The function f(x)=1/x is continuous, but its graph is not connected. It's an interesting one to explain to people.

Again, I never said that psychologists could prescribe medication. I only talked about psychiatrists. I think I may have misread the parent post. > ("Sectioned". We don't use committed over here. OK

There are psychologists today who think that higher IQ is a cause of greater wealth and success. I wasn't referring to the original incarnation of IQ theory, which was designed to identify children who needed more attention from their

In the UK, they can encourage you to take certain kinds of medication. I've seen them get quite pushy with this. They can't force you unless you get committed.

I just derived the spherical law of cosines that's the foundation of this formula using quaternions and Sympy. The quaternions were modelled as 4x4 matrices. The philosophy is that you can treat trigonometry as a triangle construction

The advantage of calorie-counting is that it's quite easy - especially when you use something like My Fitness Pal. That doesn't mean it's correct, of course. What alternative is this article advocating?

Apologies, I guess I overreacted. I do that sometimes.

There is no web link. It's a pay wall. Did you not get that? [edit] I was able to read it using the Tor Browser. There's a quota on the number of articles before it activates the pay wall.

The eigenvalues of a 2d rotation matrix are complex numbers. There's no point in trying to visualise the corresponding eigenvectors. You'll need 4 dimensions for that. (The 4 dimensions come from the fact that the eigenvectors of

I don't have a suitable workload with me right now. Has anyone tested the performance of PyPy3 vs PyPy2? Last time I tested it on a problem, PyPy2 was significantly faster (at least x3). That was maybe one or two years ago, when it was

It could be material while not being expressible by a Turing machine. If by "algorithm" you mean something that runs on a Turing machine, then human intelligence doesn't have to follow any algorithm. If you mean that human in

When I said "Bauhaus"ed, I'm referring to the simpler shapes and lack of ornamentation, like a piece of modern architecture. I'm not claiming they took any direct influence from Bauhaus. But on that note... The "Met

Fair enough. They may be cheaper short-term. But I'm noticing from the flat roofs that they might not be so long-lasting (how likely are they to cave in from snow or rain?). So they might not be cheaper long-term. But I guess they migh

It seems that the Bauhaus were trying to make a political point as much as an engineering point. Also, where's the evidence that the simpler geometric forms and use of cheap materials (concrete in Brutalism) resulted in anything cheape

Regarding modern architecture, I'm not a fan. It's not like a painting which you can hang up on your wall at your own leisure. No, these are buildings that people have to live in and around. I think London is worse off with the

Steganography is a way to defend against rubber-hose cryptanalysis. See "Security": https://xkcd.com/538/ Maybe in the future people will be using something like Rubberhose FS.
