What kind of scientist was Franklin and which ones did Franklin invent

Is this what you want?

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

He was the first scientist and inventor in American history to achieve international fame. In order to explore electricity, he has made the famous "kite experiment", and has made remarkable achievements in electricity, and in order to deepen the law of electric motion, many special terms such as positive electricity, negative electricity, conductive body, battery, charge, discharge, etc. have become common words in the world. He borrowed the mathematical concept of positive and negative, and the first to scientifically use the concepts of positive and negative electricity to represent the properties of electric charges.

He also put forward the idea that electric charges cannot be created or destroyed, and later generations discovered the law of conservation of electric charges on this basis. He was the first to put forward the idea of lightning rods, and the lightning rods created from this avoided lightning disasters and broke superstitions. He was a good politician and a veteran of the American Revolutionary War.

He participated in the drafting of the Declaration of Independence and the U.S. Constitution, and actively advocated flying out of slavery, which was deeply revered by the American people. It also enjoys a high reputation in the world.

The greatest American scientist and inventor of the eighteenth century, a famous statesman, diplomat, philosopher, writer and navigator, and the great leader of the American Revolutionary War.

Benjamin. Benjamin Franklin (1706-1790) is the most perfect representative of the capitalist spirit, the greatest American scientist and inventor of the eighteenth century, a famous statesman, diplomat, philosopher, writer and navigator, and a great leader of the American Revolution. The truest portrayal of his life is a sentence he himself once said: "Honesty and diligence should be your permanent companion." ”

There are scientists, there are politicians.

There are many people with the same surname.

Benjamin Franklin

Franklin (January 17, 1706 – April 17, 1790) was born in Boston, Massachusetts, USA, and was not only a famous American politician and physicist. He was also a publisher, a printer, a journalist, an author, a philanthropist, and a distinguished diplomat and inventor. So what did Franklin invent?

1. Lightning rods: Franklin is famous for his experiments with electricity, he is best known for his kite experiments, in 1952 Franklin risked being struck by lightning, began to do lightning experiments, and by 1749, he turned his attention to the possibility of protecting buildings and residents from lightning strikes. He noticed that a sharp iron needle conducts electricity out of the charged metal sphere, which is the predecessor of the lightning rod.

2. Bifocals: Like most of us, Franklin found that his eyesight got worse as he got older, and his nearsightedness and farsightedness got closer. Tired of switching between two pairs of glasses, he invented bifocals, or what we now call double glasses.

He used two pairs of glasses, one for reading and one for distance, to cut the lenses in half from horizontal and remade them into a pair.

3. Swim fins: An avid swimmer, Franklin was only 11 years old when he invented swim fins, which are two oval-shaped pieces of wood that, when held in his hand, provide extra thrust in the water.

4. Urinary catheter: In 1752, Franklin was inspired to invent a better catheter, when he saw his younger brother suffering from kidney and bladder stones, so Franklin devised a better solution: a flexible catheter consisting of hinged connected tubes.

This is the original urinary catheter.

1. Propose the law of conservation of electric charge

Franklin believed that every object has a certain amount of electricity, and that there is only one type of electricity. Friction cannot create electricity, it just transfers electricity from one object to another, and their total charge remains the same. The excess charge on the object is called positively charged, and the insufficient charge is called negatively charged.

Thanks to the introduction of these concepts, electricity has become a physical quantity that can be quantified.

2. Lightning rods were made

In 1752, he carried out an experiment with electric kites in Philadelphia that shook the world: in the case of thunder and lightning, the kite was used to collect atmospheric electricity into a Leyden bottle and recharge it, thus proving his idea of "the identity of lightning and static electricity".

Based on this theory and his discovery of the phenomenon of the discharge of the tip grounding conductor, in 1750 a proposal was made for lightning rods. This suggestion was first applied in 1852 at the University of Marley, France. The invention of the lightning rod not only prevented the serious harm caused by lightning, but also dispelled superstition and revealed the true nature of natural forces.

Benjamin Franklin was an American preeminent politician, scientist, thinker, and essayist known as the Father of America. Next, I will tell you how he became self-taught, and I hope that reading it will bring you some motivation and some inspiration for your life.

What opportunities does a poor child have to develop his talents? In a land still dominated by countries across the ocean, there are even fewer opportunities. Franklin grew up and lived in what would become a young colony of the United States.

During his lifetime, he witnessed and influenced the development of the British colonies.

Perhaps the most important thing that sets Franklin apart is his desire to know everything. He left school when he was ten years old. But in the decades that followed, he continued to learn.

For him, books are priceless; Books are the key to happiness and success. Reading enabled the young Franklin to master his writing skills, logical reasoning, and to defend his beliefs firmly.

At the age of 17, he left Boston for Philadelphia, where diligence and good fortune earned the penniless young printer a decent position.

He cared about public service, and in this regard, his influence was immeasurable. When the country needed a spokesperson, Franklin was able to speak on behalf of the country. He helped the colony gain freedom and establish a new state. In the eyes of European monarchs, he represented his country.

His scientific work was honored in France and England. His achievements are recognized throughout Europe. Boys who drop out of school at a young age discover the principle of electricity and invent many things. These inventions are still benefiting humanity today.

He is not only good at solving special problems in the natural sciences and practical problems in socio-political activities, but also often explores many philosophical and social problems.

He actively participated in the revolutionary movement and made a great contribution to the victory of the American Revolutionary War and the initial construction of the American state system. The truest portrayal of his life is his own words, "Honesty and diligence should be your eternal companion." ”

Because Franklin had only been a student for a few years, he was a great reader, taught himself to read and write, and later became a famous scientist, inventor, politician, diplomat, and one of the most talented people in the early United States.

Because of Franklin's personal diploma, he reached the stage of elementary school, but through his own efforts and studies, he became a very famous scientist, and a very great political scientist in American history.

He has been very fond of reading since he was a child, and he has gained a lot of knowledge from books, which has also stimulated his enthusiasm for learning. All of his achievements were self-taught.
