C. Elegans Reversal, Overwriting That-Which-Should-Not-Be-Overwritten, and Getting the Attention of Dark Gods

Today I Learned:
1) C. elegans fact: C. elegans, the model worm organism, has exactly four sensory neurons dedicated to detecting things-that-make-them-want-to-turn-around. Those four neurons relay their signals to two processing neurons, which integrate that information and, if they decide there's a good reason to turn around, they send a signal to the next layer of neurons, which triggers the worm to immediately reverse direction.

It is always the same four and the same two, in every worm.

2) Python fact: You can overwrite the map function in Python. It is not a good idea. You cannot, however, overwrite "for" nor "lambda".

3) Destiny fact: If you shoot Oryx in the face, he looks at you.
