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!
Rant about people like this incoming:
I am a few months away from defending my PhD in Particle and Nuclear Physics and this is such an omnipresent issue with many of the people I interact with regularly. Poorly paraphrasing Dan Olson of Folding Ideas: Because they understand one really complicated subject (particle physics), they see all other subjects as lesser, easily understood and interpreted through the lens of their area of expertise.
I know at least one professor, well respected in his field, who is a vaccine conspiracist and happy to tacitly endorse right wing conspiratorial thought, despite being an expert on mathematical modelling of complex systems. He should understand the rigor involved in modelling and solving a problem like covid, but instead assumes that because it is complicated, the immunologists and virologists must just not be able to arrive at a conclusion he deems good enough to challenge his simplistic view of the situation.
Many professors, however well intentioned, try and reduce labor issues to math problems instead of considering the human element that is really the core of the problem. They build their perspective around explotative capitalist rhetoric, even when graduate students are struggling to afford food and rent. Then they turn around and wonder why enrollment is declining and pursuing academia is falling in popularity
People like Sabine and these professors I have dealt with loudly perpetuate whatever worldview they already hold, assuming that because they must be intelligent enough to grasp difficult math and physics concepts, they couldn’t be ignorant enough for their unrelated ideas to be wrong. It is infuriating because it adds a unearned veneer of authenticity to the concepts, despite a transparent lack of knowledge. Then there is feedback, where people use this support as their evidence for embracing these ideologies and as a building block for furthering their agenda.
These people are also, generally, stale in terms of their own academic output, for I think the same reason as their uneducated takes on other topics. They assume that they understand what they need to and stop grasping for better understanding. My PI is constantly seeking out new experiments to get involved with to try and widen his understanding, and is also a great proponent of progresssive issues. I don’t think this is coincidence. My scientific role model, another advisor of mine, is trying to develop a better academic system that would make education on the most pressing issue today (global warming) better included and more competently taught in university curriculum, regardless of degree topic. He seeks out as many opinions from students and experts as possible in furtherance of this goal. This is despite being one of the key innovators in our field, where his word might be taken as gospel, but because he hasn’t lost his fundamental curiosity about the world, he still seeks out more informed opinions in this endeavor.
The really great scientists keep this curiosity and question their own expertise constantly. The Sabines of the world become comfortable in their own knowledge, and by extension, their own ignorance.
And by that, you mean using heart-sized servings, right?
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.
Someone who understands. I have never seen a recipe call for x cloves that wasn’t infinitely better with 5x cloves.
Just noticed that you chose the nicest kernel size. Even better.
Ah, you’re right, I haven’t taken Stat. Mech. in almost 5 years so my brain just latched on to the general form. Analysis in frequency space is always fun
Another nice way one could preserve the complex data when visualizing it would be to make a 3d color mesh and display the imaginary components as the height in z and the real component as the color scale (or vice-versa).
Edit* now I am trying to think if there would be a clever way to show the abs, Re and Im values in one 3d plot, but drawing a blank. Maybe tie Im to the alpha value to make the transparency change as the imaginary component goes up and down? It would just require mapping the set of all numbers from -inf:inf to 0:1, which is doable in a 1-1 transformation iirc since they both have cardinality C. I think it would be
alpha = 1 - 1/(1-e^{Im(z)})
Which looks a lot like the equation for Bose-Einstein statistics in Stat. Mech. I was never very good at complex analysis or group theory though, so I don’t really know what to make of that.
Apply a nice gaussian kernel convolution to the fft and smooth that doodle out! Lets get blurry up in this doodle party!
My table’s necromancer has a homebrew staff formerly belonging to a mummy-priest that allows him to cast destroy water, and it becomes an at will spell if used on a corpes to mummify it. The demon lord of drought and the patron of mummifcation demands it.
It allows for convenient storage and transport of the corpses he …procures…
Totally lost my sense of smell for about 2 weeks, but it came back pretty quickly. The worst long term symptom has been a substantially heightened gag reflex. Talking while chewimg gum has become a balancing act or I start heaving, just brushing my molars is enough to trigger gagging some days, and brushing my tongue after my teeth is a sprint to avoid puking. It’s trash.
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!
An old granny bard, based in no small part on my own grandma. She doesn’t channel her magic through song or dance, but through her sassy remarks, telling stories about her childhood, and making baked goods, sweets, and presents for her adopted grandkids (the adventuring party).
Bardic Inspiration? Reminding you how much she loves you and is proud of you. Alternatively, giving you some candy for later or promising that if you do well, she will bake you a pie or take you out for icecream for being so brave.
Healing spells? Blown kisses, band-aids, and warm cookies.
Hypnotic Pattern/Hold Person/etc? Telling a rambling story (that she forgot what the point/moral was before she even started) but the enemies are too polite to interrupt her.
Dissonant Whispers/Visious Mockery/etc? Asking when you are going to get a boyfriend/girlfriend, graduate, get married, or get a real job. Telling bad (and slightly innapropriate) jokes, for her own amusement, often messing up the punchline. Asking if you have talked your mother recently (“You know, she won’t be around forever, and I am sure she wishes you’d write more.”) Simply saying “Bless your heart.”
Party Buffs? Giving you knickknacks, homemade gifts, or old hand-me-downs she really thinks you’ll like. Passing down age-earned wisdom and giving encouragement to just try your best. Making breakfast for the party, using far too much butter, cream, and other artery clogging goodness.
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.
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.
