EXPLANATION OF THE GLOSSING SYSTEM
(to understand how I describe the signs in this dictionary).

For content knowledge of how to use the physics terms in context, see Guided tutorial in physics for interpreters.

For negotiating and developing temporary signs, see Preparation and sign negotiation

For vocabulary lists to determine helpful signs for a specific discipline, see Vocabulary lists by topic.
