Mathematics Is Written For Mathematicians.

Perhaps There Will Be Prattlers Who, Although Completely Ignorant Of Mathematics, Nevertheless Take It Upon Themselves To Pass Judgment On Mathematical Questions, And On Account Of Some Passage In Scripture, Badly Distorted To Their Purpose, Will Dare To Censure And Assail What I Have Presented Here.

If There Should Chance To Be Any Mathematicians Who, Ignorant In Mathematics Yet Pretending To Skill In That Science, Should Dare, Upon The Authority Of Some Passage Of Scripture Wrested To Their Purpose, To Condemn And Censure My Hypothesis, I Value Them Not, And Scorn Their Inconsiderate Judgement. De Revolutionibus Coelestibus

The Two Revolutions, I Mean The Annual Revolutions Of The Declination And Of The Centre Of The Earth, Are Not Completely Equal; That Is The Return Of The Declination To Its Original Value Is Slightly Ahead Of The Period Of The Centre. Hence It Necessarily Follows That The Equinoxes And Solstices Seem To Anticipate Their Timing, Not Because The Sphere Of The Fixed Stars Moves To The East, But Rather The Equatorial Circle Moves To The West, Being At An Angle To The Plane Of The Ecliptic In Proportion To The Declination Of The Axis Of The Terrestrial Globe.

I Can Easily Conceive, Most Holy Father, That As Soon As Some People Learn That In This Book Which I Have Written Concerning The Revolutions Of The Heavenly Bodies, I Ascribe Certain Motions To The Earth, They Will Cry Out At Once That I And My Theory Should Be Rejected.

Nations Are Not Ruined By One Act Of Violence, But Gradually And In An Almost Imperceptible Manner By The Depreciation Of Their Circulating Currency, Through Its Excessive Quantity.
