A Smart Response

My wife and I were comparing notes the other day. 'I have a higher IQ, did better on my SAT's, and make more money than you,' she pointed out.
'Yeah, but when you step back and look at the big picture, I’m still ahead,' I said.

He trained as a medical doctor in Moscow. In addition, he studied mathematics and physics on his own. His doctoral thesis (1912) at Moscow University was a fundamental investigation in prequantum photochemistry. He supported the October Revolution.
