Someone has pointed out, quite rightly, that I really should tag @standupmaths when I mention a video that he has made.
I'm not sure appearing in a video counts as a connection for an Erdős number, much as people might hope it might.
So ... the monostable (or self-righting) tetrahedron:

Episode 5 of #Un-NaturalNumbers the maths chat show just dropped. In what is arguably our largest number so far: 5. Join me, @hopeiona.bsky.social and Jocelyn to discuss our favourite facts about the number 5. #mathschat #mathsky #msthstalk youtu.be/i-oAWhc5SH0

If I say: Any square (4*4 or 8*8) may be rotated by 90 degrees, if the pieces are fully enclosed in the square. Is it possible to sort all the greens to the left and reds to the right? #playmaths #mathschat #mathsky

Every polynomial with real coefficients factors into linear and quadratic terms.
How much machinery is needed to show this?
If it crosses the X-axis then it has a linear term.
If it doesn't cross the X-axis then it is of even degree, and the roots come in complex conjugate pairs.
What the minimum needed to see this?

I've been thinking about this for ages, but never had the time to craft the words around it.
People keep saying that "Maths should be fun" ... and I push back with "It should be engaging ... 'fun' is a different thing.
So @rakhichawla has posted pretty much exactly this, but better than I ever could.
I'm copying it here with permission.
Please read this, then as it says at the end ... let's have a deeper conversation about this ...
1/n
(PS: I'd love this to get boosted to get outside my bubble ... you're all amazing, but there will be other opinions, and other thoughts that could be helpful or valuable)

Fermat conjectured that for \(n\) a non-negative integer, all numbers of the form \(2^{2^n}+1\) are prime.
Was there ever a worse conjecture in maths than that?

Some time ago ... (A month!) ... there was a thread on Twitter that I think should be shared here. I've been trying to extract and post it semi-automatically, but Twitter just makes it damn near impossible.
So I'm copying it "by hand"
Here's a chart of the full conversation:

Have a look at the first intersection of y=cos(x) and y=tan(x).
Consider the tangents at the point of intersection:
What is the angle between them?
What are their gradients?

Two lines, 𝓁 and 𝓂, both have positive slope.
The angle 𝓂 makes with the x-axis is twice the angle 𝓁 makes.
The slope of 𝓂 is nine times the slope of 𝓁.
Find the slopes of the two lines.

Dissect a square into two pieces whose areas are equal, and whose perimeters are equal to that of the original square.

@samjshah Fabulous!
Once they've joined it would be useful to have a consistent hashtag. Some that have been used already include:
#MathChat #MathsChat #MTBoS #MathEducation #MathEd #education #teachers
It will be great to get the math teaching community here and get some cross-fertilisation.
