Inventiile mele – Autobiografia lui Nikola Tesla During the early twentieth century, Tesla blazed the trail that electrical technology followed for decades. Nikola Tesla punea accent pe doua lucruri in ceea ce privea succesul in viata: munca pana la extenuare si un corp sanatos care sa sustina munca pana la e.

Serbian-American engineer and physicist Nikola Tesla made dozens of breakthroughs in the production, transmission and application of electric power. He invented the first alternating current AC motor and developed AC generation and transmission technology. Though he was famous and respected, he was never able to translate his copious inventions into long-term financial success—unlike his early employer and chief rival, Thomas Edison.
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.
Inivnentiile 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. He worked there for a year, impressing Edison with his diligence and ingenuity. After months of experimentation, Tesla presented a solution and asked for the money. In and he was granted more than 30 patents for his inventions and invited to address the American Institute of Electrical Engineers on his work.
Westinghouse hired Tesla, licensed the patents for his AC motor and gave him his own lab. In Edison arranged for a convicted New York murderer to be put to death in an AC-powered electric chair—a stunt designed to show how dangerous the Westinghouse standard could be.
But Westinghouse was soon forced by his backers to renegotiate their contract, with Tesla relinquishing his royalty rights.
In the s Tesla invented electric oscillators, meters, improved lights and the high-voltage transformer known as the Tesla coil. He also experimented with X-rays, gave short-range demonstrations of radio communication two years before Guglielmo Marconi and piloted a radio-controlled boat around a pool in Madison Square Garden. Tesla relocated to Colorado Springs for two years, returning to New York in He secured backing from financier J.
Morgan and began building a global communications network centered on a giant tower at Wardenclyffe, on Long Island. Tesla lived his last decades in a New York hotel, working on new inventions even as his energy and mental health faded.
His obsession with the number three and fastidious washing were dismissed as the eccentricities of genius.
Tesla died in his room on January 7, Later that year the U. The AC system he championed and improved remains the global standard for power transmission.

In his 84 years, Thomas Edison acquired a record number of 1, patents singly or jointly and was the driving force behind such innovations as the phonograph, the incandescent light bulb and one of the earliest motion picture cameras. Alexander Graham Bell is best known for his invention of the telephone, for which he received his first patent in Despite the hundreds of lawsuits that would challenge his claim to the invention, none would prove successful.
Born in Scotland and later becoming a U. Italian inventor and engineer Guglielmo Marconi developed, demonstrated and marketed the first successful long-distance wireless telegraph and in broadcast the first transatlantic radio signal.

Developed in the s and s by Samuel Morse and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a lii laid between stations.
In addition to helping invent the telegraph, Samuel Morse InConnecticut-born gun manufacturer Samuel Colt received a U. Colt founded a company to manufacture his revolving-cylinder pistol; however, sales were slow and the The automobile was first invented and perfected in Germany and France in the late s, though Americans quickly came to dominate the automotive industry in the ingentiile half of the twentieth century. Henry Ford innovated mass-production techniques that became standard, and Ford, The Internet got its start in the United States more than 50 years ago as a government weapon in the Cold War.
For years, scientists and Wilbur and Orville Wright were American inventors and pioneers of aviation. In the Wright brothers achieved the first powered, sustained and controlled airplane flight; they surpassed their own milestone two years later when they built and flew the first fully practical Thomas Edison In his 84 years, Thomas Edison acquired a record number of 1, patents singly or jointly and was the driving force behind such innovations as the phonograph, the tewla light bulb and one of the earliest motion picture cameras.
