Just read his vector/scalar paragraph. Good stuff. Not seen anything this stupid in a long time. Do you want me to tear his stuff to shreds line by line or shall we just leave it that it is nonsense?
What's really funny is when he does state something correct, he claims that no-one knows it, except possibly Feynman. What an idiot.
What the present vector system of EM does, therefore, is throw out the ability to use the very strong EM force as an agent to curve local spacetime. The very mathematics itself, a priori, assumes and guarantees a locally flat spacetime.
Hmmm, so I guess I've never studied Einstein-Maxwell theory? Never taught the Reisnner-Nordstrom black hole? Strange...
In fact, it can be shown that the E-field and B-field do not exist as such in vacuum; only the potential for the E-field and the B-field exist in vacuum. Feynman pointed that out, but nearly all of his modern cohorts seem not to have recognized that fact.
Strange, I can pull out just about every grad text on my shelf which will say this. But then, they're probably a bit over his head. What's even funnier of course is that it isn't actually true if you allow non-trivial topology... as our friend Wheeler was so fond of pointing out.

Re: Quantum mysticism
I happen to have owned the An. Cosm. Principle since it came out
Ditto. There's a lot of good stuff in there, but Tippler has always been a bit dubious with his mystical side. I think some it rubbed off on Barrow

Re: LOL
Hmmm, not sure how to take that Certainly not that (in)famous! He seems to have done well now though with his move to my old home (DAMTP-GR). I guess I have my dubious side too but it tends to only surface with my anonymity here...
Good to hear from you BTW. We seemed to just miss each other in activity here at EvC. Funny, reading back over your old posts I used to think you were a little abrasive at times... and of course finding myself becoming exactly the same way after 10 months of posting!

Uh-oh, anonymity under threat
When? Particles, GR or Astrophys?

Re: LOL
Understood and no problem. Given your speed of response, I can at least dismiss one possibilty

Re: LOL
Who else... but you're not abrasive enough either!
No, I'm pretty much pure QG, either via strings, TQFT, quantum cosmology, etc. And no, sadly I left long ago. Have done many things since, but will always be an undying passion. I still try to keep up with hep-th and gr-qc...

Re: Getting way Off Topic
Sure Jar But I'm late for a dinner appointment so it will have to wait a few hours... bye for now.

Re: LOL
Sorry Eta, will have to come back to this later tonight (in a new coffe house thread as per Jar's wishes)
Are you back or is this just a fleeting visit?
