Percy LeBaron Spencer

Percy Spencer was working with radar for the army when he discovered that microwaves from the machine had melted the chocolate in his pocket. He experimented and found that microwaves could pop popcorn within a minute. Spencer then built a metal box and cooked food by sending microwaves through a hole, inventing the microwave oven by accident. The document also expresses the opinion that the most important invention has been the car, created by Karl Benz in 1885 to use an internal combustion engine, which modernized transportation.

Percy leBaron Spencer, an engineer, was working of radar

for the army. One day he was walking past a machine


when the chocolate bar in his pocked melted. He was
curious, so he did a test. He put a small bowl of popcorn
in from of the machine. Has expected, a minute later is
started popping and jumping out of the bowl.
Spencer realized the microwaves from the radar were
heating the food. Next, he made a metal box and sent
microwaves into it through a hole. When he put some
food in the box, it cooked. This was the hear microwave
oven – invented totally by chance.
In my opinion, the most important invention has been
cars. Karl Benz in 1885 created the first automobile
vehicle by internal combustion engine with gasoline. He
changed the world by modernizing the way people
transport themselves. In my view, that’s really important,
specifically because it is a big step in the technological
advance of humanity
