More quotes by Johannes Kepler

Image
Yet in this my stars were not Mercury as morning star in the angle of the seventh house, in quartile with Mars, but they were Copernicus, they were Tycho Brahe, without whose books of observations everything which has now been brought by me into the brightest daylight would lie buried in darkness.
Johannes Kepler

Johannes Kepler
Image
If there is anything that can bind the heavenly 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.
Johannes Kepler
Image
If the moon and earth were not retained in their orbits by their animal force or some other equivalent, the earth would mount to the moon by a fifty-fourth part of their distance, and the moon fall towards the earth through the other fifty-three parts, and they would there meet, assuming, however, that the substance of both is of the same density.
Johannes Kepler
Image
O telescope, instrument of much knowledge, more precious than any sceptre!
Johannes Kepler
Image
So long as the mother, Ignorance, lives, it is not safe for Science the offspring, to divulge the hidden causes of things.
Johannes Kepler
Image
The Earth is round, and is inhabited on all sides, is insignificantly small, and is borne through the stars.
Johannes Kepler
Image
Nature uses as little as possible of anything.
Johannes Kepler
Image
[Quantity is the fundamental feature of things,] the 'primarium accidens substantiae,' ...prior to the other categories.
