Know Yourself To Improve Yourself.

Every Attempt To Employ Mathematical Methods In The Study Of Chemical Questions Must Be Considered Profoundly Irrational And Contrary To The Spirit Of Chemistry.... If Mathematical Analysis Should Ever Hold A Prominent Place In Chemistry -- An Aberration Which Is Happily Almost Impossible -- It Would Occasion A Rapid And Widespread Degeneration Of That Science.

The Mathematical Thermology Created By Fourier May Tempt Us To Hope That, As He Has Estimated The Temperature Of The Space In Which We Move, Me May In Time Ascertain The Mean Temperature Of The Heavenly Bodies: But I Regard This Order Of Facts As For Ever Excluded From Our Recognition. We Can Never Learn Their Internal Constitution, Nor, In Regard To Some Of Them, How Heat Is Absorbed By Their Atmosphere. We May Therefore Define Astronomy As The Science By Which We Discover The Laws Of The Geometrical And Mechanical Phenomena Presented By The Heavenly Bodies.
