Thomas Edison only had 3 months of formal education, and his schoolmaster thought that Edison may have been retarded. And no one not even his family could envision that Edison would become the inventor that he would eventually end up to be. Born in Milan, Ohio, youngest of 7 children, Edison would often ask questions that his father and mother both could not answer. At 21 Edison made his commercial debut as an inventor with an electric vote-recorder. It did not sell so thereafter he decided to concentrate his efforts on inventions that he was sure would be in universal demand.
Then in 1869 Edison arrived in Boston, he persuaded a broker to let him sleep in his office. Then when the broker’s stock ticker broke Edison was able to repair it where many others had failed. Amazed the manager quickly made Edison one of his superiors. Soon, Edison had enough money to open his own workshop known as Menlo Park, it was here that some of his most important inventions were created. Of these were Modernized type writer, a practical telephone, the first working model phonograph, an incandescent light.
Eventually Edison would also design the first power station, providing electricity for millions of homes. His last contribution a synthetic rubber made from goldenrod plants. Edison patented an incredible 1093 intentions. Edison was also growing deaf due to experiments as a child, though he did not mind allowing him to concentrate more on this work. Edison died at age 84,in 1931. And I really admired the guy who was the ultimate inventor of the dynamite was named Alfred Nobel born on October 21st 1833 in Stockholm.
He studied their until1842 when his family moved to St. Petersburg in Russia. Before dynamite, miners had to use nitrogen to blow holes in rock and other things. However it is too volatile and can explode incredibly easily. Alfred changed all this. He gained interest in explosive nitroglycerin. And studied until he founded the first ever nitroglycerin factory in the world, but found it was too volatile to work with, and too many miners were dying using it. He began experimenting on how to control the substance.
He wanted something that could absorb the nitroglycerin and not still have the same power. He Found that a substance called (Kieselguhr). This way the explosive could be transported easily and detonated from a safe distance. It saved laves and time. He would name it Dynamite and got a patent for it in 1867. By his death in 1896 he had established companies in some ninety locations in twenty countries and earned over SEK 31. 5 million. It is sure that Alfred Nobel contributed a great deal to chemistry and the world and has a large diversity of achievements.
Many people will benefit from the Nobel prizes including such people as Mother Theresa and Ernest Rutherford. It is a good deed and will keep the human race alive just a little longer if people are this smart. These people are the world’s greatest inventors being unforgettable in our heart. Conclusively, many inventions or discoveries have been made to make the world better. Among all these, dynamite, computers, and most importantly, the invention of electricity are three most important inventions and discoveries that made the modern world we live in a better place.
