MIT on Tumblr theme of the week: MIT professors being awesome.
This means reciting medieval poetry, swinging across the classroom on a pendulum, etc. - all to infuse the passion of their subject into their students. If you feature an MIT professor being awesome on your Tumblr, use the hashtag #onlyatmit. Who knows, we might reblog you!
