Actually a good point, tho. And also a good thought: If there is no special direction, what would be up? And that's where quantum mechanics gets even weirder: It's either up or down in the direction you measure.

But they don't use Bluetooth.

Pretty sure the blade is untreated, you shouldn't even wash it with soap.

The technical term you're looking for is "almost all" prime numbers. Not joking btw.

Small nitpick: Mandarin is the name of the spoken language. The written language you are talking about is called simplified Chinese, as opposed to traditional Chinese used in Taiwan (who also speak Mandarin).

I had to derive osmotic pressure for my statistical mechanics exam in my bachelor's. So in what sense don't we know?

Thank you for the explanation!

Could someone explain how paying a person not to publicly talk about what you did is illegal? If a company does this, it's called NDA. Is it because prostitution is illegal in the US?

At least cosmology does use some serious quantum physics, even quantum field theory. Source: took 1 year of theoretical cosmology lectures.

They weren't talking about radioactive decay, electrons are stable. They were talking about electrically charged particles emitting electromagnetic radiation when accelerated. (Circular movement is accelerated, see centripetal force) Since they use energy for this, they would very quickly fall into the nucleus (if I remember correctly, in around 10^-14 s).

Bodies with mass also emit gravitational waves when accelerated, but much less.
