The Nikola Tesla Reminder - Google Search Image

I usually use google toolbar to search content that would be useful for me. On July 10, 2009, I notice that there was a special pattern on google search of my colleague's computer. Thus, I go to save the image on my computer with the file name started with tesla. However, I am not sure what the date is for yet.

Just google and get to know it is the birthday of Nikola Tesla (July 10, 1856 – January 7, 1943). I remembered watching a TV show about Nikola Tesla. When talking about electricity, most of us would recall Edison. Only a few common people seem to know another great inventor, Nikola Tesla for alternating current. The alternating current developed by Tesla is different from the direct current by Thomas Edison.

The alternating current power system is the fundamental system for our daily life now. The TV show presents the dispute about the experiment of Directed-energy weapon, which was based on a narrow stream of atomic clusters of liquid mercury or tungsten accelerated via high voltage. It was introduced that his experiment in 1893 for World's Columbian Exposition in Chicago made the night as bright as the day.

Thanks to Nikola Tesla, we can have the power factory far away from our house, and watch TV, open computer conveniently. Here is the information about Nikola Tesla at wikipedia: http://en.wikipedia.org/wiki/Nikola_Tesla
