In just a few short years, mobile phones from huge and heavy, with limited functionality have become small, lightweight and comfortable multifunctional devices. What about the computers that originally occupied entire rooms?
But even household appliances such as vacuum cleaners, refrigerators, and washing machines are undergoing transformations and technological advances. Thanks to Business Insider, we can understand what some of the innovative inventions looked like when they first appeared.
It is not clear who invented the microscope, but it is known that it appeared around 1590. Hans Lippershey received the first patent for a telescope in 1608, and Hans and Zacharias Jansen, father, and son mentioned the microscope in 1590.
The first bikes were wooden and had no pedals. The bike was invented in 1817 by Carl von Drais. Later in 1860 bicycle pedals were invented but by other scientists.
Before the advent of electric refrigerators, these appliances were “ice boxes” that were made of wood and filled with ice. Iceboxes used different materials to keep the ice longer such as cork, tin, zinc, sawdust, and seaweed. In 1835 Jacob Perkins patented a refrigerator using liquid ammonia.
4. Light bulb
Thomas Edison was often credited with inventing the light bulb in 1879, but other inventors played a role in its creation. He patented the first light bulb in 1879, but its history dates back to 1800 with the advent of the first electric inventor, Alessandro Volta. Humphrey Davy invented the first electric lamp in 1802.
5. Movie camera
George Eastman and Thomas Edison have been instrumental in the creation of the film industry. Edison Patent Cinematographer and Cinematographer in 1891 Eastman invented the camera box in 1888 and the roller film in 1889.
6. Vacuum cleaner
The first vacuum cleaner was patented by inventor Hubert Cecil Booth in 1901. But she did not suck out the dirt but blew it with compressed air. The first “upright” vacuum cleaners with bags appeared in 1907.
7. Electric washing machine
Alva John Fisher invented the electric washing machine in 1908 and patent design in 1910.
Microwaves were invented by accident while engineer Percy Lebaron Spencer tested magnetrons. Magnetrons are vacuum tubes that produce microwave radiation and are used in radar systems. Spencer noticed that the chocolate in his pocket was melting as he tested them. He invented the microwave oven by constructing a metal box around the magnetrons since microwaves cannot pass through metal and find that his discovery can heat food faster than ovens. He filed a patent in 1945.
The first VCR was invented by Charles Ginsberg in 1951. The first VCR sold for $ 50,000 in 1956.
The Soviet Union launched the first Sputnik I satellite in 1957. He had the size of a beach ball and circled the Earth in 98 minutes. His launch marks the beginning of the space race between the US and the Soviet Union.
