A guy walked up to me yesterday and asked where I’m from. I said, “Just over the road”. He gave me a thumbs up and left. I guess I had the “right” answer—and “right” accent. This is just the world now? Solidarity with those who have to deal with what comes when you don’t have the “right” answer

The taste is also lovely, highly recommended.
Boosting this to the science feed🧪
very much enjoyed a great article by @maxcavitch.bsky.social in @tamarindlit.co.uk just now, in which he talks about his collection of rocks, and how they all .....taste different?!
You can read it online...but in print, its a very beautiful thing:

One of the cartoons from my new book 'Physics for Cats'. In good bookshops now and online in English, French, German and Spanish. It's also available as a print at www.tomgauld.com/

as you reduce the distance of the mass (the books) from the axis of rotation, your rotational inertia decreases. To conserve angular momentum, your angular velocity must increase, resulting in a faster spin. This is the same principle used by ice skaters to spin faster when they pull their arms in.

Sit on the chair, which can rotate freely, and hold one book in each hand with your arms fully extended. Begin spinning slowly. Then, pull your arms in toward your body. You will notice that your spinning speed increases significantly.
🧪do you have a good idea to demonstrate a concept in physics? Even a half-formed idea?

🧪 a fascinating book, about music, physics and maths...

3. The existence of tuning forks provides us with a historical reference point for tuning. And this is how we know that most of (for example) Handel's music would be considered very flat to modern ears. His tuning fork still exists and corresponds to A at 422.5 Hz (as opposed to the modern 440 Hz)
2. The lower temperatures found in Europe during the 1700s reduced the contrast between the softer summer and more dense winter growth in Spruce and Maple trees, and this seems to be have been key to the particular tone produced by the violins manufactured by Stradivarius and others in that time...🧪
Things i learned in this.... 1. Vincenzo Galilei established the relationship between the tension of a string and its frequency - and did so by experimental methods, which was surely central to his son (Galileo) later insisting on matching theory with experimental results...🧪

I was talking to a kid reader about penguins and mentioned that a "penguin scientist" had found some ancient fossils and the kid said

PENGUINS CAN BE SCIENTISTS?!

Naturally it reminded me of this pic, which I had to reshare with you all.
I'm neither young nor a woman - but I liked it!

Your occasional reminder that Ursula K. Le Guin and Philip K. Dick were in the same year in the same high school, liked each other’s writing, but never met in person.
