Johannes Kepler

Johannes Kepler
Johannes Keplerwas a German mathematician, astronomer, and astrologer. A key figure in the 17th century scientific revolution, he is best known for his laws of planetary motion, based on his works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy. These works also provided one of the foundations for Isaac Newton's theory of universal gravitation...

shining mind geometry
Geometry is one and eternal shining in the mind of God
mind creation geometry
Geometry existed before the creation. It is co-eternal with the mind of God...Geometry provided God with a model for the Creation...
sky mind shadow
I measured the skies, now the shadows I measure, Sky-bound was the mind, earth-bound the body rests. [Kepler's epitaph]
eye mind ears
Just as the eye was made to see colours, and the ear to hear sounds, so the human mind was made to understand, not whatever you please, but quantity.
creating humanity mind
Since geometry is co-eternal with the divine mind before the birth of things, God himself served as his own model in creating the world (for what is there in God which is not God?), and he with his own image reached down to humanity.
order mind matter
When things are in order, if the cause of the orderliness cannot be deduced from the motion of the elements or from the composition of matter, it is quite possibly a cause possessing a mind.
book thoughtful mind
Since we astronomers are priests of the highest God in regard to the book of nature, it befits us to be thoughtful, not of the glory of our minds, but rather, above all else, of the glory of God.
cause hidden safe
So long as the mother, Ignorance, lives, it is not safe for Science, the offspring, to divulge the hidden cause of things
borne earth inhabited means
I demonstrate by means of philosophy that the earth is round, and is inhabited on all sides; that it is insignificantly small, and is borne through the stars.
dwell lords shall worlds
But who shall dwell in these worlds if they be inhabited?....Are we or they Lords of the World?....And how are all things made for man?
distance mean squares
The squares of the periodic times are to each other as the cubes of the mean distances.
mean science simple
I am much occupied with the investigation of the physical causes [of motions in the Solar System]. My aim in this is to show that the celestial machine is to be likened not to a divine organism but rather to a clockwork ... insofar as nearly all the manifold movements are carried out by means of a single, quite simple magnetic force. This physical conception is to be presented through calculation and geometry.
science differences path
So, Fabricius, I already have this: that the most true path of the planet [Mars] is an ellipse, which Dürer also calls an oval, or certainly so close to an ellipse that the difference is insensible.
miracle doe crowds
He who will please the crowd and for the sake of the most ephemeral renown will either proclaim those things which nature does not display or even will publish genuine miracles of nature without regard to deeper causes is a spiritually corrupt person... With the best of intentions I publicly speak to the crowd (which is eager for things new) on the subject of what is to come.
