Operating Principle (Physical Description)

Definition:

Observations:

1. The operating principle refers to the mechanisms, processes and physical or chemical principles that govern the operation of the object.
2. N.B.: Do not confuse the Operating Principle field with the History of Use field. The Operating Principle field contains a brief description of the operating mechanisms of the object, whereas the History of Use field contains information on the different uses of the object.
   Example

   A Gregory telescope used for stargazing

   	Object Name	Gregory telescope
   	History of Use	stargazing
   	Operating Principle	The image is reflected in the first mirror and then in the second, where the image is inverted, before being reflected into the dual eyepiece.

Entry rule:

• The Operating Principle field is particularly useful when information is entered clearly, concisely and consistently.
