Such amazing news. She’s been bedridden due to long Covid. Got better a few times but after a while attacks came back. Both she and her husband showed great strength. So happy to see a new milestone.
Dianna got better sometime last year as well, just in time to fly home to Hawaii for her father's funeral (yeah ...), but she got a lot worse again later. I really hope things will keep going well for Dianna now.
Props for her husband who's been incredible of taking care of her.
Is this long Covid or depression or Major Depressive Disorder (MDD)? Because in her earlier videos she talks about becoming bed-bound again due to her emotional state after finding news her friend who had a similar condition died.
Long Covid and ME/CFS can make you fragile. At least it has for me. I never used to get emotionally overwhelmed, now I do. I don't have it as bad as she does, but I've been bedbound because of this. And being sick for months to years, already leaves you feeling on the brink of depression.
I can't remember where I heard of it, but decades ago there was another neutrino detection center, also in Japan I think, that had those vacuum tube detectors, but care wasn't taken in systems design. One of them broke and the implosion caused the neighbors to break. Leading to a catastrophic of almost all the sensors! I feel bad for them, I'm sure someone here knows the exact name and date. But man, what a tough lesson to learn.
Edit: on another note, way to go on your recovery Diana. We've been rooting for you.
It's really cool to see her back and making videos again.
After seeing her status updates 2 years ago I was honestly really concerned she would be gone for good. It sounds like she had a serious case of myalgic encephalomyelitis brought on by Covid.
Part of why we know so little about these types of conditions is they are incredibly unfair. Women are 4x as likely to have some sort of constant fatigue disorder as men, and you see this reflected in literature going back centuries when describing women who just flat out disappear from public life.
One of the things about being bedridden for a long period of time is that there is a high risk of becoming more or less permanently bedridden. Especially if you have a chronic fatigue syndrome, you become weaker and any activity can retrigger fatigue. So her pushing herself to make new content sustainably is important very encouraging.
One of my favorite bits of astrophysics trivia is that the neutrino detection experiments serve as an early-warning system for supernovae, to allow astronomers to prioritize telescope time and swing the scopes around to see the first visible-light and radio signals of the event.
This is because the electromagnetic energy of the supernova can take hours to force its way through all the star's mass to the surface when the core dies, but the gravitational crush turning protons and electrons into neutrons releases a massive burst of neutrinos in every direction. And the neutrinos are so weakly-interacting with the matter in the star that they get out first. Then, a million years later, arrive in our solar system at such a high fraction of lightspeed that they presage the coming electromagnetic shock-front because the constant difference in escape time between neturinos, which are particles of matter, getting out of the star without interacting with anything and the electromagnetic waves moving through the star's matter at a fraction of lightspeed created a gap that the light never caught up to.
Can confirm - worked on Super-K as a grad student and a regular part of shift work was to go through simulated supernova alert testing. Was always kind of fun, in the lotto ticket sense (alarm goes off, review to see, ah yes, simulated test, back to shift monitoring).
I think Super-K is the place with water so pure that it will leach pretty much anything which was discovered when one of the tech's hair got wet while leaning over the water. The hair looked bleached after it went into the water. My googlfu is not finding anything to confirm though
The uncertainties about the masses of the various kinds of neutrinos are very high.
Also their abundance in the Universe is much less accurately known than for electrons and nucleons, because many processes generate neutrinos or antineutrinos and only few of those are absorbed in later collisions, so the total amount of neutrinos and antineutrinos is increasing continuously, even if the difference between the number of neutrinos and antineutrinos varies only little.
For the mass of nucleons and electrons one can make reasonable estimates, even if the uncertainties about the densities of interstellar and intergalactic matter are also very high. On the other hand, for the mass of neutrinos + antineutrinos the uncertainties encompass many orders of magnitude.
The detectors of neutrinos can detect only high-energy neutrinos. There may be much more undetectable low-energy neutrinos.
When I tried to look myself it was about this waffly but I’d also note that they were all talking about neutrinos at rest. But they’re wizzing around at relativistic speeds which makes them all many times heavier doesn’t it?
Between things like black holes and neutrinos I wonder how much Dark Matter will end up being dark matter. And I think the cosmological crisis indicates we are measuring space curvature wrong somehow.
Like neutrinos interact with gravity, which means they can be lensed, and ejected from pulsar and black hole jets. And particles moving faster than visible matter would pass that matter and accelerate it, increasing blue shift and decreasing red shift the farther you are from the source.
The video mentions that this image was taken during the night time. If the neutrinos do not interact with the entire Earth on their way through, then how do they interact with the sensor?
The Neutrino collector bit was interesting, but the best part of this video is seeing the joy in her eyes educating the rest of us about science again.

(caution for those currently sick as it's a rough watch at first)

The universe is a profoundly wild place.
It's the reverse problem: because the water is so pure it easily gets contaminated by minor things. So all the equipment has to be carefully cleaned.
