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.

Nature is written in mathematical language.

The Bible shows the way to go to heaven, not the way the heavens go.
Galileo Galilei

To understand the Universe, you must understand the language in which it's written, the language of Mathematics.
Galileo Galilei
Image
They know that it is human nature to take up causes whereby a man may oppress his neighbor, no matter how unjustly. ... Hence they have had no trouble in finding men who would preach the damnability and heresy of the new doctrine from the very pulpit.

All truths are easy to understand once they are discovered the point is to discover them.

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.

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?

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

Nature's great book is written in mathematics.
Galileo Galilei

I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments, and demonstrations.

With regard to matters requiring thought: the less people know and understand about them, the more positively they attempt to argue concerning them.

Wine is sunlight, held together by water.

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.

Well, since paradoxes are at hand, let us see how it might be demonstrated that in a finite continuous extension it is not impossible for infinitely many voids to be found.
