Benjamin Franklin Lived — Benjamin Franklin lived his life in the spirit of a renaissance man: He had a profound effect on our understanding of electricity and shaped the language we use when we talk about it, even today. Here we shall concentrate on his life as a scientist and an inventor, only briefly touching on his other achievements.
His father, Josiah, was a tallow chandler, candle maker, and soap boiler who had moved to the American Colonies from England. His mother, Abiah Folger looked after the home and was the mother of ten children, including Benjamin, who was the eighth child in the family.
She was born in Nantucket, Massachusetts. Benjamin had only two years of formal education, which finished when he was ten years old, because his family could not afford the fees.
His informal education then accelerated, because his mind was too restless to stop learning. When he was twelve, Benjamin began working as an apprentice in a printing shop owned by one of his elder brothers, James. Aged 17, Benjamin Franklin left for Philadelphia, escaping from his apprenticeship, which was against the law.
He was, however, free. After a few months in Philadelphia he left for London, England, where he learned more about printing, before returning to Philadelphia at the age of 20 to continue his printing career.
Aged 27, in Decemberthe first editions of the publication that would make him a wealthy man rolled off his printing press: It was a general interest pamphlet offering interest and amusement for its readers, including: He continued reading as much as he could, increasing his knowledge of science and technology until he was in a position to begin innovating himself.
Dating his inventions is not always easy, because Franklin did not patent them. He said that anyone who wanted to make money from his ideas was free to do so. This means the dates of his inventions are approximate. Bifocal Spectacles Franklin wore spectacles for most of his life.
He felt limited by them, because any lens that was good for reading blurred his vision when he looked up. Working as a printer, this became infuriating.
He defeated the problem in aboutaged 33, with his invention of split-lens bifocal spectacles. Each lens now had two focusing distances. Looking through the bottom part of the lens was good for reading, while looking through the upper part offered good vision at a greater distance.
The Franklin Stove As Franklin read more about science, he learned more about heat transfer. He looked at the design of a typical stove and concluded that it was inefficient.
Much more heat was lost up the flue than necessary. The idea was that hot gases which would normally simply go up the flue would exchange their heat with cold air from the room, heating it up, and so heating the room up. Inthe Franklin Stove came on to the market, allowing homeowners to get more heat into their homes for each unit of fuel they burned.
Cold air blue gains heat from contact with the hot stove. As this warming air continues on its path, it gains more heat through contact with metal, the other side of which is in contact with the hot smoke red going to the flue.
The use of these fireplaces in very many houses, both of this and the neighboring colonies, has been, and is, a great saving of wood to the inhabitants. In those days, scientists were called philosophers. The Size of the Units of Matter Benjamin Franklin performed a beautiful experiment using surfactants; on a pond at Clapham Common, he poured a small amount of oleic acid, a natural surfactant which tends to form a dense film at the water-air interface.
He measured the volume required to cover all the pond. Knowing the area, he then knew the height of the film, something like three nanometers in our current units. Always seeking new knowledge, he visited a science show. There he saw Dr. Archibald Spencer, who had arrived from Scotland, demonstrating a variety of scientific phenomena.
The electrical part of the show intrigued Franklin most: Franklin left the show determined to learn more about electricity.
It seemed to him that Dr. This, of course, was true:Benjamin Franklin was born in Boston in to a father who originally intended him to enter the clergy.
Although his family could only afford to send Franklin to school for a year, he was an avid reader and soon apprenticed to his brother James, a printer. Benjamin Franklin: Inventor Benjamin had interest and talent on inventing new things.
As an inventor, he discovered bifocals, electricity, lightning nod, Franklin stove, . He is sometimes referred to as the "First American".
Franklin was a multitalented "Renaissance Man" who excelled in many areas including science, politics, writing, music, invention, and diplomacy. Where was Benjamin Franklin born?
