Valarie Thomas Valarie Thomas was born in Maryland in May 1943. When she was young, she was not encouraged by mathematics and science, but she soon became interested in the mystery of technology. At the age of 8, she borrowed a book named "The First E-Book of a Boy" from the library. Her father is also interested in electronics, but he does not help her to complete any projects in this book. In the 1950s, most parents and schools did not consider electronics and other science subjects suitable for women.
The team led by Thomas developed Landsat, an image processing system that sends the first image of the satellite to the Earth. She invented and holds patents for illusion emitters that use concave mirrors to create 3D images. This technology is still being used by NASA, surgeon and television screen producer. Even when I was young, the three inventors showed enthusiasm for technology and innovation. Sadly, they also experienced isolation and racial discrimination. Can you imagine the personal and professional issues they have to face? But they keep chasing their dreams and keep changing the world. These inventors are not only praise worthy examples for future inventors but also a powerful example of the possibilities, talents and wisdom that we should encourage students from all countries.
Thomas Alva Edison (1847-1931) is an American inventor (also known as Menlo Park Elf), and many of his inventions have revolutionized the world. His work includes inventions of incandescent light bulbs, phonographs, gramophone records, carbon fiber phone transmitters, film projectors. Edison tried the filament of thousands of light bulbs and found the right material to turn it on, to last longer, and cheaper. In 1879, Edison discovered that the carbon filament of the anaerobic light bulb did not burn for a long time. This incandescent light bulb revolutionized the world
Thomas Edison 's first wonderful invention was a tin foil gramophone. While working to improve the efficiency of the telegraph transmitter, he noticed that the machine's tape generates spontaneous noise during fast playback. This wondered if he could record phone messages. He began experimenting with the diaphragm of the telephone receiver and connected the needle to the telephone receiver based on the fact that the needle could pierce the paper to record information. In his experiment he could try the stylus with a tin cylinder of tin, but surprisingly he played the text that he recorded.
