Good day Professor Devlin,I found you through your Stamford online math class. After watching two of your utube videos I am convinced you will go down in history as the most extraordinary mathematicians in this century. You are improving the world, and you certainly changed my perspective on math, which has always been full of fear. I look forward to learning eveything I can from you for as long as I live.. I am deeply humbled and grateful to you. Blessings and eternal thanks!
