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.

5·2 years agoAnother 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.

8·2 years agoApply 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…

Ask Lemmy@lemmy.world•If you got COVID and lost the ability to taste things, did it ever come back? Otherwise, did you experience any other long term consequences from the pandemic in general?
5·2 years agoTotally 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!

Games@sh.itjust.works•The ESA Has Announced That E3 Is Officially Dead
66·2 years agoI 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.

RPGMemes @ttrpg.network•Out of the last 20 scheduled games, we've played 11
5·2 years agoThere have been hiccups, and we aren’t always at 100% attendance, but I am really proud of my group for making the time to play (almost) every other sunday at a set time. On the weeks we miss, they are also good about adjusting their schedules so that we do a back-to-back weekend instead to make up for lost time.

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.
