A serious scientist and a pop culture figure would seem to make any person interesting enough. But Tyson has hobbies and interests that go well beyond the mysteries of space and the sharing of science. He and his wife, Alice - who he met in a physics class - are both foodies. Tyson has said they probably spend too much money on food, but living in Manhattan they have so many restaurants to explore and so many food options to try out they take every opportunity they can to enjoy new foods. Tyson is a also wine connoisseur. His love of science plays a big role in his enjoyment of wine, helping him to understand why different wines taste different and how they can be best served. Like much else, Tyson explains these concepts simply so that non-scientists can understand them, too. "The lower-than-32-degrees freezing point of liquids that contain alcohol, like wine, allows you to chill a bottle of white wine to sub-freezing temperatures without it freezing, before you bring it a dinner party. The wine warms up during the travel time to just the right temperature in time for dinner." And a rather well-known scientist is the source of Tyson's favorite quote about food and wine ... Galileo. "The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do."

Food, wine, physics ... what's left for him to care about and learn about? Calligraphy, for one. Tyson can create beautiful lettered art with a feather pen, but is especially passionate about fountain pens. He loves them so much that his wife spent 6,000 dollars to buy him a Japanese-made pen as a gift when he finalized the contract for his autobiography. He even gave an entire interview to the New York Times on the pen and his love of calligraphy. In the interview, he described his own mathematical theory behind how you can tell if a pen is perfect for calligraphy. Having to dip the pen to refresh the ink after 6 to 8 words mean you're writing with a beautiful rhythm, he says.

He's passionate about life and the finer things in it. He's passionate about science, and the world knows it. With all that he's accomplished in his life and the celebrity status he's achieved, it would be easy to excuse Tyson for having a large ego. But he doesn't. In fact, he takes special pains to point out the danger of ego: "If your ego starts out, 'I am important, I am big, I am special,' you're in for some disappointments when you look around at what we've discovered about the universe. No, you're not big. No, you're not. You're small in time and in space. And you have this frail vessel called the human body that's limited on Earth." Perhaps this attitude is a large part of his success and why he is so beloved. For all his intelligence and his contributions to the study of space, Neil DeGrasse Tyson remains firmly planted with two feet on Earth.
