Your talk was phenomenal. I’ve been doing this for 37 years. This was at the top. Many students from yesterday’s class came up to me today to let me know that they loved your talk and that you were their favorite speaker this semester. Thanks again for coming to Berkeley and energizing my class the way you did.
