Happy Pi(e) Day!


This recipe is worth revisiting every year. This year I’m using all organic universe so I hope it turns out okay.
Also included: A lovely video classic from Vi Hart on why pi is wrong (sort of) as she makes the case for tau, with pie. Yummy math. I’ll take my transcendental irrational constants with a side of ice cream, please.

It is important for scientists to be aware of what our discoveries mean, socially and politically. It’s a noble goal that science should be apolitical, acultural, and asocial, but it can’t be, because it’s done by people who are all those things.

fuckyeahfluiddynamics:

Great ski jumpers are masters of aerodynamics. There are four main parts to a jump: the in-run, take-off, flight, and landing. An athlete’s aerodynamics are most vital in the in-run and, naturally, the flight. During the in-run, the athlete is trying to gain as much speed as possible, so she tucks down and pulls her arms behind her back to streamline her body and keep her frontal area as small as possible. This limits her drag so that she can maximize her speed at take-off. Once in the air, though, the jumpers act like gliders. In flight, there are three forces acting on the the jumper: gravity, lift, and drag. Gravity pulls the jumper down, and drag tends to push her backwards up the hill, but lift, by counteracting gravity, helps keep jumpers aloft for a greater distance. To maximize lift, a jumper angles her skis outward in a V and holds her arms out from her sides. This configuration turns the jumper’s body and skis into a wing. The best jumpers will tweak their positions with training jumps and wind tunnel time to maximize their lift while minimizing their drag in flight and on the in-run. Technique is critical in ski jumping, but conditions play a significant role as well. Tomorrow’s post will discuss why and how judges account for changing conditions. (Photo credits: L.
