The book of nature is written in the language of mathematics.

Wine is sunlight, held together by water.
Galileo Galilei

Measure what can be measured, and make measureable what cannot be measured.

My dear Kepler, what would you say of the learned here, who, replete with the pertinacity of the asp, have steadfastly refused to cast a glance through the telescope? What shall we make of this? Shall we laugh, or shall we cry?
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.
Galileo Galilei
Image
I do not know what to say in a case so surprising, so unlooked for and so novel.
Galileo Galilei
Image
Nothing physical which sense-experience sets before our eyes, or which necessary demonstrations prove to us, ought to be called in question (much less condemned) upon the testimony of biblical passages...

To understand the Universe, you must understand the language in which it's written, the language of Mathematics.

With regard to matters requiring thought: the less people know and understand about them, the more positively they attempt to argue concerning them.
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
Facts which at first seem improbable will, even on scant explanation, drop the cloak which has hidden them and stand forth in naked and simple beauty.
Galileo Galilei
Image
The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.
Galileo Galilei
Image
I am inclined to think that the authority of Holy Scripture is intended to convince men of those truths which are necessary for their salvation, which, being far above man's understanding, can not be made credible by any learning, or any other means than revelation by the Holy Spirit.
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
The vain presumption of understanding everything can have no other basis than never having understood anything. For anyone who had ever experienced just once the perfect understanding of one single thing, and had truly tasted how knowledge is accomplished, would recognize that of the infinity of other truths he understands nothing.
Galileo Galilei

Holy Scripture could never lie or err...its decrees are of absolute and inviolable truth.
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
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.
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.

It is very pious to say and prudent to affirm that the holy Bible can never speak untruth -- whenever its true meaning is understood. But I believe nobody will deny that it is often very abstruse, and may say things which are quite different from wha.
