Today I Learned: 1) ...the "true" definition of molecular cooperativity. Cooperativity is (can be?) defined as a property of a chemical reaction in which one reaction makes a second more likely. 2) ...a few bits and pieces of Norse mythology. There are a surprising number of giant worms (snakes) in Norse myths. Also a lot of wolves, ravens, and eagles. All three of the latter were in some sense signs of war -- not good things. Wolves, for instance, didn't have their modern connotation of nobility. They were considered savage, bestial things, full of hunger and spite. 3) You can, in principle, build a high-gain, high-accuracy amplifier from a high-gain, low-accuracy amplifier coupled to a low-gain, high-accuracy amplifier.
