in fact not a few days, but a few hours ago; and since the same Paul told me about his return to Germany I judged that I would truly be ungrateful if I did not thank you with this letter for the gift I have received. Therefore I am doing so, and I do so again, as much as ...
Did Leonardo da Vinci's extensive unpublished research on optics and astronomy influence Kepler's Optics, di- rectly or indirectly? There are many areas in which Leonar- do's work certainly presaged that of Kepler.Kepler's book, for example, contains extensive discus- sion of the camera ...
Kepler had studied astronomy long before he met Tycho; he favored the Copernican world-view that said the planets orbited the Sun. Kepler also corresponded with Galileo about his observations and conclusions. Eventually, based on his work, Kepler wrote several works about astronomy, includingAstronom...
"This discovery is the first clear detection of significant changes in the intervals from one planetary transit to the next, what we call transit timing variations," said Matthew Holman, a Kepler mission scientist from the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. "This is e...
Kepler’s Third Law is used over and over again in astronomy. Astronomers use it to measure the mass of the central object around which an object orbits. In this assignment we’ll put it to the test! We will measure the planets’ orbital periods and radii, and see if Kepler’s Th...
There'sa new advance in the possibility for direct observation of exoplanets, reportedWebster Cash, Director of the Center for Astrophysics and Space Astronomy hereat the University of Colorado. Cashhas been working on an idea tagged as the New Worlds Observer, receiving earlyfinancial support and ...
Q: What skills are needed, and how do you do it? A:Versatility. Lab managers are the key risk managers for their lab. They are the gatekeepers to resources, prioritizing tasks, purchasing equipment, and delegating responsibilities. For this reason, they need to know a little ab...

Kepler’s name is associated principally with the laws of planetary motion. The first two laws were published in his -New Astronomy, the third in The Harmony of the World. Their discovery excited him almost to the point of ecstasy: “A very few days after the pure Sun of that most wonde...
