Fun fact from the Tech, Bugs & Rock'n'Roll podcast: the first transatlantic cable was burned out by an idiot boss who demanded the voltage be turned up for some reason. It took 8 years to replace.
At the beginning of those 8 years Abraham Lincoln was a lawyer. At the end of those 8 years Abraham Lincoln was dead. The whole Civil War played out without transatlantic telegraphy, even though it had already been invented.

Any #Fusion360 experts out there who can give me some advice on what seems like a simple thing but also seems to be impossible? (Basically changing the radius of a compound curve "fillet", but without the design history.)

If you're in Scotland expect an emergency alert on your mobile in the next few minutes. Storm warning for tomorrow.

Signed up to a bass tutorial thing - first thing I look at which would be useful to me (etudes) is a paid extra. Bit annoying. But then I open up the available tabs, and there's an awesome version of the Ghostbusters theme at exactly my level...so we'll persevere...
And it seems like a nice community for a few pounds a month, let's give it a go. First time I've paid to be taught bass (I owe you a few drinks, @gahlord), be interesting to see how much benefit I get.

The astounding thing about this for me is how the dogs seem to have developed a really good sense of proprioception about where their wheels are, so they can avoid stuff, like humans driving vehicles.

There's lots of science fiction stories about a single molecule being able to "infect" other matter. Ice-nine, grey goop stories, Borg/Cyberman nanoparticles, Strange matter etc...
But this is real, and scary. A particular crystalisation of an HIV drug was able to "infect" labs and production plants, making the drug useless.

"38% hydrochloric acid" (~12.4M) as you buy it, is a pretty rough estimate. And it needs a fume cupboard and goggles etc to handle, so once a year or so I make a few litres of roughly 4M, then I can use that to make the 2M, 1M, 0.1M etc that we use daily.
As long as know the actual "4M" concentration (e.g. 4.17M) I can do accurate dilutions, so I check with a titration when I make it.
Did my annual batch today. 4.00M
Sheer fluke.

@Theorem_Poem Is there an equivalent to a "Sunday roast" in your bit of the world? Not a big celebratory meal, but something a little more extravagant than the usual dinner, for a group, maybe once a week or three?

Remember that (hopefully satirical) Victorian era cartoon of a piano which played by the hammers coming down on the tails of different sized cats?
I'm not entirely convinced that doing it to music students with a piano controlled paintball gun battery is much better...

Question on a school science technician forum today that seems to produce a reasonable consensus - and I tried it on my 6th years and they basically agreed:
What colour are biology, chemistry and physics? Either gut reaction or full on synaesthesia?

OK, finally, some common sense from Google. Now, if you could also stop using AI for my searches about hazardous chemicals, radioactives, laser safety, and give me a nice big "do not let AI interact with anything I do" button, that'd be lovely.

Great question from a younger student today: "...but if oxygen is needed for something to burn, and there's no oxygen in space, how does the Sun burn?"
Taking a couple of things they know, an observation, and going "hang on a minute...", nice.
