Microwaves provide an energy-efficient way to heat food quickly and easily; however, they don't always heat food evenly and can potentially be harmful if food is not heated properly. Microwaves are useful for preparing convenient meals and for defrosting meats immediately before being transferred to the oven or grill.Know More
According to The University of Texas Health Centers Northeast, carcinogenic compounds can potentially be released when cooking steak or hamburger in a pan or on the grill, but microwaving meats beforehand helps to prevent this.
Microwaves have their limitations. Only "microwave-safe" dishes should be used in the microwave; otherwise, unsafe chemicals like polyvinyl chloride may contaminate the food. According to foodsafety.gov, it’s important to follow directions on the boxes of convenient meals because it can be easy to undercook or unevenly cook the food in the microwave. Covering, stirring and rotating food may be necessary to ensure it is prepared safely. If these directions are ignored, the food may not be heated fully and bacteria will not be killed, causing food-borne illness. It’s important to also recognize that a microwave is not the same thing as a convection oven or a toaster oven.
The wattage of a microwave is also important — if the microwave’s wattage is lower than recommended, the food may not be heated entirely within the recommended time frame. If it is unclear whether a food has been heated properly, use a food thermometer to check the temperature.Learn more about Inventions
The history of microwave communication begins with Western Union sending the first successful microwave message between New York and Pennsylvania in 1945 and continues to the present day, according to DPS Telecom. Since the invention of fiber optic cables, microwave towers are largely only used in remote areas.Full Answer >
Plans for the first microwave were patented on Oct. 8, 1945, but the microwave itself was not actually created until 1947. A man named Percy Spencer came up with the idea for the invention, but his employer, Raytheon, officially filed the patent request.Full Answer >
The microwave oven was patented on October 8, 1945 by the company Raytheon. At the time, it was called the Radarange. It wasn't until 1967 that the microwave was more affordable and reasonably sized.Full Answer >
The microwave oven was invented by Percy Spencer in 1946 after noticing that the chocolate bar in his pocket was melting as he stood in front of the magnetron that powered the radar he was working with. The first microwave model was not very user-friendly, being nearly 6 feet high and weighing more than 700 pounds.Full Answer >
