After weeks of clear skies it looks like we’re having eclipse weather in SB

1/11 #JWST has revealed something unprecedented about Neptune. For the first time we have spectra of three small inner moons (Larissa, Galatea, Proteus) and the rings. 🔭 Their composition is unique in the outer Solar System.⚛️🧪 www.caltech.edu/about/news/n... #planetsci #Astronomy #Science

$Diagram showing the proposed origin of Neptune’s present-day small inner moons and rings. An earlier system of large moons is shattered when Triton, a captured Kuiper Belt object, arrives. The breakup exposes clay minerals from the deep interiors of those ancient bodies; a small fraction of the resulting debris later reaccretes into the moons and rings we see today. Credit: R. Davis$

Gottfried Wilhelm Leibniz was born #OTD in 1646. He was one of the great polymaths of the age, and is best known for discovering differential and integral calculus independently of Isaac Newton. 🧪 🧮 Image: Wellcome Collection

I feel like we’re willing to make Pluto a planet again, at least provisionally, if they’re willing to fund astrophysics. I’d say $100 billion/year is reasonable But if you keep cutting our budgets, I swear we’ll keep eliminating them. Hope you like a three planet solar system!

Thought for the day: Earth is 10^30 times as dense as an averaged-out sample of the universe. That is, gravity has amplified the density of our planet by a factor of thousand billion billion billion. Without that amplification, we would not be here. 🧪🔭

This illustration summarises the almost 14-billion-year long history of our Universe. It shows the main events that occurred between the initial phase of the cosmos, where its properties were almost uniform and punctuated only by tiny fluctuations, to the rich variety of cosmic structure that we observe today: stars and galaxies.

The series of panels on the right side of the illustration zooms into the cosmic large-scale structure to reveal first a cluster of galaxies, then a spiral galaxy similar to our own Milky Way Galaxy, and finally, the Solar System.

After 6 years of swimming in a 20 m pool 50 meters feels like a long way to go.

Looking down the length of a 50 m outdoor pool.

As a physics teacher, this is the part of student AI use that worries me. (Not all of us have decided that things are different this time.) 🎢 🍎 Ref: ergosphere.blog/posts/the-ma...

The strange thing is that we already know this. We have always known this. Every physics textbook ever written comes with exercises at the end of each chapter, and every physics professor who has ever stood in front of a lecture hall has said the same thing: you cannot learn physics by watching someone else do it. You have to pick up the pencil. You have to attempt the problem. You have to get it wrong, sit with the wrongness, and figure out where your reasoning broke. Reading the solution manual and nodding along feels like understanding. It is not understanding. Every student who has tried to coast through a problem set by reading the solutions and then bombed the exam knows this in their bones. We have centuries of accumulated pedagogical wisdom telling us that the attempt, including the failed attempt, is where the learning lives. And yet, somehow, when it comes to Al agents, we've collectively decided that maybe this time it's different. That maybe nodding at Claude's output is a substitute for doing the calculation yourself. It isn't. We knew that before LLMs existed. We seem to have forgotten it the moment they became convenient.

Centuries of pedagogy, defeated by a chat window.

Unfortunately I am getting to the point where if I see an especially cool astronomy or other nature photo my first reaction is to wonder if it’s AI generated. The fact that some clearly are fake doesn’t help.

Would you like a little red light with your moon?

I’m new here, but I can see the similarities to an old social media platform that will remain nameless. I’m sorry I’m on the wrong side of the planet for today’s eclipse.
