Galileo Galilei was an Italian astronomer who disagreed with the Roman Catholic theory of geocentrism. He was not a heretic because he was a Christian and had similar beliefs to the Roman Catholics, but he did not agree with the Church’s theory of the position and movement of Earth in the Solar System. Document A is an excerpt of a letter to Duchess Christina of Tuscany written by Galilei, counter-arguing the heresy claims. In the letter, Galileo wrote, “Can an opinion be heretical and yet have no concern with the salvation of souls?” Although he did not believe in the astronomical theory of the Church, he believed that his scientific thoughts should not interfere with his religious beliefs.
Famous Astronomers Project Antony Hewish was born the youngest of three sons May 11, 1924 in Fowey, United Kingdom. He grew up in Newquay, on the Atlantic coast and while living there, Hewish developed the love for boats and the sea. Hewish attended King’s College and University of Cambridge in 1942. He was active in war at the Royal Aircraft Establishment, Farnborough and the Telecommunications Research Establishment. Antony’s decision to begin research in radio astronomy was heavily influenced by not just his wartime background that consisted of electronics and antennas, but also by one of his teachers, Jack Ratcliffe.
Yesterday, Oct. 4, 1957, the Sputnik 1 was launched into orbit by the Soviet Union. Now, how did we get to this point? According to nasa.gov, in 1AD, people in ancient china people would fill bamboo with a crude form of gunpowder. It was then tossed into fires at festivals, and went off with a bang.
Johannes Kepler was born in Weil der Stadt, Württemberg, on December 27, 1571. [NASA] Heinrich Kepler, Johannes’ father, was a mercenary(a soldier working only for money) as well as a alcoholic. He left the family when Johannes was five. However, as a child, Kepler showed intelligence and was sent to the prestigious University of Tübingen, where he learned about astronomy, and he became particularly interested in the teachings of Nicolaus Copernicus, a Renaissance-era mathematician and astronomer. After graduate school, instead of becoming a Lutheran priest like expected, Kepler went into the field of astronomy.
As the attorney of Galileo 's, inventer of telescope and the person who proved the copernican theory, I would like to negotiate with you to free my client from the death penalty. Our science hasn 't been updated for the past hundreds of years and people everywhere have been taught false information until Galileo came along. I ask you the pope, leader of our town and country if you still care about your people, to free my client so he can serve his true potential of being a scientist. He can show us new ways of learning and provide us with correct information about our world to teach our people. Galileo will change history itself, his discoveries will make a dent in astronomy 100 years from now.
Another huge accomplishment Kepler had was discovering the laws of planetary motion. The first law was that all planets traveled in “stretched out circles” or ellipses. For the second law, Kepler determined that an invisible line that connected the sun
To start with, we should make sense of what these words mean. Gravity: the power that makes something tumble to the ground (at 9.8 m/s²) Newton 's Laws of Motion: three laws that state mechanics portraying the movement of a body. The main law is the law of latency: a body stays very still unless followed up on by an outer power. The second law expresses that a body in movement stays in movement unless followed up on by an outside power. Newton 's third and last law is about how for each activity, there is an equivalent and inverse response.
The circle of a planet is oval shaped where one center of the oval is the sun or Planets move around the Sun in ovals, with the Sun at one focus. A center is one of the two inward focuses that decide the shape of a circle. The separation from one center to any point on the orbit and after that back to the second center is always same. An oval is characterized by two foci and all focuses for which the total of the separations are the same. The closer together that these focuses are, the all the more nearly that the oval takes after the state of a circle.
His famous equation of all the time is F=MA. How he got this equation? He got it from the falling apple fell his head. This lead Newton explore why the apple fell in a straight line but not the other side of direction. Newton first law (It also can be called as law of inertia.)
Isaac’s discovery was gravity, he has experimented apples falling of trees and when they fall off they don 't go back up they fall straight to the ground so he got his theory that gravity did that and that
It was brought on by the sighting of Halley’s Comet and the ensuing mad rush to understand the path in which it travelled and why. The deliberating would turn to debate between Newton and his old nemesis, Hooke. Eventually, Newton would publish “On the Motion of Bodies in Orbit”, his explanation of planetary motion. For this treatise, he coined the term mass to represent how much matter one was referencing, and force to quantify motion. He also used centripetal force in these
Minus the really confusing formula Einstein came up with to explain his theory, the equation is easy enough to understand. It basically states that gravity is more of a distortion of space and time. The energy of an object affects the space around it according to Einstein which makes sense when you know that Isaac Newton has shown us that the gravity of an object depends on its mass, the more the mass, the more energy of said object.
This theory of gravitation may well be his most famous contribution to science. In David Berlinksi’s book Newton’s Gift, he states that, “It is the law of universal gravitation that Newton saw as the frame of the universe, and what the law says is quite simple” (Berlinski 134). This law specifies that objects with mass attract each other with a force that varies directly as the product of their masses and inversely as the square of the distance between the objects. Before Newton, Aristotle had some similar findings. Newton expanded and improved on Aristotle's explanation by figuring out a mathematical expression for the gravitational force between two objects, and by identifying the force which causes apples to fall like the same force that keeps planets in their orbits.
Mickey Ngobeni Research Question: Is the movie ‘Gravity’, according to Newton’s laws and physics in general, accurate? Introduction: ‘Gravity’ is a sci-fi, techno-thriller movie that has its plot’s setting based in space. Astronauts (main characters: Sandra Bullock as ‘Dr. Ryan Stone’ and George Clooney as ‘Matt Kolwaski’) are sent into space, yet encounter a series of events, most of which is susceptible to occur in outer space (Foogray, 2015). Questions have risen as to how accurate the movie is according to physics and Newton’s law, and many have been answered.
Isaac Newton’s first law states that the real effect of a force is always to change the speed of a body, rather than just set it moving, as was previously thought. It also meant that whenever a body was not acted on by any force, it will keep on moving in a straight line at the same speed. What happens to a body when a force does act on it is given by Newton’s second law which states that the body will accelerate, or change its speed, at a rate that is proportional to the force. In addition to his laws of motion, Newton discovered a law to describe the force of gravity, which states that every body attracts every other body with a force that is proportional to the mass of each body.
