We Must Say That There

Philosophy [nature] Is Written In That Great Book Which Ever Is Before Our Eyes -- I Mean The Universe -- But We Cannot Understand It If We Do Not First Learn The Language And Grasp The Symbols In Which It Is Written. The Book Is Written In Mathematical Language, And The Symbols Are Triangles, Circles And Other Geometrical Figures, Without Whose Help It Is Impossible To Comprehend A Single Word Of It; Without Which One Wanders In Vain Through A Dark Labyrinth.

What Has Philosophy Got To Do With Measuring Anything? It's The Mathematicians You Have To Trust, And They Measure The Skies Like We Measure A Field.

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.

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. ... [i]t Is Not In The Power Of Professors Of The Demonstrative Sciences To Alter Their Opinions At Will, So As To Be Now Of One Way Of Thinking And Now Of Another. ... [d]emonstrated Conclusions About Things In Nature Of The Heavens, Do Not Admit Of Being Altered With The Same Ease As Opinions To What Is Permissible Or Not, Under A Contract, Mortgage, Or Bill Of Exchange.

The Book Of Nature Is Written In The Language Of Mathematics.
