About

Hello my name is Michael. I’ve always had this curiosity of wanting to understand how things innately came about. When I heard that mathematics had a lot to do with where we are today as a civilization, I was drawn to it and perplexed. “How is it possible that math can get us to the point we are now?” I began to read about the history of mathematics from the time of Pythagoras to Newton. I began to do more mathematics. The more I did math the more curious I got. I wanted to know where the formulas came from; I wanted to get an intuitive understanding of how it all worked. Ultimately I wanted to know, “What is mathematics?” And that’s why I got my degree in math. I’m still going through my journey of discovering more, but I also like sharing what I’ve learned. I’ve made these animated videos while I was in college to inspire others to understand math. I am currently in my third year of teaching Algebra 2. FAQ: "What software do you use?" I use adobe flash, maya and imovie
