|Constants, philosophy, logic: constants are conditions which do not change, in contrast to processes, states, and also natural objects, e.g. aging. An aging human being remains constantly the same person, but not the same body. For a constant, e.g. a name for an object is given. Letters of logic are given for individual constants (a, b, c ...), but also for individual variables (x, y, z ...). Variables are not changing objects, but a new object may be used instead of a variable, e.g. 4 instead of 5. These two numbers, however, are not changing objects, but have a constant value.|

Constants/Hacking: we use them mostly to determine the quotient between two constants.
The redefinition and better identification of constants never comes to a conclusion. This is not a "continuation of the theory by other means".
Constant/Constant of Nature/Hacking: the value of a constant is not part of the theory. - Most of them are connected with other constants by physical laws. - The gravitational constant is connected with nothing else.
Duhem: qualitative fact: that the universe can be represented by certain mathematical models - further qualitative fact: that there is a number that goes best with our mathematics.
Hacking: we use constants usually to determine the quotient between two constants. - We reach no end to the improvements.
