Some corporate Democrats and pundits think the party has gone too far "left" and needs to readjust towards the “center.” Rubbish. Where’s the center between democracy and oligarchy, and why would Democrats want to be there?

In our course and book _Calling Bullshit_, we posit that If something seems too good, or too bad, to be true, it probably is. Now as a college professor I'm pretty confident that overreliance can AI can harm our thinking ability, but just ten minutes of use? Let's dig into this this study a bit.

Terry Tao @teorth.bsky.social: Indiscriminate brute-force application of AI to mathematics is depleting the field of good questions without renewing this resource or providing commensurate value. OpenAI: We hear you. Here's a .zip file with 377 hasty AI solutions to important open problems.

Zelenskyy: "For first time in Russia’s history, we now hear that its oil industry is running on fumes. Our target is Russia’s ability to finance this war, to drag it out, to make it more brutal & destructive. Russia’s finances & Russia’s production are what must be stopped if Putin is to be stopped”

Thinking back to the good old days when publishing a paper every three days required some human to be insecure enough to write up two ideas that didn't deserve to see the light of day every single week.

I fixed the headline. And I honestly don't understand how any journalist could write this story without mentioning the study author's own "extreme productivity".

When we talk about how science is broken, maybe at least consider how a huge collaboration measured the ripples in spacetime resulting the collision of two black holes 1.3 billion light years away, as counterweight the guy who had to fake his data to show that people who procrastinate fall behind.

And the good guys are ... (see Figure 1) ...

Gloria Steinem has passed away. Long ago, my parents used to force me to go to church each Sunday. One time the pastor made a comment about "people who were destroying America, like Carl Sagan and Gloria Steinem." I liked Carl Sagan. Gloria Steinem was new to me. I took it as a recommendation.

James Talarico @jamestalarico.bsky.social is simply 1 of the greatest, most inspirational candidates to emerge in years, running against Ken Paxton, one of the most disgracefully corrupt politicians of all-time. So the Texas GOP responds by doing what comes naturally to them, of course: CHEATING! 🤮

It's surprising (1) how many submission formats of 'top tier' journals are invite only, and (2) that they don't say so on their website, probably because it would make them look bad. Only way to find out is through knowledge beyond the website or via rejection. Are there overviews/research on this?
