I keep getting these ads on insta for a chocolate-covered licorice advent calendar, and every time I attempt to think about whether chocolate-covered licorice would be (a) good at all and then (b) good enough to want twenty-five daily morsels thereof, I just short out a little bit.

adding yet another piece of data to the "abolish business schools" file
I once knew a Federal bank examiner, and one time someone asked him why we had to KEEP inspecting banks over and over. He basically said every new batch of business school grads invents bank fraud from first principles.

The underlying cause of every bubble - debt masquerading as financial innovation - depends on not just short financial memory & speculative neophytism, but reinventing jargon of finance, like how each generation of kids has new ways to say same things.

Hey so just as a pro tip, if you try to create a bunch of indeterminate form limits off the top of your head, you should probably check for dumb typos like sign errors to make sure that you haven't fucked it up in like 6 different and equally stupid ways

Would it be fun to ask my students to prove that the chromatic number of a graph is 2 iff the graph is bipartite?

Okay, this causes me physical pain to say, but RFK is (for once) not actually being a total weirdo here. He’s a guest of the Nez Perce at a fish hatchery. The Pacific lamprey and the salmon are culturally important to the Nez Perce people, and they are lobbying to remove dams from the Snake River.
The head of health services in the United States, letting parasitic lampreys bite his arms for some godforsaken reason.

Oh yeah? No shit? The wealthiest Americans are all wacky conservatives and/or crypto-fashy? Money is a corrosive influence on your ability to give a shit about what other people think?
We spent a year investigating billionaires for @washingtonpost.com.
We found: the wealthiest 100 Americans gave $1.1 billion to influence the 2024 elections — 140x more than they did in 2000. And almost all of that giving boosted Republicans.

Oh yeah? No shit? The machine that purports to think for you doesn't actually help you think?
Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

This Utah school district is considering a four-day week as a possible cost-saving measure after failing to meet new state requirements for property tax increases, resulting in the denial of its proposed $2.8 million hike.
A four-day school week? One Utah district, strapped for cash, is talking it over.

"Quantum computing" is a lot like "artificial general intelligence" in that they are both magnets for I Am Very Smart types and that they are both, largely, given the state of current science and any reasonable predictions for the state of science in the next hundred years, pipe dreams
