Latest Mind and Matter column in the Wall Street Journal, on `unlearning’: For adults, one of the most important lessons to learn in life is the necessity of unlearning. We all think that we know certain things to be true beyond doubt, but these things often turn out to be false and, until we unlearn them, […]

Here’s what it says (from UPI): “Production of ‘unconventional’ gas in the U.S. has rocketed in the past few years, going beyond even the most […]

Clever people don’t like to think that individual cleverness is not what counts The Edge’s Annual Question is a great compilation of brief effusions from science groupies like me.
