Nature's great book is written in mathematics.
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
I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments, and demonstrations.
Galileo Galilei
Image
To excite in us tastes, odors, and sounds I believe that nothing is required in external bodies except shapes, numbers, and slow or rapid movements. ... if ears, tongues, and noses were removed, shapes and numbers and motions would remain, but not odors or tastes or sounds.
Galileo Galilei
Image
Surely it is a great thing to increase the numerous host of fixed stars previously visible to the unaided vision, adding countless more which have never before been seen, exposing these plainly to the eye in numbers ten times exceeding the old and familiar stars.
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.

Image
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
And believe me, if I were again beginning my studies, I should follow the advice of Plato and start with the mathematical sciences, which proceed very cautiously and admit nothing as established until it has been rigorously demonstrated.
Galileo Galilei
Image
But, because my private lectures and domestic pupils are a great hinderance and intteruption of my studies, I wish to live entirely exempt from the former, and in great measure from the latter. ... in short, I should wish to gain my bread from my writings.
Galileo Galilei
Image
Holy Scripture could never lie or err...its decrees are of absolute and inviolable truth.
Galileo Galilei
Image
It has always seemed to me extreme presumptuousness on the part of those who want to make human ability the measure of what nature can and knows how to do, since, when one comes down to it, there is not one effect in nature, no matter how small, that even the most speculative minds can fully understand.
Galileo Galilei
Image
I have never met a man so ignorant that I couldn't learn something from him.
Galileo Galilei
Image
Mathematics is the language with which God has written the universe.
Galileo Galilei
Image
Measure what can be measured, and make measureable what cannot be measured.
Galileo Galilei
Image
Wine is sunlight, held together by water.
Galileo Galilei
Image
I believe that the intention of Holy Writ was to persuade men of the truths necessary to salvation such as neither science nor other means could render credible, but only the voice of the Holy Spirit.
Galileo Galilei
Image
I would beg the wise and learned fathers [of the church] to consider with all diligence the difference which exists between matters of mere opinion and matters of demonstration.
Galileo Galilei
Image
They who depend upon manifest observations will philosophize better than those who persist in opinions repugnant to the senses.
Galileo Galilei
Image
If experiments are performed thousands of times at all seasons and in every place without once producing the effects mentioned by your philosophers, poets, and historians, this will mean nothing and we must believe their words rather than our own eyes?
Galileo Galilei

You cannot teach a person something he does not already know, you can only bring what he does know to his awareness.
