Welcome to my laboratory. This is where I teach people everything I know about mathematics and computation. I am slowly building up my own platform for human reasoning, which I affectionately call Espresso. I hope that I can change the way you think about human reasoning, no matter the subject. I also want to help you connect the seemingly exclusive concepts of mathematics you've learned throughout your schooling. I will do this by providing source code, interactive demonstrations, exercises, links to free online resources, and material to supplement those resources. The cost is $2.95 per month.
