Electron Affinity, open sites, and new more precise sub electron volt cameras and sensors

Measurement of the electron affinity of lead and its isotope shifts at Physical Review A @PhysRevA 3h Letter: Measurement of the electron affinity of lead and its isotope shifts @DenisonU @vassalloef Replying to @PhysRevA @DenisonU and @vassalloef Looks like a lovely and precise study. I have been following “electron affinity” for years.

Twitter APS pay per view

The Internet, even on Twitter, is for everyone. Every person in the world should have access to global tools, data, models. Always include the open link. If APS cannot stay in business otherwise, tell me why.   Nice paper, needs shared symbolic simulator. Collective effects on the performance and stability of quantum heat engines

Twitter to yet another open access group about the need for a live, open, complete, collaborative map

Replying to @APSphysics @IOPPublishing and 3 others Your groups’ policies and ideas are mostly correct, but your Internet footprint and methods are a mess. “open access” has 524 Million entry points today on Google search. And your group is just adding, badly, to that mess. One live, open, complete, collaborative map would help.

Twitter to Sony about lossless formats for global sharing of science data

@Sony Sony donated an Alpha 7S for a live webcam at Maunakea Subaru Telescope. Could Sony also help promote better Internet standards for lossless video? Look at these poor star pixels. Live stars need lossless formats. Global sharing for science data.  

Posted on my Facebook about Olbers paradox and an infinite universe

You might never have heard of “Olber’s paradox”, but it is one of those perennial provacative items that gets served with most introduction to physics and astronophysics classes. For the lecturer to strut their stuff and appear learned. Olber is Heinrich Wilhelm Olbers (1758-1840) and the link is I like to watch the night

Twitter about lack of teachers for Texas – Lifetime learning for everyone is possible and desireable

Texas Tribune @TexasTribune 13h Texas has had a teacher shortage for years. However, a number of recent issues have placed teachers at the front lines — and are pushing them to their limits and out of the job. Here’s what you need to know: Replying to @TexasTribune Your 2020 Texas pop is 29.6 M.

Twitter simulation of fluids stirred by pointed paddles

Physics Magazine @PhysicsMagazine 8h Simulation videos illustrate how changing different parameters of the system alters how well two fluids mix together when stirred. (For the stirrers, tadpole and teeth shapes are best). Read the story by @astrogasparini. Replying to @PhysicsMagazine @PhysRevFluids and @astrogasparini Effectively Mixing Two Fluids at If only the simulations

Tweet about levitated nanoparticle

Physical Review Letters  @PhysRevLett Jul 25 A trapped nanoparticle interacting with a laser provides a simple way to generate squeezed light which has an unusually low level of fluctuations. Letter: Letter: Focus: Extra-Stable Light Produced by Levitated Nanoparticle How long can the nanoparticle be monitored? Can you track it closely for
