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.

@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.

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

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 ? 👨🏽‍🔬

@rastinza @erinnacland @academicchatter @alexh Hi there! "I hope they'll add a chemistry journal" -> Peer Community In is managed by scientists. Any scientist can initiate the creation of a PCI in a field not already covered. Please read our blog post "Steps in the creation of a new PCI" and do not hesitate to contact us! https://peercommunityin.org/2019/05/21/steps-in-the-creation-of-a-new-pci/

Hey @rastinza, a platinum/diamond #OpenAccess journal with chemistry focus can be found here: https://www.beilstein-journals.org/
I already published there, and can recommend.

Non-profit journals as a solution to open science?

Publishers charge researchers incredible amounts to remove paywalls from their own papers...and make unbelievable profits from doing so. Several have an >30% profit margin.

Initiatives such as @PeerCommunityIn provide an alternative: open access, non-profit journals that are free to publish in.

Carnivorous oyster mushrooms can kill roundworms with “nerve gas in a lollipop”

https://arstechnica.com/science/2023/01/carnivorous-oyster-mushrooms-can-kill-roundworms-with-nerve-gas-in-a-lollipop/

"The mushrooms have evolved a novel mechanism for paralyzing and killing its nematode prey: a toxin contained within lollipop-like structures called toxocysts that, when emitted, causes widespread cell death in roundworms within minutes. Scientists have now identified the specific volatile organic compound responsible for this effect"

Bisogna rinazionalizzare le ferrrovie, e renderle gratuite, per togliere auto dalla strada.

E le ferrovie devono tornare a fare il servizio pacchi come facevano una volta, per togliere furgoni dei corrieri dalla strada.

E i CEO che piangono li mandiamo a zappar cicoria in Sud Sudan (dove non hanno ancora sminato).

#LightPollution is the dumbest pollution.
