For everyone's reference/information on how stupidly expensive these scanners are, even in 2026:

The Treventus ScanRobot 2.0 MDS costs approximately $97,000 for the core system, based on the most recent public contract award I found:
- a March 10, 2026 contract for one ScanRobot 2.0 MDS was awarded at €84,470, equivalent to about $96,900 at the current EUR/USD exchange rate.

Treventus does not publish a standard list price; sales are quote-based. The standard system includes the scanner, ScanGate RT capture/processing software, workstation, high-end monitor, and keyboard.

The upper range is consistent with a recent World Bank procurement plan that allocated $150,000 for a ScanRobot 2.0 MDS and related add-ons, although the amount was an estimated procurement budget rather than the final purchase price.

When you move your hand through space, you aren't just moving a mass along a smooth path; you are broadcasting a complex, multi-layered signal across the physical fields of the universe.
The macroscopic shape and motion of your hand serve as the envelope, while the underlying thermal, electromagnetic, and spacetime fields act as the medium that absorbs, scrambles, and carries that complex information outward forever.

This laser can't escape the water. Physics won't let it.

It's called total internal reflection and it's the same physics behind fiber optic cables.

Star Axis is complete. Fifty years in the making, land artist Charles Ross has finished his monumental observatory on a mesa in New Mexico. A staircase, aligned with Earth's axis, climbs to a open lens that tracks Polaris and the 26,000-year cycle of Earth's gravitational wobble.

Joe Rogan was stunned after hearing about the hidden structures beneath Angkor Wat.

Cassie Coppersmith: In 2012… that’s a great photo, Jamie.

Joe Rogan: Oh…

Cassie Coppersmith: In 2012, they did a LiDAR survey in Cambodia, and what they discovered completely shocked the world. You can see Angkor Wat right in the middle of that giant moat. There were huge mound fields all around Angkor Wat, both inside the moat and outside of it.

Cassie Coppersmith: If you go south of it, you can see these giant spiral embankments. Just zoom out a tiny bit, Jamie. Do you see those spirals in the bottom left side of the screen?

Joe Rogan: Mm-hmm.

Cassie Coppersmith: Those are a mile long from one side to the other. These are the geometric features at Angkor Wat.

Joe Rogan: And these are hidden from the naked eye?

Cassie Coppersmith: Yes. They’re under the jungle canopy. Nobody knew they were there until 2012, when the LiDAR results came out.

Joe Rogan: Holy shit.

Cassie Coppersmith: There are mound fields that are a mile long. This particular mound field is a mile long. It’s a 10-by-10 mound field, and these mounds are enormous. They’re about 30 feet across, and there’s no explanation at all for what they are.

The ocean has hidden sound highways. This paper turns WOA23 temperature/salinity into a public global map of 13 undersea acoustic parameters, including the deep sound channel, whose median axis sits ~950 m down. Open data for sonar, comms & ocean science!

Vision is a loop, not a glance.

We introduce ActiveVision, a benchmark testing whether models can repeatedly observe, reason, and seek new visual evidence.

Humans solve 96.1%. The best frontier model: 10.6%. Fable 5—strong at reasoning and coding—scores just 3.5%.

The human body is the nanotechnology factory. To progress onward one must constantly look inward.

@bcherny where is the actual paper?

@DrHughT I can say with 100% certainty that there is no second sphinx, and that @Filippobiondi_1 is an individual who seems to only care about money and fame. @DrHughT and @BrightInsight6 you both should realize that and stop wasting your time with a modern day charlatan.

@MKBHD It does not look like a genuine, un-manipulated photo. It looks edited, composited, or synthetically generated.

Other structural considerations for engine placement include the fact that aft-mounting or above-wing engines require reinforcement. This is easily resolve by one or more of the following solutions:

- Carbon-fiber composite fuselage strengthening for engine pylon support.
- Active vibration control systems to reduce flutter effects.
- Titanium-reinforced nacelle mounts to handle thermal and aerodynamic loads.

The circulating image from the X plane had me wanting to research other X planes that we may not know of or have heard of yet. Below is a thread on the one I have found most interesting, and what I would do to make it even better:

To meet high efficiency and noise reduction goals, the ultra-high-bypass (UHB) geared turbofan is the best choice:
