This article contains a common misconception about the greenhouse effect. It states, “The newly detected gas is chemically similar to sulfur hexafluoride–another strong absorber of solar radiation . . .” (emphasis mine). While this statement may be true, it is irrelevant to the greenhouse efficiency of a gas. The mechanism of the greenhouse effect involves […]

Chomping to Win
Even the simplest of games can pose tough mathematical challenges. One such game is Chomp. It was invented in the early 1970s by David Gale of the University of California, Berkeley, who was also responsible for the board game Bridg-it, and it was later dubbed Chomp by Martin Gardner. Chomp on a 5-by-6 field. The […]
