リプレイスするなら
①24-70/2.8 GM2 発展的統合としては妥当なのだけど、所詮F2.8だから、これ出すくらいなら単焦点2-3本な気がする
②24-60/2.8 多分下取りでお釣りが来るから有力だけど、最短撮影距離など考慮すると20-70/4のままでいい気がする
③24-50/2.8 軽量ショートズームは結局小さな単焦点着けたほうがトータルの取り回しがいい
と、決定打に欠いて千日手が続いてる

if, like me, you can't shake your coffee addiction, i highly recommend shaking it up instead. try adding oat milk so you can enjoy both the appearance of mud and the flavour of mud.

#EU and the #internet: one step forwards, one step backwards.

I wonder if identity checking requirements would become irrelevant if the #web was peer-to-peer, with individuals being publishers and data controllers at the same time.

Lie groups and Noether's theorem are the tools that let 20th-century physicists wield *symmetry* as a powerful tool to study crystals, molecules, atoms, and elementary particles. Lie groups let us describe symmetries that can vary continuously, not just discretely. Noether's theorem shows how these continuously varying symmetries give conserved quantities like energy, momentum, angular momentum and others.
But what is a Lie group? This Quanta article does a pretty good job of explaining the basic idea. One quibble: they say
"The group of all rotations of a ball in space, known to mathematicians as SO(3), is a complicated three-dimensional shape that lives in nine-dimensional space."
That makes it sound more complicated than it really is! I'd rather say
"The group of all rotations of a ball in space, known to mathematicians as SO(3), is itself a ball with each point on its surface glued to the opposite point."
If you're gonna scare people, I feel you might as well scare them with a puzzle they can actually chew on. I guess that's why I'm not a journalist. If you say "a complicated shape that lives in nine-dimensional space", most people will feel this is utterly beyond their powers to understand. And in a way, that's relaxing: it means math is only for geniuses, not them, so they can stop thinking.
But if you say "a ball with each point on its surface glued to the opposite point", people may say WHAT THE HELL???
I feel journalists don't want that. As a blogger, that's exactly what I *do* want. You may be able to figure it out (it's easy with a picture). But if you've got questions, I'm happy to answer them.

The #MastoPrompt for Friday 5 December 2025 is:
The poem or story can include the prompt word or be about the prompt word.
@ me, if you like, or just include the #MastoPrompt tag (to allow people to follow or filter their feeds), or keep your work to yourself - all the options are good as long as you're writing.
If you're including an image please do include alt-text if you’re able to.
