Isaac Newton, scientist and mathematician

by Nyein Chan

Isaac Newton was a scientist and mathematician. He was born in 1642. He invented calculus, a form of math. He also created the theory of color.     People use to think that red was closest to white and blue was closest to  black. They thought of color as a change in amplitude of light waves but Newton discovered that color has to do with change in frequency in when he made white light pass through a triangular prism. When the white light  passed through the prism, a rainbow was created.

When an apple fell on Newton’s head, he got the idea that the force that made the apple fall to the ground is the same force that keeps the earth orbiting the sun. The incident led to his three laws of physics:

*”A body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force.” Newton’s first law is often referred to as the law of inertia.

*”Force equals mass times acceleration (F=ma).” The net force on an object is equal to the mass of the object multiplied by its acceleration.

*”To every action there is an equal and opposite force.”

Newton did not have much interest in any subject except for math, science, and social science. He worked at Cambridge University to earn the money he needed to attend the university because he barely had any money. To save money, he sometimes had to eat the leftovers of other students. He did not receive any awards at Cambridge and was not considered an outstanding student by most of his teachers. After the university temporarily shut down, Newton did many experiments and took notes. When he invented calculus and discovered the basic laws of physics, he was only in his twenties but he did not publish his discoveries until he was in his forties. An astronomer, Edmund Halley forced him to publish his discoveries. Newton accused another man who also invented calculus for copying his work. Two hundred years later, both men were said to have invented calculus.

Newton’s most famous discovery was the Universal Law of Gravitation: gf=G(m*m/r*r).This formula is used to figure out the gravitational force between two objects.

Isaac Newton died in 1727. Some people think that his life was shortened from dealing with mercury in his experiments.

Isaac Newton, a great scientist

by Will

Isaac Newton is considerd one of the greater scientists for his for his work on universal gravitation, the laws of motion, calculus, and a light theory.

Isaac Newton was born in 1643 at a English town called Woolsthorpe. When he was young he was in a very poorly operated school. In the school it was said that Isaac was hit on the head somehow and “the hard shell which imprisoned his genius was cracked wide open.” He started to ask questions like “What is light and how is it transmitted? What keeps the moon in the orbit of the earth, and the planets in the orbit of the sun? Why does the apple fall to the ground?” When he became a grown man he answered these questions and came up with proof that his claims were true.

Isaac Newton died at March 20th 1727. He died a knight of Queen Elizabeth, a master of the mint, a president of the Royal Society, and one of England’s greats.

Sally K. Ride

by Lauren

Sally K. Ride was born May 26, 1951 in Los Angeles CA. She was selected as an astronaut candidate in January of 1978 by NASA. Dr. Ride went on many missions and served as an on-orbit capsule communicator on the STS-2 and STS-3 missions. Dr. Ride has written five books for children on space as well. Sally K. Ride was an outstanding astronaut and won countless awards. “She has been inducted into the National Women’s Hall of Fame and the Astronaut Hall of Fame, and has received the Jefferson Award for Public Service, the von Braun Award, the Lindbergh Eagle, and the NCAA’s Theodore Roosevelt Award. She has also twice been awarded the NASA Space Flight Medal.” Said on the website Dr. Sally K. Ride was one of the many people who risked their lives to help us understand outer space.

Galileo was a famous scientist born in 1564, and he made many great contributions to the world of astronomy. Some of his famous discoveries were the phases of Venus, the four largest moons of Jupiter, and sunspots. However, when he spoke his mind that the earth rotated around the sun, already said by Copernicus, he was protested against. When he published his beliefs in a book, in 1616, he was tried and put in house arrest for the rest of his life.

The Life of Rachel Carson

by Hannah

Rachel Carson was a writer, scientist, and ecologist. She was born on May

27, 1907 in Springdale, Pennsylvania. She had a life-long love of the living

world and nature itself. Rachel graduated from the Pennsylvania College for

Women, which is now known as Chatam College, in 1929. Then she got her

Master’s Degree in zoology from John Hopkins University in 1932.

She then wrote pamphlets on natural resources and she edited scientific

articles. She wrote a book called Under the Sea-Wind and had it published

in 1941. She then also wrote a book called The Sea Around Us in 1952,

which was followed by The Edge of the Sea in 1955. She wrote many other

books after that. At that point she was famous as a naturalist and a science


Carson challenged the practices of some scientists and the government. She

was then confronted by the chemical industry and the government. But she

wasn’t scared. In 1964 she testified before Congress for new policies to

protect human health and the envoirment. Rachel Carson died on April 14,

1964 in Silver Spring, Maryland after a long fight against breast cancer.

She once said, “Those who contemplate the beauty of the earth find

resources of strength that will endure as long as life lasts.” I like this

quote because it shows how she thought of the earth, and it explained her

actions well.
