HOW DOES SANTA MANAGE TO DELIVER PRESENTS TO AN ESTIMATED 842 MILLION HOUSEHOLDS IN A SINGLE NIGHT? WHAT COULD WE DO TO GUARANTEE A WHITE CHRISTMAS EVERY YEAR? These are among the questions explored in an irresistibly witty book that illuminates the cherished rituals, legends, and icons of Christmas from a unique and fascinating perspective: science.
