Happy to announce that a ~complete draft of the first three parts is now available at galaxiesbook.org Check it out and please let me know of 𝘢𝘯𝘺 issues/typos/... no matter how small!
Jo Bovy@jobovy

I'm writing a book!! A graduate textbook on the Dynamics and Astrophysics of Galaxies with @PrincetonUPress. But it will be different from what you're used to: the print copy will be accompanied by an HTML version with interactive examples and live code in the browser, 100% free.

That feeling when the print version of your favorite online book/resource on galaxies shouts you out 😭 Congrats to @jobovy for achieving this milestone and a major thank you for providing an incredible resource he’s created! If anyone is ever curious what studying galaxies for professional astrophysicists really looks like, look no further than: galaxiesbook.org

Can anyone tell me the approximate angle between the line joining the central black hole of the Milky way with Sol, and the line joining that black hole with the large Magellanic cloud? Or direct me to a web site where one can calculate this?

Really stoked about this paper with Henry Leung! We develop a versatile neural-network model for 🌟stars🌟 that can tackle many tasks with flexible inputs: arxiv.org/abs/2308.10944 A small step towards an astro-'foundation model': a single model for all of data-driven astronomy!

Why did I feel the need to thank an AI chat bot for helping me with an Excel formula?!?? I mean, it did help me do something that would have otherwise taken me a long time to figure out, but still...

Hey folks! There’s a website (or websites) out there that let you play around in a terminal on the web — any leads? Asking to help a student with a windows computer get some hands on with the things they’re learning

@jobovy Hi, Jo I found a mistake in equation (13.70). The second equality and third equality are overlapped.

@jobovy @github Here's ChatGPT solving a Quantum I homework, with a LaTeX writeup to boot: ocw.mit.edu/courses/8-04-q… - assignment 1, problem 4. It gets the right answer with full marks. It even gives a numerical example after answering the question for extra credit!

So how exactly am I supposed to create assignments in the age of @github Copilot?

@MilesCranmer @github Yeah, ChatGPT is impressive, but what I like about Copilot is that it's already changing how I work (like in the real example below), while all ChatGPT use that I've seen is pretty gimmicky. Although I'm sure it will become practically useful soon as well twitter.com/jobovy/status/…
Jo Bovy@jobovy

@KnudJahnke @African_Dave1 @github Whatever it is, it works and its suggestions are extremely useful and good. Clearly also learns from you as you code/write and suggests create new things, like in this video where I'm using it to help write documentation and it correctly adds a new image with a relevant filename

@jobovy @github If you think copilot is good, wait until you see ChatGPT chat.openai.com. It’s even led some to declare the death of the college essay. I do think it will change student testing in some ways, similar to the internet, but the overall effect on learning will be positive.

I guess GPT-3 is old news, but playing with OpenAI’s new chatbot is mindblowing. chat.openai.com/chat We’re witnessing the death of the college essay in realtime. Here’s the response to a prompt from one of my 200-level history classes at Amherst Solid A- work in 10 seconds

@MilesCranmer @github I was mostly jokingly showing off how impressive Copilot is (and then got locked out of my account somehow). It's quite easy to ask astro coding questions that it can't answer and really I think it's great if students use it to help with coding and can focus more on physics

@jobovy @github Another idea would be to fight fire with fire... Use GPT to rapidly generate alternative APIs en masse - one API per student. Rasterize images of the API docs. Then that also solves the problem of students copying each other's code.

@cmbennett01 @KnudJahnke @African_Dave1 @github I think it is creatively changing the code in the docs/other people's repos and often getting the changes right, but it can also do funny things that aren't valid code (much of the code in this video is not valid and copilot clearly likes MWPotential2014 🎉🎉)

@jobovy Hi, Jo. We find some incorrect typos. • Below equation (12.62), the number of equation becomes "Equation{eq-closedbox-dotz}". •Below Equation (12.71), (t-Z^{Ia}_{Fe})^2 and (t-Z^{Ia}_{Fe}) may be (t-\delta t_{min}^{Ia})^2, (t-\delta t_{min}^{Ia})
