Estimating Pi using Monte Carlo Simulation

This video briefly shows how you can use pseudo random number generation to estimate pi.

A while back on G+ Sarah Del Valle posted a link to an article with 12 "quirky" problems: http://goo.gl/GY4eP. One of those describes the process in this video using "throwing darts at a dart board analogy", someone suggested using "rain drops" as an analogy to get away from the non randomness of throwing darts.

The github repo with the code can be found here: http://goo.gl/wvsAK

Here's another video which shows a different type of simulation (Discrete Event Simulation: which is used to model queues):    • Simulating a Queue: Basic Discrete Ev...
