It steam engines when it's steam engine time, and I guess it theory-of-relativities when it's theory-of-relativity time.

It's still pretty remarkable that Einstein/Shannon were the ones to discover their respective theories though. Can you imagine what it must have been like for them? I've always envied genius. Genius always know exactly what it's supposed to do and just does. Recently I'm wondering whether I'm truly cut out for my chosen field (programming).
