Let’s Read the Internet! Week 3

Self Control and the Prefrontal Cortex John Lehrer at The Frontal Cortex

Summarizes some research that indicates people only have a certain amount of willpower to ration out over the day. My first reaction to reading this article was to think, “yeah, but that’s only for weak people, not me.” My next reaction was to resist the temptation to check my email too frequently. My third reaction was to slaughter eight cats in a murderous frenzy, then to sit forlornly surveying the carnage I had wrought and wonder if this cycle would ever end.

Scott Belcastro’s Lonely Searching from Erratic Phenomena

I’ll admit I don’t know much about art, but I can tell when something looks cool. I saw how similar the paintings were, and felt surprised at first that people don’t get bored doing the same sort of thing over and over.

The Laplace-Runge-Lenz Vector Blake Stacey at Science After the Sunclipse

A clever way to prove that orbits in a r^{-2} potential are conic sections, without solving a complicated differential equation. I’m surprised we didn’t do this in ph1a, although I’m kind of glad we didn’t, because it makes me appreciate it much more now.
