Necessity is the mother of invention... or is it? The real mother of invention is not necessity, but curiosity. From the discovery of electricity, the invention of the light bulb, car, airplane, and air conditioning to Global Positioning Satellite systems curiosity has been the reason behind the invention.
             One of the greatest discoveries ever was the discovery of electricity. Ben Franklin has been given the most credit for the discovery of electricity. Before the legendary kite experiment in 1752 electricity was a known force of nature, but it had not been thoroughly studied. Even after that Franklin did not know what potential his discovery of electricity had. It is said that he once tried to kill a Christmas turkey with electricity, but accidentally made contact with the current and received a nice shock. As time progressed Franklin created more and more electrical devices including the battery and the lightening rod (Thinkquest.org). These inventions were discovered through theories and hypothesis that Franklin thought might be true and he tried them and they worked. All of these things are nice, and today people probably would have difficulty living without them, but at the time in the mid-1700's people had no need for electricity.
             There is another wonderful invention called the incandescent light bulb. Thomas Edison was a professional inventor. He wanted to see if he could create a better way to light a home that with candles or lamps. And so Edison invented the incandescent light bulb. Edison tried to come out with an invention every ten days. This invention came about in October 1879 (Thomas Edison birthplace Museum). Although people wanted another way to light their homes they did a fine job by using torches and lamps. They had a want for something better, but not a need for a light bulb.
             The invention of the air conditioning unit is a very popular one here in Phoenix. This again was not a necessity; ...
