E28 Conceptual Object in version 7.1
- Beethoven’s “Ode an die Freude” (Ode to Joy) (E73)
- the definition of “ontology” in the Oxford English Dictionary (E73) (Oxford University Press, 1988)
- the knowledge about the victory at Marathon carried by the famous runner (E89) (Lagos & Karyanos, 2020)
[explanation note: In the following examples we illustrate the distinction between a propositional object, its names and its encoded forms. The Maxwell equations are a good example, because they belong to the fundamental laws of physics and their mathematical content yields identical, unambiguous results regardless formulation and encoding]
- ‘Maxwell equations’ [preferred subject access point from LCSH] (E41) (Ball, D., 1962)
http://lccn.loc.gov/sh85082387 , as of 19 November 2012]
**explanation: This is only the name for the Maxwell equations as standardized by the Library of Congress and NOT the equations themselves.
- ‘Equations, Maxwell’ [variant subject access point, from the same source] (E41)
**explanation: This is another name for the equation standardized by the Library of Congress and not the equations themselves
- Maxwell's equations (E89)
** explanation: This is the propositional content of the equations proper, independent of any particular notation or mathematical formalism.
- The encoding of Maxwells equations as in https://upload.wikimedia.org/wikipedia/commons/thumb/c/c4/Maxwell 's Equations.svg/500px-Maxwell'sEquations.svg.png (E73)
** explanation: This is one possible symbolic encoding of the propositional content of the equations.
