Scientific Wealth Tends To Accumulate According To The Law Of Compound Interest. Every Addition To Knowledge Of The Properties Of Matter Supplies The Physical Scientist With New Instrumental Means For Discovering And Interpreting Phenomena Of Nature, Which In Their Turn Afford Foundations Of Fresh Generalisations, Bringing Gains Of Permanent Value Into The Great Storehouse Of Natural Philosophy.

Suppose That You Could Mark The Molecules In A Glass Of Water; Then Pour The Contents Of The Glass Into The Ocean And Stir The Latter Throughly So As To Distribute The Marked Molecules Uniformly Throughout The Seven Seas; If Then You Took A Glass Of Water Anywhere Out Of The Ocean, You Would Find In It About A Hundred Of Your Marked Molecules.

Fourier's Theorem Is Not Only One Of The Most Beautiful Results Of Modern Analysis, But It May Be Said To Furnish An Indispensable Instrument In The Treatment Of Nearly Every Recondite Question In Modern Physics.

Nothing Can Be More Fatal To Progress Than A Too Confident Reliance On Mathematical Symbols; For The Student Is Only Too Apt To Take The Easier Course, And Consider The Formula Not The Fact As The Physical Reality.

There Is Nothing New To Be Discovered In Physics Now. All That Remains Is More And More Precise Measurement.
