Now who's to say that's not just some 3d studio max artwork made by some scientist who's bullshitting you about what's really going on?

That was a pretty neat video. Nice link Kracus.

Maybe he is referring to the diffraction patters generated during X-ray cyrtallography. I got to work in a crystallography lab for a few months way back when. Interesting stuff, expensive machines. I remember the good old days of SGI workstations. But getting proteins to crystallize can be a real pain in the ass.

And werldheld tell me about Fourier transformations and crystallography.

Oops, didn't see the link - but I am too lazy to watch it at the moment.

I got a beaming machine.

Kracus wrote:Oh no I'm sure he needed that cleared up.

Anyway yeah I didn't know the name of the machine but the pics still don't look anything like that first one he posted. It's kinda neat though isn't it?

Yeah, it was neat when IBM wrote their logo with it about 10 year ago.

Why do want me to tell you about them? Do you miss testing your students?
All I know about crystallography is basic stuff you learn in any chem class: you know, x-rays refracted off of molecules, using the pattern to determine molecule structure, Rosalind Franklin, Watson & Crick, etc. Kracus' description made me think of those patterns, too, which is why I mentioned it, but I think I've seen STM images that look more like what he was talking about.

I have no idea what Fourier transformations are -- never even heard of them.

I believe he's referring to Fourier transforms. http://mathworld.wolfram.com/FourierTransform.html

Basically you can use them to examine a signal and extract its frequency components.

That sounds like math and phyisics. *hides in the corner*

So is that the sort of thing that's used to process radio signals?

All sorts of signal processing applications, yes.
