I think I missed most of the Lamat awardees! I'll have to read the list more closely

last year I co-led a project where we built a solar telescope and to make sure we got the size right without risking our eyes we tested it on the moon! (Green from an iron-line filter)

i think i just read this as well and, yeah that didn't sit well in multiple ways. A bunch of motivated reasoning

astronomy is so funny because it's this fairly niche interest for a small community of nerds and also it's 99.9999% of everything that exists

Human-Style Sudoku Solving I like solving Sudokus, but I’m not that great at them - my strategy mostly involves the following steps:

i once wrote a solver that only used human-parseable steps, but on some puzzles it just got stuck and I wrapped it in a recursive call of "guess, does this lead to a solution, if not make the other guess". That seemed to always work with depth=3 but also idk if I just missed some human strategies

Ooh can you post these? I read latex easier than a thread

i think this is basically always the case in astronomy research

have revised this take: i think i was underrating how much intuition building happens as part of the process of writing science code. Claude can get to many subproblem answers faster than I can but I end up feeling hollow - missing a sense of satisfaction I didn't know I had till it was gone

Also without models that are more local/without the huge environmental footprint/without being locked to the big ai companies. I hope we see democratization of LLMs so we can make narrowly scoped tools that actually work/have guardrails and the hype can end

I think the aspiration of pro AI people is to push up the abstraction barrier so you don't have to know code specifics, in the way that many scientists now don't need to know low level computer architecture unlike a few decades prior. But you can't get there without reproducibility

Yep fully agree; I was imagining this at the grad student+ level. I think earlier on you'll be totally lost if you don't hand write it all yourself

The Impending Rise of Vibe Science LLM-based programming is tempting for science because people mostly want to spend their time thinking about the problem they’re interested in, rather than writing code. This isn’t helped by the narrat...

I also think you will learn a lot by writing some things by hand, but I could imagine that doesn't always apply. But for research integrity I think you do always have to do your vetting by hand no matter how you got the code

ok I have a take here: i don't inherently mind ai generated code if it moves the person's focus to writing tests/sanity checking, because that should be happening for human written code too and is arguably where the physics is. But you do have to actually do the checks, and lots of ai users don't

I have literally said things like this to my friends and I go on walks so I can completely understand things!

Our prospective students are flying out here today, I think the Northeast ones are just barely going to make it but who knows

As a grad student who's recently taught a class for first-year grads I really like the section on focusing on learning over just producing work! I think a grad costs ~as much as a postdoc, and is bound to produce less, but it's worth it for our learning - it's nice to see the field-wide view of that

I just got done with spirit of lyot and the number of times I saw either this or the hr8799 video, people were apologizing for still doing it by the end

I like reading blog posts or latex docs more personally! But would ultimately read whatever format

The most charitable read I've got is "we had opportunities/advantages you didn't, so you should go easier on yourself" but even then it's really poorly expressed

The title and author list of the linked paper, "On-sky Demonstration of Second-stage Wave-front Control with a Photonic Lantern"

The title and author list of the linked paper, "On-sky Demonstration of Second-stage Wave-front Control with a Photonic Lantern"

My paper demonstrating second-stage wavefront control using a photonic lantern at the Shane 3m telescope at Lick Observatory has been published in the Astronomical Journal! Good start to the year!

The more these scenarios come up the more I realize my position is incoherent - i know there must be a concrete opinion that broadly agrees with my gut sense of "I don't trust it but maybe that's okay for some stuff" and captures all the nuances and fully guides how we should teach and learn and invent stuff, but I'm not there yet

Omg literally something I said the other day thinking about how to teach/do research now. I've felt so bad that I can't resolve these conflicts so this helps

as someone who may not be a researcher if not for prof layton this is so sad
but also, not clear to me if this is more like "we should let ai write the layton puzzles" or "we should write the game in cursor instead of vscode" - even when specified to genai we seem to have terminology issues
