      Here's a task for you to try:
      Go check your encyclopedia to find the answers to the following
      questions: (answers are given in parentheses)

      1) Who invented the radio? (Marconi)

      2) Who discovered X-rays? (Roentgen)

      3) Who invented the vacuum tube amplifier? (de Forest)

      In fact, while you're at it, check to see who discovered the
      fluorescent bulb, neon lights, speedometer, the automobile ignition
      system, and the basics behind radar, electron microscope, and the
      microwave oven.

      Chances are that you will see little mention of a guy named Nikola
      Tesla, the most famous scientist in the world at the turn of the
      century.

      In fact, few people today have ever heard of the guy. Good old Tommy
      Edison made sure of that.

      After all, Tesla was considered an eccentric who talked of death
      rays that could destroy 10,000 airplanes at a distance of 250 miles,
      claimed to be able split the Earth in two, believed that both voice
      and image could be transmitted through the air (in the late 1800's),
      and essentially told Edison to take his DC electrical system and
      stick it you know where.

      In other words, anyone that has even heard of Tesla probably
      considers him to be a first class wacko.

      But, the times are a changin'.

      The problem is that Tesla probably could do all these things that he
      claimed were possible. In fact, Tesla invented every single one of
      the items listed above (but gets no credit) and much more. Look
      around you and chances are Tesla is somehow responsible for most of
      the things that make modern life so modern.

      No doubt about it, Nikola Tesla is the greatest mind since da
      Vinci.

      So who is this genius?

      Little Nicky Tesla was born in Smijlan, Croatia way back in 1856. He
      had an extraordinary memory and spoke six languages. He spent four
      years at the Polytechnic Institute at Gratz studying math, physics,
      and mechanics.

      What made Tesla great, however, was his amazing understanding of
      electricity. Remember that this was a time when electricity was
      still in its infancy. The lightbulb hadn't even been invented yet.

      When Tesla first came to the United States in 1884, he worked for
      Thomas Edison. Edison had just patented the lightbulb, so he needed
      a system to distribute electricity.

      Edison had all sorts of problems with his DC system of electricity.
      He promised Tesla big bucks in bonuses if he could get the bugs out
      of the system. Tesla ended up saving Edison over $100,000 (millions
      of $$$ by today's standards), but Edison refused to live up to his
      end of the bargain.

      Tesla quit and Edison spent the rest of his life trying to squash
      Tesla's genius (and the main reason Tesla is unknown today).

      Tesla devised a better system for electrical transmission - the AC
      (alternating current) system that we use in our homes today. AC
      offered great advantages over the DC system. By using Tesla's newly
      developed transformers, AC voltages could be stepped up and
      transmitted over long distances through thin wires. DC could not
      (requiring a large power plant every square mile while transmitting
      through very thick cables).

      Of course, a system of transmission would be incomplete without
      devices to run on them. So, he invented the motors that are used in
      every appliance in your house. This was no simple achievement -
      scientists of the late 1800's were convinced that no motor could be
      devised for an alternating current system, making the use of AC a
      waste of time. After all, if the current reverses direction 60 times
      a second, the motor will rock back and forth and never get anywhere.
      Tesla solved this problem easily and proved everyone wrong.

      He was using fluorescent bulbs in his lab some forty years before
      industry "invented" them. At World's Fairs and similar exhibitions,
      he took glass tubes and molded them into the shapes of famous
      scientists' names - the first neon signs that we see all around us
      today. I almost forgot - Tesla designed the world's first
      hydroelectric plant, located in Niagara Falls. He also patented the
      first speedometer for cars.

      Word began to spread about his AC system and it eventually reached
      the ears of one George Westinghouse.

      Tesla signed a contract with Westinghouse under which he would
      receive $2.50 for each kilowatt of AC electricity sold.

      Suddenly, Tesla had the cash to start conducting all the experiments
      he ever dreamed of.

      But Edison had too much money invested in his DC system, so Tommy
      did his best to discredit Tesla around every turn. Edison constantly
      tried to show that AC electricity was far more dangerous than his DC
      power.

      Tesla counteracted by staging his own marketing campaign. At the
      1893 World Exposition in Chicago (attended by 21 million people), he
      demonstrated how safe AC electricity was by passing high frequency
      AC power through his body to power light bulbs. He then was able to
      shoot large lightning bolts from his Tesla coils to the crowd
      without harm. Nice trick!

      When the royalties owed to Tesla started to exceed $1 million,
      Westinghouse ran into financial trouble. Tesla realized that if his
      contract remained in effect, Westinghouse would be out of business
      and he had no desire to deal with the creditors. His dream was to
      have cheap AC electric available to all people. Tesla took his
      contract and ripped it up! Instead of becoming the world's first
      billionaire, he was paid $216,600 outright for his patents.

      In 1898, he demonstrated to the world the first remote controlled
      model boat at Madison Square Garden. So you can thank Tesla for the
      invention of those remote controlled planes, cars, and boats (and
      televisions!), also.

      Tesla had a dream of providing free energy to the world. In 1900,
      backed by $150,000 from financier J.P. Morgan, Tesla began
      construction of his so called "Wireless Broadcasting System" tower
      on Long Island, New York. This broadcasting tower was intended to
      link the world's telephone and telegraph services, as well as
      transmit pictures, stock reports, and weather information worldwide.
      Unfortunately, Morgan cut funding when he realized that it meant
      FREE energy for the world.

      Many stories claim that the U. S. government destroyed the tower
      during World War One for fear that the German u-boat spies would use
      the tower as a landmark to navigate by. In reality, Tesla ran into
      financial trouble after Morgan cut funding for the project and the
      tower was sold for scrap to pay off creditors.

      The world thought he was nuts - after all, transmission of voice,
      picture, and electricity was unheard of at this time.

      What they didn't know was that Tesla had already demonstrated the
      principles behind radio nearly ten years before Marconi's supposed
      invention. In fact, in 1943 (the year Tesla died), the Supreme Court
      ruled that Marconi's patents were invalid due to Tesla's previous
      descriptions. Still, most references do not credit Tesla with the
      invention of radio. (Sidenote: Marconi's radio did not transmit
      voices - it transmitted a signal - something Tesla had demonstrated
      years before.)

      At this point, the press started to exaggerate Tesla's claims.

      Tesla reported that he had received radio signals from Mars and
      Venus. Today we know that he was actually receiving the signals from
      distant stars, but too little was known about the universe at that
      time. Instead, the press had a field day with his "outrageous"
      claims.

      In his Manhattan lab, Tesla made the earth into an electric tuning
      fork. He managed to get a steam-driven oscillator to vibrate at the
      same frequency as the ground beneath him (like Ella Fitzgerald
      breaking the glass with her voice in those old Memorex
      commercials).

      The result? An earthquake on all the surrounding city blocks. The
      buildings trembled, the windows broke, and the plaster fell off the
      walls.

      Tesla contended that, in theory, the same principle could be used to
      destroy the Empire State Building or even possibly split the Earth
      in two. Tesla had accurately determined the resonant frequencies of
      the Earth almost 60 years before science could confirm his results.

      Don't think he didn't attempt something like splitting the Earth
      open (well, sort of).

      In his Colorado Springs lab in 1899, he sent waves of energy all the
      way through the Earth, causing them to bounce back to the source
      (providing the theory for today's accurate earthquake seismic
      stations). When the waves came back, he added more electricity to
      it.

      The result? The largest man-made lightning bolt ever recorded - 130
      feet! - a world's record still unbroken!

      The accompanying thunder was heard 22 miles away. The entire meadow
      surrounding his lab had a strange blue glow, similar to that of St.
      Elmo's Fire.

      But, this was only a warm-up for his real experiment! Unfortunately,
      he blew out the local power plant's equipment and he was never able
      to repeat the experiment.

      At the beginning of World War I, the government desperately searched
      for a way to detect German submarines. The government put Thomas
      Edison in charge of the search for a good method. Tesla proposed the
      use of energy waves - what we know today as radar - to detect these
      ships. Edison rejected Tesla's idea as ludicrous and the world had
      to wait another 25 years until it was invented.

      His reward for a lifetime of creativity? The prized (to everyone but
      Tesla) Edison Medal! A real slap in the face after all the verbal
      abuse Tesla took from Edison.

      The stories go on and on.

      Industry's attempt (obviously very successful) to purge him from the
      scientific literature had driven him into exile for nearly twenty
      years. Lacking capital, he was forced to place his untested theories
      into countless notebooks.

      The man who invented the modern world died nearly penniless at age
      86 on January 7, 1943. More than two thousand people attended his
      funeral.

      In his lifetime, Tesla received over 800 different patents. He
      probably would have exceeded Edison's record number if he wasn't
      always broke - he could afford very few patent applications during
      the last thirty years of his life.

      Unlike Edison, Tesla was an original thinker whose ideas typically
      had no precedent in science. Unfortunately, the world does not
      financially reward people of Tesla's originality. We only award
      those that take these concepts and turn them into a refined, useful
      product.

      Scientists today continue to scour through his notes. Many of his
      far flung theories are just now being proven by our top scientists.
      For example, the Tesla bladeless disk turbine engine that he
      designed, when coupled with modern materials, is proving to be among
      the most efficient motors ever designed. His 1901 patented
      experiments with cryogenic liquids and electricity provide the
      foundation for modern superconductors. He talked about experiments
      that suggested particles with fractional charges of an electron -
      something that scientists in 1977 finally discovered - quarks!

      Wow!

      Maybe history will finally recognize a true genius when it sees
      one.
