Yeah, but now think more like a physicist (I actually have little idea
how to do that):
We need snapshots of those 2^200 electrons from the point of the big
bang to the present in picoseconds. And then there are the "what-ifs"...
Not to mention their x,y,z position and various qualities like energy
level and spin...
You laugh? too bad, no?
