"meals in a minute"

"meals in a minute" 
T­he microwave oven could be one of the great inventions of the 20th century. Today hundreds of millions of homes worldwide have one. In 1947, Raytheon built the first microwave oven, the Radarange. As you know that microwave ovens are popular because they cook food in an amazingly short amount of time.
Microwave Cooking ....
You often hear that microwave ovens cook food "from the inside out." What does that mean? Here's a gr8 answer about microwave cooking. In microwave cooking, the radio waves penetrate the food and excite water and fat molecules pretty much evenly throughout the food. No heat has to migrate toward the interior by conduction. There's heat everywhere all at once because the molecules are all excited together.
While in a conventional oven, the heat has to migrate by conduction from the outside of the food toward the middle.
