The metaphor between Kepler and Brahe....?

Question

Please would you explain to me of how the story of how Johannes Kepler and Tycho Brahe coming together is a great metaphor for the importance of the use of the two tools of modern science working together.

Answer 1

Kepler's great contribution to astronomy was the discovery of the basic principles of planetary motion: 1) their orbits are ellipses with the Sun at one focus, 2) they sweep out equal areas in equal times, and 3) the ratio of orbital period squared to average distance cubed is constant.

He was able to do this because he was a brilliant mathematician, because he persisted in working on the problem for years, and because Tycho Brahe, somewhat grudgingly, had given him his observational data on Mars.

Tycho 's contribution was that he built an observatory that enabled him to measure the positions of stars and planets to much greater precision than had ever been done before. It was this data that enabled Kepler to accurately determine the orbit of Mars.

In scientific terms, Kepler was a theoretician, while Tycho was an experimentalist. Their collaboration is probably not the best example of how these two types of scientists work together. For one thing, Tycho was somewhat fearful of Kepler getting all the glory by making some great discovery based on his data, and was reluctant to share too much. Furthermore, Kepler's eventual discovery (which came several years after Tycho died) was in contradiction to Tycho's theory of the Solar system: that the planets orbited the Sun, but the Earth stood still and the Sun and its planets orbited Earth. Also, the collaboration was mostly one-way - Kepler used Tycho's data, but his work did not give direction to Tycho's. In modern science, experiment and observation are most often guided by theory, attempting to find evidence for or against.

"metaphor" as a determine of speech that makes use of one element to point yet another and makes a assessment between the two. as an occasion, Shakespeare's line, "each and all the international's a point," is a metaphor comparing the great international to a theater point A simile, that's called an open assessment, is a sort of metaphor that compares 2 particularly some issues to create a sparkling meaning. yet a simile continuously makes use of "like" or "as" interior the word and is extra convey than a metaphor. as an occasion, Shakespeare's line must be rewritten as a simile to study: "the international is almost a point." yet another simile could be:
