Essay #25 History Of Inventions

Hello, in today’s lesson I will be talking about Christian Hawkins, calculus, Anton van Leeuwenhoek, and Isaac Newton. I hope you will enjoy.

Christian Huygens

Christian Huygens was born in 1629 in the Dutch Republic, he had a scientific education. He published his first book when he was 22 years old. He discovered the rings of Saturn, he also invented the pendulum clock and 1656. He propose the wave theory of light in 1678, and invented the magic lantern in 1659. He was a friendly and likable man, meaning that he was a good friend in other words. I would say the Christian Huygens made many discoveries and inventions over his lifetime, because Massa even sent up a rocket called Huygens.


Calculus means a small pebble, it is a mathematical study of change. Calculus explains music and motion, it even predicts radioactive decay. Calculus really multiplied by the end of the 18th century, people were using it more. You can use calculus to find out the area of a curve, or to find out how close to dots are on a curve.

Anthony van Leeuwenhoek

Anthony van Leeuwenhoek did not go to college, he had an interest in quality cloth, so he investigated the quality of cloth. To do this most people use the magnifying glasses and were trained to tell if it’s good or bad wolf, but Anthony van Leeuwenhoek made his own lenses, he is mostly known for his microscopic discoveries. He made his own microscope as you could most likely already tell, but he discovered microorganisms, unfortunately he never really published a book because he did not know how to write in other languages besides Dutch. But he wrote hundreds of letters. And that is how his discoveries got known.

Isaac newton

Isaac newton was born in 1642 and died in 1727, he studied natural philosophy, he rote an important book called the Principia in 1687, the law of motion. Add say that his greatest discovery was the gravitational force. Because with his discovery of the gravitational pool helped us go to the moon. He also said that an object in motion tends to stay in motion. Also he studied light, he said that White light is multiple colors when it goes through a prism. He also invented the first reflection telescope. For25 years of his life he was the president of the Royal society and governed it with an iron fist. Very iron fist. Meaning that he would tell them to promote his work but with that they must respect him.

Thank you for reading this essay about Christian Hawkins, Calculus, Anton van Leeuwenhoek, and Isaac Newton, I hope you enjoyed, would you like to tell me what you learned about in this lesson. Bye and see you next time.
