As I remember it, when the partial pressure of O2 drops below that found at an equivalent altitude of 14,000 ft you start to get hypoxic. You can train your way up to higher altitude tolerance, as mountain climbers do, but I think there is a fairly hard limit of around .16 or .14 atm ppO2 in...

Your characteristic function there would appear, in a 2 dimensional vector space, where x, runs horizontally, and y runs vertically, as a diagonal line from the lower left, to the upper right--i.e. a plot of x=y. We're looking at the characteristic function as another variable, z, then really...

oh yes, I forgot to mention, thankyou very much, that just transformed my whole take on vector spaces. -Mark

You guys are SO cool!

While reading wikipedia I found the following quote: "...When this basis is indexed by a discrete (finite or countable) set, the vector representation is just the column of numbers familiar to high-school students. Vector bases may also be continuously indexed. When a quantum mechanical state...

I'm looking for advice about which physical/mathematical model to study in order to understand the mechanism of cooper pairing of electrons in super conductivity. As I understand it, this requires a description of spin, and the mechanics of wavefunction interaction between two particles...

Can you tell me what mathematical model you would use to represent cooper pairing in superconductors? I.e. you need a model of spin, and you need a model of spin pairing. What physical model/lie group configuration can explain this? Does it need to be relativistic? -Mark

The fermionic condensate is acheived the same way as it would be with a bosonic condensate. By supercooling the material to within a fraction of a degree above absolute zero. Techniques used to do this include a form of stimulated immissions involving lasers operating at resonant frequencies...
