How Isaac Newton Changed Our World

Known as refracting telescopes, they used glass lenses that changed the direction of different colors at different angles. This caused “chromatic aberrations,” or fuzzy, out-of-focus areas around objects being viewed through the telescope. After much tinkering and testing, including grinding his own lenses, Newton found a solution. He replaced the refracting lenses with mirrored ones, including a large, concave mirror to show the primary image and a smaller, flat, reflecting one, to display that image to the eye. Newton’s new “reflecting telescope” was more powerful than previous versions, and because he used the small mirror to bounce the image to the eye, he could build a much smaller, more practical telescope. In fact, his first model, which he built in 1668 and donated to England’s Royal Society, was just six inches long (some 10 times smaller than other telescopes of the era), but could magnify objects by 40x. Newton’s simple telescope design is still used today, by both backyard astronomers and NASA scientists.

Where Did Physics Originate?

Contents • What is origin according to physics? • Who is the father of physics? • When did physics started? • When did physics come of age? • Is physics a science or math? • How did life start? • Why physics is the most basic science? • Was physics invented or discovered? • Who invented gravity before Newton? • What was physics before Newton? • Is physics really a science? • Which comes first physics or technology? • Is physics the same everywhere? • Who were the first humans? • Where do the first humans come from? • How was the universe created? • What is the toughest subject? • What is the hardest type of math? • What is a golden age in the history of science? • When did American physics come to the forefront? Isaac Newton is popularly remembered as the man who saw an apple fall from a tree, and was inspired to invent the theory of gravity. If you have grappled with elementary physics then you know that he invented calculus and the three laws of motion upon which all of mechanics is based. What is origin according to physics? A point from which a body or an object starts moving is said to be origin of motion of the body. Who is the father of physics? Galileo Galilei pioneered the experimental scientific method and was the first to use a refracting telescope to make important astronomical discoveries. He is often referred to as the “father of modern astronomy” and the “father of modern physics”. Albert Einstein called Galileo the “father of modern science.” When did physi...

Newton's apple: The real story

We’ve all heard the story. A young Isaac Newton is sitting beneath an apple tree contemplating the mysterious universe. Suddenly – boink! -an apple hits him on the head. “Aha!” he shouts, or perhaps, “Eureka!” In a flash he understands that the very same force that brought the apple crashing toward the ground also keeps the moon falling toward the Earth and the Earth falling toward the sun: gravity. Or something like that. The apocryphal story is one of the most famous in the history of science and now you can see for yourself what Newton actually said. Squirreled away in the archives of London’s It is the manuscript for what would become a biography of Newton entitled Memoirs of Sir Isaac Newton’s Lifewritten by William Stukeley, an archaeologist and one of Newton’s first biographers, and published in 1752. Newton told the apple story to Stukeley, who relayed it as such: “After dinner, the weather being warm, we went into the garden and drank thea, under the shade of some apple trees…he told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind. It was occasion’d by the fall of an apple, as he sat in contemplative mood. Why should that apple always descend perpendicularly to the ground, thought he to himself…” The Royal Society has made the manuscript available today for the first time in a fully interactive digital form on their website at Seeing Further (HarperPress, £25), an illustrated history of the Royal Society edited...

Isaac Newton: Who He Was, Why Apples Are Falling

Legend has it that Isaac Newton formulated gravitational theory in 1665 or 1666 after watching an apple fall and asking why the apple fell straight down, rather than sideways or even upward. "He showed that the force that makes the apple fall and that holds us on the ground is the same as the force that keeps the moon and planets in their orbits," said Martin Rees, a former president of Britain's Royal Society, the United Kingdom's national academy of science, which was once headed by Newton himself. "His theory of gravity wouldn't have got us global positioning satellites," said Jeremy Gray, a mathematical historian at the Milton Keynes, U.K.-based Open University. "But it was enough to develop space travel." Isaac Newton, Underachiever? Born two to three months prematurely on January 4, 1643, in a hamlet in Lincolnshire, England, Isaac Newton was a tiny baby who, according to his mother, could have fit inside a quart mug. A practical child, he enjoyed constructing models, including a tiny mill that actually ground flour—powered by a mouse running in a wheel. Admitted to the University of Cambridge on 1661, Newton at first failed to shine as a student. In 1665 the school temporarily closed because of a bubonic plague epidemic and Newton returned home to Lincolnshire for two years. It was then that the apple-falling brainstorm occurred, and he described his years on hiatus as "the prime of my age for invention." Despite his apparent affinity for private study, Newton retur...
