Just because you can do something, does that mean you can teach it? Ever had a professor who you knew was brilliant, but was nevertheless feebly inarticulate when it came to helping you understand why the Cauchy-Schwarz inequality was so freaking important?
Doing is one skill, and teaching is another, and the intersection of the two is disappointingly rare.
Happily, my friend Alan Kennedy, who has written here before about his adventures in the music industry, is talented at both doing and explaining. He’s here this week to talk about his fascinating new window on the world. He generally steers clear of the Cauchy-Schwarz inequality, but you just might learn something useful about Jennifer Aniston.
