Zephyr is cool. Its installation setup is annoying. But the project is cool.

What they presented on richard Feynman's first seminar in 1941. Does not include quantum mechanics it seems.

As of 2020 (TODO starting when) the Chinese government officially recognizes 55 minorities.

These minorities actually had different legal statuses, e.g. they were exempt from the One Child Policy.

Term invented by Ciro Santilli to refer to problems that can only be solved once we have AGI.

It is somewhat of a flawed analogy to NP-complete.

The Kibble balance is so precise and reproducible that it was responsible for the 2019 redefinition of the Kilogram.

It relies rely on not one, but three macroscopic quantum mechanical effects:How cool is that! As usual, the advantage of those effects is that they are discrete, and have very fixed values that don't depend either:One downside of using some quantum mechanical effects is that you have to cool everything down to 5K. But that's OK, we've got liquid helium!

The operating principle is something along:Then, based on all this, you can determine how much the object weights.
