Nikola Tesla

Nikola Tesla  was a Serbian inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.

Tesla was born on July 10, 1856, in what is now Smiljan, Croatia. Tesla’s interest in electrical invention was spurred by his mother, Djuka Mandic, who invented small household appliances in her spare time while her son was growing up. In 1884, Tesla moved to America, and began to work for Thomas Edison whose DC-based electrical works were fast becoming the standard in the country. However, several months later, the two parted ways due to a conflicting business-scientific relationship.

After struggling with life, in 1887, he finally developed the alternating current system and filed several patents for his work. Meanwhile, his AC system was very interested by George Westinghouse, who later bought his patents for $60,000 in cash and stock. After the war of currents blew out, Tesla did not care so much, and he kept working on his work, and patented several more inventions during this period, including the “Tesla coil,” which laid the foundation for wireless technologies and is still used in radio technology today. In addition to his AC system and coil, he was also a pioneer in the discovery of radar technology, X-ray technology, remote control and the rotating magnetic field—the basis of most AC machinery.  

Current work and technology in Remote Control

A remote control is a component of an electronic device such as a television set, DVD player, or other home appliance, used to operate the device wirelessly from a short distance. Remote control is a convenience feature for the consumer, and can allow operation of devices that are out of convenient reach for direct operation of controls.

In our daily life, we use a lot of remote control technology, like controlling cars, TVs, cameras and etc. The following video demonstrates how  remote control technology works.

Remote control makes our lives easier than before. And I still remembered when I was a kid, I had to walk to the TV to change the channel. Now, we can do it with one click.
