## My Math Blog

Welcome to my blog. My plan is to write about math topics that interest me and, hopefully, interest you as well.

It takes a few weeks to develop each topic. The process is a bit like creating an app. Every few days you add a new feature but most days you just polish the existing features. So make sure you come back often to see what's new.

If you would like to leave a comment, ask a question, or suggest a new topic, please send me an email.

Here is the topic I'm working on right now:

Relativity
Why does time slow down for Bob when his rocket
travels close to the speed of light?

... and here are all the topics so far:

The Pinball Machine and Pascal's Triangle
How many paths take the pinball to the second cup?

The Travelling Salesman Problem
In what order should you visit 20 cities to minimize the distance travelled?

Simulated Annealing and the TSP
