So what makes a neutrino oscillate: forces internal to the neutrino alone, internal forces reacting to external forces, external forces alone, or combinations thereof?
If it's related to mass, some mass-energy must be added from somewhere, or dumped off to somewhere, right?

Neutrinos caught on camera: Testing the first prototype of a new elementary particle detector

Some innovations in physics come from entirely new technologies, others from fresh theoretical insights. Others still take shape by bringing together existing tools in new ways, working out how to combine them to outperform other solutions. The branch of particle physics that studies weakly interacting particles—such as neutrinos and some types of dark-matter candidates—could use innovative detection approaches: technological challenges in this research area quickly become practical as well as economic, as increases in detector volume and spatial resolution improve the sensitivity to the processes producing the particles of interest. Similarly, demanding targets on instrument capability apply to the calorimeters used in collider experiments.

The #paperOfTheDay is Wolfgang Pauli's letter to experimental physicists Lise Meitner and Hans Geiger in December 1930. Pauli explains that he is unable to join their meeting due to a ball event in Zürich, but still wants to inform them about his newest theory.
At that time, beta decay had been well confirmed experimentally, but the energies and momenta of the observed particles did not add up. This had puzzled physicists to a degree such that Debye, quoted by Pauli, said "Oh, better don't think about this at all, like about new taxes!".
Pauli now proposes that there actually is a new type of particle that has so far escaped observation, which he calls "neutron". He makes some brief comments on the mass and interaction of such a particle. He will as of now not officially publish these since it is pure speculation and there is currently no experimental evidence for this particle. Instead, he has written this letter to the experimental physicists, which ends "Also, liebe Radioaktive, prüfet und richtet!" -- "Hence, dear radioactive [ladies and gentlemen], scrutinize and judge!"
A few years later, Fermi developed a full theory for Pauli's particle, and renamed it into "neutrino". The direct experimental confirmation of the #neutrino is tricky, and would take another several years. Conversely, the nuclear constituent particle we now know as "neutron", was experimentally observed already in 1932. #physics #radioactive

Deep in #Antarctic ice, these particles can answer basic questions about the universe
#IceCube can’t directly see the enigmatic #neutrino #particles, but its thousands of sensors can detect what happens after they interact with matter. When they do, the neutrinos produce charged particles that travel through the ice at nearly the speed of light, creating a blue glow called Cherenkov radiation.

Record-Breaking Neutrino May Be Linked to Exploding Primordial Black Hole

In 2023, scientists observed a neutrino hitting Earth with an energy level far beyond any known natural cosmic source, about 100,000 times greater than the output of the Large Hadron Collider.

Velo Orange Neutrino – New Bike Day

Go small, go simple, go now. Wise words spoken by a sailor of the old days. Still, it applies to everything we do in this life. All told we have been living in tiny Airbnb’s almost exclusively for 4 years. We did have an 8 month stint in a hotel to be close to the boat but it was just too simple for us.

A centimeter here, a few degrees there… this bike is fitting better and better every day. Zero would be the number of complaints I have at this point. I should have a Frame bag made but I just can’t commit to it. Bar bags, saddle bags, feed bags, who knows. I always dive in on day one but with this little Kermie bike I just keep slowing down. The frogs awaking is always the first signal of spring. On my first ride with the new Neutrino they sang their song all along my first creekside ramble. Maybe nature has named her for me.

Here are the Velo Orange Neutrino build specs:

Crankset: Microshift Sword Black, 42T
Bottom Bracket: VO English Threaded, 113mm
Wheels: VO Disc Hubs laced to 20″ Velocity Cliffhanger Rims
Tires: Maxxis Holy Roller 20 x 2.2
Handlebars: VO Klunker
Shifter: Microshift Advent 9 speed
Rear Derailleur: Microshift Advent Super Short, 9 speed
Cassette: Microshift Advent 11-38, 9 speed
Chain: KMC X9
Brakes: Growtac Equal, Post Mount
Brake Rotors: Promax 160mm
Brake Levers: Origin 8 Midi-Trigger
Seatpost: VO 31.6, Medium Setback
Saddle: San Marco Selle Sportive
Grips: VO Foam, Black
Pedals: Blue Lug Bear Trap Pedal by MKS

I ride every day now, but first I walk. There is something about walking my dog that is so good for the soul. She sniffs and explores every inch of the village like it was her first time. I feel the same way on my bike. It doesn’t matter how many times I’ve ridden down this trail or that. It’s always new and fun to me. Yesterday I saw a Mink. One day I found a snake in a tree, a whole new level of fear was born with that one. Birds of prey are everywhere. If you look often enough you will see whales splashing around and playing just as hard as I do.

I’ve had my little Neutrino for 6 days now. I made 2 videos about her. Each piece has been unfastened, greased and retorqued to proper spec. None of this needed to be done but that’s how I get to know the workings of each new bike. Unlike the Brompton all parts of the Neutrino are standard making this a super easy bike to work on. Now I need to build an apocalypse kit just in case.
