Referring to the Wikipedia Link for Mathematical Constants http://en.wikipedia.org/wiki/Mathematical_constant Can we also Add Acceleration due to Gravity g=9.80665 m/s2 as a Mathematical Constant in the Table of selected mathematical constants ? http://en.wikipedia.org/wiki/Standard_gravity Another example is Gravitational constant http://en.wikipedia.org/wiki/Gravitational_constant This are the constants used in Physics, so can they be also considered mathematical constants or it will be classified only as physical constants ? Thanks & Regards, Prashant S Akerkar

Comparison between Mathematical and Physical Constants  http://en.wikipedia.org/wiki/Physical_constant Though both are constants, A physical constant is a physical quantity that is generally believed to be both universal in nature and constant in time. It can be contrasted with a mathematical constant, which is a fixed numerical value but does not directly involve any physical measurement. Mathematical Constants used in Physics  http://www.desy.de/user/projects/Physic ... GR/pi.html For the types of nonEuclidean geometry used in physics, the ratio is very nearly ? over small distances so we do not notice the difference in ordinary measurements. This does not mean that ? changes, because our definition of ? specified a Euclidean geometry, not physical geometry. No new theory or experiment in physics can change the value of mathematically defined constants. Thanks & Regards, Prashant S Akerkar

Is there a thin line between the two comparisons i.e Mathematical and Physical Constants ? Note : Physical Constants value remain the same, they measure a physical quantity, so then does it implies that they can be also considered as mathematical constants but used in Applications of Physics viz Newton's Laws of Motion, Newton's Law of Gravity etc. Thanks & Regards, Prashant S Akerkar

Can we say "Those Physical constants whose value do not change with the environment can be considered as Mathematical constants". ? Thanks & Regards, Prashant S Akerkar
