a thought -- mathematics is certainly derived from some parts of philosophy at some level. but the foundations of math - proof theory, model theory, and so forth - are equally part of theoretical computer science. looks like inserting computer science into the purity ordering might be tricky after a...

the box isn't a part of the universe -- the box is the universe, and the electrons are the particles in this universe, with no other particles around, so there isn't a sense in which it's isolated since it's the only thing there. so, in a universe of this type, it makes sense, and more to the point,...

because you can't have two electrons in a box, because then you would know where the electrons are, meaning you don't know how fast they are moving, meaning they are out of the box. this is just incorrect. I did not say the box has zero width or anything silly like that. I also don't see why I can'...

well yeah, exactly. all the rest of the sciences depend on the universe. similarly, if you could change carbon backbone to silicon backbone or something, all the sciences from biology on would be affected, while physics and math would not. each layer requires a corresponding increase in dependence.
