Inbetween Copernicus and Sir Issac Newton, Kelper contributed to the understanding of classical mechanics we know today. The German astronomer established the laws of planetary motion, track star and planets and the term Kelper conjecture named after him. His celestial physics-based on Aristotle’s Metaphysics went thought a lot of breakthroughs in the 17th century.
- “I much prefer the sharpest criticism of a single intelligent man to the thoughtless approval of the masses.”
- “We ought not to ask why the human mind troubles to fathom the secrets of the universe. The diversity of the phenomena of nature is so great, and the treasures hidden in the skies so rich, precisely in order that the human mind shall never be lacking in fresh nourishment.”
- “I used to measure the skies, now I measure the shadows of Earth. Although my mind was sky-bound, the shadow of my body lies here.
- “Geometry has two great treasures; one is the Theorem of Pythagoras; the other, the division of a line into extreme and mean ratio. The first we may compare to a measure of gold; the second we may name a precious jewel.”
- “When ships to sail the void between the stars have been built, there will step forth men to sail these ships.”
- “The soul of the newly born baby is marked for life by the pattern of the stars at the moment it comes into the world, unconsciously remembers it, and remains sensitive to the return of configurations of a similar kind.”
- “Discover the force of the skies O Men: once recognised it can be put to use.”
- “Nature uses as little as possible of anything.”
- “The treasures hidden in the heavens are so rich that the human mind shall never be lacking in fresh nourishment.”
- “After the birth of printing books became widespread. Hence everyone throughout Europe devoted himself to the study of literature… Every year, especially since 1563, the number of writings published in every field is greater than all those produced in the past thousand years. The Paracelsians have created medicine anew and the Copernicans have created astronomy anew. I really believe that at last the world is alive, indeed seething, and that the stimuli of these remarkable conjunctions did not act in vain.”
- “I too play with symbols… but I play in such a way that I do not forget that I am playing. For nothing is proved by symbols… unless by sure reasons it can be demonstrated that they are not merely symbolic but are descriptions of the ways in which the two things are connected and of the causes of this connection.”
- “The Earth is round, and is inhabited on all sides, is insignificantly small, and is borne through the stars.”
- “Sky-bound was the mind, Earth-bound the body rests”
- However, before we come to [special] creation, which puts an end to all discussion: I think we should try everything else.”
- “If there is anything that can bind the mind of man to this dreary exile of our earthly home and can reconcile us with our fate so that one can enjoy living,—then it is verily the enjoyment of the mathematical sciences and astronomy.”
- “I have consummated the work to which I pledged myself, using all the abilities that You (God) gave me; I have shown the glory of Your works to men, but if I have pursued my own glory among men while engaged in a work intended for Your glory, be merciful, be compassionate, and forgive.”
- “And I cherish more than anything else the Analogies, my most trustworthy masters. They know all the secrets of Nature, and they ought to be least neglected in Geometry.”
- ‘We do not ask for what useful purpose the birds do sing, for song is their pleasure since they were created for singing. Similarly, we ought not to ask why the human mind troubles to fathom the secrets of the heavens… The diversity of the phenomena of Nature is so great and the treasures hidden in the heavens so rich, precisely in order that the human mind shall never be lacking for fresh nourishment.”
- “If my false figures came near to the facts, this happened merely by chance….These comments are not worth printing. Yet it gives me pleasure to remember how many detours I had to make, along how many walls I had to grope in the darkness of my ignorance until I found the door which lets in the light of truth….In such manner did I dream of the truth.”
- “Ships and sails proper for the heavely air should be fashioned.”
These three simple facts show what we know about space so far > The orbit of every planet is an ellipse with the sun at a focus. A line joining a planet and the sun sweeps out equal areas during equal intervals of time. The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. That is the understanding to our observable universe at the moment.
