I took 114a and 191c with doc Langdon. He is the best professor at ucla. He is dynamic and interesting and makes every class tell a story. I only wish I had discovered him earlier so I could have taken his classes every semester. There is for sure work involved but it's interesting and relatively simple if you make a basic effort. I love him and I just wish more professors at ucla were as involved and interesting as he is. What other professor tries to learn people's names in a class of 100? Doc you are a gem... You reignited my interest in school in general!
