The physical chemists combine both these characteristics in that they apply imprecise methods to impure materials.

Happiness is equal to work minus resistance.

I must consider the organizer as more important than the discoverer.

A catalyst is a substance which alters the velocity of a chemical reaction without appearing in the final products.
