  Microwave cooking is probably the best cooking discovery besides fire.In fact, it might be better than fire, since microwaves, instead of a flame or an electric element, cook the food.

  Microwaves are short radio waves, similar to heat and light waves.They work by movement.They cause the molecules(分子)in food to move, which produces friction(摩擦力).(It’s similar to rubbing your hands together when they’re cold.)The friction produces heat in the food(not in the oven), and the heat cooks the food.

  There is a legend behind the use of microwaves for cooking.

  Percy Le Spencer was employed by the Raytheon Company during the World War Ⅱ.One day on 1942 he was working with magnetrons(电磁管), which can produce microwaves.When he pulled a candy bar from his pocket, it was a melted mess.Although Spencer was working on scientific experiments, not trying to invent a new way of cooking, he realized that it was the microwaves that had melted the candy.Spencer knew that if microwaves melted candy, they would cook other foods as well.The Raytheon Company agreed, and in 1947 it introduced its Radarange to the public.

  The first ovens were suspected(怀疑)of causing health problems, but the new models were safe when the factory’s instructions were followed.Microwave cooking now can be found in many homes all over the world.
