I don’t mean to pick on you in particular here, but this approach has been bothering me a lot lately, and it seems like it’s super common. I get that it’s an early prototype and not all the design choices are made yet, but I struggle with “

I often start prompts with “please”, but I usually don’t thank the model. Framing a question or a request for help with “please” is in distribution for me, it’s a distraction from composing a thoughtful prompt about my actual question to go

True. But it has no idea that it has no idea, so it might be able to look back at the session trace and pattern match its way to actionable feedback?

I think JEPA is super interesting, but I feel like this example highlights some of the challenges of long horizon planning. For one, chunking the planning stage into a bunch of intermediate goals seems really limiting, because a lot of what

What aspect do you consider basic? I haven’t had a chance to read more than the abstract because of the paywall, but the really interesting thing here is the mechanically induced transformation that leads to a 3-phase nanocrystalline alloy.

The science daily article is just incorrect to call this a superalloy, which it is not. This is a high entropy refractory alloy (HfNbTaTiZr), superalloys are usually based on lighter metals and they usually have only one dominant element w

This is really cool metallurgy. They start with an alloy and deform it and because of elemental size mismatch they can cause the alloy to self assemble into nanoscale crystals with three different structures The paper: https://ww

Terry Tao has actually been one of the more prominent voices in the math community exploring AI for cutting edge mathematical discovery. This particular post is a bit softer but he has also written a lot about using AI assistance for seriou

But this is true for lots of solids, not just glass. Consider creep deformation [0] which is deformation mediated by diffusion of defects in solid materials. It’s a big problem in metal turbine blades, it limits the maximum usable temperatu

Maybe I have too optimistic a mindset, but “just be honest” in academia isn’t about being a rule-follower, it’s about not short-changing yourself by coasting though on autopilot instead of learning to think and solve problems for yourself.

In my experience the input field lags on short chats too, sometimes in the middle of writing the second or third prompt. Are they running some kind of prospective evaluation or something?

If the explicit role-playing prompt is just to identify multi-valent terms, then revising the question to include more specific context without a role-play prompt should work just as well right? I’d be really interested if anyone has evalua

That’s the active research area GP mentioned. In startup land there are a few large outfits, Lila Sciences, Period Labs, Radical AI are all doing a mix of simulations, AI, and autonomous laboratory infrastructure specifically for materials

It depends what you mean by commercially interesting. There’s loads of interest in aerospace (for high temp corrosion resistant structural components) and catalysis but these alloys are pretty much across the board at a relatively low level

It seems like an opportunity for a hierarchical cache. Instead of just nuking all context on eviction, couldn’t there be an L2 cache with a longer eviction time so task switching for an hour doesn’t require a full session replay?

I think the exceptionalism is the other way around. What makes anyone think they understand what makes for intelligence when we barely understand our own neurology?

It is, but NSA reports to the director of national intelligence, not the defense secretary, so it’s unclear (to me at least) that SecDef’s opinion of Anthropic counts for anything here I guess DOD is large enough they have multiple parallel

Admittedly my understanding of QM is a bit vibey but I’ll try to answer In an atom, angular wavefunctions with wavelengths non-integer divisions of 2pi can’t exist because of the boundary conditions on the wave equation. A free electron can

by rsfern 6mo ago
The reason is that electrons (like all quantum mechanical objects) are wavelike. In an isolated hydrogen atom, the electron is in a spherically symmetric environment, so the solutions to the wave equation have to be spherical standing waves

While the treatment for methanol poisoning indeed includes ethanol, I don’t think your dosage suggestion is right. Your body would still have to process all the methanol, the job of the ethanol is just to slow down the reaction. If you susp

I like this analogy of always choosing “I’m feeling lucky” on Google, I feel like it clarifies a boundary between information retrieval and evaluation that gets blurred by language model summarizations. I’ve been frustrated with the LLM sum
