Physics and Cooking Physics plays a role in everything we do, including cooking. Have you ever been using a microwave and said to yourself, "How does this thing work?", or wondered what the difference between a convection oven and a conventional oven is. These questions can be answered using physics. This science tells us that cooking is based on the three methods of heat transfer, Conduction, Convection, and Radiation. http://www.qvc.com/asp/frameset
