A thought for a Sunday

"People get the wrong idea. If you're a scientist the two most exciting things you can be are wrong or confused, because that means there's a lot left to learn, and we are living in very exciting times.

In a single human lifetime our picture of the universe has changed so much it's not surprising that we are continually surprised".


Lawrence M. Krauss (b. 1954)
