β€œHack-a-thon” and β€œtaxes” do not belong in the same sentence.

Canada, make sure to keep the Cons out of power so we don’t have to deal with similar stupidities. #canpoli

I don't just want to see Pierre Poilievre and the CPC lose, I want to see them so crushed that no major Canadian party ever flirts with or supports the extreme right again. Every vote against the CPC and PPC matters. Be sure to vote. Send them and the world a message.

Columbia has conceded academic freedom. The subject of, nature of and response to the protests aren’t directly relevant; the US administration is now dictating what the affected departments can research and teach.

Awesome news. Rubin is the scientist perhaps most closely identified with the discovery that galaxy rotation cannot be explained with Newton’s law of gravity applied to the gas and stars they contain. This led directly to the idea that dark matter dominates the gravity of galaxies at large radii. πŸ§ͺ

Trump's ONLY interest in 'peace' in the Russia - Ukraine conflict is that he thinks it will net him a Nobel Peace Prize. He would be a shoo-in for the Nobel Stupidity Prize if it existed.

I often do not agree with Globe & Mail columnist Andrew Coyne, but he really nails it with β€œThe United States has handed the nuclear codes to a madman, a criminal, a would-be dictator and a moron, all in the same person.”

The latest AI models use 10^26 FLOPS (floating point operations) in their training. This is equivalent to running the Apollo Guidance Computer that took humans to the moon for 79 trillion years

The first measles death in the US in a decade -- the tragic, preventable death of a child whose parents chose not to protect them with vaccination -- should spark an immediate nation-wide campaign to ensure all children are protected against preventable diseases. Anything less is unconscionable.

ChatGPT can give you inspiration. I had it write a short, short story about a murder at a AAS meeting where the culprit was Bryan Gaensler. I sent it to him and he sent back Vol 2 where more evidence came out at the trial and the actual culprit was yours truly

Helmut Abt, stellar astronomer, former ApJ editor, and one of the founders of Kitt Peak National Observatory, passed away today at age 99. Helmut played a large role in setting up KPNO, a new concept at the time of a publicly open facility, offering telescope time based solely on scientific merit.
