Interesting facts about the microwave.

In 1946, engineer Percy Spencer, who worked at Raytheon Corporation, experimented with a magnetron tube. And suddenly he saw that the candy in his pocket had melted! This surprised him, and he continued experimenting with products by placing a magnetron in a metal box. Electromagnetic waves of small length (12 cm) cannot pass through metal and are absorbed by products, causing the latter to heat up.

An interesting fact, the first commercial microwave oven was released in 1947, it cost $ 5,000 and had dimensions of about 2 meters.

Microwave ovens have enjoyed great success in countries that have little gas, such as Japan.

Interesting facts about rubber.

There is a misconception that Europeans owe the invention of rubber to Columbus. In fact, the navigator only left a description of how the natives of the islands of Haiti played with a ball made of thickened milky juice that flowed from cuts on the bark of the Brazilian hevea. When the sap dripped from the tree, it seemed to the Indians that it was crying. Therefore, they began to call this plant a "crying tree– - from the Indian words kau ("tree") and uchu ("cry"). Much later, Europeans who visited America got to know rubber better and even learned, like the locals, to soak their raincoats with the juice of a rubber-bearing tree. But rubber came to the Old World only in 1751. A little frozen juice was brought by mathematician Charles La Condamine. He watched his "trophy" for a long time, but could not figure out what benefit rubber could bring to him personally and to humanity as a whole. Interesting facts about rubber Elasticity syndrome

Interesting facts about cockroaches.

Cockroaches have white blood that flows freely through the body. In other words, they do not have blood vessels designed to conduct blood. Interestingly, even the heart of this insect is like a simple tube that pumps blood to the front and back of the body. The eye of this insect has 4000 segments that help to see all directions at one time. An interesting fact is that a cockroach can live without a head, since the brain of a cockroach is not in the head, but throughout the body. But without a head, they can die within ten days, due to lack of water, because they have nothing to drink. Interestingly, cockroaches spend most of their time (about 75%) in hibernation. Cockroaches are widely used in folk medicine. Cockroach tea is used to treat dropsy, and cockroaches fried with garlic are used to treat stomach upset. In the east, cockroaches are used in dried and powdered form for the treatment of the urinary tract. Cockroaches can live for

Interesting facts about Bruce Lee.

At the age of 32, during the filming of the movie "The Game of Death", Bruce Lee died unexpectedly. Interestingly, the film company rewrote the script as if Bruce's character faked his death to get away from the mafia. Moreover, the film included footage from the real funeral of Bruce Lee — including close-up shots of an open coffin. Most martial arts movies speed up to make beautiful fighting scenes, but not in the case of Bruce Lee. His movements were too fast for the eye and therefore the battle scenes were shot at a frequency of 32 frames per second, and then slowed down so that the audience could see his movements. Bruce Lee's family gave him the feminine name "Little Phoenix" because they believed that evil spirits did not like boys in the family (their first-born son died in infancy). And the name Bruce was recorded in his documents by a nurse from the hospital in San Francisco, where he was born (Bruce's father was traveli
