Tycho Brahe, Johannes Kepler and Planetary Motion
About | Information | History | Online | Facts | Discovery
In astronomy, Kepler's laws of planetary motion are three scientific laws describing the motion of planets around the Sun. 1. The orbit of a planet is an ellipse with the Sun at one of the two foci. 2. A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. 3. The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit. Most planetary orbits are almost circles, and careful observation and calculation is required in order to establish that they are actually ellipses. Calculations of the orbit of the planet Mars first indicated to Johannes Kepler its elliptical shape, and he inferred that other heavenly bodies, including those farther away from the Sun, also have elliptical orbits. Kepler's work improved the heliocentric theory of Nicolaus Copernicus, explaining how the planets' speeds varied, and using elliptical orbits rather than circular orbits with epicycles. Isaac Newton showed in 1687 that relationships like Kepler's would apply in the solar system to a good approximation, as consequences of his own laws of motion and law of universal gravitation. Kepler's laws are part of the foundation of modern astronomy and physics. Tycho Brahe (14 December 1546 – 24 October 1601), born Tycho Ottesen Brahe, was a Danish nobleman known for his accurate and comprehensive astronomical and planetary observations. He was born in Scania, then part of Denmark, now part of modern-day Sweden. Tycho was well known in his lifetime as an astronomer, astrologer and alchemist, and has been described more recently as "the first competent mind in modern astronomy to feel ardently the passion for exact empirical facts. Johannes Kepler (December 27, 1571 – November 15, 1630) was a German mathematician, astronomer, and astrologer. A key figure in the 17th century scientific revolution, he is best known for his laws of planetary motion, based on his works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy. These works also provided one of the foundations for Isaac Newton's theory of universal gravitation.

great video! brahe! kepler! science!!

He taught us , the most important thing is to find out the truth out of so many data!!!

Pari Spolter’s latest book Dance of the Moon explains the complex motion of the Moon. In this book, you will not find a long series of advanced mathematical equations.) and the following:
Equal areas are swept in equal intervals of time only near perihelion and aphelion, and that is all that Kepler himself has claimed.

Dr. Pari Spolter, the author of Gravitational Force of the Sun, delivers a lecture titled "Kepler's Second Law and Conservation of Angular Momentum" at CSUN.Equating the gravitational force with the quantity or density of inert matter is incorrect. The correct interpretation of Kepler’s third law is: Gravitational force is equal to acceleration times the area: F = a . A. The weight of a body is equal to its mass times the acceleration: W = m . a. Weight is not Force. Please see my book GRAVITATIONAL FORCE OF THE SUN, my articles “New Concepts in Gravitation” in PHYSICS ESSAYS, Volume18, (2005), pages 37–49, “Problems with the Gravitational Constant” in INFINITE ENERGY, Volume 10, No. 59, (2005), page 39, and http://parispolter.com/ The Works of Dr. Pari Spolter

Before Einstein, science was based on observational and experimental data. You are hereby invited to rethink the work of Einstein, Newton, and Kepler.Regards,

Kepler kill Tycho Brahe in a party wih poisin

amazing!

a total lie!!! crap!! don't get indoctrinated with this crap.
-
the earth is land not globe. H776. www.blueletterbible.org plug in the word earth and use the blue tool bar on the left to scroll down to H776 for definition. the earth is a level plane and is dirt. not sea not sky. we don't budge. we are geocentric.

Brahe and Ptolemy models are most definitely the closet to what exists. I think the two combined is the answer.

=== Tycho Brahe was right. Watch the movie -"The Principle

Thank's by the video!
