Can you provide a simpler example, or even a made-up (hypothetical case) example, but in the non-relativistic settings? <br /><br />In particular, does the idea of the self-force on a point-particle electron illustrate the cancelling of infinities you are talking about? <br /><br />Do you have any further explanation or comment to offer on the second answer (the one by ``mcFreid'') here: https://physics.stackexchange.com/questions/99285/the-problem-of-self-force-on-point-charges . Thanks in advance.<br /><br />Best,<br /><br />--Ajit<br />Ajit R.

In clifford algebra, multiplication by i is just a rotation by 90 degrees, and multiplying twice by i is a rotation by 180 degrees (negation). Not to get into the topic of normed division algebras but mathematicians just invent junk they don't even understand. They make a mess and refuse to clean it up.<br />https://slehar.wordpress.com/2014/03/18/clifford-algebra-a-visual-introduction/<br />https://slehar.wordpress.com/2014/06/26/geometric-algebra-projective-geometry/<br />https://slehar.wordpress.com/2014/07/24/geometric-algebra-conformal-geometry/MD Coryhttps://www.blogger.com/profile/05342743632013663077noreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-88899781702061373242018-07-18T11:56:15.178-07:002018-07-18T11:56:15.178-07:00"The whole theory of electromagnetism is thus..."The whole theory of electromagnetism is thus the inevitable consequence of looking for a geometric theory obeying locality."<br /><br />It is well established that photons of light are electromagnetic fields.<br /><br />Are you saying that photons thus obey locality, and can never be entangled?Golden Number Ratiohttps://www.blogger.com/profile/06047804495884984100noreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-15995221086619763392018-07-18T09:59:53.057-07:002018-07-18T09:59:53.057-07:00Charge is not math.

Until you have an underlying theory that can explain what these things are besides '+' and '-' signs in a diagram, then you are diddling with epicycles. This is why physics is so screwed up, too much unassigned math.CFTnoreply@blogger.com
