Which maths are the most useful for killing people?
Haha, no. You can't do anything meaningful with geometry without "screwing with numbers" anyway.
Who are you to decide what is "meaningful" and what isn't?
the more maths you do, the less numbers appear. We only really see 0, 1, 2, i, e and pi on a regular basis. And infinity.
aforementioned maths puzzle:
What fraction of this regular octagon is shaded?
over nine thousaaaaandths!
But I like it.
I forget the definition, I thought it was 1/ln(2). It turns up a fair bit. Why do you like it?
over nine thousaaaaandths!
Gamma function sucks anyway. Why is Gamma(z) = (z-1)!
It should be called z!
That's a bound, not a value.
Gluing a bunch of dodecahedra sounds like an assload of difficult work compared to figuring out a couple of rates.But in geometry, you can actually see what you're doing. If you want to prove that dodecahedra cannot tesselate space, and you don't want to screw around with numbers, you can just glue a bunch of dodecahedra together. That's over nine thousand times better than trying to calculate when two trains will collide.
You obviously never got high with a bunch of D&D nerds in a craft shop. That was probably the only time when pipe cleaners have actually been used for cleaning pipes...
