lying science heaven
I used to measure the Heavens, now I measure the shadows of Earth. The mind belonged to Heaven, the body's shadow lies here.
vectors equal radius
The radius vector describes equal areas in equal times.
philosophical mathematics pleasure
I also ask you my friends not to condemn me entirely to the mill of mathematical calculations, and allow me time for philosophical speculations, my only pleasures.
moon sea water
If the earth should cease to attract its waters to itself all the waters of the sea would be raised and would flow to the body of the moon.
way orbs kind
We find, therefore, under this orderly arrangement, a wonderful symmetry in the universe, and a definite relation of harmony in the motion and magnitude of the orbs, of a kind that is not possible to obtain in any other way.
kind creator
[God] is the kind Creator who brought forth nature out of nothing.
moon water movement
The moon... is a mass, akin to the mass of the earth, attracts the waters by a magnetic force, not because they are liquid, but because they possess earthy substance, and so share in the movements of a heavy body.
astrology nonsense hard
I am a Lutheran astrologer, I throw away the nonsense and keep the hard kernel.
stars sides earth
The Earth is round, and is inhabited on all sides, is insignificantly small, and is borne through the stars.
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.
believe animal design
The cause of the six-sided shape of a snowflake is none other than that of the ordered shapes of plants and of numerical constants; and since in them nothing occurs without supreme reason-not, to be sure, such as discursive reasoning discovers, but such as existed from the first in the Creators's design and is preserved from that origin to this day in the wonderful nature of animal faculties, I do not believe that even in a snowflake this ordered pattern exists at random.
science mystery reason
Eyesight should learn from reason.
knowledge telescopes instruments
O telescope, instrument of knowledge, more precious than any sceptre.
morning stars lying
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.
