Dear Hearts:

'Physics' is defined by the Penguin Publishers Dictionary of Science as:
"The study of matter and energy and their interactions."


Webster's New 20th Century Dictionary of 2,129 pages and nearly a quarter of a million words, defines 'Physics', as:

1. Originally natural science or natural philosophy.
2. The science dealing with the properties, changes, interaction, etc., of matter and energy: physics is subdivided into mechanics, thermodynmics, optics, acoustics, etc.

What other heuristic and/or metaphysical specifications may be applied as empirical definitions of physical science?
