Astronomer Geoffrey Marcy is famous for discovering planets. He’s a planet finder! I was enjoying this fine article about him, when I came to this:
When the astronomers realized in 2012 that they would need more time than planned for their survey, Dr. Marcy put on his “lucky underwear” … and went to NASA headquarters to argue for more time.
So one of the greatest scientists of our time wears "lucky underwear"?! *applause*
