I have others but this one has been well benchmarked over several years now. It seems to do a good job of surprising unprepared candidates!

Flowers at school 😍

Got to stop those pesky leakers!

Upon first reading, I assumed that the area of the paper was a natural constraint but that wasn't the key!

I helped a pupil with a nice example of this recently. They had a circular piece of paper and were able to make a radial cut to fold it into a cone. The problem was to maximise the volume. It's perhaps not immediate what variable should be chosen the focus before differentiating.

Lovely day at @rbgkew.bsky.social

New wedding ring is awesome! 😍

I initially read this as "damn oscillations" and wondered what they'd ever done to you! 😂

I've bought myself a new wedding ring because I struggle wearing jewellery. I thought if it was a bit more exciting, I may find it easier to wear!

I own many variations on the Rubik's cube and lots of different styles of yoyo for this reason! Me and my son are currently creating a Pokémon binder so he can learn the first 151 of them! There is something about distracting ourselves with something physical.

Thank you for this suggestion, I get some wrapped up in my own negative thoughts that doing something kind for someone else took a conscious effort. I shouldn't beat myself up about that, that's not the point!

That's helpful to hear because I often feel the need to be alone to process my thoughts, and I feel guilty about it. It's like I'm saying my loved ones can't help but it's not that.

I did 15 miles yesterday and the headphones were in the whole time! I know I'm lucky to have beautiful places close by.

Not maths but I'd appreciate input from my mathematical friends.

What do you do when life is tough, what brings you out of a period low mood (or at least helps you manage it)?

Love it!

Inset does have some perks! 😋

Great to see @jamesmunromaths.bsky.social and @oxfordmathematics.bsky.social offering TMUA prepartion sessions. Private tuition can make a big difference with these tests and anything to help level the playing fields is welcome.

Great to see this, it means lots of maths applicants, not only those brave enough to go for Oxford, will get additional free support. Thanks @jamesmunromaths.bsky.social 😁

I thought I was the only one banging on about socks and shoes 😂

Without knowledge of complex roots coming in conjugate pairs, is it clear that a quartic can be decomposed into a product of quadratic factors with coefficients over the reals?

This was going to be my original approach if hints needed. I'm on the fence as to whether to wander off track and talk about complex numbers. Perhaps I'll stick to my original plan and save the complex number fun! Thanks for engaging, I don't always get to engage with colleagues about this stuff.

It won't be a straightforward grind for the class because they will need to think about how to deal with the algebraic fraction after substitution. On reflection, I'm tempted to use this as an introduction to defining i^2=-1. Will be nice to factorise x^4+1.

This is brilliant! I can't believe I hadn't thought of using that particular antiderivative of x to simplify things.
