Where Photons Have Been: Nowhere Without All Components of Their Wavefunctions
A nested interferometer experiment by Danan et al (2013) is discussed and some ontological implications explored, primarily in the context of time-symmetric interpretations of quantum theory. It is pointed out that photons are supported by all components of their wavefunctions, not selectively truncated "first order" portions of them, and that figures representing both a gap in the photon's path and signals from the cut-off path are incorrect. It is also noted that the Transactional Formulation…

Letzte Woche ist Thomas Keck gestorben - Barbara Eder erinnert an ihn, indem sie auf ihrer Homepage den Mitschnitt einer von ihr 2013 an der Universität Debrecen organisierten Lesung zur Verfügung stellt. Thomas #Keck las damals erstmals in Ungarn über Werk und Leben von Ronald #Schernikau:

Dar viena detalė man įdomi iš Batkolucko tyrimo: ~2013 m. web svetainė už 37k LTL. Kiek ekrane rodė, ten panašu į vieno puslapio landing page.
Mano atmintis neretai prastesnė už premjero, bet lyg ir kainos žemesnės buvo tuo metu? Ypač jei startupas moka suktis.

The nuclear surface diffuseness effects on the alpha decay of heavy and super heavy nuclei
We select 300 different parent nuclei in the range Z from 64 to 106. The proximity potentials Zhang 2013 and Guo 2013 are employed to calculate the nuclear potential. The influence of the nuclear surface diffuseness is applied in the calculations of interaction potential between the emitted alpha particle and daughter nucleus through the reduced radius parameter. The systematic analysis of the radial behavior of interaction potential with and without the surface diffuseness effect reveals that …

For some reason YouTube decided I'd be interested in this video I already watched many many years ago: https://www.youtube.com/watch?v=oo_7s4TrL28
I saw it in person in at The Troubadour in LA in 2013. I wasn't aware of it - just there for Little Boots, and was very impressed. It was …
