Yeah, that's not what that means. In math "dimension" is used as a statistic. As in, "this manifold has a dimension of 4". So you can say things like "in dimension 4" to mean "when the dimension is

It's common in math to say things like "in dimension 2" to mean "when the dimension is 2". It doesn't necessarily refer to a specific space (although it could based on context). It's just setting a conte

I'm not sure what you mean here. This is discussing a 1-dimensional structure embeded in 4-dimensional space. If you're not sure it works for something else, well, that isn't what's under discussion. If you just mean y

I think that argument cuts the other way on this one. If there were some higher-rank person, presumably a noble, ordering a volley, as depicted in TV shows, and as happened with firearms, there would be a bias towards mentioning that per

Why did you replace "quadratic" with "exponential"? Quadratic isn't exponential.

How is any law to be enforced? Most actions governed by law don't take place via such a visible and formal mechanism, and yet laws are written about them anyway! (Also, when I spoke of a "reason to think it might be illegal"

No? It seems to be quite common. What's your reason to think that it might be illegal?

So, to summarize, the original typewriter layout (1868) was alphabetical, with the top row (A-N) going left-to-right and the bottom row (O-Z) going right-to-left. Then (1870), the vowels (including Y) were pulled out and put in a separate

No. What they actually do is that they do a regression with both X and Z among the independent variables, and then look solely at the coefficients coming from X. (As mentioned in the article.) Including Z as a dependent variable alongsi

How? Quarks can't change into leptons. Charged leptons can't change directly into other charged leptons. And neither charged leptons nor hadrons are going to pass through such a quantity of matter, as you say. I mean I assume

Octonions and so on up are indeed a thing, but I don't think they do what you want. Even aside from the fact that they're restricted to power-of-2 dimensions, their algebraic properties get worse as you iterate the Cayley-Dickson

That's not an argument, that's a restatement of the problem; that's what being irrational means. The problem is to prove that you can't create sqrt(2) with a fraction. How, exactly, would this statement have been obv
