Karl has been creating Great Moments in Science® for many years now. They celebrate all sides of science; from sublime moments of deep thought to the most arcane and bizarre research imaginable. The universe is a strange and wonderful place and, in his Great Moments, Karl has scaled the highest peaks as well as turned over the pebbles to see what's underneath.
