The well-known Newtonian laws of motion are: 1 an object at rest tends to stay at rest and an object in uniform motion tends to stay in uniform motion unless acted upon by a net external force. In a story that has long since gone into the public consciousness, Newton supposedly found inspiration for his theory of gravitation upon seeing an apple fall from a tree. From this he conjectured that gravity's pull could extend outwards from the earth, even as far as the moon and further.
Newton's achievements have been celebrated in many ways, with statues and poems. Notably the unit for force was named for him, the newton N. Dutch astronomer Christiaan Huygens — made advances in mathematics, physics, and horology. Developing improved telescopes, he was able to make several important astronomical discoveries. In , he proposed that a thin, flat ring circled Saturn. He also discovered the first moon of Saturn, Titan.
He made the first known drawing of the Orion Nebula. Elsewhere in his research, Huygens proposed a wave theory of light, which was disputed by Newton, who preferred the particle theory. The modern theory of light combines the two into a wave-particle duality model. Recently, Huygens' legacy was commemorated in the probe named after him, which parachuted on Titan in In , Cassini and colleague Jean Richer used the parallax method to determine the distance of Mars from Earth, permitting the first estimations of the dimensions of the solar system.
Using a method outlined by Galileo, Cassini was also the first to make successful measurements of longitude. In addition, he discovered the Cassini Division in the rings of Saturn in His name lives on today in the Cassini orbiter which has studied Saturn and its satellites since Charles Messier of France developed an interest in astronomy at an early age, having witnessed a 6-tailed comet at age 14 in Further he viewed an annular solar eclipse in As a young comet hunter, he began to discover and note nebulas, as these frequently were confused for comets.
Thus began his famous catalog of deep-sky objects, such as star clusters and galaxies. The first version in covered 45 objects, eventually expanded by Messier to objects though there is a debate about M Later astronomers filled out the catalog to a total of objects. Today Messier's catalog is still used widely, though because of his location in France, he only included Northern Hemisphere sky objects. Albert Einstein — of Germany stands as the preeminent physicist of the twentieth century. Though he did not practice observational astronomy as in peering through telescopes, his theories of relativity extended so far — to the entire universe, in fact — they forever changed astronomy. Further, the speed of light is a constant.
A great deal of modern physics revolves around these ideas. Further expanding those ideas, Einstein developed general relativity, which states space and time curve near a massive object, distorting the fabric of space-time. Einstein received the Nobel Prize in physics, among many other awards and honors. His distinctive appearance, in particular his flowing hair, made an indelible impression upon world society, serving as a template for eccentric scientists and geniuses in fiction. Carl Sagan , was born in Brooklyn, New York.
He served as professor of astronomy and space sciences, and director of the Laboratory for Planetary Studies at Cornell University. In the Principia, Newton explained three basic laws that govern the way objects move. He then described his idea, or theory, about gravity. Gravity is the force that causes things to fall down. If a pencil fell off a desk, it will land on the floor, not the ceiling. In his book Newton also used his laws to show that the planets revolve around the suns in orbits that are oval, not round. Newton also discovered diffraction. This led him to enter the field of physics, where he prospered. When most people think of Isaac Newton, they think of him sitting under an apple tree watching an apple fall.
Some people even believe the apple fell onto his head. Newton understood that what makes things like apples fall to the ground is a specific kind of force — the force we call gravity. Newton thought that gravity was the force of attraction between two objects, such as an apple and the earth. He also thought that an object with more matter exerted the same force on smaller objects as they exerted on it. That meant that the large mass of the earth pulled objects toward it.
That is why the apple fell down instead of up, and why people do not float in the air. Isaac Newton went on thinking about gravity. Before Newton, people thought that only objects near to the earth would fall down. But Newton thought that gravity should not just be limited to the earth and the objects on it. What if gravity went to the moon and beyond?
Newton invented a formula for calculating the force of attraction between two bodies. He used it to calculate the force needed to keep the moon moving around the earth. Then he compared it with the force that made the apple fall downward. After allowing for the fact that the moon is much farther from the earth, and has a much greater mass, he discovered that the forces were the same. The formula invented by Newton is called the Law of gravitation. No one had been able to explain why the planets stayed in their orbits. What held them up? Less than 50 years before Isaac Newton was born it was thought that the planets were held in place by an invisible shield.
He also showed that the force of gravity was affected by distance and by mass. He was not the first to understand that the orbit of a planet was not circular, but more elongated, like an oval. What he did was to explain how it worked. Isaac Newton was the first to discover the laws of gravitation and the laws of motion. He also established a new field in mathematics known as calculus , though the German Gottfried Leibniz had developed the ideas at the same time. His work has greatly contributed in the areas of science and mathematics making him one of the most influential scientists in human history and one of the greatest mathematician of all times.
The great physicist, Albert Einstein , thought that Newton's idea of gravity was not completely accurate. He corrected many of the things that Newton did. Isaac Newton died on 31 March [ O. He is buried in Westminster Abbey. From Simple English Wikipedia, the free encyclopedia.
