I THINK SOMEBODY JUST FEDERATED MY TOOT

#researchers with a #mastodon account and a known field of work (as known by #wikidata) https://w.wiki/649f

Most represented fields of work:
1 #SemanticWeb
2 #ComputerScience
3 #MachineLearning
Good illustration of the bias in the data ^^

Unsolvable mystery. #comics #ComicStrip #funny

Twitter, Facebag, Insta, TikTok are all social media, which like traditional media are bought and paid for. The Fediverse on the other hand is a social network, a platform for communication.

Along with #dark #energy, dark #matter represents a major embarrassment for #physicists. Together, these two unknowns mean that over 95 per cent 📊 of the #universe is made up of stuff not #categorised 📉 in the #standard model of #particle #physics, our best theoretical picture of #material #reality https://www.newscientist.com/definition/dark-matter

Now Musk is saying if Apple and Google block Twitter on their app stores, presumably for failure to moderate hate speech and for safety, he will just create a new phone.

So it’s going well, right?

This is one of my favorite pictures. It feels like it was taken yesterday… but it was taken in a Paris public garden nearly a hundred years ago. Everything feels modern: the composition, the casualness, the daring clothes, haircuts, and accessories.

The colors are original: this is an #autochrome, using the first process for color #photography invented by the Lumière brothers in 1903.

The women are unknown, but I can't help wondering how they fared a few years later in nazi-occupied Paris.

Math Skills x Stage of Life

(Okay, I do a bit more than spreadsheets, but I still chuckled). Not sure who made this, but it's brilliant 😆

On how old is our universe, and what's its size, the Hubble Constant and a Cosmic dilemma, and how the Universe’s dark-matter dominated structures have formed over the eons of time -- check out the University of Hawai'i News on the publication of the Cosmicflows-4 Catalog: https://hawaii.edu/news/2022/09/26/map-galaxies-largest-ever-catalog

Pentagon biolabs around the world. Some in Ukraine too.

Couldn't help it and did this last night. I'm still in awe at the level of detail in this image! Look at those spiral dust lanes.
