The GetConstants() command returns an expression sequence containing the symbols of the physical constants in the ScientificConstants package.

The GetConstants( 'names' ) command returns an expression sequence containing the full names of the physical constants in the ScientificConstants package.

The GetConstants( 'derivedfrom'=Const ) command returns an expression sequence containing the symbols of the physical constants that are directly derived from the constant of name or symbol Const.

The GetConstants( 'names', 'derivedfrom'=Const ) command returns an expression sequence containing the full names of the physical constants that are directly derived from the constant of name or symbol Const.

The sequence of names or symbols is sorted alphabetically.
