While at Pisa and Padua, Galileo was busy working out the mechanics of his observations. It would be a long time before he actually published his results. One of his major contributions to mechanics was his theory of inertia. He conducted numerous experiments by rolling balls on a variety of inclines. Using various inclines, and various size balls, his observations led him to a new understanding of what is ‘natural’ to objects. First, he stated that motion is as natural as rest for any object. Secondly, he rebutted the medieval thought that all motion could be explained in terms of cause and purpose. “I hold,” Galileo stated, “that there exists nothing in external bodies ... but size, shape, quantity and motion.” Galileo became famous for his astronomical observations in the early 1600’s, and earned a position at the Florentine court. Early in 1609, Galileo learned of the invention of a telescope that was able to magnify objects up to 3 times. After acquiring one, he improved upon it and made the first the first astronomically useful instrument. In his writing, Sidereus Nuncius (The Starry Messenger, written in 1610), he described his observations of the

Newton along with Galileo had a huge impact of Scientific Revolution because he helped shape it in powerful ways. Newton developed a physical law that has become known as Newton’s Law of Universal Gravitation. In scientific jargon, the law states, ‘any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them’ Another major contribution made by Newton was the formulation of the Laws of Motion. Newton created three of them. Newton's’ first law recognized Galileo’s concept, this law is often referred to as the term of inertia. ELABORATE AND

Among these people were Copernicus who believed the sun was at the center of the world and the earth, stars and planets revolved around it. Danish astronomer Brahe helped contribute to this idea by contributing a large mass of data about the universe that he was able to discover. His student Kepler kept his ideas going, as he formulated many laws of planetary motion. He said the orbits around the sun were elliptical, planets don’t move in a uniform speed and the time a planet completes its orbit is related to its distance from the sun. Meanwhile, Florentine Galileo decided to use experiments to find out what happened and not what should happen, and discovered that a uniform force makes a uniform acceleration as well as inertia laws, that an object will be in motion forever unless stopped by another force.

Andreas Vesalius published a book entitled “The Fabric of the Human Body” which was published around the time that printing first came about. His specialism was anatomy, and in the book that he

Before Newton talked about gravitation the main knowledge of scientists was a elementary knowledge of optics, mechanics and astronomy.Copernicus Kepler and Galileo provided the background knowledge of the stars and planets, but Newton used their data to discover the whole gravitational system.10Newton reasoned that the planets and all other physical objects in the universe moved through mutual attraction of gravity.Newton said that every other object in the universe affected every other object through gravity.This explained why the planets move in an orderly fashion. Newton found that “the force of gravity towards the whole planet did arise from and was compounded of the forces of gravity towards all it’s parts, and towards every one part was in the inverse proportion of the squares of the distances from this part.”Newton proves all of this mathematically. This was known to be the single most important contribution to physics that ever has been made.11

Despite maturing in growth, Isaac was almost always absentminded. He thought of problems in his head and ignored any other subject until he solved them. Writing on a journal where he plastered his thoughts, Isaac continued to write theories on mathematics and laws of gravity. It was then that Newton realized what he wanted to do; he wanted to explore territory that other scientists had not dared to observe. In 1666, at the mere age of twenty three, Isaac presented his theory of gravitation. He was able to explain that a particle attracts to every other particle using a force directly proportional to the square of the distance between them. His breakthrough find has not just transformed the idea of gravitation around Earth but universal gravitation as a

Although this theory was created by a fellow scientist, Copernicus, Galileo Galilei first proved the theory. With his telescope that he had created from refining the existing idea, he discovered Jupiter with 4 lights appearing to circle it, orbiting Jupiter. This meant that the earth must not be the only planet with other objects orbiting it. The moons are now named the Galilean moons in his honour. He discovered that Venus had phases, just like the moon, meaning it must be orbiting the sun and not the earth. This supported the theory that the other planets were not circling the earth like the catholic church and scientists of the time were teaching, but all the planets (including the Earth) were in fact all circled around the sun. This discovery caused him to speak out openly against common belief of geocentrism (the earth as the center of the universe) and caused a disruption within the church. He presented many lectures on the topic and exposed his point of view, and the church started calling the catholic man a heretic. In 1616, they warned him against further pursuing and proving the Copernican theory. He obeyed the church for many years, where he was allowed to continue his research, as long as he didn't continue researching, producing material, or spreading the Copernican theory. In 1632, he created a paper called 'dialogue of the 2 world systems', which showed three theoretical

Andreas Vesalius, a Belgian physician, is known as the founder of human anatomy for revolutionizing medicine and biology through his findings of the anatomy of the human body. From 1533 to 1536, Vesalius studied at the University of Paris. There, he learned to dissect animals and obtained many human corpses to dissect too. He devoted most of his time to studying human bones, plentiful in cemeteries throughout Paris. At the time, Vesalius relied on the theories of Galen, a Greek physician, until he realized that the books on anatomy that were written by Galen were based on the dissections of animals, not humans. Vesalius’s book on anatomy, commonly known as the Fabrica, was printed in 1543. This book became widely known, detailing and teaching

In 1543 Nicholas Copernicus, a Polish Canon, published “On the Revolution of the Celestial Orbs”. The popular view is that Copernicus discovered that the earth revolves

By using Kepler's laws of planetary motion from this system, Newton was the first person to show that the motion of objects on Earth and of celestial bodies is ruled by the same set of natural laws (“Isaac Newton –

Suggested a motorized universe with small solid masses in motion and discovered the colour spectrum and developed the three laws of motion. (George.2007)

Have you ever heard of the story of an apple dropping on Isaac Newton’s head. That giving him the Ah moment of the theory of gravitation. Well that the story is not true, however what had happened was that Isaac Newton was walking in his orchard that was at his home. Then he saw an apple had fallen off the tree and he thought “ Why did the apple fall downwards not sideways or upward”. That had sparked the great journey of Isaac Newton.

Sir Isaac Newton a famous philosopher, astronomer, physicist, scientist and mathematician was mostly known for his law of gravitation that states, “that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.” Newton was born on January 4, 1643, in Woolsthorpe, England. At the age of 12, he was enrolled to the King’s School in Grantham, a town in Lincolnshire. However after a while his mother pulled him out of school due to the fact that she wanted to make him a farmer but he did not enjoy farming. Thankfully, he was sent back to King’s school to finish his education. His uncle , a graduate of the University

Isaac Newton discovered how gravity works.He developed the theory of gravity and the laws of motion. Isaac Newton studied gravity for over 20 years and did the same work for 20 years. He learned mathematics he was able to come up with this ideas by the mix of theory and practice. He published his notes to show the world how gravity works.

Many great thinkers contributed to the recent discovery of gravitational waves. Aristotle was the first to consider gravity thinking that objects fell to the earth because it was the natural place of the object to be on the ground. Galileo decided that Aristotle’s idea needed to be tested scientifically and he discovered that objects fall with “a constant acceleration along a parabolic curve.” During the Apollo 15 mission, Galileo’s theory that all objects fall with the same speed was proved when officer David Scott held the famous feather and hammer experiment on the moon. Sir Isaac Newton famously contributed his Law of Gravity which mathematically explained gravity. Although it was mathematically explained, the physical nature of gravity
