Fact of the day:
On Mars, sunsets are blue.

Is anyone else here learning how to paint with #BobRoss? I've watched about 50 Joy of Paintings, and I've done three (bad) paintings of my own.

I'm slowly getting better at some things, but I'm still mostly incompetent, and I'm wondering if anyone else is learning, and has experiences or tips to share that have helped your learning curve?

Zeppelin is getting me through the day.

#introduction I am a mathematician and cognitive scientist by training and troublemaker by inclination. I have been following the mastodon universe from the sidelines for a while now but a recent article made me create an account at one mastodon site which led to the next one and the next one and since then I have been following a trail of interesting sites and people.

As a complete n00b here, I am at your mercy. Tell me what I should know and who I should follow!

Timeline synchronicity always makes me so happy.

This is pretty nifty! Mercury vortex in a magnetic field. #Physics #MagneticFields #Electromagnetism

I'm surely forgetting many more, but I'd also say, if you are looking for cool science leaning persons, @InvaderXan @spinflip , @freemo , @pwgallagher, @imvectech, @dereklh

As instances, I enjoy and respect a lot the people from sunbeam.city, mastodon.art, qoto.org, social.coop and refactorcamp.org, between others.

I've never seen something quite as random as the Federated timeline. It's like doing a line of pure internet.

Rocks!

Some of my own work photographing and documenting the Orion Nebula. Old but a favorite. #Astronomy #astrophotography

@codepuppy CO2 is absurdly stable, which is why it's a combustion product and why Venus is full of it.

Each C=O bond in a CO2 molecule has a bond enthalpy of 804.4 kJ/mol. That works out to 8.342 eV so photodissociation would need a photon with λ > 148.63 nm. That's scary far UV.

A krypton excimer laser (146 nm) could break it, but a good catalyst would be far more efficient. :)

@n What you mean is UUCP mail, where you would specify the entire route your messages should take with these hostA!hostB!hostC!hostD

@elomatreb @n In UUCP, the "address" was really a complete delivery path from the sender to the recipient, not really an address. Think of it as a set of turns to make on a road to get somewhere, instead of a destination. And the roads changed out from under you every few days, completely invalidating the instructions on how to get to the destination system to deliver the mail. Fun times, indeed.
