America, 1946. The Wurlitzer 1015, nicknamed the Bubbler, had tubes of colored liquid light and held 24 records. One nickel bought three plays in diners and bars across the country. More than 56,000 were built, and it is still the jukebox people picture when they hear the word.

まじかぁ！こっちのGitHubで作った3Dモデルもヤバいことになってきている！
どんどん映像表現が広がっていくわ！

I don’t know what motivated whoever it was that posted nasty false things about a single mom with a generosity, kindness and integrity beyond words. Whoever is doing it, please stop. That is a source of great frustration.
I am not accusing or threatening anyone but responding to the extremely hostile menacing tone which typifies some accounts which have been said by others to be connected to accounts performing what looks like harassment and doxing. I am taking this matter to law authorities immediately.

Why is energy conserved? Why does angular momentum stay constant?
In 1918, mathematician Emmy Noether showed that these aren’t separate coincidences. They’re tied to symmetry. If the laws of physics don’t change with time, energy is conserved. If they don’t change with rotation, angular momentum is conserved.
Nature’s conservation laws have symmetry at their root.

An F1 engine can't simply be started with a key like a normal road car. Its components are engineered with extremely tight clearances, so temperature plays a critical role in getting everything ready to run.
Before starting, the team circulates pre-heated oil and coolant through the engine for roughly 20 minutes. This warms the internal components and fluids, helping the engine reach the conditions it needs for a safe startup.
Once everything is at the correct temperature, the engine can finally be fired up. It's a perfect example of how much precision goes into an F1 power unit, where even starting the engine requires careful preparation.

This isn't really the big problem. The bigger problem is it's immoral to claim something is true when a human has not checked it, especially when AIs take shortcuts and are designed to keep people using them
In our latest video, we speak with Terence Tao, one of the world’s top mathematicians and author of Six Maths Essentials, to diagnose the state of the field of mathematics right now and explore if it has a future even in the face of increasing automation. Watch now: youtu.be/EYrlyxuyFbs

If f = −ν∆u, then in the forced NS:
∂ₜu + (u·∇)u − ν∆u + ∇p = −ν∆u -- Then they cancel.
We knew this for a hundred years. Why is @OpenAI acting like this is a solution? We KNEW THIS SINCE THE PROBLEM WAS CONCEIVED.

The US Air Force puts its first hypersonic weapon into production.
The Air Force awarded Lockheed Martin a $694 million contract to build and field the AGM-183A Air-Launched Rapid Response Weapon (ARRW).

An airplane just landed at a heliport. In lower Manhattan. That is the @ElectraAero EL-2, the ultra-short takeoff and landing prototype aircraft. CEO Marc Allen said Monday it was the first time the manufacturer has shown the EL2’s capabilities publicly in such an environment.
