# Scientific Revolution

### Jalen MI 3rd Period

## What was the change?

It was a change in the way people thought. New view of nature emerged, change the Greek view that had dominated science for almost 2,00 years.

## Who were the people associated with the change?

## Sir Isaac Newton Sir Isaac Newton created the three laws of motion. 1 Every body continues in its state of rest or of motion in a straight line unless it is compelled to change that state by force impressed on it. 2 The change of motion is proportional to the motive force impressed and is made in the direction of the straight line in which that force is impressed. 3 To every action there is always opposed an equal reaction: or, the mutual actions of two bodies upon each other are always equal. His monumental Philosophiae Naturalis Principal Mathematica solved the major problem posed by the scientific revolution in mechanics and in cosmology. | ## Galileo Galileo Galilei, who early in the 17th century used the telescope, a recent invention of Dutch lens grinders. In 1610 Galileo announced observations that contradicted many traditional cosmological assumptions. He found out that the moon is not smooth it is jagged and mountains. He was able to derive the law of free fall (the distance, s, varies as the square of the time, t2). Combining this result with his rudimentary form of the principle of inertia | ## Johannes Kepler Johannes Kepler placed the Copernican hypothesis on firm astronomical footing. In 1609 Kepler announced two new planetary laws derived from Tycho’s data: (1) the planets travel around the Sun in elliptical orbits, one focus of the ellipse being occupied by the Sun; and (2) a planet moves in its orbit in such a manner that a line drawn from the planet to the Sun always sweeps out equal areas in equal times. In 1618 Kepler stated his third law, which was one of many laws concerned with the harmonies of the planetary motions: (3) the square of the period in which a planet orbits the Sun is proportional to the cube of its mean distance from the Sun. |

## Galileo

Galileo Galilei, who early in the 17th century used the telescope, a recent invention of Dutch lens grinders. In 1610 Galileo announced observations that contradicted many traditional cosmological assumptions. He found out that the moon is not smooth it is jagged and mountains. He was able to derive the law of free fall (the distance,

*s*, varies as the square of the time,*t*2). Combining this result with his rudimentary form of the principle of inertia## Johannes Kepler

Johannes Kepler placed the Copernican hypothesis on firm astronomical footing. In 1609 Kepler announced two new planetary laws derived from Tycho’s data: (1) the planets travel around the Sun in elliptical orbits, one focus of the ellipse being occupied by the Sun; and (2) a planet moves in its orbit in such a manner that a line drawn from the planet to the Sun always sweeps out equal areas in equal times. In 1618 Kepler stated his third law, which was one of many laws concerned with the harmonies of the planetary motions: (3) the square of the period in which a planet orbits the Sun is proportional to the cube of its mean distance from the Sun.

## How did the change impact society at the time?

Newton laws provided a physical basis for Kepler’s laws, unified celestial and terrestrial physics under one set of laws, and established the problems and methods that dominated much of astronomy and physics for well over a century. Newton could deduce Kepler’s laws of planetary motion. Galileo’s law of free fall is also consistent with Newton’s laws.

## How is that change evidenced in today's modern society?

In today modern society we still use the laws and the inventions that was created back then. Newton three laws are still around and still being used in today's schools. We still use the telescope to look at the moon and other planets to understand space.
