Baez writes to Firth: I already told Robert this. Perhaps I wasn't sufficiently eloquent to get my point across. But let me just say that I agree completely with Benjamin Weiner's point. It makes perfect sense to argue about what can or cannot happen according to orthodox QM without doing any experiments. If Sarfatti claimed he had a NEW THEORY that contradicted orthodox QM one would have to see if his theory was consistent and met experimental tests. But he seems to be claiming that orthodox QM predicts FTL communication. Of course, his way of doing orthodox QM looks very unorthodox, i.e., wrong. This indicates to me that Baez does not understand orthodox quantum mechanics. I am willing to retract my statement if Baez can pinpoint the deviation of my argument from orthodox qm. The red herring that |a,e,+> is orthogonal to |a,o,+> is hogwash and contradicts standard QM and is not required by local unitarity of time evolution between measurements. Thinking that they are orthogonal shows a lack of physical understanding. A half-wave plate rotates plane of polarization by 90 degrees. Therefore, although |a,e,+> is orthogonal to |a,o,->, it is not orthogonal to |a,o,+> and this is not a non- unitary transformation. The unitary transformation is U(1/2)|a,o,-> = |a,o,+> U(1/2)|a,o,+> = |a,o,-> U(1.2)|a,e,+> = |a,e,+> H(1/2)|a,e,-> = |a,e,-> (typo H last line is U) <a,o,-|a,o,+> = 0 <a,e,+|a,e,-> = 0 <a,e,+|a,o,-> = 0 |<a,e,+|a,o,+>| = 1 |<a,e,-|a,o,->| = 1 If Baez has another objection what is it? Baze is a good formalist, perhaps. But he totally lacks the physical understanding (i.e. Bohm's "informal language") that connects the formalisim of kets and unitary matrices to the physical devices. The same goes for Ramsay and Weiner. Formalism is like "statistics" you can prove all kinds of lies with it - and then you can abuse your opponent by calling him "crackpot" or saying the work is "nonsense". I am not accusing Baez of the latter - I refer to others. As Einstein said:"Great spirits have always encountered violent opposition from mediocre minds." Baez, I am not referring to you here - but to some rude person from Skidmore College physics Dept who sent me a gratuitous malicious and very unprofessional e-mail.
