I assume this result was from a run with ordinary hydrogen, no deuterium or tritium. But I think the equivalent DT values are frequently calculated. Is this possible here? TIA again

Why no new data? No news of any problems that I have heard. I'm both mystified and concerned. Jim Graber

Thanks for the references. It is somewhat clearer to me now, particularly in the context of entanglement.

So, please, what is the difference (in math and in words) between "the Photon is V-Polarized along axis X" and "if we measure the polarization along angle x the result will be V" ? Thanks jim Graber

How much tension between recent AMS-02 80 Gev dark matter and Lux-Xenon negative results? Recent results ( Arxiv 1610.03840 and 1704.08258) suggest a WIMP dark matter particle near 80 Gev. See also https://phys.org/news/2017-05-possibility-cosmic-rays-due-dark.html If this particle really...

In addition to pB, there is also DHe3. Helion Energy plans to use this fuel

At one point they were supposed to be running with plain ordinary hydrogen now, leading up to deuterium and tritium next year. Have they even restarted the plasma runs? I am pretty sure they are done building (or rebuilding) the beryllium and tungsten based "iter like wall" Woops, Google says...

http://www.pppl.gov/news/2016/09/pppl-director-stewart-prager-steps-down It appears that Stuart Prager is “stepping down” as director of PPPL. I wish him well. But in the announcement it refers to a “recent technical setback in the NSTX-U facility”. I had not heard previously of this set...

https://arxiv.org/abs/1405.3483 Steven Weinberg Quantum Mechanics Without State Vectors In this paper, SW proposes a formulation of QM based solely on density matrices. Does this solve the problem? How is it similar or different to the AN formulation? TIA Jim Graber

Oh Yes. I was thinking of the range, not the domain. Is that C^3N? Or Only R^3N? Or sometihng bigger and more complicated? TIA Jim Graber

Is it R^3N or C^3N? And does this make a difference as far as realness or physicality?
