Isaac Newton Isaac Newton was born on Christmas day in 1642. He was also born premature and wasn’t expected to live. His father died three months before he was born, leaving his mother alone to raise him. His mother remarried to Barnabas Smith. He was a rather wealthy man and he forced his new wife to leave her son with his grandparents while they go live in South Witham. For everything that’s happened since his mother’s remarriage, he’s been keeping a diary explaining the hatred that he feels for his stepfather.
While he was with his grandmother he would spend the day in his room making kites and other mechanical devices. When he turned ten, his stepfather died and his mother returned to live with him. After much persuasion he decided to attend Cambridge University where all his inventions took place. He decided to figure out theory for gravity when an apple fell on his head in the summer of 1666. Being only 22 years old he was attending college. During his past years at Cambridge University, Newton had made an extraordinary breakthrough in physics and mathematics.
This mathematical genius had studied the work of every notable mathematician in the world. Also he made discoveries in the study of light. He shaped a piece of glass into what we call a prism that can split light from red to violet. He created what we now call a spectrum with cardboard and glass. When this happened he discovered that the sun produces the following colors: violet, indigo, blue, green, yellow, orange, and red.
When I was younger, in my middle school years, I would get so angry at her for being my mother. She didn’t teach me how to shave my legs; I had to learn from my best friend. Mom’s are supposed to teach their daughters how to shave their legs. Mine didn’t. When I first started wearing make-up it wasn’t because she brought me into her room and carefully showed me how to blend soft brown eye shadow ...
What he learned from this was that when looking through the prism you can no longer see the white light it becomes tinted. Newton’s discoveries in optics were quite spectacular. His discoveries explained why bodies appear to be colored. It allows people to determine the chemical composition, temperature, and even the speed of such hot, as a distant star or an object heated in a lab. He discovered that sunlight is a mixture of light of all colors. A green sweater illuminated by sunlight looks green because it reflects the green light in the sun and absorbs most of the other colors.
The study of light led him to building a new type of telescope in which a reflecting mirror is used instead of a combination of lenses. He realized that an object of the same force pulls an object to earth and keeps the moon in its orbit. The force by which the earth attracts or pulls a large rock is greater than the pull on a small pebble because the rock contains more matter. The earth’s pull is called the weight of the body. This theory helped explain why a rock weighs more than a pebble. He also proved that many types of motion are because of one kind of force.
He showed that the gravitational force of the sun keeps the planets in their orbits, just as the gravitational force of the earth attracts the moon. The falling of objects on earth seems different from the motion of the moon because the objects fall straight down to the earth. The moon moves in a circle around the earth. He showed that the moon falls just like an object on earth. Newton calculated how much the moon falls in each second. The moon is 60 times as far from the earth’s center as any other object.
Now you understand how an apple can change the world.
