This is a scorching article on the absolute state of The New York Times, and much of the rest of the media.
Not just the billionaire media, note, but also the billionaire-*compliant* media, which both-sides every issue with purchased junktank talking points.

This week included handling issues from the 10⁻¹¹s to 10⁸s timescales. (Debugging custom electronics on one end, and prepping for the new EU Cyber Resilience Act on the other.) I'm tempted to rewrite my resume sorted by time frame now.

Tom Lehrer has passed. At least we can take comfort that, at age 97, he died in one of his primes.

Could quantum mechanics have been invented earlier? Counterfactual questions like this aren't meant to be taken literally, but I think it's interesting anyway.

Once upon a time it was noticed that light rays follow the shortest path - for some definition of shortest [1]. This generated interest […]

Fermilab is announcing final results from the muon g-2 experiment today! I'm heading out the door, but the results will be at 10am CT. Quoting myself from April 7th, 2021:

Fermilab shared first results from their "g-2" experiment showing the Standard Model of physics is even more incomplete […]

God, the CPB responding to Trump's EO trying to end their funding with "I'm sorry, who are you again?" is really sending me.

Foreign Friends with Travel Plans to the U.S. for Conventions:

A bit back I said you should maybe reconsider those plans.

I would like to amend my prior statement.

Cancel them. Cancel them now. We cannot keep you safe from our own government. Take your holiday in Spain or something.

Many of the world’s largest shipping nations decided today to impose a minimum fee of $100 for every ton of greenhouse gases emitted by ships above certain thresholds, in what is effectively the first global tax on greenhouse gas emissions.

Which goes to show that maybe it's better when the USA […]

100 years ago, Cecilia Payne discovered what the stars are made of

It might seem obvious today, but it was just 100 years ago that we discovered that the Sun, and all stars, are made of hydrogen and helium.

We should thank Cecilia Payne for that.

For centuries, even after we knew the Sun was a star like any other, we still didn't know what it was made of. Cecilia Payne changed that.

A team of archivists has recreated the pre-Trump CDC website as a live, easy-to-navigate website that should be indexed by Google. The team is hosting it in Europe. Cool project that is sadly necessary:
