I would've laughed, too...

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.
