Nikola Tesla: the last genius
Few characters in science history have around themselves an aura of legend like the inventor Nikola Tesla (1856-1943).
Those who know the story of Nikola Tesla, know that any term used to describe his profession might seem as reductive. Scientist, physicist, engineer, inventor, none of these words describe sufficiency the life of Nikola Tesla. Maybe only genius can minimally describe the life of this man. Main actor of the electricity revolution, Tesla was the prototype of the mad genius. He invented the Tesla coil, whose impressive electrical discharges were the symbol of the mad scientist’s laboratory. He had at the same time superhuman mental abilities which made him able to think in his mind complex electrical machines and build them without taking any notes.
Nikola Tesla was a visionary who changed the history of humanity with his inventions. No wonder then if there is a large community who made the brilliant scientist a kind of divinity. Tesla is according to them the true father of an impressive amount of fundamental inventions like the transistor, the radio, the radar, the X-ray as well as the alternating current.
Tesla’s vision was always ahead of his contemporaries; he imagined already two century ago, a world where people could communicate with radio waves, illuminate cities without using wires. He was not afraid by the innovation: for this aspect Tesla will always be an indisputable example.
Be a genius of this magnitude inevitably isolates you from the world and leads to have many enemies. Reading the Nikola Tesla’s biography is quite hard. All the injustices that this genius underwent, give to the reader a state of sadness and anguish. For this reason I decided to write this article, in order to commemorate a genius to whom we owe a lot.
Below you will find 10 of the thousands inventions of Nikola Tesla, even if many of these are not attributed to him yet.
1. AC alternating current;
The alternating current put the basis of the industrial revolution. It is probably the Nikola Tesla’s invention which has changed more the destiny of humanity. After winning the current battle against Thomas Edison, the AC influenced all human activities, changing forever our history.
Of course he did not invent the light, but he discovered how to channel it making possible for example the creation of neon light.
3. X Rays;
With the idea in mind that everything we need is already present in nature, Nikola Tesla has contributed significantly to the development of the x-ray technology.
Generally we refer to Marconi as inventor of the radio, but Nikola Tesla deposited many years before a patent explaining the operation of the radio.
5. Remote control;
Although later developed during the two world wars, this is one of many revolutionary inventions made by Nikola Tesla. Even if today it might seem obvious, 100 years ago the idea to control the movements of any object by remote control was considered magic.
6. Electric motor;
The engine of Nikola Tesla succeeds to operate using only magnets and without any fuel.
With the idea that all living things are driven by electrical impulses, Nikola Tesla put the basis to the creation of robotics.
Used in thousands of ways, the laser has revolutionized many fields, including surgery.
Through the Tesla tower, pulses can travel around the globe without wires.
10. Free energy.
Nikola Tesla suggested the use of the earth energy to feed human activities, leading consequently to a world less dependent of fossil fuels and with less wars. A world where the energy might be free for everyone. This idea of free energy and freedom was presumably the cause of the marginalization that Nikola Tesla suffered.
