Physics of Cooking Public Lecture


David Weitz, Harvard University will deliver a public lecture on "The Physics of Cooking." The lecture will take place at 7:00 p.m., in Room 150 of the Tate Laboratory of Physics. It will be preceded by a reception at 6:45 p.m. in the foyer of the building. The lecture will also be webcast and available online after the fact.

Do you want to understand how (and why) food foams are made or why the elasticity of steak matters? Why do some chefs use liquid nitrogen (at about -320 degrees F) to freeze ingredients? The School of Physics and Astronomy at the University of Minnesota is proud to announce a public lecture given by Professor David Weitz on February 9, 2012. Dr. Weitz’ lecture is entitled “Physics and Cooking” and is inspired by understanding the science of pioneering approaches to preparation and presentation of foods at several famous restaurants.

This talk will present some examples of physics and science of cooking and will include demonstrations. The examples are based on an introductory science course offered at Harvard University by Weitz and a team of chefs, including Ferran Adria, and the Alícia Foundation, that explores a new way of motivating interest in science and teaching it to non-scientists. The theme of the course is the connections between cooking, soft matter physics, materials science and organic chemistry. The science of several innovative techniques in cooking, including foams and use of gelation, as well as more common processes, will be explored. Recipes used in the talk are available.

Biography: Weitz received his Ph.D. from Harvard. He worked at Exxon Research and Engineering as a research physicist for nearly 18 years, and then became a Professor of Physics at the University of Pennsylvania. He moved to Harvard about 12 years ago, and is currently Professor of Physics and Applied Physics. He is also the director of Harvard's Materials Research Science and Engineering Center. He helped arrange the establishment of the BASF Advance Research Initiative at Harvard, which he co-directs. His research interests are in soft matter physics and biophysics. He is a member of the National Academy of Sciences and the American Academy of Arts and Sciences.
