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

Go Nuggets! Go Avs!

  • 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.






  • It is interesting, but it feels like there are too many compromises made at the expense of observational data.

    1. 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…

    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…

    3. 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.








  • It was funky and felt distinctly un-LaTeX with the pdf cropping and graphic declarations, but was super fun. Way different from academic writing or even hobby typesetting with normal, pre-made classes (the DnD 5e LaTeX Template by rpgtex is a gamechanger for homebrewed dnd content and was the catalyst for this). The standalone document class is really weird to work with, and using tcolorboxes as the main document content feels like I am fitting a square peg into a non-euclidean hole, but it is still working!

    I am just glad I decided to use LaTeX and not python for this.



  • LaTeX is a typeset that is written in plain text with Markup language. Word, docs, acrobat are all WYSIWYG (what you see is what you get) editors, so you type the words and use toolbars to edit formatting. In markup, what you write is what you get: you type everything, including the commands for alignment, spacing, etc. It makes control and customization of your document easier. If you ever have tried to use MS Word to make a good looking equation and wanted to die when it messed up your images and spacing 10 pages back, markup typesetting is the solution.

    My tip would be to find a few templates on overleaf that you might find useful and just mess around and try to come up with what you want to see. Could be for work documents, could be for a hobby, whatever. Overleaf, the website I shared this project on, is great because it handles the backend stuff like compiling, software installs, etc. and allows you to easily copy templates over from premade projects in the gallery.

    I learned to use it for writing scientific publications, but eventually I used it for all my homework, making ‘official’ looking DnD content, keeping a log of my work; basically most documents that are longer than 1 page. It is particularly good for science and math writing, but is almost as versatile as HTML for whatever you want to make.






  • Sometimes, mainly when it is stuff that isn’t rooted in true or false. If I am factually wrong, it isn’t usually concious and I tend realize my mistake after the fact. If I am in the wrong in an emotional/moral way, I tend to realize my mistake while I am still emotionally charged, so I am not always ready to acknowledge it or effectively communicate my apology, though I still try to either admit fault or tell the other person I’d like to discuss it after I have calmed down.

    Either way, I usually allow some amount of time for self reflection, which I think is better for me. It allows me to formulate my reasoning for apologizing/admitting my mistake, calm down, and let go of the ego. I have found that even if there is a long pause, the other person almost always will take the follow up discussion with kindness and respect, and appreciates the emotional/intellectual honesty and vulnerability. Nobody has ever rubbed it in my face. Which helps encourage the practice going forward.

    It also, in general, facilitates better real-time admission of incorrectness to practice in this way.


  • I have struggled against this for a long time. I tend to be a pretty prideful person and the urge to shift blame when I fuck up and deflect when faced with being wrong is something that has I have to actively work to correct. The difference for me came when I was younger in dealing with my parents: My dad was far from perfect and there were plenty of times he was in the wrong, but always made sure to sit down with me and apologize if he fucked up. My mom, for the most part, was better at avoiding being in the wrong in the first place, but when she was, I never once got her to apologize or admit her mistake. Of the two, I was hurt far more by the latter, and make it a point to be willing to admit my shortcomings.

    The most difficult part after I identified it as an issue is to not let my willingness to apologize/admit my mistake become a carte blanche for continuing the behavior. If I fuck up, apologizing only means something if I work on the mistake. If I am wrong about somethimg, I should learn about both the thing and where my misconceptions came from.

    For a lot of people, realizing it is an issue is difficult, because you first have to let go of the pride by acknowledging it. Shame isn’t a good motivator, as it makes most people double down on pride.

    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.
