- How Microwave Ovens Work. The invention of the microwave is a fantastically simple concept. Microwaves have a frequency that can penetrated water, fat, and sugar molecules and excite them. For a molecule to be excited the electrons orbiting the nucleus have to jump up energy levels.

Who Invented Microwave Popcorn That research led to the first microwave popping bag, of which these two gentlemen named above have the patent. Even so, these first bags of microwavable popcorn were just the kernels of corn combined with a convenient popping bag. What we think of modern microwave popcorn was yet to come.

- On October 8, 1945 Raytheon filed a U.S. patent for Spencer’s microwave cooking process, and a prototype was developed for testing. It was almost six feet tall, weighed 670 pounds, and sold for the equivalent of $20,000 in today’s dollars.

Who Invented the MRI Machine Who Invented the MRI Machine. Magnetic Resonance Imaging, or an MRI, is a medical device that is used to see layer by layer images of the human body in order to make an accurate diagnosis of a disease, injury, or other health concern. It was invented by Raymond Vahan Damadian, who was born in 1936 and lived in the Armenian section of New York. He studied mathematics and medicine, but also studied the violin at Juilliard for 8 years. Outside of his invention of the MRI machine, here is a look at his life work up to this point as well:

The Microwave Oven Was Invented by Accident by a Man Who was Orphaned and Never Finished Grammar School The Microwave Oven Was Invented by Accident by a Man Who was Orphaned and Never Finished Grammar School. Today I found out the microwave oven was invented by accident by a man who was orphaned and never finished grammar school. The man was Percy Spencer. At the age of just 18 months old, Spencer’s father died and his mother soon left him to his aunt and uncle. His uncle then died when Spencer was just seven years old.

Who Invented Microwave Popcorn Raytheon loved the idea and so did Spencer. They realized they were onto something with the food heating that could happen and this eventually led to the invention of the microwave. Spencer himself actually holds the patent for microwave popcorn. It could be said, however, that the invention of microwave popcorn is what actually led to the invention of the microwave.

- This Day in History: 03/07/1876 - Alexander Graham Bell Patents the Telephone. Captain James Cook discovered the Northwest coast of the Americas on this day. He discovered what is now the coast of Oregon, and was the first European to do so. German troops violated the Treaty of Versailles on this day in 1936. Broadway musicals were put on pause for four days during the musician walkout. Also, Alexander Graham Bell patented the telephone, or what he called the electric speech machine.

Who Invented Microwave Popcorn The warm, buttery smell of popcorn wafts through the air and the familiar popping sound seems to spur hunger on whenever it is heard. For many years, however, the only way to make popcorn was on the stove or through the use of an air popper. It wasn’t until the early 1980’s that microwave popcorn was able to join this food product family thanks to the distribution efforts of General Mills.

Alexander Graham Bell Alexander Graham Bell was a Scottish-born[N 3] scientist, inventor, engineer, and innovator who is credited with patenting the first practical telephone and founding the American Telephone and Telegraph Company in 1885. Bell's father, grandfather, and brother had all been associated with work on elocution and speech and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventua

- John Mauchly Facts. John Mauchly (1907-1980) was the visionary and co-inventor (with J.P. Eckert) of one of the first electronic computers. Though he is not well known and his career was frustrating, Mauchly essentially invented computer science and was the first computer entrepreneur.

Who is credited as inventing the telephone? Was it Alexander Graham Bell, Elisha Gray, or Antonio Meucci? Alexander Graham Bell is often credited as the inventor of the telephone since he was awarded the first successful patent. However, there were many other inventors such as Elisha Gray and Antonio Meucci who also developed a talking telegraph. Attributing the true inventor or inventors to a specific invention can be tricky business.

Microwave oven A microwave oven (commonly referred to as a microwave) is a kitchen appliance that heats and cooks food by exposing it to microwave radiation in the electromagnetic spectrum. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.
