Hello new users, or folks coming back for a second try! If you are turned off by the UI, and you don’t mind paying for an app, give @Ivory or one of the other 3rd Parth clients a try. They make a world of difference.
Fact-checking Elon Musk’s incorrect statement about #farming and #climate change: https://factcheck.afp.com/doc.afp.com.33LP6PR
1) #Agriculture, #forestry, and other #landuse account for ~1/4 of recent annual GHG emissions.
2) Factoring in the broader #food system brings the estimate to ~1/3 of emissions.
3) #Deforestation & other land-use change account for >1/4 of CO2 emitted since 1750.
4) Keeping warming below 1.5 degrees C is impossible without changing food production and consumption.
@gmusser - there are currently many things about Mastodon that make it unable to serve as a Twitter substitute. They are well analyzed here:

If I were a journalist I'd be in a bind. As a late-career mathematical physicist I decided to spend less time on social media and more time thinking. It's been a boon!
Welcome to #Mastodon #Twitter and #Reddit lovelies. Enjoy your stay, in time you'll find a healthier place here. Visit www.fedi.tips for a 101 and feel free to ask away if you are having trouble. Pepper your posts with hashtags to be seen. People like to see who you are so post a picture too! People are kind here, it is a place for conversation and connections instead of billboards. Check out @FediFollows for cool accounts. #twitterMigration

@nickbwalking I wonder, did he happen to be in possession of a monkey's paw at the time?
Lest anyone doubt that Twitter was idiotic enough to release code that would cause a race condition and result in its own users executing a DDOS attack on it, here's the network console readout from Firefox showing all the network requests blasting away.
Of course I immediately closed out my connection because I'm a good person. Oh, but it's the weekend and Evil Sheldon is in control so I kept the party going for a while since Twitter insisted on it.
Unbelievable. It's amateur hour.
Welcome to fleeing Twitter ppl ❤️
If you’re looking for stable spots I will note that Bluesky is currently down, presumably as a cascading result of the exodus, and also it’s…pretty weird over there rn due to bizarre moderation choices. I’m not a “Bluesky Is the Devil” person but I wouldn’t recommend it just yet.
Masto has some real problems, but if you get on a good server it still seems like the best lifeboat to me.
I have a friend who’s joked that the movie about Elon Musk’s time running Twitter could never work as a piece of fiction because no one would believe such a successful businessman would have so many bad ideas about running a company.
Every decision being bad would be too unrealistic. Yet here we are.
In some fields of science, such as physics and machine learning, I’m finding that Twitter has gotten only *more* important in the past few months. My principled refusal to use that platform is beginning to hurt me professionally; I’m missing out on important discussions (including about my own articles). I’ve had some great exchanges on Mastodon and value the relationships I’ve forged here, but, as much as it pains me to say this, it’s just not the same. What can we do to fix this?
@johncarlosbaez It's funny because, of course, as a theoretical physicist I took a fair amount of math, including graduate courses in the math department, but not one of them even mentioned the existence of Category Theory. I only ever heard about it from random folks I talked to online.
To me it mostly seemed like a curiosity, a different way to formalize mathematics (rather than the set-based approach I was used to), sort of like using an algebraic axiomatization of probability theory rather than the traditional set-based Kolmagorov approach. Of course, I guess even that leads to interesting things like being able to define non-commutative probability theory, so I probably should have known that Category Theory could lead useful places. Seeing that you seem to consider it so important definitely has made me think I must be missing a really useful tool.
@johncarlosbaez Thanks for this! I enjoy reading your posts, but having never really learned about Category Theory a lot of them end up being pretty opaque to me. This helps explain at least one of the basic concepts. I keep thinking I need to go do some reading about Category Theory so that I can better appreciate the stuff you talk about.
I guess next I need to figure out what a monad is (outside the context of Leibniz's metaphysics). 😁
Congratulations @ec_euclid on the successful launch and separation of the #EuclidSpaceTelescope !!! I think any time something you've worked on (or care deeply about) launches into space, this is when you can't help but breathe a sigh of relief. Good luck with the hard work of spacecraft and instrument checkout! I can't wait to see what #ESAEuclid teaches us about dark matter and dark energy!
#astronomy #Euclid #EuclidMission #EuclidConsortium
For those following the #EuclidMission launch development. It looks like the hashtags #Euclid #EuclidConsortium and #EuclidSpaceTelescope are also in use. It appears that @ec_euclid is the official account for the consortium.
@telescoper You'd have me with smoked or cured fish for breakfast. Sadly, sometimes picked herring is a bit too sweet for my taste.
Theoretical physicist by training (PhD in quantum open systems/quantum information), University lecturer for a bit, and currently paying the bills as an engineer working in optical communication (implementation) and quantum communication (concepts), though still pursuing a little science on the side. I'm interested in physics and math, of course, but I enjoy learning about really any area of science, philosophy, and many other academic areas as well. My biggest other interest is hiking and generally being out in nature.
