The Two Cultures
Tom Chivers is particularly scathing of Rubio's failure to answer ("I'm not a scientist man").
"I'm not a scientist, man": well, I'm not a doctor, man, but I know where my femur is. This is, roughly speaking, a question of equivalent difficulty.
I'm not a scientist either, and my first thought was, really? I had literally no idea how old the earth was. I'm not exactly uneducated (what with the whole Oxford post-grad thing) but I wouldn't have got within a billion years of the right answer. (In my defence, I do know that 4004BC isn't the right answer).
I suspect this is yet another illustration of CP Snow's argument that the nation is rigidly divided between arts and science...
