Einstein's Brilliance

As a part of Windows Vista on my relatively new laptop, came a Google menu bar. I have a calculator on it, a battery meter for the laptop, a digital clock, links to both Wikipedia and Google, and my favorite, "Einstein Quote of the Day". The quotes cover a wide range of topics; but the one showing today, I think encapsulates a wonderful but simple thought.

"If I give a pfennig*, you will be one pfennig richer and I'll be one pfennig poorer. But if I give you an idea, you will have a new idea, but I shall still have it, too."
