Feynman

BTW I imagine the late Dr. Feynman as one of the majority of physicists who don’t understand QM but also don’t care enough to worry about it. I saw some of his lecture statements today and they were of the ‘I don’t understand this and don’t think anyone does’ variety, without any ideology laden upon that. Also his own contributions to physics are renowned for their contrived character and desire mainly to get the answer as easily as possible, from what I have read.

As so often is the case, it’s the philosophers we really have to worry about. (For this dispute, their main technique is Special Pleading. I think d’Espagnat was illustrating the method at its finest, though for some reason he wrote in florid free verse.)

My brain pain, and my back pain

Hofer’s argument in geometric algebra can be more intuitively given in the conformal model of space and by using coordinate systems less. Also his presentation uses questionable (though probably not uncommon) GA terminology and has at least two ‘shortcuts’ given without explanation. I plan to reformulate, as soon as I figure out one or two things. Well, really, it’s how best to fill in one of those shortcuts.

Meanwhile I have back spasm. Not fun.

On the other hand, the burn on my arm seems to be healing.

Misfortune

Unfortunately, if I get this right, I still won’t write a paper, due to my disability. I’ll just make a summary available to people who can write papers. We could use more laypeople writing scientific papers, though.

The difficult part, which I have not seen done by anyone, is how to make correlation due to phase more intuitive without forcing the reader to revert to the mind-picture of a classical field. Little known may be that it is insufficient to produce the right numbers; you must convince with geometry. This goes against the romantic picture of ‘self-correcting’ science; the force of your argument depends on how you speak.
