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.

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 […]

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.
