Has anyone taken any of these free classes? I signed up for Think again: How to Reason and Argue from Duke University and Imagining Other Earths from Princeton.
They are free courses that are offered through various institutions. School is expensive and learning is important so why not make them free! Coursera offers classes through various places for free.
I'ma learn how to argue about space. :colbert:
Has anyone ever done these? What was your experience? Free knowledge, yay or nay?
