b = np.ones(1)
c = np.ones(1)
c = c/(2**73)
b += c
>>> ufunc 'add' output (typecode 'O') could not be coerced to provided output parameter (typecode 'd') according to the casting rule ''same_kind''
but `b = b + c` does work.[1] https://stackoverflow.com/questions/12588986/typeerror-gener...
I think most people who study this would say the common denominator is that metals lack a band gap and have a very mobile sea of electrons, and therefore good conductivity. Metals can be amorphous, or crystalline, or anywhere along the spectrum.
The "new school" certainly hasn't forgotten, or ignored, that crystals are patterns that tile all of space. These are known as space groups, and they enumerate every way to tile 3D space symmetrically (https://en.wikipedia.org/wiki/Space_group).
Anyways, I can guarantee that people who really study the subject absolutely take courses in metallurgy, crystallography, 3D math, and much more.
Also, if you're interested in simulations, I don't do that much myself, but you can always run some open source simulation software. http://www.opencalphad.com/
Besides it being exceedingly difficult to find someone to talk to about this, when I finally did in the chat service they offer, as soon as I brought up my account they terminated the chat with some copy/paste message about how they cannot talk to me about it as it might compromise their fraud detection. People I've talked to have mentioned that it might be due to the fact that there was "Flesh" in the title, but that is a valid description of the good I was trying to sell.
I guess what I'm trying to say, is that it felt entirely arbitrary, I had no recourse with regards to the discussion, and eBay is similarly shitty with regards to service.
