Hi,all, I am wondering, momentum can expressed as energy, so:(adsbygoogle = window.adsbygoogle || []).push({});

dxdP can expresses as dxdE ???

then position, momentum, energy,time are all related, and they all form uncertainty relations??

in the view of commute the operators, all these four operators can NOT commute??

where am I wrong?

Thanks in advance!
