【探讨】energy is not conserved i’ve been meaning to link to this post at the arxiv blog, which is a great source of quirky and interesting new papers. in this case they are pointing to a speculative but interesting paper by martin perl and ... 分享 5 赞 花落殊熙吧 花落殊熙 !!
That means, velocities (or momenta) are considered individual DOFs, and not that each pair of coordinate + velocity make up only one DOF. Time is no DOF however, it is a parameter. Please discuss this in this question if you disagree. mathematical-physics symmetry noethers-...

The corresponding conservation law is at the heart of physics, it cannot be subject to definition. Rather, all the definitions of the SET eventually must have the same meaning. For the Einstein-Hilbert plus matter action, in union with the postulate that the metric itself is the dynamic field...

Biologists believe that their common ancestry is why the structure of mitochondria is "conserved" in eukaryotes, meaning that it is very similar across different species—from the simplest to most complex organisms. Now, it is known that as cells divide, so do mitochondria, but exactly how ...

The multiple reduction process of the (4 + 1)-Fokas equation through the Lie algebra spanned elements, and the corresponding optimal system guarantees 23 solutions in general forms. To determine the physical meaning of the latter, an appropriate ansatz for the arbitrary functions and parameters ...
The sci.physics.faq on energy conservation in GR is at http://math.ucr.edu/home/baez/physics/Relativity/GR/energy_gr.html This is probably the link that Lurch was thinking of. I'll quote part of it to attempt to motivate people to read the entire link: Is Energy Conserved in General...
