And they walked passed eachother and said nothing... The end 😅

Are you more of a leave early or arrive late kinda person?

An equal superposition of a 1 s and a 2 pz orbital.

The color represents the complex phase of the superposition viewed from the rotating frame in which the phase of the 1 s is frozen.

A couple very rough estimates retrieved quickly in 5 minutes from official Elsevier data.
RELX, the company which owns Elsevier has a capitalization of 56£ billion. Elsevier publishes around 600.000 articles per year and the average price per submission is 2350£ (simple average over submission price in every journal, not counting amount of articles published.)
The average subscription price for each journal is 3524£, I'll assume 600.000 subscription just to have a number.
This means that research institutes and universities overall would pay around 3.5£ billion to Elsevier every year. By saving that money, we could collectively buy Elsevier in less than 10 years.
Maybe we should set up an association, every time you pay money to Elsevier you'd have to make a donation to such association with the objective of buying the majority of RELX.
This would be an economically sound decision.

Exciting to see a new protein generative diffusion model in preprint! We look forward to trying the Genie model from Mohammed AlQuraishi aqlab.io/ arxiv.org/abs/2301.12485 #ai #proteinengineering #proteinai #drugdiscovery

I found this service: fetchrss.com
They are able to convert a facebook page in a rss feed and 5 of these feeds are for free.

My internet connection has been extremely slow for months: when connecting to certain websites I'd have to wait several minutes to load the page. However, the connection is very quick when I transfer data.
Recently, I decided to investigate. Apparently my company is dropping connection to a vast amount of domains; this wouldn't be a problem, if they didn't include a lot of CDN among those domains.
I asked the IT technician, who said that the security system mistakes CDNs for spam addresses.
Now people, host your own style sheets please, as I otherwise have to wait several minutes to get bootstrap, which you use for setting a header and nothing more.

I'm amazed by the fact that hundreds of people work here and nobody ever complained about it...

Fuck CDN, Fuck people dropping packets rather than rejecting them.

How to get a Facebook page as an RSS feed? Here they have very cool sociocultural centers that publish the activities on Facebook, and I don't want to regularly log on Facebook just to check events.

Yep, for those who won we don't actually know how long they may have survived. Each season there is only 1 winner (except S4). The winners would need to survive ~2.3x longer than they did to balance the average days lasted for men and women. With that in mind I think this is a fair metric to compare genders more generally.

Ho smesso di fumare, non per la salute o robe del genere.
Dopo anni di onesto scrocco professionale ho dovuto cominciare a comprare tabacco perché il mio coinquilino fumatore si lamentava che gliene scroccavo troppe.
Però allora non ci stò, non voglio mica comprarlo il tabacco, poi così non c'è gusto.
Almeno prima quando avevo voglia di fumare andavo a farmi un giro e mi facevo una chiacchierata con qualcuno, ora ero arrivato al punto di fumare tutti i giorni in casa da solo.

Sto avendo una fervente discussione epistolare con Massimo Fini ed ho provato ad utilizzare per rimettermi le frasi un po' a posto.
Mi ha sparato fuori questa perla "Meglio non riportare i dati in modo errato, piuttosto che riportarli del tutto."

@rastinza @aspuru @KellyKellyKelly@masto.ai

is even more useful when asking stuff that you know very well and that can't fool you. By knowing it you can quickly read a lot of answers and most of the time there are relevant details you never heard of or connections you didn't make.

I'm currently experimenting with a plugin for that can be used to generate more content alongside my notes to keep it in context and eventually reworked manually; here there is an example (in Italian) with machine generated sentences highlighted:

@rastinza @KellyKellyKelly wow that is incredible ! Do you have a screenshot ? I didn’t know that #ChatGPT knew my group and it’s work :)

I mean, 5 minutes ago I didn't know what an MTT assay was. It was what I had in mind and what I was more or less searching for, but had no specific idea of how it worked and what it was.
Now I know what it is and I know where to find specific information about the methodology if I need to.
And I even had the time to write this post...

Normally, I'd have to find a review about these methodologies and skim through it to find the one I was interested in.

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" 👏👏

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.

@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.
