Those [scientists] Who Dislike Entertaining Contradictory Thoughts

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

Scientific Work Will Never Stop, And It Would Be Terrible If It Did. If There Were No More Problems, You Would Put Your Hands In Your Pockets And Your Head On A Pillow And Would Work No More. In Science Rest Is Stagnation, Rest Is Death.

Anybody Who Has Been Seriously Engaged In Scientific Work Of Any Kind Realizes That Over The Entrance To The Gates Of The Temple Of Science Are Written The Words: 'ye Must Have Faith.'

The Worth Of A New Idea Is Invariably Determined, Not By The Degree Of Its Intuitiveness-which Incidentally, Is To A Major Extent A Matter Of Experience And Habit-but By The Scope And Accuracy Of The Individual Laws To The Discovery Of Which It Eventually Leads.

Experiment Is The Only Means Of Knowledge At Our Disposal. Everything Else Is Poetry, Imagination.
