**Measurement**

Because energy is defined as the ability to do work on objects, there is no absolute measure of energy. Only the transition of a system from one state into another can be defined and thus energy is measured in relative terms. The choice of a baseline or zero point is often arbitrary and can be made in whatever way is most convenient for a problem.

“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the *measurement* of future events and they never are, if you have high standards of accuracy.”

—John Dos Passos (1896–1970)
