“I had some wonderful teachers in high school, including a chemistry teacher who really got me started,” he says. “One day I asked her, ‘Why are egg yolks yellow?’ She said, ‘why don’t you find out?'” So he did. He still remembers the answer : the sulfur compounds in chicken feed become concentrated in the yolk, turning it yellow. “I also had an excellent physics teacher,” he says, describing why he became an atmospheric physicist.
