How A Former Microsoft Exec Mastered The Perfect Slice—Using Science

Who doesn’t love pizza? It’s a magical combination of sauce, cheese, crust, and maybe even a topping or two. Depending on where you eat it, the ratio of sauce and cheese and toppings changes: Neapolitan, NY Style, and Chicago Deep Dish each have a slightly different recipe. And different methods of baking impart their signature flavor on the end result—whether that’s coal, wood, or gas-fired ovens.

Nearly every country in the world has some type of variation on the classic. Author Nathan Myhrvold visited over 250 pizzerias all over the world to appreciate their differences. Then he made over 12,000 pizzas, using physics and chemistry to tweak each one slightly.

Myhrvold and his co-author, chef Francisco Migoya wrote all about the gourmand experiment in a three-volume, 35-pound set of beautifully illustrated and painstakingly researched books.

Ira talks with Nathan Myhrvold, former CTO at Microsoft, founder of Intellectual Ventures and Modernist Cuisine about his discoveries and his most recent book, Modernist Pizza.

E.O. Wilson’s Indelible Mark On Ecology

Ecologist and ant biologist Edward O. Wilson (often called E. O. Wilson) died December 26, at the age of 92. Though he was known for his study of ants and their social behavior, his impact extended much further—from sociobiology, the study of the influence of genetics on behavior, to the way science was taught and understood. His writing twice won the Pulitzer Prize.

Wilson appeared on Science Friday many times. In this short remembrance of Wilson, Ira replays selections from past conversations with the scientist, recorded between 2006 and 2013.

The Fossil—And Family—Records Of Richard Leakey

Paleoanthropologist Richard Leakey died on January 2 at the age of 77. The Kenyan conservationist and fossil hunter was the son of paleoanthropologists Louis and Mary Leakey, who helped redefine the early parts of the human family tree. Richard was part of the team that discovered ‘Turkana Boy,’ a Homo erectus skeleton—one of the most complete early hominin skeletons ever found.

In later years, he was the director of the National Museum of Kenya, the head of the Kenya Wildlife Service, helped found a political party, and led the Kenyan Civil Service in the midst of an anti-corruption campaign.

In this edited interview from 2011, Leakey describes his work in the field, his famous fossil-hunting lineage, and his desire to convince skeptics of the reality of human evolution.
