Who is the smartest person you know?

And I mean book smarts intelligence, not street smart or wisdom wise.

Four examples from my own life.
-A buddy of mine from college is currently a candidate for a Nobel Prize in Physics. He does research up at I believe Michigan State now, he not so subtly suggested to me a few years ago that he may be working on some kind of invisibility thing.
-I used to be friends with a girl in college, Laura, and worked with another girl as a camp counselor, Betsy…. Today they are both brain surgeons.
-My cousin Mikey is a genius. No other way to put it. He taught himself Russian and computer coding languages in middle school. He went to the University of Michigan for some kind of financial degree, and had amassed several hundred thousand dollars on the stock market before graduating. He turned down a job with a New York financial firm because his wife is still in grad school at UM, and the firm said “Oh no that’s fine, we’ll pay you to work from home and we’ll just fly you out when we need you in person.” He now makes, at age 25, more than the rest of my extended family combined.

What about you, who’s the smartest person/people you know.
