ISaac newton .One of history ‘s greatest scientists
This is Shirley Griffith and this is Steve Ember with the VOA special English program explorations
Today we tell about one of the world greatest scientists
Isaac Newton
Much of today ‘s science of physics is based on Newton ‘s discovery of the three laws of motion and his theory of Gravity.Newton also developed one of most powerful tools of mathematics .It is the method we call calculates.Late in his life, Newton said of his work:” if I saw further than other men ,it was because I stood on the shoulder of giants”
One of those giants was the great Italian scientist,Galileo.Galileo died the same year Newton was born.Another of the sciences was Polish scientist Nicolas Copernicus.He lived a hundred years before Newton.Copernicus had began a scientific revolution. It led too a completely new unsderstanding of how the universe worked.Galileo continued and expanded the work of Copernicus.Isaac Newton built on the ideas of these to scientist and others.He found and improved the answeres for which they searched.
Issac Newton was born in Woolsthorpe England ,on December twenty fifth sixteen forty two(1640).He was born early.He was a small baby and very weak.No one expected him to survive .But he surprised everyone.He had one of the most powerful minds in history .And he lived until he was eightyfour .Newton ‘s father died before he was born.His mother married again a few years late.She left Isaac with his grandmother.
The boy was not a good student.Yet he liked to make things,sush as kites… and clocks and simple machines.
Newton also enjoyed finding new ways to answer questions or solve proplems.As a boy,for example he dicided to find a way to measure the speed of the wind.On the windy day he measured how far he could jump with the wind in his back.Then he measured how far he could jump with the wind in his face.From the difference between the two jumps he made his own measure of the strength of the wind.
Strangely Newtom became a much better student after a boy kicked him in the stomach The boy was one of the best student in the school.Newton decided to get even by getting higher marks than the boy who kicked him.In a short time,Newton became the top student at the school.
Newton left school to help on the family ‘s farm.It soon became clear however that the boy was not a good farmer.He spent his time solving mathematical proplem instead of taking care of the crops.He spent hours visiting a book store In town , instead of selling his vegetables in the market.An uncle decided that Newton would do better as student than as farmer .So he help the
young man enter Cambrige University to study mathematics . Newton completed his university studies five years later.In sixteen sixty –five (1665),he was twenty two years old.
At that time' a deadly plague was spreading across England.To escape the deceases Newton returned to the family ’s farm.He did more thinking than farming.In during so he found the answers to same of the greatest mysteries of science
Newton used his great skill in mathematic to form a better understanding of the world and the universe.He used methods he had learned as a boy in making things ,he experimented .Then he studied the results and used what he had lend to design new experiments.
Newton’ s work led him to create a new method in mathematic for measuring things areas curved in shape.He also used it to find how much material was contained in solid objects .The method he created became known as integral calculates
One day,sitting in the garden,Newton watched an apple fall from a tree,he began to wonder if the same force that pulled the apple down also kept the moon circling the earth.Newton believed it was and he believed it cut be measured.He called the force ‘s Gravity He began to examine it carefully.He decided that the strength of the force, keeping the planet in orbit around the sun ,depended on too things.One was the amount of mass in the planet and the sun .The other ways how far apart they were.
Newton was able to find the exactly relationship between distance and gravity.He multiplied the mass of one space object by the mass of the other.Then he divided that number by the square of their distance apart.The result was the strength of the gravity force that tided them to each other.
Newton proved his idea by measuring how much gravity force would be needed to keep the moon orbiting the earth.Then he measured the mass of the earth and the moon,and the distance between them.He found that his measurement of the gravity force produced was not the same as the force needed.But the numbers were close
Newton did not tell anyone about his discovery.He put it a side to work on other ideas.Later with correct measurement of the size of the earth,he found that the number was exactly the same.
Newton spent time studying lite and colors,He used a three sided peace of glass called a prism…
He sent a beam of sunlight through the prism It fell on a white surface.The prism separated the beam of sunlight into the color of a rainbow .Newton believed that all these colors mixed together in lightproduced the colors white.He proved these by letting the beam of rainbowcolored light pass through:another prism.This changed the colored light back to white light
Newton ‘s study of light led him to learn why far away objects seen through a telescope do not seem sharp and clear.The covered glass lenses at each and of the telescope acted like prisms.They produced a circle of colored light around an object.This created on unclear picture.A few years later,Newton built a different kind of telescope.It used a coverd mirror to make far away objects seem large.Lite reflected from the surface of the mirror,instead of passing through a covered lens.Newton reflecting telescope produced much clearer pictures than the old kind of telescope
Years later ,the British astronomer Edmund Halley visited Newton.He said he wanted Newton help in finding an answer to a problem no one had been able to solve.The question was this :What is the path of a planet going around the sun?Newton immediately gave Halley the answer:an eggshaped path called an ellipse
Halley was surprised.He asked for Newton ‘s proof.Newton no longer had the papers from his earlier work.He was able to recreate them,howeverHe showed them to Halley.He also showed Halley all his other scientific works
Halley said Newton ‘s scientific discoveries were greatest ever made .He urged Newton to share them with the world. Newton began to write a book that explained what he had done.It was publish in sixteen eighty seven(1687)Newton called his book “ The mathematical principles of natural philosophy.”The book is considered the greatest scientific work ever written
In his bookNewton explained three natural laws of motion.The first law is that an object not moving remains still.And one that is moving continues to move at an unchanging speed,show long as no outside force influences it. Objects in space continue to move ,because nothing exist in space to stop them .Newton’s second law of motion describes force.It says force equals the mass of an object multiplyed by the change in speed it produces in an object.His third law says that force every action, there is an equal and opposite reflection
From these three laws,Newton was able to show how the universe worked.He proved it with easily understood mathematics.Scientist everywhere accepted Newton’s ideas .The leading English powered of Newton’s time. Alexander Pope honoured the scientist with these words:”Nature and nature’s force lay hɪd in night.God said “let Newton bee –and always light “

Thank you for your help to correct this test.If It is still where wrong ,repair please it.

New year's test answer.
Happy new year to miss Maroon and all mates.
I'm sorry for not doing the 1st part because i was really busy (maybe lazy). However, the test is too difficult and too long for me. It shows how much time and efford you spent to prepare it. Thank you a lot miss Maroon.

ISAAC NEWTON, ONE OF HISTORY'S GREATEST SCIENTIST.
This is Sherley Griffith. And This is Steve Ember with the VOA special English program, explorations. Today we tell about one of the world's greatest scientist, Isaac Newton.
Much of today's science of physics is based on Newton's discovery of the three laws of motion and his theory of gravity. Newton also developed one of the most powerful tools of mathematics. It is the method we call calculus. Later in his life, Newton said of his work: " if i saw further than other men, it was because i stood on the shoulders of giants.
One of those giants was the great Italian scientist, Galileo. Galileo died the same year Newton was born. Another of the giants was the Polish scientist Nicholas Copernicus. He lived a hundred years before Newton. Copernicus had began a scientific revolution. It led to a completely new understanding of how the universe worked. Galileo continued and expanded the work of Copernicus. Isaac Newton built on this ideas of these two scientists and others. He found and proved the answers for which they searched.
Isaac Newton was born in Woolsthope, England, on December twentyfifth, sixteen forty two. He was born early. He was a small baby and very weak. No one to expected him to survive. But he surprised everyone. He had one of the most powerful minds in history. And he lived until he was 84. Newton's father died before he was born. His mother married again a few years later. She left Isaac with his grandmother.
The boy was not a good student. Yet he liked to make things, such as kites and clocks and simple machines.
Newton also enjoyed finding new ways to answer questions or solve problems. As a boy, for example, he decided to find a way to measure the speed of the wind. On a windy day, he measured how far he could jump with the wind at his back. Then he measured how far he could jump with wind in his face. From the difference between the two jumps, he made his own measure of the strength of the wind.
Strangely, Newton became a much better student after a boy kicked him in the stomach. The boy was one of the best students in the school. Newton decided to get even by getting higher marks than the boy who kicked him. In a short time, Newton became the top student at the school.
Newton left school to help on the family farm. It soon became clear, however, that the boy was not a good farmer. He spent his time solving mathematical problems, instead of taking care of the crops. He spent hours visiting a book store in town, instead of selling his vegetables in the market. An Uncle decided that Newton would do better as a student than as (?) a farmer. So he helped the young man enter Cambridge University to study mathematics. Newton completed his university studies five years later, in 1665. He was 22 years old.
At that time, a deadly plague was spreading acrross England. To escape the disease, Newton returned to the family farm. He did more thingking than farming. In doing so, he found the answers to some of the greatest misteries of science. Newton used his great skill in mathematics to form a better understanding of the world and the universe. He used methods he had learned as a boy in making things. He experimented. Then he studied the results and used what he had learn to design new experiments.
Newton's work led him to create a new method in mathematics for measuring areas curved in shape. He also used it to find how much material was contained in solid objects. The method he created became known as integral calculus.
One day, sitting in the garden, Newton watched an apple fall from a tree. He began to wonder if the same force that pulled the apple down also kept the moon circling the earth. Newton believed it was. And he believed it could be measured. He called the force "gravity". He began to examine it carefully. He decided that the strength of the force keeping a planet in orbit around the sun depended on two things. One was the amount of mass in the planet and the sun. The other was how far apart they were.
Newton was able to find the exact relationship between distance and gravity. He multiplied the mass of one space object by the mass of the other. Then he divided that number by the square of the distance apart. The result was the strength of the gravity force that tied them to each other.
Newton proved his idea by measuring how much gravity force would be needed to keep the moon orbiting the earth. Then he measured the mass of the earth and the moon and the distance between them. He found that his measurement of gravity force produced was not the same as the force needed. But the numbers were close.
Newton did not tell anyone about his discovery. He put it aside to work on other ideas. Later, with correct measurements of the size of the earth, he found that the numbers were exactly the same.
Newton spent time studying light and colours. He used a threesided piece of glass called a prism.
He sent a beam of sunlight through the prism. It fell on a white surface. The prism separated the beam of sunlight into the colour of a rainbow. Newton believed that all these colours  mixed together in light  produced the colour white. He proved this by letting the beam of rainbow  coloured light pass through another prism. This changed the coloured light back to white light.
Newton's study of light led him to learn why faraway objects seen through a telescope do not seem sharp and clear. The curved glass lenses at each end of the telescope acted like prisms. They produced a circle of coloured light around an object. This created an unclear picture. A few years later, Newton built a different kind of telescope. It used a curved mirror to make faraway objects seem larger. Light reflected from the surface of the mirror, instead of passing through a curved glass lense. Newton reflecting telescope produced much clearer pictures than the old kind of telescope.
Years later, the Bristish astronomer Edmund Halley visited Newton. He said he wanted Newton help in finding an answer to a problem no one had been able to solve. The question was this: What is the path of a planet going around the sun?. Newton immediately gave Halley the answer: an eegshape path called an elipse.
Halley was surprised. He asked for Newton's proof. Newton no longer had the paper from his early work. He was able to recreate them, however. He showed them to Halley. He also showed Halley all his other scientific work.
Halley said Newton's scientific discoveries were the greatest ever made. He urged Newton to share them with the world. Newton began to write a book that explained what he had done. It was published in 1687. Newton called his book: "The mathematical prnciples of natural philosophy". The book is considered the greatest scientific work ever written.
In his book, Newton explains the three natural laws of motion. The first law is that an object not moving remains still. And one that is moving continues to move at an unchanging speed, so long as no outside force influences it. Objects in space continue to move, because nothing exits in space to stop them.
Newton second law of motin discribes force. It says force equals the mass of an object, multiplied by the change in speed it produces in an object. His third law says that for every action, there is an equaland opposite reaction.
From these three laws, Newton was able to show how the universe worked. He proved it with easily understood mathematics. Scientists everywhere accepted Newton's ideas. The leading English poet of Newton's time, Alexander Pope, honouned the scientist with these words: "nature and nature's laws lay hid in night. God said: 'Let Newton be'  and all was light".

Isaac Newton, one of history's greatest scientists
This is Shirley Griffith.
And this is Steve Ember with the VOA special English program, explorations. Today we tell about one of the world's greatest scientists, Isaac Newton.
Much of today's science of physics is based on Newton's discovery of the three laws of motion and his theory of gravity. Newton also developed one of the most powerful tools of mathematics. It is the method we call calculus. Late in his life, Newton said of his work : " If I saw further than other men, it was because I stood on the shoulders of giants."
One of those giants was the great Italian scientist, Galileo. Galileo died the same year Newton was born. Another of the giants was the Polish scientist Nicholas Copernicus. He lived a hundred years before Newton. Copernicus had begun a scientific revolution. It led to a completely new understanding of how the universe worked. Galileo continued and expanded the work of Copernicus. Isaac Newton built on the ideas of these two scientists and others. He found and proved the answers for which they searched.
Isaac Newton was born in Woolsthorpe, England on December 25th, 1642. He was born early. He was a small baby and very weak. No one expected him to survive. But he surprised everyone. He had one of the most powerful minds in history. And he lived until he was 84. Newton's father died before he was born. His mother married again a few years later. She left Isaac with his grandmother.
The boy was not a good student. Yet(nó có nghĩa là gì vậy cô) he liked to make things, such as kites and clocks and simple machines.
Newton also enjoyed finding new ways to answer questions or solve problems. As a boy, for example, he decided to find a way to measure the speed of the wind. On a windy day, he measured how far he could jump with the wind at his back. Then he measured how far he could jump with the wind in his face. From the difference between the two jumps, he made his own measure of the strength of the wind.
