#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 (and facebook's tanking stock!) made me create an account here.

As a complete n00b, 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.

@arkayar @mona@cybre.space

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.
