Nicolaus Copernicus
Claimed that there was a force making the earth revolve around the sun.
a Renaissance mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at its center. -
Apr 16, 1500
Galileo Galilei
Notion that a force is necessary to keep an object moving -
Galileo Galilei
He induces the period relationship of a pendulum from observation. -
Galileo Galilei
Invented the telescope, discovered that moons orbit around the planets.
Albert Einstein - Theory that says gravity is not a force, but a consequence of a curvature of a space-time. -
Johannas Kepler
Created the Kepler’s law
1. The orbit of every planet is an ellipse with the sun at a focus
2. A line joining the planet and the sun sweeps out equal areas during equal intervals of time
3. The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of it’s orbit. -
Isaac Newton
Issac Newton discovered the Law of Inertia/motion. The Law of Inertia is Newton's first law of motion. Newton's first law of motion is often states as "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force." This means that there is a natural behavior to objects to make it not move. -
Discovery of Gravity
Newton discovered that there is a specific force ( which we call gravity), that is required to change the speed or direction of something that is moving. -
Henry Cavendish
Henry Cavendish measures the force of gravity betwen two masses, leading to the first accurate value for the gravitational constant. -
Albert Einstien
Completes his theory of the special relativity and states the law of mass energy conservation: E=mc2 -
Karl Schwarzschild
Karl Schwarzschild publishes the Schwarzschild metric about a month after Einstein published his general theory of relativity. This was the first solution to the Einstein field equations other than the trivial flat space solution. -
Stephen Hawking
Quantum theory of gravity hawking radiation -
Nicolaus Copernicus
Claimed that there was a force making the earth revolve around the sun. -
Albert Einstein
Albert Einstein introduces the principle of equivalence of gravitation and inertia and uses it to predict the gravitational redshift.
