He worked there for a year, impressing Edison with his diligence and ingenuity. At one point Edison told Tesla he would pay $50,000 for an improved design for his DC dynamos. After months of experimentation, Tesla presented a solution and asked for the money. Edison demurred, saying, “Tesla, you don’t understand our American humor.” Tesla quit soon after.]]> 2019-05-06 18:27:19 UTC https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357334788 jakupovicf8831 https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357335775 2019-05-06 18:29:11 UTC https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357335775 jakupovicf8831 https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357336354 he Earthquake Machine


In 1893, Tesla patented a steam-powered mechanical oscillator that would vibrate up and down at high speeds to generate electricity. Years after patenting his invention he told reporters that one day while attempting to tune his mechanical oscillator to the vibration of the building housing his New York City laboratory, he caused the ground to shake. During the test, Tesla continuously turned up the power and heard cracking sounds. “Suddenly,” he recalled, “all the heavy machinery in the place was flying around. I grabbed a hammer and broke the 
machine. The building would have been down about our ears in another few minutes.” Police and ambulances arrived on the scene to attend to the commotion, but Tesla told his assistants to remain quiet and tell the police that it must have been an earthquake.


Thought camera 

Tesla believed it could be possible to photograph thoughts. The inspiration came while he was doing experiments in 1893, Tesla told a newspaper reporter decades later: “I became convinced that a definite image formed in thought must, by reflex action, produce a corresponding image on the retina, which might possibly be read by suitable apparatus.” The inventor conceived of reflecting an image on an artificial retina, taking a photograph and projecting the image on a screen. “If this can be done successfully, then the objects imagined by a person would be clearly reflected on the screen as they are formed,” he said, “and in this way every thought of the individual could be read. Our minds would then, indeed, be like open books.”

Nikola Tesla was born in 1856 in Smiljan, Croatia, then part of the Austro-Hungarian Empire. His father was a priest in the Serbian Orthodox church and his mother managed the family’s farm. In 1863 Tesla’s brother Daniel was killed in a horse riding accident. The shock of the loss unsettled the 7-year-old Tesla, who reported seeing visions, the first signs of his lifelong mental illnesses.

Tesla studied math and physics at the Technical University of Graz and philosophy at the University of Prague. In 1882, while on a walk, he came up with the idea for a brushless AC motor, making the first sketches of its rotating electromagnets in the sand of the path. Later that year he moved to Paris and got a job repairing direct current (DC) power plants with the Continental Edison Company. Two years later he immigrated to the United States.

Part 2 : Tesla's inventions 

The Tesla Coil

Among his numerous innovations, Nikola Tesla dreamed of creating a way to supply power to the world without stringing wires across the globe. The inventor came close to accomplishing this when his "mad scientist" experiments with electricity led to his creation of the Tesla coil.


The first system that could wirelessly transmit electricity was the Tesla coil, a truly revolutionary invention. Early radio antennas and telegraphy used the invention, but variations of the coil can also do things that are just plain cool — like shoot lightning bolts, send electric currents through the body, and create electron winds.

AC Current 

Most students of electricity begin their study with what is known as direct current (DC), which is electricity flowing in a constant direction, and/or possessing a voltage with constant polarity. DC is the kind of electricity made by a battery (with definite positive and negative terminals), or the kind of charge generated by rubbing certain types of materials against each other.


Alternating Current vs Direct Current

As useful and as easy to understand as DC is, it is not the only “kind” of electricity in use. Certain sources of electricity (most notably, rotary electromechanical generators) naturally produce voltages alternating in polarity, reversing positive and negative over time. Either as a voltage switching polarity or as a current switching direction back and forth, this “kind” of electricity is known as Alternating Current (AC): Figure below

All the evidence, documents and files of his death were stolen and never found. jakupovicf8831 https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357761897 2019-05-07 18:06:08 UTC https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357761897 All in all know you know more about nikola tesla then someone that hasn't heard of him. jakupovicf8831 https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357768131 2019-05-07 18:18:24 UTC https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357768131 jakupovicf8831 https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357768736 2019-05-07 18:19:32 UTC https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357768736 jakupovicf8831 https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357769038 2019-05-07 18:20:06 UTC https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357769038 Did you also know that Nikola Tesla made his own electric car that could run without gas and without having to charge them that's when the government had to destroy it because they weren't getting paid enough because he didn't have to charge it, also because he don't have to pay gas that's why they made Tesla cars after he died so they can make it chargable. jakupovicf8831 https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357769515 2019-05-07 18:21:03 UTC https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357769515 jakupovicf8831 https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357773274 2019-05-07 18:28:31 UTC https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357773274 jakupovicf8831 https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357777138 2019-05-07 18:36:58 UTC https://padlet.com/jakupovicf8831/12yda6shzzo2/wish/357777138
