Would Johannes Kepler have been as successful as he was if Brahe had not come before him?
Johannes Kepler
What conclusion did Kepler eventually come to that revolutionized the heliocentric model of the solar system?
kepler determined the planetary orbits were elliptical
How did Johannes Kepler come up with his three laws of motion?
Kepler's laws are about the planets' orbits. The first law says that the orbit of any planet around the Sun is an ellipse with the Sun at one of the focii. The second law states that the line joining the Sun to a planet covers equal area in equal intervals of time. The third law states the square of the time period of the planet is proportional to the cube of the semi-major axis of its elliptical orbit. Kepler's law explained planetary motion, but nothing other than motion, and really no one could properly explain why Kepler's law worked. So therefore we move on to Newton's first law.
What did Thyco Brahe study?
Mostly, his eyes and pen. He also used azimuth circles that circumscribed his observatory at Uraniborg to assist him in accurately plotting the movements of the stars, planets and other celestial objects. Brahe also built a sextant many times larger than any that had been built before, increasing it's accuracy notably. No previous observer had ever recorded so many detailed positions of objects in the heavens.
What was Johannes Kepler's nickname?
1. planets travel in elliptical orbits around an off-centre sun. 2. the speed of a planet's orbit depends on its distance from the sun. when a planet's close to the sun it, orbits faster. when it's further away from the sun, it travels slower 3. the farther a planet or dwarf planet is from the sun, the longer its orbit *note: did this because there weren't any fricken answers on the web that was specific, easy and in point form answer. Have fun!!!!! (you probably won't) lol :P
Who was Johannes Kepler mentor?
He did his best work with Tycho Brahe who was a Danish nobleman who employed Kepler as a mathematician, a fairly junior appointment. Tycho tended to keep his measurements secret, to retain control, but after his death Kepler was able to to get full access and then produced his famous three laws of planetary motion.
What is use of Johannes Kepler's invention telescope?
A telescope is used to magnify things that are far away.That said, I'm not sure who told you that Johannes Kepler invented the telescope. He didn't invent the telescope itself, but he did come up with a new design. Kepler's design uses a convex lens at the eyepiece rather than a concave one. This has several advantages, but a couple of disadvantages, such as the image appearing upside down. This makes it largely useless for terrestrial work, but it's suitable for astronomy, which is what Kepler was interested in anyway.
How did Tycho Brahe contribute Kepler's laws?
Tycho, for the most part, just gathered a vast amount of data of the planets and their movements. He didn't really do much analyzing of the data to come up with laws or theories. That was done after his death by his assistant, Johannes Kepler, who took that very data and discovered alot about how the planets move and orbit the sun. But Tycho's contribution was significant because he devised ways of measuring the positions of planets and other objects that were more accurate than ever before. These allowed Kepler to do better calcuations than before and discover the small differences between the old model of planetary orbits and the elliptical orbits that Kepler discovered and passed on to later scientists.
How did humanism effect Johannes Kepler's work?
Humanists like to think of the universe as a cohesive whole, and believe that everything has a reason. This belief caused Kepler to try to come up with holistic interpretations of astronomical truths, so, even though he gathered a lot of empirical evidence, much of his work that we ignore in modern times was speculation on the structure of the universe. For example, he was pretty excited to come up with a theory based on geometric structures and how they fit in with the orbit of the planets. Look up Kepler's Polygons. It makes a nice picture, but it later turned out to be wrong. Kepler also refused to use the Copernican system (though he was okay with the Tychonian system, apparently?) because having the sun in the center of the universe messed up his perception of the natural order of things. All in all, Kepler refused to publish anything unless it fit in with his humanistic perceptions. He did end up finishing Tycho Brahe's planetary charts, though.
When were elliptical orbits discovered?
1602 AD by Johannes Kepler. Kepler gave us the orbital law of the Earth orbiting the Sun in an ellipse. The Law states , that Earth sweeps equal arcs of the orbit in equal times. The Sun is at one of the foci of the ellipse, not the centre. The other foci might be termed as a 'blind' focus; nothing there. It has subsequently been found that the planets, Earth included, do not orbit in a closed ellipse, but in an Ellipsoid. An ellipsoid is the track were the planet 'overshoots' its starting point on its previous orbit. Al the planets and the natural satellites (moons) do this in there respective ellipsoidal orbits.
Who was the first astronomer to discover the fact that the planets orbit the sun?
Copernicus was the first to come up with a serious model with the sun at the centre, and Kepler's work on his laws of planetary motion nailed the orbital shape down as an ellipse. After Newton's time it was discovered that the Sun is much more massive than the planets and it therefore made theoretical sense to have it fixed at the centre, and now that is accepted as the truth by everyone.
Who recorded position of stars?
This activity goes back to prehistoric times. The whole purpose of sun circles and stone hedge was to measure and record the yearly position of the sun and stars. Thepreeminent enthusiast in this field however was Tycho Brahe. After his death people fought over the right to inherit his recordings. It was his data on the planet Mars that lead Johann Kepler to come up with the laws of planetary motion.
