A Neighbor's Yell About the Chemistry Nobel Revealed a Principle Linking Life and the Universe

My Neighbor, Me, and a Grand Principle

A science writer's neighbor, a chemistry professor, shouts across the court that it's the best day of the year because the Chemistry Nobel goes to Kagan and Soai for homochirality. The explanation: all life's molecules are left-handed, yet lab reactions make both hands equally — until a tiny bias, repeated and accumulated, propagates. The writer realizes the same logic explains why the universe is all matter, and that it vindicates Baby Steps.
