Black Ice and Near-Death on I-91
In the most recent issue of the The New Yorker, writer John Seabrook describes how he was almost killed when his pick-up truck hit a patch of black ice on I-91 north of Springfield. Two professors from Dartmouth's Thayer School, which has one of the leading ice labs in the world, figure prominently in the article.
Professor Erland Schulson details for Seabrook the mechanics of ice down to the molecular level. He says that "melting ice with a thin layer of water on top is as slippery as the natural world gets."
When Seabrook asked if there was a solution to the problem of black ice, Professor, Don Perovich, also participating in the interview responded.
"To tell you the truth, I try not to be the first person on the road in the morning because you really can't see it."
