In addition, we also discuss some issues given by Roland Omnes in “Understanding Quantum Mechanics” as to the problem of classical and quantum properties, which is at the forefront of the Quantum Gravity issues of how to reconcile semi classical physics with the presumed bridge between Planckian physics (presumably quantum in nature) with the rest of cosmology. The issues argued in part by the Solvay meeting as to Quantum measurements and the competing Pilot theory, as brought up by De Broglie, and how that plays out as to the later Hidden Variables and the alleged determinism foundations of an embedding structure for Quantum physics, still are with us, and make the Solvay meeting, 1927 a stellar event, still worth revisiting 90 years later.展开更多

The percent extraction ofthorium was studied as a function of acidity, PMBP concentration and equilibrium time. The back-extraction behaviorof thorium from the organic phase was also tested. Separation of thorium was performed from fission products pro-duced in 14 MeV neutron bombardment of natural uranium by employing the PMBP extraction procedure. Thegamma-ray spectra of the separated thorium fractions show that thorium can be separated from most of fission prod-ucts and a large amount of uranium.展开更多
