Thus, The Photons Which Constitute A Ray

Truth Never Triumphs-its Opponents Just Die Out.

It Is Never Possible To Predict A Physical Occurrence With Unlimited Precision.

When I Began My Physical Studies [in Munich In 1874] And Sought Advice From My Venerable Teacher Philipp Von Jolly...he Portrayed To Me Physics As A Highly Developed, Almost Fully Matured Science...possibly In One Or Another Nook There Would Perhaps Be A Dust Particle Or A Small Bubble To Be Examined And Classified, But The System As A Whole Stood There Fairly Secured, And Theoretical Physics Approached Visibly That Degree Of Perfection Which, For Example, Geometry Has Had Already For Centuries.

No Burden Is So Heavy For A Man To Bear As A Succession Of Happy Days.

Physical Changes Take Place Continuously, While Chemical Changes Take Place Discontinuously. Physics Deals Chiefly With Continuous Varying Quantities, While Chemistry Deals Chiefly With Whole Numbers.
