They’re testing a function where it quickly skips to a point most people skip to effectively skipping sponsors. At least I got that experiment.

That’s not really correct. While yes, ads don’t pay great, this is generally the case, and maintaining servers with these amounts of data is really expensive. And with YouTube premium, actually, YouTubers get paid quite well. You can take a look at the LTT finances video. They make more money from premium than from YouTube ads, even though only a small fraction has it.

Judging by the name RungeKutta62, named after a class of numerical integration methods and thus two mathematicians, I’d say they’re a nerd themselves.

In German, we have “Wenn Fliegen hinter Fliegen fliegen, fliegen Fliegen Fliegen nach”. Notice that all nouns are capitalized in German.

Every other year the EU tries to pass another mass surveillance law - and the EU court of human rights rules it illegal.

Just to add some formality to this, the original commenter might want to look up the shell theorem for classical mechanics and Birkhoff’s theorem for general relativity.

Yeah, quantum mechanics lingo: measurement = interaction

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.

The technical term you’re looking for is “almost all” prime numbers. Not joking btw.

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.

Pretty sure a court told them to.

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.

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.

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.

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.

Gravity isn’t a force tho…

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.

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

I think you just have to differentiate whether you want to do mathematically rigorous QM (which gets arbitrarily hard), or just do useful calculations.
