“I knew that iridium-193 was one of two stable isotopes of iridium, a very rare, very dense metal, but I didn't know that the periodic table even existed.I knew how many zeroes there were in a quintillion, but I thought that algebra lived in ponds.I'd picked up a few Latin words, and a smattering of Elvish, but my French was non-existent.I'd read more than one book of more than one thousand pages (more than once), but I wouldn't have been able to identify a metaphor if it poked me in the eye.By secondary-school standards, I was quite a dunce.”
