# Physics Glossary

In order to speak with precision about the distance domain I’ve had to invent many new terms. I’ve tried to make them parallel to the corresponding time domain terms and to follow scientific practice of using Greek and Latin roots. These new terms are placed parallel to their corresponding terms in this pdf: Parallel Glossary for Classical Physics.

The terms below are from the Parallel Glossary for Classical Physics presented in this format: term in bold, definition, units, etymology, and in some cases a suggested symbol. Other terms in this glossary are in italics.
