How an Archimedes screw works to move material

⚙️ Engineering

In Shanghai, 432 robots moved an entire residential area weighing 7,500 tons to lay a subway

The houses were moved for more than two weeks: every day the mechanical workers took 10 synchronized steps. When the construction was finished, the buildings were put back in place.

While we live in 2025, the Chinese live in 2077.

Walmart in the U.S. is officially rolling out drone delivery — couriers are gradually becoming unnecessary. Even now, drones are already delivering groceries straight to people’s homes, like salt-and-pepper pistachios, changing the delivery market and speeding up the process of receiving orders.

⚙️ Engineering

A guy took a 1966 Mustang, ripped out all the internals, and swapped in the guts of a Tesla Model 3 — leaving only the body and part of the retro interior.

Now, under the classic hood, there’s an electric motor and the full Tesla functionality: autopilot, summon-from-parking via the app, modern driver assists, and the complete set of Model 3 features.

The Dzhanibekov Effect, clearly demonstrated

The Dzhanibekov Effect is a strange and fascinating phenomenon that occurs when an object rotates around one of its axes in microgravity.

If you spin a nut in space, it can suddenly flip over and start rotating in a different direction. This happens because the object’s moments of inertia differ along its three axes, creating instability in its motion.

The effect was first demonstrated in orbit by cosmonaut Vladimir Dzhanibekov in 1985.

💥Sodium metal and water

Metallic sodium is one of the most active elements in the periodic table, and during contact with water it releases a large amount of energy in a short period of time, which causes it to ignite and, most often, explode.

🌬 The air yoke

Small magnets keep the top attached to the base, so that air flow will cause the air to spin as the air passes through the engineered turbine blades of the elegant spiral design.

🕯The Curie point heat engine

The Curie point, or Curie temperature, is the temperature of the phase transition of kind II, associated with a jump change in the symmetry properties of matter (for example, magnetic - in ferromagnets, electrical - in ferroelectrics, crystallochemical - in ordered alloys).

🕯Diffraction spectrum candle

A thin plastic diffraction grating surrounds the flame in this rainbow design. The rainbow spectrum isn't created by refraction, as with a prism, but by diffraction, where light waves deconstructively and structurally interfere.

This CEO laid off nearly 80% of his staff because they refused to adopt AI fast enough. 2 years later, he says he’d do it again

All those who do not immediately learn to integrate AI into their work processes will lose their jobs.

🔪 Hydroabrasive cutting

⚙️ Engineering

18 months after becoming the first human implanted with Elon Musk’s brain chip, Neuralink ‘Participant 1’ Noland Arbaugh says his whole life has changed.

"I see how the advancements in tech at this point are going to solve so many things. They are, I think, the future of medicine. I think a lot of disabilities, cures, and answers that we’ve been searching for a long time will come through tech—and that kind of surprised me."

It’s nuts that the device holds so well for such a long time.
