*PRO NERD TIP*

Today I learned about "The Wikipedia Library Card". If you've been a WP editor for >6 months, have made >500 edits, at least 10 edits in the last month, and are not blocked for being a jerk, you can access a *ton* of paywalled content for free.

ScienceDirect, AAAS, The BMJ, both APAs, EBSCO, Springer, Nature, Wiley, and many more.

All those hours in 2005 spent editing sci-fi book articles finally paying off!

🚨 BIG EXOPLANET NEWS! 🚨

Our team has released FIVE papers today on the most COMPREHENSIVE study of an #exoplanet atmosphere to date!

Using #JWST we obtained four transit observations of #WASP39b early in the telescope's operations to study both the planet itself, and the telescope's capabilities to observe exoplanet atmospheres.

We detected numerous molecules in the planet's atmosphere, including CO2, CO, H2O, and SO2 🧵

The future is here! ⭐ 🪐 🔭 #Astrodon #Science

I came across this nice integerological fact:

Define \(\operatorname{ord}_p(n)\) to be the power of \(p\) in the prime factorisation of \(n\).

Then

\[ \sum_{k=1}^n\gcd(n,k) = \prod_{p|n} \left(1+\left(1-\frac{1}{p}\right) \cdot \operatorname{ord}_p(n)\right) \]

I don't know why you'd want to do this, and all the references I've found to it talk about it as a special case of some more general identities, but for some reason it appealed to me.

I'm a graduate student in physics. My recent effort is on understanding the solutions of \(\partial_t^2 \psi - \nabla^2\psi + \psi(\psi\psi^* - \psi_0(t)\psi_0^*(t))=0\). But of course I'm open to be distracted by other good maths. #introduction

My favorite thing about Mastodon so far is that all of a sudden I have posts about history, archaeology, astrophysics etc in my timeline because even though I follow mostly the same people here as tweeter everyone branched out once they got here and started boosting cool people they ran into here.

First batch of Home Assistant Skyconnect is almost ready to be shipped 😀

RT @GeoPythonConf
We're happy to announce GeoPython 2023, March 06-08 in Basel, Switzerland - the conference for #Python and #Geo

hey #datascience #machinelearning peeps! could you please recommend a Mastodon instance for a new tooter interested in ML and data science?

Asking for a friend! thanks!

Possibly the most frightening talent of the brown bear is an uncanny ability to blend seamlessly into the environment in an almost chameleon-like manner, allowing them to easily surprise their unsuspecting prey.

In case people haven't seen this yet, there's an "Academics on Mastodon" list on GitHub here: https://nathanlesage.github.io/academics-on-mastodon/

I'm now aware of 4 tools that can help you find people on Mastodon, particularly people you followed on Twitter. Are there any others?
• Social Search: https://search.noc.social
• Twitodon: https://twitodon.com
• Debirdify: https://pruvisto.org/debirdify/
• Fedifinder: http://fedifinder.glitch.me

In Episode 3, we talked to Dr Lídia del Rio (@azul) about #QuantumInformation and what it took to co-found the community-driven scientific journal "Quantum".

Take a listen to the episode if you'd like to know more!

In Episode 2, we talked to Dr Philippe Faist (@phfaist) about #errorcorrection and #complexity.

How can we make the most of noisy, current-generation quantum computers, and just what is the Error Correction Zoo? Take a listen to find out!

It's a shame that so many people are joining mastodon[.]social and having a bad experience. Unless you enjoy consuming the internet from a fire hose, you're gonna have a bad time. Moderation there is likely not going to align with your needs.
I am fortunate to have been following @nova on Twitter and saw her posting about #hachyderm, such that I was able to migrate to hachyderm.io after only 12 days of joining the fediverse. Even though it's grown to >20k users, the local feed is still readable!

Trying this Mastodon thing by promoting a new preprint from the group on qubit cloaking. Check it out and let me know how it works for you in the lab! https://arxiv.org/abs/2211.05758
