Looking Back On A Century Of Science, Holiday Math. December 24, 2021, Part 2

Looking Back On A Century of Science In 1921, the discovery of radium was just over 20 years in the past. And the double helix of DNA was still over thirty years in the future. That year, a publication that came to be the magazine Science News started publication, and is still in operation today. Editors Nancy Shute and Elizabeth Quill join Ira to page through the magazine’s archives, with over 80,000 articles covering a century of science—from the possibilities of atomic energy to discussions of black holes, to projections of the rise of the avocado as a popular fruit. There are mysteries—are spiral nebulae other universes? And there are missteps, like the suggestion that the insecticide DDT should be incorporated into wall paint.   How Can Math Make Your Holidays Merrier? Stumped on how to wrap an oddly shaped gift? Trying to figure out how to create the perfect Secret Santa game? Need to weigh the cost/benefit analysis of giving a present to that distantly-related aunt? Math is here to help make your holidays merrier. Mathematician Hannah Fry joins us to talk about how to view the holidays—and the world—from a mathematical angle. And in The Indisputable Existence of Santa Claus, she and co-author Thomas Oléron Evans share their tips on how to have a geometrically superior holiday season. Subscribe to this podcast.
