Just a guy, bout to get my PhD in experimental particle physics. I like hockey, basketball, DND, science, and audio equipment.

I thought I was hot shit with a low-priority B name, but the Adams in my collaboration showed me just how truly mid I am. If he wasn’t on my dissertation committee… and also a cool dude… and a good scientist…, I would have some choice words for him!
My PI has 2 walls covered in cork board in the hall outside our meeting room. Every paper we publish gets pinned there. It is the “Profesional” equivalent of getting your report card put on the fridge, we have a whole pinning ceremony and everything.
It is for your own sake. In the time it would take to utter one letter of their name, a trillion cosmoes would flare into existence and sink into Eternal Night!
I didn’t know the European Space Agency organized E3. Learn something new every day.
It is interesting, but it feels like there are too many compromises made at the expense of observational data.
The first issue is the reliance on a ~2eV neutrino to compensate. While sterile neutrinos could theoretically be that massive, we have yet to find conclusive evidence of steriles and don’t know the absolute masses or the mass ordering of the neutrinos mass eigenstates we have observed. (I am in neutrinos, so this is the point I am most familiar with.) While the discovery of steriles could occur, my buddy works on a search for eV scale sterile neutrinos and all of his findings have shown that there is no preference for any sterile signal at or around 1-100eV. Normal neutrinos also can’t work: While we don’t know the masses of each neutrino mass eigenstate individually, we know the sum of the neutrino masses, ~0.06-0.1eV, eliminating normal neutrinos from contention as well. This is a core failing, as it relies on the presence of an equally unproven particle as DM, but isn’t as good a fit as DM in many ways, leading into point 2…
It has a hard time fitting to galactic cluster data. The Bullet cluster is one of the best observational proofs of DM, and MOND doean’t offer a good explanation for what we see. It also doesn’t account for gravitational lensing, which is a problem given we can see that quite clearly. Since it is only effective at huge scales and can’t be easily checked in a lab, it needs to at least consistently describe observations before I can consider it over DM, which does an excellent job of describing observation. This leads into my final point…
There isn’t really any way to experimentally verify/refute it. I am an experimentalist, and while not every theory needs to have a labrotory confirmation, it seems like there is no way to falsify MOND. DM experiments have long proposed models that allow for some DM particle interaction mechanism, however infrequent, with barionic matter that would confirm/deny those models. While far from exhaustive, it at least allows for the ruling out of certain models if the expected flux isn’t there. MOND seems opaque to even this sort of experimental checking.
There are other issue too, but I am not well versed in GR, which is where many other tensions exist. Overall, it seems like an interesting math problem, but I can’t take it seriously until it gives us something to test or describes what we see much more accurately.
Sometimes stuff does. Othertimes, it is more open for debate. As a rule, I like to imagine that stuff might, but only if it will make stuff more confusing.
This is the truth. I am a few months away from getting my PhD in particle physics and the core questions being raised in all levels of the field at the edges of our decent big-picture understanding are so exciting.
Not just guitar audio! I own a tube amp for my guitar and 2 tube amps for driving my higher-end headphones! They are neat little pieces of electronics history, not just in how they run, but also because most of the best tubes are old military surplus. My oldest pair are from 1945 and were made for early army/navy radar systems.
Regarding not being familiar with LaTeX, I have already successfully used this template alongside chatGPT to convert items from a block of poorly formatted text to a finished card in just a few minutes. All you have to do is feed chatGPT the item’s description and the contents of the TeX files contained in the package (itemcard.tex, itemCommands.tex, tcolorboxSettings.tex) and it will do a pretty bang up job of formatting your item to match the template.
This was discounting the truly lazy ones where I just add -boy, -girl, and -cat to the end which adds an infinite supply of stupid names. We took Gyaos to a different vet than our normal one once (for a paw he cut on some glass he shattered) and they acted like Mouse was the weirdest nickname in the world. We didn’t return to them ever again.
I have in my menagerie of cats:
Gamera: Guardian of The Universe; Nicknames- Gambi, Gambini, Gamberooni, Grayby
Gyaos (pronounced Gauss); Nicknames- Gyaos-a-mouse, Mouse, Goose, Goose-a-moose, Moose
Drax The Destroyer; Nicknames- Droopy, Droops, Droopy-poopy, Drax-attacks, Drakattaka
Marceline the Vampire Queen; Nicknames- Marcy, Moops, MooMoo, Marmie, MooMoo Bean the Stinky Queen
Cookie; Nicknames- Cook, Cookie-Books, Bookie, Book
I see your Cookie and raise you a Cookie of my own.
She looks like my old puppy Annie, who we lost last year after managing her chronic kidney failure for 4 years. She even has the wonky teeth. Sweet lil visiting pup, give her an extra pet for me.
I’ll make him rue the day he was born. I will make the kerning on the copy of my dissertation I send him just slightly weird so that it gives him uncanny discomfort while reading it. Any plots I cite from his work will be slightly lower resolution. He won’t know what hit him.
