So a change in the reference frame should have no impact on the physics. Maybe he forgot, that the angular momentum is a second-rank tensor in SR and so a spacial contribution to the 3D-angular momentum could be created just be changing the reference frame.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-34480619.post-61546217992842049772012-05-03T13:59:09.335-05:002012-05-03T13:59:09.335-05:00So, I've just read the paper.

I would argue that bound current loops are unphysical on the level of classical E&M because a charge actually moving in a loop should radiate, and a system with some static magnetization M does not do so. What do you think?Douglas Natelsonhttps://www.blogger.com/profile/13340091255404229559noreply@blogger.comtag:blogger.com,1999:blog-34480619.post-14564868291702701672012-05-03T09:08:39.249-05:002012-05-03T09:08:39.249-05:00The article may present "incontrovertible the...The article may present "incontrovertible theoretical evidence of the incompatibility of the<br />Lorentz law with the fundamental tenets of special relativity", but the evidence certainly isn't transparent. I can't believe that a PRL referee would recommend acceptance without requiring it to be presented in a manifestly covariant form. The vector notation has its place, but not when arguing about fine details of Lorentz covariance or otherwise of some piece of mathematics.Peterhttps://www.blogger.com/profile/08654675777726560464noreply@blogger.com
