The first prism split the white light into different colors, but the second prism recombined the colors into white light once again! He also was able to shine lights of just one color onto a second prism and found that those colors did not change (red still was red blue still was blue), showing again that prisms did not change the color of white light, it just separated the different colors within it.
He then allowed the light to shine through two prisms. His experiment involved making a hole in the window shutters for light to shine through. During his time in Woolsthorpe Manor, he discovered that white light is made up of every color of light. Newton wasn’t satisfied with just thinking about gravity or mathematics he was also very interested in light. Fun fact: The apple tree still grows in Woolsthorpe Manor!ĭuring this time Newton also developed calculus, which he called fluxions. It states that all objects (whether they are on earth or in outer space) are attracted to each other by gravity and lays out a formula to calculate the gravitational force between objects. This law mathematically shows how gravity is holding the universe together.
This eventually led to Newton’s law of universal gravitation (published in 1687). This in turn, made him think that the force that pulls an apple to the ground might be the same force that governs the moon’s attraction to Earth and, therefore, keeps the moon in its orbit. While an apple probably did not fall on his head, Newton does recall seeing an apple fall from an apple tree in Woolsthorpe Manor which led him to think about why an apple falls straight to the ground (as opposed to up or sideways). You have probably heard of the story of the apple that fell on Newton’s head and caused him to think about gravity. Newton’s period of his life while he was away from Trinity College in his family’s estate is referred to as his “Year of Wonders” because of the amazing breakthroughs and insights he made during that time, which laid the groundwork for modern physics. Newton then withdrew to his childhood home, Woolsthorpe Manor, 60 miles away from Cambridge, and so began what is known as his “Year of Wonders.” In 1665, Newton was at Cambridge University’s Trinity College, having just finished his bachelor’s degree, when the school closed down its doors in response to the plague. The Great Plague devastated the city of London, with around 15% of London’s population losing their lives. It was caused by the bacterium Yersinia pestis, which was also the source of the Black Death in the 14th century. The Great Plague of 1665-1666 was an epidemic that started in a London parish called St Giles-in-the-Fields and quickly spread. What some may not know is that he made major breakthroughs in these areas while practicing social distancing during the Great Plague that spread in England in 1665. He is famous for his discoveries in the fields of motion, gravity, optics, and mathematics. Sir Isaac Newton (January 4, 1643-March 31, 1727) was an English physicist and mathematician. However, Isaac Newton proves that time spent in social isolation can lead to great insights. Without our normal routine, it might feel like we are not accomplishing much. As we are practicing social distancing during this time, it is easy to feel restless.
