Ten total presidential aircraft and four you can walk through at the Dayton USAF museum [1]! You can walk through SAM 26000, the VC-137C used by 8 presidents including Kennedy. Amazing collection. [1] https://www.nationalmuseum.a

Just to add for reference, the strongest bounds (for any NLDBD candidate isotope) are from KamLAND-Zen using Xenon-136, also last year: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.13... .

If there's a prior in the community, my impression (as a neutrino physicist) is that if anything it's more toward Majorana than not, in the absence of evidence either way. It is surely nicer from a theory perspective, with a (sees

I am curious why the door plug is not a plug door — that is, a design wherein the desired panel would be installed from the inside and sealed by the differential pressure, like a cabin door. This part looks more similar to cargo door; those

+1 for GeoWorks which ran a lovely suite of bundled programs amazingly well on a 286, and was preinstalled alongside MS-DOS on some systems in the early 90s. Despite being a quality product, apparently development was a major pain (expensiv

Another perspective on this is that departments will have a long term hiring strategy that balances breadth of the overall research program against depth in a particular subdiscipline, with the goal of building a coherent ecosystem with goo

Even better, the actual in situ delays are measured and compensated for, and it works independent of the physical connection (and through fiber/copper, switch layers, etc.).

It's also assumed that "i" is an integer, a contextually plausible but potentially bad assumption. By one interpretation of the prompt, foobar(9) should print "yam" but foobar(9.5) still "baloney", for exa

It's not quite so bad, with many experiments looking at solar or atmospheric neutrinos seeing hundreds to thousands of neutrino events per year. Experiments at particle accelerator-based neutrino beams can see much larger event rates d

They are primarily coming from neutron capture (electron + proton -> electron neutrino + neutron). During much of the collapse even these weakly-interacting neutrinos get trapped behind the high-density shock wave. As it expands and the

I am a physicist working as a physicist! My field of experimental particle physics, at least, is very hacker-ey: we develop instrumentation hardware, low-level data acquisition software, database and web apps for experiment operations and m

It's really interesting work! Just a year or so ago, the features in the energy spectrum appeared to be independent of burn-up, so it's exciting to see higher precision data coming in. No matter what, we'll get a much better

The other comments are spot-on. I'll just add that the neutrinos flavors are defined by the way they interact: electron neutrinos interact to produce electrons, never muons. So they're quite different in that sense, and in the cur

Hi, neutrino physicist here. There are indeed a handful of results that point to a more-or-less consistent picture with sterile neutrinos, including MiniBooNE (now updated with 2x more data), LSND, antineutrinos from nuclear reactors, and c

I'd be curious to know whether there was any context given with Nathalie's exoneration. For example, "it was invented by her jealous peer" rather than just "it wasn't true." Might the revelation of decepti
