Independent news item today:
https://www.independent.co.uk/...ctures-b2396476.html
with the headline "Mysterious hidden structures hundred of metres deep discovered on dark side of the Moon"

The headline is more interesting than the news item though so nothing like a monolith

Well there's something I didn't know......that the moon was originally a piece of the Earth.

Maybe these structures are an ancient ancient Stonehenge

No need to apologise, Moonie
Maths was by far and away my best subject as school. I failed my English and my English Literature O levels first time at school and had to retake the, When it comes to foreign languages I am incompetent at any of them.

Now woodwork and metalwork I was good at

I‘ve still got things I made at senior school, which is more years ago than I care to remember

I've mentioned before about getting a book prize for getting the top marks at school for a Shakespeare quiz we did during the Easter break, On the day the prizes were to be handed out, for some reason I was in the school workshop where they did woodwork classes (not that I was in one of those classes) and managed to cut one of my finger tips with a Stanley knife. Dashed off to where the school nurse was to get bandaged up once the blood had stopped. So there's me getting the prize with a bandaged finger, having my photo taken, with the photographer motioning towards me for some reason. Turned out that I was holding the book upside down
Still got the book and the scar can still be seen after all these years.

El, that’s a gem

I’m pleased you got your prize, upside down or not

Here's a poser we were given at school.

It's known as Morley's trisector theorem.
For any triangle, trisect each of the 3 angles M, O, R. That means to split each angle into 3 equal angles so M is split into 3 alphas (Îą), O into 3 betas (Îē) and R into 3 gammas  (Îģ).
When Îą and Îē meet on the left side is point L. Where Îą and Îģ meet on the bottom side is point E. Where Îē and Îģ meet on the right side is point Y.
Draw straight lines from L to E, from E to Y and from L to Y to make a new triangle,
The poser is to prove that for any triangle MOR, the small triangle LEY is always an equilateral triangle, i'e. the lines L to Em E to Y and L to Y are the same length and each angle is 60 degrees.

Describing the poser is one thing. Trying to prove it is far harder. I did attempt it many years ago and gave up..

Frank Morley....now there's a man with too much time on his hands

It's easy to see when explained...

Although we were told about this at school,it wasn't part of the syllabus and we weren't told about how to prove it.
There are youtube clips on various ways it's been proved but one would need to be a mathematician to be able to understand them.
