For the mathematicians :
There is one major flaw in the graph (from Canada).
What is it, and how can the graph be improved ?

The "Football" / "Soccer" debate reminds me of Trigger out of Only Fools and Horses.
Most of the rest of the world: "Football"
The US: "Soccer"
Everyone else in OFAH: "Rodney"
Trigger: "Dave"

Maths-related: Usually pupils are taught to add and subtract mixed nos. via improper fractions. But what happens if the whole nos. are more awkward ? Do we stick with improper fractions, or do we do the whole numbers separately, with "risk" of carrying and borrowing ?

#RachelRileyRR If I were to dictate this GCSE-style question to a group of people, would some of them work the answer out as 17 instead of 15 ?

Most people will give the correct answer as 15 to this modified GCSE question when they see it written down, but if I were to dictate it to them, quite a few might give the answer as 17. I wonder why !

A very disturbing reminder of an evil policy that came from an Austrian-born person who became a German leader under a century ago.

One common cold coronavirus - OC43 - began as the Russian Flu of 1889-1891 according to several sources.
Possibly Covid-19 will become an endemic winter common cold in the next year or so.

I was looking out at the night sky tonight and thought I was seeing double-double. The Twins (Castor and Pollux) appeared to have doppelgangers in the same area of sky ! The doppelgangers were Mars and Al Nath (Beta Tauri).

@GylesBi @susie_dent Found an old word game called "Bali" in the attic. It's a cross between Scrabble and patience and deserves more attention, as it's a good game of skill.

Following on from the last tweet, the area in square metres is about 5.6 times the square of the side length in metres. Also , the square was the wrong answer when maximising the area for 3 sides. It's half a regular hexagon, or about 30% bigger than the square.

This GCSE-style question can be solved correctly, but there's also a joke solution due to a blunder.
