gil degrasse tyson is here. many know him as the most powerful nerd in the universe. he calls himself simply a servant of science. he is the host of a new talk show on the national geographic channel called start talk. it combines science, culture, and comedy to help bring the universe down to earth. i'm pleased to have him back at this table. when did you know that what you wanted to do was be an astrophysicist? at age nine, a first visit to the hayden planetarium. it put something in my veins. i think it was the universe that called me and not that i called it. of course, growing up in the bronx, there are not many stars visible anywhere in new york, especially not the bronx at the time. so this guy at the planetarium was magical to me. i did not think it was real. i thought it was a hope. thed seen this guy from bronx, and this was not it. therefore it must be a hoax, not knowing of course that it is for training the real guy. toage 11, i had the answer that annoying question that adults ask children. what do you want to be when you grow up? an astrophysicist. that
