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."

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.

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.
