Franklin is famous in American history and

Scientist, politician, inventor.

New stoves, lightning rods, electric wheels, three-wheeled clocks, bifocal glasses, automatic barbecue machines, glass musical instruments, overhead book pickers, new street lights, etc.

The most representative of Franklin's invention is the lightning rod, which is a lightning protection device. The lightning rod is usually seen as consisting of three parts: a metal rod with a sharp upper end, the lower end of the metal rod is connected to a wire, and the wires are connected together on a metal plate buried in the ground.

The lightning rod is made according to the principle of tip discharge. When a conductor is electrified, the electric field near the tip is particularly strong, ionizing nearby gases, resulting in a discharge. Lightning rods serve two purposes:

First, when the cloud block is close to the lightning rod, the lightning rod can put the electricity brought by the electrostatic induction into the air and neutralize the electricity in the cloud at any time, so as to turn the violent discharge into a moderate multiple discharge and reduce the possibility of lightning strikes; The second is to act as a discharge pathway, so that electricity flows through the wires of the lightning rod without damaging the building.

Benjamin Franklin was a well-known statesman. In 1776 he took part in the drafting of the Declaration of Independence. After the independence of the United States, he went to France.

It is correct to say that Franklin was both a famous politician and a famous inventor.

Benjamin Franklin, American statesman, physicist, printer and publisher, author, inventor and scientist, and diplomat, one of the Founding Fathers of the United States.

Franklin spent his early years in the newspaper industry. The first traveling library in North America was established in Philadelphia in 1731. In 1743, he organized the American Philosophical Society, and later helped found the University of Pennsylvania.

During the American Revolutionary War, he participated in the anti-British struggle, was elected as a delegate to the Second Continental Congress, and participated in the drafting of the Declaration of Independence.

His mission to France from 1776 to 1785 led to the establishment of the Franco-American Alliance; He also negotiated with Britain on behalf of the United States and signed the Treaty of Paris in 1783, which allowed Britain to recognize the independence of the United States. In 1787, as a delegate to the Constitutional Convention, he participated in the drafting of the U.S. Constitution, advocating the abolition of slavery. He was elected a Fellow of the Royal Society for his scientific contributions.

He also served three times as governor of Pennsylvania. He died in Philadelphia in 1790 at the age of 84.

Franklin was not only a delegate to the Continental Congress and a co-signatory to the Declaration of Independence, but also a delegate to the U.S. Constitutional Convention and a signatory to the Constitution of the United States of America.

In addition, he also made outstanding contributions to scientific research: Franklin conducted a number of experiments on electricity, invented the lightning rod, and was the first to propose the law of conservation of electric charge, which contributed to the study of atmospheric electricity; Philosophically embraced deism, which recognized the existence of nature and the objectivity of its laws. French economist Durgo commented:

He took the thunder and lightning from the heavens, and the civil rights from the tyrants. "In 2006, the Atlantic magazine named him No. 6 among the 100 people who have influenced the United States.

Frank was not only a good scientist, but also a prominent social activist. He spent a lot of time in his life engaged in social activities. Franklin attached great importance to education, and he established libraries, organizations, and associations to improve the literacy of people from all walks of life.

Just as he continued to make new achievements in scientific research, the national liberation movement in the North American colonies was growing stronger due to the brutal rule of the British colonists. For the sake of national independence and liberation, he resolutely put down his experimental instruments and actively stood at the forefront of the struggle. From 1757 to 1775 he negotiated several times as a representative of the North American colonies to Britain.

After the outbreak of the Revolutionary War, he participated in the drafting of the Second Continental Congress and the Declaration of Independence.

In 1787, he took an active part in the work that created the U.S. Constitution and organized a campaign against the enslavement of blacks.

Benjamin Franklin (1706-1790) was an American industrialist, scientist, activist, thinker, and diplomat in the 18th century.

He paid attention to observing natural phenomena and studying scientific problems He proceeded from practice, engaged in scientific experiments and observations, answered the question of "what is electricity" in electricity, called electricity in different states "positive electricity" and "negative electricity", put forward the "first-class theory" in electricity, and revealed the essence of lightning phenomena in atmospheric electricity, and was known as the "second Prometheus".

He also conducted research in optics, heat, acoustics, mathematics, oceanography, botany, etc., and made a series of inventions such as new stoves, lightning rods, electric wheels, three-wheeled clocks, bifocal glasses, automatic barbecues, glass musical instruments, overhead book pickers, and new street lamps.

As a result, he was awarded a master's degree or doctorate degree by six or seven universities in the United States, including Harvard University and Yale University in the United States, and Oxford University, Edinburgh University, and St. Andrew's University in the United Kingdom.
