"Do you know what the most complex mass of protoplasm on earth is?" Marian Diamond asks her students on the first day of anatomy class as she casually opens a flowery hatbox and lifts out a preserved human brain. "This mass only weighs 3 lb., and yet it has the capacity to conceive of a universe a billion light-years across. Isn't that phenomenal?"
Diamond is an esteemed neuroanatomist and one of the most admired professors at the University of California, Berkeley. It would be a privilege for anyone to sit in on her lectures. And, in fact, anyone can.
