Nikola Tesla, seated, holding his wireless lightbulb. Yes, indeed, it has no connecting wires. One could place it on a desk, or hold it in the hand and it would remain lit, with no connecting wires. With all other light bulbs wire based, Tesla’s bulbs seem like something from outer space and the distant future. And this is from the late 19th century and early 20th century. Of course, there was a Tesla coil nearby.
In 1960, the name”Tesla” was assigned to the unit of Magnetic Flux Density by the Conference on Weights and Measures. “A particle, carrying a charge of one coulomb, and moving perpendicularly through a magnetic field of one tesla, at a speed of one metre per second, experiences a force with magnitude one newton, according to the Lorentz force law. The tesla can also be expressed as shown in out banknote, 1 Tesla equals 1 weber per meter squared.
The equation adorns the front of this 100 dinari banknote from Serbia. Coincidently, 100 T is the magnetic field strength of the average white dwarf star, which is considered the destiny of our sun.
Niagra Falls fascinated Nikola Tesla from his youth in Serbia. He told his uncle that he wanted to place a wheel under the massive water falls to harness its power.
In America, Tesla designed the first hydroelectric plant and supervised its installation at Niagra Falls in 1895. Thus the electrification of the United States, and indeed, the world, commenced.
The introduction of Tesla’s motor from 1888 onwards initiated what is sometimes referred to as the Second Industrial Revolution, making possible both the efficient generation and long distance distribution of electrical energy using the alternating current transmission system, also of Tesla’s invention (1888). from here.
Regarding the image of the dove on our banknote, the following, by Tesla’s biographer, is selected from this website.
Nikola Tesla fed and cared for several pigeons, among a beautiful white dove with brown-grey tips on her wings was singled out. According to John O`Neil, the author of Tesla`s biography, the inventor loved this dove like he has not loved anyone else. The author claims that Tesla explained to him the connection.
– Yes, I loved that pigeon, I loved her as a man loves a woman, and she loved me. If the pigeon became ill, he would nurse her back to health and as long as she needed him and he could have her, nothing else mattered and there was purpose in his life.
One night as he was lying in bed, she flew in through the window and he knew right away that she had something important to tell him – she was dying.
– And then, as I got her message, there came a light from her eyes – powerful beams of light. Yes, it was a real light, a powerful, dazzling, blinding light, a light more intense than I had ever produced by the most powerful lamps in my laboratory – Tesla told his biographer.
After the dove`s death, something disappeared from Tesla`s life. He knew his life`s work was done for good.
