Just so that the dual of L

^{p}would be L

^{1-p}(for 0<p<1)? Or is there some other reason why this notation is better?

With regards to temperature, I'll point out that differences in temperature come up a fair bit in physics. One example is the differential equation for an object coming to thermal equilibrium with its environment:

dT/dt=-l(T-T

_{0})

(l is some constant measuring how much thermal contact there is between the object and the environment).

If we make the change of variables B=1/T, these differences get troublesome to deal with. For instance, we get the rather ugly differential equation:

dB/dt=l(B-B

^{2}/B

_{0})

so I think inverting temperatures would cause more difficulties than they solve. Sure, negative temperatures being hotter than any positive temperature is weird, but really, how often does one encounter, in physics, a negative temperature?
