If You Missed Comet Ison

November 23, 2013

If you tried catching the recent comet Ison in the night sky, it is too late. I is now in the sun’s glare. But, there will be a second chance after it swings around the sun in November 28. You will be able to see it in a more convenient time, after sunset, I think. Before you had to get up really early to see it before the sun rises. Anyways, keep checking astronomy news and the charts. Also, check if the comet survives the trip around the sun, as it goes really close to the sun, and there is a possibility it might break up. If you do see it eventually, though, enjoy!

Minimizing Quantity Part 4: Euler-Lagrange Equation

November 23, 2013

In the last three posts, I talked about paths that minimize time. In all those cases, it involves objects going through a path and minimizing certain quantities. But is there a single equation that covers all physical situations that involve finding the path that minimizes quantity? The answer is yes, and it is called the Euler Lagrange equation.

If you know calculus and the gamma function, you might as well use it to try and learn to get the volume of an n-sphere:

Super Mario Bros. Analyzed

I recently found a pretty cool list of articles that analyzes the game design of the original Mario bros. I remember that I never got further than 6-3. Stupid old games and their lack of save points!
