Hard concepts, easy delivery

After Dan Fleisch, a Springfield, Ohio, physics prof and author of A Student’s Guide to Maxwell’s Equations, (considered one of the most readable explanations of difficult electromagnetism concepts) saw a complaint on his Amazon.com page, he promised to make things good. Buyer Michel Cuhaci had posted that his copy of Fleisch’s book was missing pages, so Fleisch vowed to get him a replacement within 24 hours. Except it was Christmas Eve, local couriers wouldn’t promise same-day delivery, all the local bookshops had closed—and Cuhaci lived in Ottawa. So on Christmas morning, to the horror of his girlfriend, the academic caught an empty 6 am flight from Dayton in Ohio to Ottawa, and rented a car at the airport to drive to Cuhaci’s home. Cuhaci, about to leave for a family Christmas dinner, didn’t know who Fleisch was until the author asked "Hardcover or soft?"
