Hello there, I am starting a question blog. You can write the questions in the comment box. And I will answer your questions. I will also make a video on the topics for understanding.
Wilhelm Röntgen was born to Friedrich Conrad .Röntgen, a German merchant and cloth manufacturer, and Charlotte Constanze Frowein. .Röntgen's discovery occurred accidentally in his Wurzburg, Germany, lab, where he was testing whether cathode rays could pass through glass when he noticed a glow coming from a nearby chemically coated screen. He dubbed the rays that caused this glow X-rays because of their unknown nature. It was discovered accidentally On November 8, 1895, Roentgen noticed that when he shielded the tube with heavy black cardboard, the green fluorescent light caused a platinobarium screen nine feet at away to glow - too far away to be reacting to the cathode rays as he understood them. He determined the fluorescence was caused by invisible rays originating from the Crookes tube he was using to study cathode rays (later recognized as electrons), which penetrated the opaque black paper wrapped around the tube. Further experiments revealed that this new type of ray was capable of passing through most substances, including the soft tissues of the body, but left bones and metals visible. One of the earliest photographic plates from his experiments was a film of his wife Bertha's hand, with her wedding ring clearly visible.
Philo Taylor Farnsworth was an American farm boy. He was born on August 19, 1906, in Beaver, Utah. He was the eldest of five children. In 1918, the family moved to a relative's ranch near Rigby, Idaho where his father Boosted his farming income by hauling freight with his horse-drawn wagon. He was a quick student in mechanical and electrical technology. He was an excellent scientist and an inventor at a young age only. He converted his home appliances into electric power during high school. Farnsworth was excelled in chemistry and physics. When he was only 14 years old reamed up his own idea for electronic-rather than mechanical-television while driving a horse-drawn harrow at the family's new farm in Idaho. As he plowed a potato field in straight, parallel lines, he saw television in the furrows. He got the IEEE Morris N. Liebmann Memorial Award
