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!

  • 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.


  • 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.




  • 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.



  • 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.

    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.

  • 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.
