INVENTIONS AND DISCOVERIES
THE FIRST TELEPHONIC MESSAGE  

In 1875, Scottish inventor Alexander Graham Bell constructed the first experimental telephone. A year later he transmitted the first telephone message to a colleague in a room upstairs. The message was as follows: Mr. Watson, come here. I want to see you.” But it was Thomas Edison who, in 1879, designed the first proper telephones, which were mounted on walls. It was only then that people could call each other between longer distances.
 
THE DAY BELL PATENTED THE PHONE

Alexander Graham Bell had invented the telephone and went to file a patent for it. On the same day another American inventor, Elisha Gray filed what was known as a ‘caveat’, for a device intended to work like the telephone. A ‘caveat’ is an intent to invent. Alexander Graham Bell’s patent went on to bring in highly lucrative returns. Did you know that laws of nature and scientific principles cannot be patented even by the one who discovers them for the first time.
 
THE INDISPENSABLE SCREW

Look at the things around you and consider just how many of these are held in place with a screw. It was Archimedes the famous Greek mathematician who invented the indispensable screw in the third century B.C. What is interesting about this invention, however, is that Archimedes did not actually devise it for the purpose it is used for today that is tightly screwing up things in place. Instead he invented as a devise for drawing up water!
 
THE MAN WHO INVENTED PHOTOGRAPHY

It was a Frenchman named Nicephore Niepce who invented photography in 1826. His search for this form of capturing images actually began in 1811 when he was trying to find a way to reproduce his son’s drawings. He conducted countless experiments. In 1816 he obtained his first image on paper that he had saturated with silver chloride. The problem? The image disappeared after some time. But the patient man that he was Nicephore did not give up. And finally in 1826 he achieved his first true photograph on a light-sensitive plate. The image appeared after 8 long hours of exposure.
 
A LEAKY LOFT AND ITS CONTRIBUTION TO MANKIND

It is a well-known fact that the Polish physicist and Nobel Prize winner Marie Curie lived and worked in penury. In fact the loft that she worked in had a constant draught that would certainly have made her very chilly and uncomfortable. However the constant draught of cold air increased her lifespan as it reduced the amount of radiation that she was inhaling from the chemicals that she used to work with. In fact Marie Curie died due to Leukemia that was brought on by her continued exposure to radioactivity. The amount of radioactivity that she was exposed to was so much that the notebooks she used are still radioactive!
 
THE ORIGINS OF THE INDISPENSABLE ERASER

British chemist Joseph Priestly had been experimenting with rubber in 1770 and he happened to chance upon its property of erasing pencil marks. Rubbing the experimental product over his etchings in pencil he discovered that there was nothing where he had rubbed. So it was christened rubber. Rubber had been in use in South America for some time, France commissioned an expedition specifically for the purpose of learning more about Rubber that visitors to South America were talking about. One such expedition in 1736 brought back crude rubber along with detailed descriptions of the way it was used in South America.
