Ok but why did I write this? #HoagieHomies
Aside

Sometimes this theorem is called the Sandwich Theorem, since the upper bounding function and the lower bounding function act as the slices of bread, while the strangely behaved middle function acts like the toppings on the sandwich.

We choose not to use that naming convention in this text in order to preserve the flexibility of the definition of a sandwich. An open-faced sandwich is still a sandwich (in the opinion of the textbook author), but this result clearly doesn’t hold when we only have one bounding function.

At the point of the semester where the grading is in its full cycle now. I'm drinking tea and reacting completely normal about it, no need to investigate further

Hilarious paragraph, a group overwhelmingly votes to try to have more power in negotiating their jobs and this guy complains and instead of realizing that, wow, maybe these people have a point, he's mad they didn't ask for his opinion and they aren't as split on their own opinions lol
Is unionization of postdocs on the rise? Yes. Has there been much thoughtful discussion in the scientific community of the consequences? No. On March 26, the Yale University faculty were notified of an impending vote on unionization by postdocs—but no date for a vote was announced. A second email, on April 20, announced the election on April 29 and April 30. No comments were solicited. So much for seeking informed opinions before acting. On May 1, we received a third email from the provost. Not surprisingly, the postdocs had voted to unionize. In a tally reminiscent of Pravda, we were informed the vote was 859 to 31. So much for diversity of thought.

Here's the part of the syllabus that I just read verbatim to them in class.
A Note on Generative AI and LLMs

The short version of this note is, simply, “Don’t use them.”

The medium-length version of this note is that this course is one that will require you, first of all, to think deeply. The course includes calculations, computations, and other things like that, but most important is the deep thinking we’ll do about the objects we learn about, the properties of them, and how they interact with each other. There is no practical, helpful, or ethical way to use generative AI and large language models to accomplish or assist with this.

In fact, any use of generative AI and large language models in an attempt to create something for this course is antithetical to the purpose of the course itself: to get you to think deeply about, and learn, the mathematics topics we’re working through.

I promise you that in whatever task or process you consider, these tools will do a less-than-good job and reduce your opportunity to think deeply. Mathematics is a communal activity, done by communicating with each other. While I hope that this class reflects this, I implore you to choose human communication whenever you might otherwise decide to use a tech company’s forgery of dialogue.

For the long version of this note, or for some ideas of productive alternatives to whatever you might think to use a generative AI tool for, please visit me in office hours or send me an email. I’d love to talk with you about ways that we can reduce our reliance on the tech industry.

Last, and equally important, I ask that you respect me and the work I’ve done by refraining from inputting my textbook, course notes, activities, practice problems, or examples into these tools for any reason.
