I abjure with a sincere heart and unfeigned faith, I curse and detest the said errors and heresies, and generally all and every error and sect contrary to the Holy Catholic Church.
Galileo Galilei
Image
To be humane, we must ever be ready to pronounce that wise, ingenious and modest statement 'I do not know'.
Galileo Galilei
Image
To understand the Universe, you must understand the language in which it's written, the language of Mathematics.
Galileo Galilei
Image
In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.
Galileo Galilei
Image
When the moon is ninety degrees away from the sun it sees but half the earth illuminated (the western half). For the other (the eastern half) is enveloped in night. Hence the moon itself is illuminated less brightly from the earth, and as a result its secondary light appears fainter to us.

Philosophy itself cannot but benefit from our disputes, for if our conceptions prove true, new achievements will be made if false, their refutation will further confirm the original doctrines.
Galileo Galilei
Image
One can understand nature only when one has learned the language and the signs in which it speaks to us but this language is mathematics and these signs are methematical figures.
Galileo Galilei
Image
Mathematics is the language with which God has written the universe.
Galileo Galilei
Image
But some, besides allegiance to their original error, possess I know not what fanciful interest in remaining hostile not so much toward the things in question as toward their discoverer.
Galileo Galilei
Image
In time you may discover everything that can be discovered, and still your progress will only be progress away from humanity. The distance between you and them can one day become so great that your joyous cry over some new gain could be answered by an universal shriek of horror.
Galileo Galilei
Image
All truths are easy to understand once they are discovered the point is to discover them.
Galileo Galilei
Image
They seemed to forget that the increase of known truths stimulates the investigation, establishment and growth of the arts not their dimination or destruction.
Galileo Galilei
Image
Some, merely to contradict what I had said, did not scruple to cast doubt upon things they had seen with their own eyes again and again.

Science proceeds more by what it has learned to ignore than what it takes into account.

Nature is written in mathematical language.
Galileo Galilei
Image
The laws of Nature are written in the language of mathematics...the symbols are triangles, circles and other geometrical figures, without whose help it is impossible to comprehend a single word.
