This scenario actually happened in a planetary science class at University of Arizona today. My daughter's roommate Bonnie was the victim.
My professor says, "Everyone remembers the escape velocity of the Earth from when they were a kid, right?" I thought she was joking and I laughed. Out loud. Everyone else nodded and she says, "Of course, it's 11.2 km per second."
I don't think I had the same childhood that these people did...
Well, Bonnie... I would've been nodding, too... but only because I would've been nodding off. Unless, of course, she were really referring to how many seconds it would've taken me to escape that class. Or her. Or plantary sciences in general.
I think Bonnie and I had the same childhood.
