(Image credit: Johannes Kepler/PD-US) How did astronomers discover that there is such a thing as the perihelion and aphelion? Did they realize the sun was bigger or smaller during certain periods of the year? The answer is no. Edward Bloomer, an astronomer at the Royal Observatory in ...

meaning that they did not make copies of it, they just wrote a new one. To hide what they were writing, they came up with a language where words and spells had more than one meaning. The Torah read like a normal book would tell the story of Jesus Bar Abbas, the leader of the Mili...
A simple introduction to science and the scientific method. Why does science matter and how did it evolve through history?
Did the planets orbit differently before Kepler discovered that p2=a3? Clearly, mathematical laws are something that human beings have discovered, not invented. The only thing that might have been different (had human history taken a different course) is the notation—the way in which we choose...
German mathematician and astronomer Johannes Kepler (1571-1630) also helped to refine the heliocentric model with his introduction ofelliptical orbits. Prior to this, the heliocentric model still made use of circular orbits, which did not explain why planets orbited the Sun at different speeds at ...

The stable orbits of satellites would be possible without considering the laws of both Isaac Newton and Johannes Kepler. You can read about the life of Keplar and his laws of planetary motion courtesy of NASA. Learn about the different types of orbits in more detail with these resources from ...
ve known about solar system motions precisely since the days of Johannes Kepler, it always seems a bit like magic to many people when we count down by the second and an eclipse starts. And then, even with thick clouds visible way down to the south, we had a long, vertical corridor o...
What year was Johannes Kepler born? What date did Henry VII become king? What year did Al Capone die? What date was the revolution against Porfirio Diaz? What year did Juan Peron die? What year did Thomas Edison get married? What year did Garrett Morgan invent the gas mask? How old was...
