(I just added this to my "about" page.) I have been remiss in not mentioning my wife on this “about” page. You see, I really and truly couldn’t be doing this without her. She supports me completely. She supported me when I quit my “real” teaching job to start a company with an amazing vision and no profits. Even though she has never taken a physics class in her life, she watches every minute of every video and gives constructive criticism. She provides a wonderful sounding board and knows how to tell me one of my ideas is terrible without putting me down. We met when I was 16 and we are still in love today. Kate, thank you so much for all your help.
