Fulltime freelance provider of outreach and enhancement in maths ... I talk a lot. About maths.

I talk about other stuff too, like ballroom dancing, juggling, unicycling, education, engineering, software, and "other things".

But mostly about maths.

"Astronauts could run round ‘Wall of Death’ to keep fit on moon, say scientists"

There's a heading that is actually an accurate reflection of the article content and the science behind it:

Is this deliberate? The "mistake" means it's getting a lot of free repeats.

Is it AI generated?

So many questions ...

I marked a word in this, didn't commit it, stared for ages to see hoe to complete the area around it, then realised it was wrong!

So I'm really happy with this result:

Re camera problems ...

Apologies to all ... problem solved.

I've vigorously unplugged and replugged all the cables multiple times, and now it seems to be working!

Bizarre!

I will delete this thread ... apologies to anyone who has lost any time over this.

I think this should be required reading for every student in secondary school, from Year 10 onwards.

Every year.

Make every person aware of it.

Asking for a friend(*) ...

"I need to brush up on some Pure Maths for a thing, and I find I'm pretty rusty. Can any of m'Maths friends recommend a good book on rings and ideals, and that end of algebra?"

(*) No, really ...

Someone on forged in fire said he gets anxious over lots of things, like spilt milk, and hairy lemons.

Hairy lemons?

@andrewt Hello ...

I have a friend (who is not imaginary) who has a thought about a variant for ...

He says (paraphrased): ...

"... could implement a hard mode, where each puzzle is based on a random reading direction. (Left-to-right, right-to-left) x (top-to-bottom, bottom-to-top). I’ve kind of got my eye in now for L2R,T2B. Plus vertical direction before horizontal.

"I was thinking about word searches and how they had complexity by reading in non-obvious-order."

I recognise that you've probably moved on and don't especially want to tinker, but if it's easy to implement, maybe it's a thing to try.

Thoughts?
