Geometry Is The Most Complete Science.

Galileo Was No Idiot. Only An Idiot Could Believe That Science Requires Martyrdom - That May Be Necessary In Religion, But In Time A Scientific Result Will Establish Itself.

Geometry, Like Arithmetic, Requires For Its Logical Development Only A Small Number Of Simple, Fundamental Principles. These Fundamental Principles Are Called The Axioms Of Geometry.

Physics Is Much Too Hard For Physicists.

As Long As A Branch Of Science Offers An Abundance Of Problems, So Long It Is Alive; A Lack Of Problems Foreshadows Extinction Or The Cessation Of Independent Development.

No Other Question Has Ever Moved So Profoundly The Spirit Of Man; No Other Idea Has So Fruitfully Stimulated His Intellect; Yet No Other Concept Stands In Greater Need Of Clarification Than That Of The Infinite.
