Welcome to all the newcomers to #ChemSky 🧪
I don't post much, but you'll get a dose of #compchem and materials discovery, a bit of #machinelearning (with skepticism) and some sprinkling of #Pittsburgh (including @pitt.bsky.social and @pittchem.bsky.social)

Thank you. Do you think you can convince our Senator over in Braddock?
Seems like all that $$ going to ICE could go towards things people actually want.

Sandy Asher passed away a few days ago. His memorial will be tomorrow.
"He will be remembered not only for the discoveries he shaped, but for the way he helped others approach the mysteries of life with humility and wonder."
And his laugh.

Yes - I add it as another tool for them, particularly when problems get bigger (e.g., who's going to solve a big matrix by hand?) or when there's no easy formula.
Student feedback has helped - I try to balance "let's use pen and paper" and "send this one to Jupyter"

Right now we're using JupyterLab through the browser, so it's harder to do that.
But I'll definitely know on their assignments. If they use any LLM, it'll suggest syntax we haven't used yet.
I'm *hoping* it means that they're willing to put in the effort, but it'll be an interesting semester

I'm trying an experiment this term. I teach a "Mathematics for Chemists" course for undergrads, including some basic coding in Python.
Most students come in with little or no coding experience. So I prepped a custom chatbot -- it just gives hints and asks questions.

In other words, rather than accept a union, the current owners closed a newspaper that’s almost as old as the US.
The Post Gazette was killed today because the Blocks, after fighting the longest strike in US history at 1,133 days, were irrevocably told by the Supreme Court today that they lost. So they're closing a newspaper that first published in 1786 because they're mad.
