It should be noted, of course, that companies that sell LLM services aren't, in fact, making knowledge freely available.

I'm just not sure it's cut and dry that LLMs are particularly unique in this regard.
In science, there is a tension between the free use and availability of knowledge, and credit or even lockdown of intellectual property. In creative arts, from what I've seen, things lean toward emphasizing the latter, even though a strong argument can be made...

It really was weird. I'm guessing it's why lawyers, and even some judges, have gotten themselves into serious trouble using LLMs to write briefs. The LLM invents non-existent case law, and even confidently cites it.
(though it kept inventing non-existent libraries I had to then code around)
I have thus far gotten good answers in both writing Arduino code (though it kept inventing non-existent libraries I had to then code around) and spectral line fitting in astronomical data reduction (with some fixes).

I've also seen good performance in digging up references to relevant papers.

I recently took part in a discussion of the use of LLMs. I have to admit, I was taken aback by the hostility from some quarters toward any use of LLMs, which even extended to ad hominem reactions.

I suspect a lot of it revolves around creative/IP issues.

We are pleased to announce our discovery of #GW241011 and #GW241110

Both come from binary black holes where one black hole is much larger than the other. The larger black holes have large spin. Could these black holes have formed in a previous merger?

Science marches on, and interestingly, one strain of science denial centers around the idea that black holes haven't been shown to exist. We're actually well past that point, with multiple lines of evidence stretching back decades.

This is a cool find.

Where are we located relative to the Big Bang?

#AskEthan

The Big Bang didn't occur at a single location in space, but rather, everywhere at once.

If we assumed it was a big ka-boom, we'd be shockingly close to its origin point.

Ask Ethan: Where are we located relative to the Big Bang?
If you think of the Big Bang as an explosion, we can trace it back to a single point-of-origin. But what if it happened everywhere at once?

I missed everyone talking about the 100th anniversary of Cecilia Payne-Gaposchkin’s dissertation yesterday.

BUT, just four short months ago I wrote a whole thread about her and work, so idk maybe I was early?

Just a note of further recognition regarding the Deep ocean Assessment and Reporting of Tsunamis (DART) buoy system.

Incredible technology, sensing anomalous changes in ocean depth using pressure sensors from sometimes thousands of meters below the surface.

These things save lives.

Happy birthday, Vera Rubin! 🥳✨

What better way to celebrate than with NSF–DOE Rubin Observatory's view of galaxies SHE studied?

Busting the top 5 myths about the Big Bang

There are lots of arguments against the Big Bang, and many proclamations that it's already been disproven.

But those are mostly based on an incorrect depiction of what the Big Bang even is.

NSF is the U.S. National Science Foundation. NSF has existed since it was created by statute in the 1950's, and employs what is widely considered the "gold standard" process for science funding.

NSF covers many scientific disciplines, and disburses nearly all of its $9B annual budget in grants.
