lucas123 Posted September 16, 2012 Share Posted September 16, 2012 I would like to know the laws that can not be deduced from others, I know that they are many, but citing at least one is better than nothing. Link to comment Share on other sites More sharing options...
MigL Posted September 17, 2012 Share Posted September 17, 2012 It seems that at the most fundamental level, symmetries, continuous and gauge, are responsible for physical laws. Link to comment Share on other sites More sharing options...
ajb Posted September 17, 2012 Share Posted September 17, 2012 I am not sure if it is a law as such, but MigL mentions it; The Principle of Gauge Symmetry. Basically this means that physics does not care about the coordinates you chose to describe the system. Link to comment Share on other sites More sharing options...

ajb Posted October 10, 2012 Share Posted October 10, 2012 Energy conservation law. This follows from Noether's theorem, which is a consequence of the symmetry of the system. Link to comment Share on other sites More sharing options...

swansont Posted October 11, 2012 Share Posted October 11, 2012 I would argue that a law that has restrictions on it, such as elastic collisions only, cannot be considered fundamental. Link to comment Share on other sites More sharing options...

The Observer Posted November 4, 2012 Share Posted November 4, 2012 Conservation of Momentum of Elastic Collisions Conservation of Kinetic Energy in Elastic Collisions (same as above) Newton's Planetary Motion Formula These too are a consequence of Noethers theorem, as are all conservation laws. Symmetry seems to be the fundamental concept. Link to comment Share on other sites More sharing options...
