I'd say it is quite useful to quickly get a birds eye view of a topic.
Do you trust anything written in there? Obviously not, but you can find a lot of useful keywords related to a topic you know nothing about and save yourself quite some time.

Periodic reminder that I've written a free tiny book on quantum chemistry which teaches you how to compute electronic orbitals of hydrogen atoms (and more!) with just some Python knowledge! It includes the resulting code and explains it step by step.

"That is why Nature is setting out these principles: ultimately, research must have transparency in methods, and integrity and truth from authors. This is, after all, the foundation that science relies on to advance" 👏👏

@hasmis I frankly didn't understand what you meant. I have noticed American people often don't realize the world is vast and that many people are not adept to the social and political mechanisms that are normal over there. I have asked you to explain what you said, I don't see why you should insult me by implying I'm locked in my ideology and I'm not willing to listen to different opinions.
Now, I'm interested in this lawyer cartel. Would you explain what you mean?

I didn't know about all this thing, never seen anything about it on local newspapers.
Johnson and Johnson had been sued by several people because apparently some of the baby powder it sold contained asbestos, which led to several young people developing cancer.
Recently, the company opened a spin off and gave it ownership of that product, and with it the legal liability. That company filed bankruptcy, thus victims will not be compensated.

Quite disgusting story. Shame on the USA governments allowing companies to behave in such a way.
I found out the company is in one market index I own; I'm considering selling that and getting something else.

@Mcx83 @donatacolumbro I can clearly see that China is the big problem here.

@rastinza - the SiO₄ tetrahedra in quartz are less densely packed than the tetrahedra I showed in part (1/n). I imagine that any packings of tetrahedra in nature that have already been seen are no denser than that one.

@johncarlosbaez It is a highly interconnected network, this makes is much less dense than what it could be.
I have not worked in this field, but I do imagine there are materials which are much more packed than this.
I imagine nobody ever observed packings denser than that, but there may be different types of packing available or some materials might be designed specifically to increase the packing.

@johncarlosbaez Oh, damn. Could this packing problem be improved by experimental findings? I know we discuss packing a lot in chemistry, but that's mostly from the observation of crystal structures. And generally they use spherical models for the atoms. I know nothing about it, but I guess someone might be studying the packing of some compound forming tetrahedras like quartz, maybe a little bit less interconnected.

@johncarlosbaez Wow, extremely cool! Though I'll give it to Aristotle, with the things he might have had to pack, such a density does equate complete packing.

@rastinza see, that's what my post would have been LAST WEEK!

@xtaldave How did they even come up with the idea? Next time I'll add vim among the authors, after all its contribution was fundamental in the writing process and we could argue he even did 100% of it.

@aljazeera Nice article, but I would not equate companies exploiting their workers and the internet being more and more controlled by commercial companies.
These are not the same thing, in some cases there is a correlation between the two but this doesn't mean they're the same thing.
Moreover, it feels a bit of a stretch to imply that chatgpt is being developed with the objective to commercially dominate the internet; especially when it is being developed by a non profit organization.

@hackernews@die-partei.social How this guy ruined the economy and made hundreds of people lose their job. I guess that's what they'd say if he was to come up with such an idea after they already started producing the more expensive alternative.

Today felt very productive:

1) Got a response back on a paper that we could immediately address and correct, so I did. Here's hoping it's over 🤞

2) Got a grant back down to the word limit (started the day at 1.2x the allowed length!) 📝

3) Saw some cute fruit flies under a microscope 🔬

4) Wrote this Toot 🐘

That's basically #science right #ScienceMastodon ? 👨🏽‍🔬

@MarkHanson Today I felt very productive:
1) Got an email I should have received months ago, didn't reply.
2) Got a grant up to 5x the word limit (started at 0.8x the allowed length)
3) Stayed overtime to work on some stuff unrelated to my job, but in the office I focus more.
4) Met some colleagues I didn't know.

I'm pretty sure this is basically
