Galton Board App

This app simulates a Galton board, which is a pegboard that you drop marbles through and they bounce off the pegs and fall into bins. It shows a natural appearance of the famous Bell curve from statistics, and addresses a whole bunch of other math stuff like triangular numbers and Pascal’s triangle in a natural and interesting way. Beautifully done, could be a wonderful teacher’s aid or homeschool resource.

This app has many levels. To fully ‘get it’ one has to know quant finance, some distributions theory ( Binomial and Gaussian) and Efficient Markets. The golden bead is what Active investors should simulate and see where they land. That will convert them to index investing. As an aside by tilting your mobile device you can skew the distribution. Fun! The team that must have coded it also did a great job. A must have for quants or even Dads showing their kids that math 🧮 can be fun!

Using this app, I was able to better understand the use of the bell curve. This helped me to study for my exams to make sure i can fully grasp this idea. The app is very easy and simple to use. It is clear and direct to make sure you fully understand. I like how the math equations for why this statistic works is added on the side too incase that interests you as well, or if you just want to know why! Overall, definitely an app I would recommend whether it be for educational use or just for fun.
