Here goes:

During my dissertation, I was lookig for information on the emissiom of 172nm scintillation light in mixtures of gaseous Xe and CO2 (95:5% - 98:2%), with results being difficult to come by. I found a collaborator who had tested this at lower CO2 concentrations (0-0.5%), but nothing else, no predictions or generalizable applications. Not knowing the optimal search engine terms or what textbook to look in for rules governing gaseous light emission, I ended up looking in fluorescence chemistry papers (my previous field of study) which had something called the Stern-Volmer relation for different concentrations of quenchant in a fluorescent solution. I figured gas scintillation queching was probably similar to liquid fluorescence quenching, but the standard relation didn't quite fit below 10% additive.

I dug around more and found a modification of this relation for diffusion-limited quenching of fluorescent solutions (the same limitation imposed in gas mixtures, quenching due to random Brownian collisions) that employed an exponential term, allowing for a smoother curve down to low additive concentrations. This perfectly matched the available data and allowed me to model the predicted behavior. I discussed this with the one member of my committee who was available, an organic chemist (my PI was on vacation, everyone else was sick, and my dissertation defense was in 2 weeks). He said my reasoning and math for using this formula made sense and gave me a thumbs up to include this analysis. When my PI came back from holiday, he asked me why I didn't use some equation generally used in the field, or even just a generic exponential fit. I was ignorant of his suggestion, but it provided the same general formulation as Stern-Volmer, though Stern-Volmer was more rigorously derived mathematically.

Mixing fields is super cool and can allow a much deeper understanding of the underlying principles, as opposed to limiting yourself to one branch of science. While my PI's recommendation would have given approximately the same answer, understanding and applying Stern-Volmer allowed me to really dig at the principles at play and generate a more accurate and in-depth model, which I managed to write up and defend at the 11th hour.

I am half way done with mine, which means I only have 3/4 left to write, then I will be 90% done.

I am a physicist. I am good at math, okay at programming, and not the best at using programming to accomplish the math. Using AI to help turn the math in my brain into functional code is a godsend in terms of speed, as it will usually save me a ton of time even if the code it returns isn't 100% correct on the first attempt. I can usually take it the rest of the way after the basis is created. It is also great when used to check spelling/punctuation/grammar (so using it like the glorified spellcheck it is) and formatting markup languages like LaTeX.

I just wish everyone would use it to make their lives easier, not make other people's lives harder, which seems to be the way it is heading.

I have both ADHD and minor hearing loss that started when I was a teenager (wear earplugs if you frequent concerts and play in live bands, turn the music down on your headphones from max volume). It is a rough combo that led to plenty of awkward situations as an awkward teen.

The worst was when I was on a first date at a SixFlags and my date didn't tell me she was terrified of rollercoasters. I felt bad, but only went on a few rides without her and spent the remaining time trying to win a stuffy at a carnival game for her, trying to have a good time anyway. She was really really quiet and I was having a hard time with all the stimulus and crowd noise understanding her. Eventually, it got to the point where I was asking her to repeat everything more than once, so I started to autopilot. While we were waiting in line for something, she muttered something and I responded, my brain playing fill in the blanks, "Uh-huh."

Turns out, when I heard her say "Mumble mumble ride mumble bring mumble with you mumble." she was not saying, "I really wish I could go on a ride, but I am happy you wanted to bring me with you anyway!"

She was, instead, saying something along the lines of, "It must be so annoying that I haven't gone on a single ride, I bet you regret bringing me here with you at all today."

Needless to say, there was no 2nd date. She told me later it was shitty of me to respond like that, and I couldn't convince her that I just misheard her. Since then, if I can't understand someone after two tries, I just explain that I have bad hearing and need them to speak up. Asking someone to repeat themselves will always be less awkward than driving her home after that.

I avoided shorts on YT religiously, but as people sent them to me and they became more tuned to my preferences, I began absent mindedly scrolling them. I fucking hated it, I would realize I had wasted so much time idly swiping. I started running revanced specifically to turn that shit off on my phone so that the temptation wouldn't exist. So happy with my decision. I don't think it rotted my brain, but it made my phone a landmine for shit content, scammy ads, and wasted time.

Physics is a mixed bag with this stuff. Gell-Mann came up with the name quarks after a line from Finnegan's Wake because Joyce referenced them as coming in three. It was a nonsense word inserted just to rhyme with Mark, Park, etc, so its pronunciation in physics isn't even correct, but it was fun and physicists were just having a good time with it.

Three quarks for Muster Mark! Sure he has not got much of a bark And sure any he has it’s all beside the mark.

Then we got the strange/charm and top/bottom (which was originally the beauty/truth, so bullet dodged there) so the quarks really got all the fun names. Strong Force physics in general gets the good stuff: Axions were named after a detergent because they helped "clean up" the strong CP-violation problem of the standard model. Fantastic, no notes.

Neutrinos (my field of study), had so much potential for fun, stupid naming that was squandered. The neutrino was originally proposed with the name "neutron" by Pauli, but then the actual neutron was discovered and observed first, so the name got pinched. To remedy this, the electron neutrino was dubbed "neutrino" or little neutron (they didn't know that other flavors of neutrino existed). Meanwhile, the muon neutrino was originally supposed to be the neutretto (before they realized that the neutral leptons were related by the different particle generations), so we could have had a world where each generation of neutral lepton was just another combination of neutron + diminutive italian suffix.

  1. Neutrino
  2. Neutretto/neutronetto
  3. Neutrello/neutronello

Then, when the mass eigenstates were confirmed, we could have diversified and gone with big suffixes to indicate that neutrinos have mass.

  1. Neutroni
  2. Neutrachione/neutronachione
  3. Neutrozzo/neutronozzo

But noooooo, particle physics decided to just give neutrinos the lamest possible names, electron/muon/tau neutrinos for flavor states and m_1/m_2/m_3 neutrino for mass states. I am ashamed of my predecessors for what they've done.

Don't even get me started on the J/Psi debacle...

In my first year of grad school, I was visiting a colleague's lab and was asked if I wanted to test some of their new diffractive optics. I said sure and started toying with the big lens on the table, no gloves, no precautions other than trying not to drop/smudge it. After about 5 minutes of geeking out over the fact that a perfectly flat, transparent lens was focusing the light, I asked how much it would cost to get one sent to my lab for an experiment I was working on. He said that it was the only one of its kind in existence, but the manufacturing r&d cost for it was over $50K alone. My heart nearly fell outta my chest.

I pitched this exact idea to my fiancé a few days ago (and have no clue why it came up). she didn't think it was a good idea, but now I can tell her that it was good enough to patent.

My mom had an inspirational sign in one of her bathrooms that said, "Embrace this moment, for this moment is your life." perfectly matched to her decor. She knew exactly what she was doing.

To be fair to the post, it is describing how to tell people who wear all black apart, not categorizing them goth subtypes. Punk is also not goth.

Would love to split my time between physics research and hobby botany/native plant restoration efforts. Would happily do both for free if I could. Damn capitalism

My goal for the summer was to finish my PhD. I defended on Friday and am now Dr. Drail, so I actually accomplished my summer task for once. I sacrificed all my sleep and sanity to do so, as I was told at the 11th hour to redo a major analysis that made up 1/4 of my dissertation, but I fucking got it done.

The assignment was to infodump, so I will take that as a compliment. I was aiming for detailed and hyperspecific.

Twice, both related to my Crohn's Disease.

The first was in preparation for my first colonoscopy, where I was told that I was only allowed clear broth, clear soda, coffee, and water for 24hr before taking the colon prep solution. I didn't think the diet would give a mile-long headstart before the prep solution, so I enjoyed copius amounts of clear broth and coffee, which ran through me like a river, resulting in the mishap. The bathroom was only 10ft away from me, but it was still too far given the rapid pressure buildup.

The second was during an insurance conflict about my Crohn's Medication, resulting in a flareup and multiple weeks of gut agony and loose stool. It got to the point where no flatulence was trustworthy, and I took a gamble because I was so tired of getting up to run to the restroom every time I felt something bubbling (10+ restroom visits a day, each at the slightest sign of stomach rumbling will do that to a motherfucker).

It is always humiliating, even when I am home alone, and I am hyper concious about the possibility, even when in remission. It fucking bites.

It seems like a great way to send ~50% of the babies birthed out in space. Just remove the net, speed it up, and tilt it 90°, then you have a coin flip chance at space babies or crater babies.

If one is in your area, Winco is your friend then. 24hr grocery shopping. They are also worker owned and have a great bulk goods selection, so they are a better food shopping experience at roughly the same price point.
