The history of our world has been greatly influenced by its mathematicians. They have developed the code and strategies and understanding that has allowed trade, agriculture, industry, management, engineering and science to develop. In this part of my website, I would like to draw your attention to some amazing men and women from all periods who can inspire and intrigue you. They are presented in no particular order.

I enjoyed your presentation and no it wasn’t too long. Each subtraction algorithm has its merit as you demostrated, but after learning the “one up and one down” method, I’m employing it because of its speed and ease of usage. Even my wife, who hates mathematics with a passion, thinks it’s too easy. I look forward to your future presentations on both multiplication and number theory. I read an introduction text book some twenty five years ago on number theory by Oystein Ore who taught at Yale for better than twenty years. So in closing, please produce these lectures and the longer the better. Thanks.
