Kepler discovered that planets revolve around the sun in an ellipse or an oval path. When Johannes Kepler was born in the late sixteenth century, scientists believed that planets in the solar system traveled in circular orbits around the Earth. The occasional problem was solved by the addition of miniature circles test — epi-cycles — to planetary paths. But Kepler not only adamantly defended the idea that planets orbit the sun, he also revealed that their paths were not perfect circles. His descriptions of planetary motions became known as Kepler’s laws. Born in December of 1571, young Kepler was a sickly child of poor parents. He was awarded a scholarship to the University of Tübingen, where he studied to become a Lutheran minister. While there, he studied the work of Nicolaus Copernicus, who taught that the planets orbited the sun rather than the Earth, though he had no observational evidence to offer as proof. The Martian problem, which Kepler said he would solve in eight days, took nearly eight years. Astronomers had long struggled to figure out why Mars appeared to walk backwards across the night sky. No model of the solar system — not even Copernicus' — could account for the retrograde motion. Using Brahe's detailed observations, Kepler realized that the planets traveled in "stretched out" circles known as ellipses. The sun didn't sit exactly at the center of their orbit, but instead lay off to the side, at one of the two points known as the focus. Though Kepler is best known for his defining laws regarding planetary motion, he made several other notable contributions to science. He was the first to determine that refraction drives vision in the eye, and that using two eyes enables depth perception. He created eyeglasses for both near and farsightedness, and explained how a telescope worked. He described images and magnification, and understood the properties of reflection. Kepler had a unique perception of Earth, the Sun and how the planets were connected in our Solar System. Truly he was a gifted man.

Kepler was a man who is known for not only being vital to our planets solar system, but also for his backstory and his motivation to love math. Thank you Mrs.Taylor for the blog today!

You haven't put up a new blog today Mrs.Taylor. I don't blame you. You have SEP's so that kind of takes up all of your time. Trust me I know. In 3rd well practically 4th grade I was swamped so badly I couldn't finish everything. I had 3 pages of math homework, A spelling packet to finish and a book report I hadn't even started on because I was swamped the whole week I cried for 2 hours then I worked harder then I think I've ever worked in my entire life. Well so far. I know that one well more than one day in my life that will be really close to just making my brain explode. I can't wait till tomorrow. I love the seasons and how Utah gets EVERYTHING!!! It's also weird that 17% of your class last year didn't let go of their way of thinking! BTW: HI EVERYONE!!!!!!!

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
