Benjamin Franklin, we all have heard this name at least once in our lives. But who is he? Well, I can start by saying that he was one of the greatest minds involved in the American Revolution. He was a politician, inventor, statesman, postmaster, satirist and a diplomat. And in everyone of this fields he did a great job. He was a great figure in the enlightenment for his many inventions from which we can say that the discovery of electricity is the best. He was also known as The First American because of his great campaign for colonial unity. For all this and more he is a great man who is worthy of remembering.
Benjamin Franklin was a geat inventor. He invented the lightnig rod, the stove, the glass harmonica, bifocal glasses and the flexible urinary catheter. A lightning rod is amethalic rod or condunctor placed in the highest part of an edificatio to protect it from lightnigs during electrical storms. This rod is conected to another rod that is underground by a cable, in this way the electric shock is absorbed by the ground and it doesn´t hit the edification. Franklin´s stove consist of a metalic fireplace that was intended to rlease less smoke and more heat. Bifocals are a kind of glasses with two distinct optical powers. The glass armonica is an instrument that uses glass bowls or goblets that are graduated in size to produce distinct musical notes by friction. A urinary catheter is a plastic tube that is gently slid into the patient´s urethra and to the bladder to allow freely expulsion of urine or to inject medicine direct to the bladder. However in Franklin´s time they were not flexibble making the process of cathering very painful.
