Chrobin,

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

Chrobin,

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

Chrobin,

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?

Chrobin,

Thank you for the explanation!

Chrobin,

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

Chrobin,

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.

Chrobin,

Well, as a German, I wouldn’t agree. Generally, nouns describing men are masculine and nouns describing women are feminine. “Das Mädchen” is just an odd one out because it’s the diminutive (always neuter in German) of “die Maid”, which in turn is feminine.

Yes, this doesn’t really apply to objects, but it mostly does for people.

Chrobin,

Well, you’re arguing terminology. But the original commenter’s point was about the association of grammatical gender with gender, and that is definitely a thing in German.

Der Arzt (Male doctor) -> die Ärztin (female doctor) is an example where the grammatical gender changes with the gender of the person, and that’s almost always the case.

Chrobin,

I know. But generally, the gender of the noun describing a person correlates with the gender of the person described strongly.

Chrobin,

No, their point is about people thinking all people of a group have a characteristic because some of them do.

Chrobin,

Populism is basically about simple solutions for complicated problems, and blaming every problem on a certain group of people.

From the right, the most prominent example is immigrants, while from the left, it’s mostly rich people.

Chrobin,

Gravity isn’t a force tho…

Chrobin,

Well, firstly, we can quantize gravity pretty easily, it just has unphysical divergences.

But secondly, I think it makes most sense to talk about the current accepted physics because we don’t know how quantum gravity will work.

Chrobin,

In our current understanding of physics, it’s an effect from the curvature of space and not a force. Quantizing gravity results in unphysical divergences. Whether there will be a way to model gravity as an exchange of particles, we can’t know for sure. So according to our current knowledge, it’s not a force.

Chrobin,

But the point of general relativity is that a free-floating observer is equivalent to an observer in free space. That means that falling due to gravity, which you call a force, is an unaccelerated movement, i.e. no force.

Chrobin,

I’m not trying to argue approximations. Physics is just approximations all the way down. But as a physicist, I also love arguing about technicalities, and that’s also kinda the point of science communities for me.

Chrobin,

That’s why I differentiate between publicly traded and privately owned companies. In the former, if the CEO’s ethics are stopping profits, they get kicked out. In the latter, if the CEO/owner happens to be a nice guy, it can have an impact on the company as a whole.

Chrobin,

Many people are trying to give a definitive answer, and there are good theories, but honestly, it is still very much an open question. There are multiple interpretations and as people tend to do in popular science, some spread their opinion as a fact, but we don’t have one correct answer.

Chrobin,

For that, you need Hilbert spaces, linear operators on them, a little spectral theory, …

Chrobin,

That is actually not backed by science. Mixing material is a lot more effective than focusing on one thing.

Chrobin,

The only thing I quickly found is this paper, which says that learning multiple things is not better nor worse than one thing at a time, but it also states in the abstract that cognitive psychologists believed up to that point that mixing multiple topics is beneficial.

Chrobin,

Everyone always says how great and optimized etc the game is, but for me, I had glitches every few minutes with crashes every few hours. Maybe the multiplayer is worse, but how I experienced the game, it was far from being ready to ship.
