This post from Pharyngula is soooooooo true.
The four classes that were indispensable for my success as a graduate student and scientist are:
Conversational Spanish: The Culture, Art, and Religions of South America
American Politics: Writing for the Masses
The History and Philosophy of Neuroscience
Writing, public speaking, debating, divergent thinking....these are skills that you must have to move on to higher education and beyond.
