The Microwave Oven

The microwave oven is a common appliance that is used in kitchens all around the world today. Many people are so used to using a microwave that they have forgotten about all of the advantages the microwave has given to cooks. Before the microwave was invented, people spent a lot more time in the kitchen! The microwave was invented by a scientist named Percy Spencer in 1945. Spencer was working on a machine called a magnetron that produced microwave radio signals for radar systems. One day, Spencer had a chocolate bar in his pocket that he was saving to eat for a snack later. While he was standing next to the magnetron, he noticed that the chocolate bar was melting in his pocket. He realized that the microwaves had melted it. He did more tests, using popcorn and eggs before he realized that he had just discovered a new, very useful way of cooking. The first microwave oven weighed about 700 pounds (318 kilograms) and was about five feet (152 centimeters) tall. It was about the size of a refrigerator! But, with time and more experiments, the microwave became much smaller and is now used in kitchens everywhere.

[AUDIO: Inventions and Discoveries That Changed History
CD2, Track 9: 
We often wonder if things might or could have been different. Would the world be a better place? What are the advantages or disadvantages of different inventions?

The Wheel
If the Sumerians hadn’t invented the wheel in 5000 B.C.E., they couldn’t have moved heavy
loads. Six thousand years later, the Mayans and Incans in the Americas used the round shape in
their architecture, but they had no wheels.

Airplanes
If the Wright brothers hadn’t invented the first successful airplane, people might still be traveling long distances on ships, and there wouldn’t be as much contact among people on different continents. The Wright brothers first flew in an engine-propelled plane in 1903.

Oil
If people hadn’t discovered a lot of sources of oil, cars that run on gasoline wouldn’t
have become so common. The first commercial oil well drilled in North America
was in Oil Springs, Ontario, Canada in 1858.

Computers
If we didn’t have computers, a lot of work would still be done with paper and pencil, and people in their homes wouldn’t be able to be in contact with the entire world. The first PC was introduced
by IBM in 1981.

Electricity
If electricity hadn’t been discovered, people would probably still be using candles or gaslights. Thomas Edison developed the first incandescent electric light bulb in 1879.

Penicillin
If Dr. Alexander Fleming hadn’t discovered penicillin in 1928, millions of people would have died
from infections. However, the widespread use of penicillin as an antibiotic did not begin until the
1940s, during World War II.
