Conservation of Lack of Energy

I'm really short on energy, thanks to this muscle strain thingy. I grab for a couple of hours of sleep, courtesy of Icy Hot (but only once or twice a day), or for an hour or so of rest (tucked into the right-hand corner of my couch, one of the few places of minimal pain); I eat a bit, or drink a bit more (water, milk, OJ. coffee, tea, cocoa). Once in a while I have the energy to post something for my classes.

Today, I put up something on the Bernoulli brothers (took longer than I expected, straightening out their work on the brachistochrone problem); I've mapped out a post on Nicolaus and Daniel, focusing on the work on the fringes of mathematical expectation (a concept in statistics).

For my other history of math clase, I've mapped out a couple of posts on the solution of cubic and quartic equations - one on the people, with some discussion of Renaissance Italian politics and economics, and one on the methods: how they solved those equations, the problematic aspects of their techniques, the first evidence of the necessity of complex numbers even for the solution of real problems, and why their techniques, though quite ingenious, were ultimately a dead end.

And in differential geometry, the stretch drive: the concept of parallel transport, which leads to geodesics, which finally leads to the brilliant and beautiful Local and Global Gauss-Bonnet Theorems.

I think I can, I think I can...
