in #MathsToday, Y9 worked on versions of @studymaths.bsky.social's Multiplication Grids modified to include negatives. Then we moved on to equivalent fractions, where I put a fraction on the board and they had to put an equivalent on their board that no-one else also had...

This is a photograph of the edge of one of Saturn's rings, looking down from above. Those spiky dark shapes are shadows. Shadows of giant towers of ice and dust grains clumped together that rise up to three *kilometres* above the 10-m thick rings.

A series of bands cross the image from left to right, brighter at the bottom and darkening towards the top. A band of empty space is at the top of the image. About a quarter down from the top is a complex pattern of jagged, spiky shadows cast onto the rings. The icy towers casting the shadows are seen here at a highly oblique angle.

1941. It was references to the needs of"the present time" and "Armed Forces" that gave it away for me. And, of course, the "student" could only be male.

#MathsToday Found in a charity shop... Can you guess when it was first published? Last century, clues in the Preface.

The cover to the book, "A Short Practical Mathematics" by F.G.W. Brown

PREFACE

ONE effect of the intensive use of mechanisms which is characteristic of the present time is a demand for a minimum of knowledge of the elementary processes of mathematics and their practical application. The student is often prevented by lack of time and opportunity from undertaking a full course of practical mathematics, but that is no reason why he should be debarred from gaining, or revising, sufficient knowledge of mathematical principles and operations to enable him to use intelligently the machines he has to operate.

This book has been prepared for such students. It makes no claim to be a full course of practical mathematics, and it will be obvious that mathematical nicety has had to be sacrificed to the needs of the hour; it is believed, however, that it will provide those entering the Fighting Services or engineering courses with just the knowledge of mathematical principles, and exercise in their use, which are needed. Special attention is given to the use of contracted methods of working, and there are chapters on numerical trigonometry and elementary mechanics.

Just finished "Nuclear War: A Scenario" by Annie Jacobsen. An amazingly gripping book. Rigorously researched, told in an unflinching style that reminded me of the recent "A House of Dynamite". Feels strange to recommend, but if you get a chance, read it. And let's hope it never happens... #BookSky

I've just added the Algebraic Identities / Comparing Coefficients / Algebraic Fractions tasks I made back in 2022 to interwovenmaths.com/algebraic-id... My favourite part is these discussions, where [spoilers] you can show that 42 and 9 are in fact the only options, each with a nice interpretation.

$Two algebraic fraction identities labelled a and b, asking which is easier. The coefficients 42 in a and 9 in b are highlighted in purple$ $Two follow-up algebraic fraction identities labelled c and d. Question c asks why the identity with 14 highlighted is impossible; question d asks which other values of the highlighted coefficient d are possible.$

#MathsToday Year 10 had a go at maths4everyone.com/'s "Strengthen" sheet on Angles in Parallel Lines, having spent last lesson on the"First Steps". Really pleased with how they handled these tricky questions, and there was a real sense of achievement at the end.

"Pythagoras" by Kitty Ferguson, has been sat on my TBR list for years. I wish I had read it earlier. The story of Pythagoras' life alone is amazing, and probably nothing like what you think. The journey into the influence he had on the history of the world since is fascinating. #BookSky #MathsToday

Back from our jaunt to London. Had a great time, ate well, thought Beetlejuice the Musical was hilarious, and enjoyed the sights of the big city. But wow, was not prepared for the amount of people still smoking. That Proustian whiff took me back, and not in a good way.

Lots to enjoy at the @sciencemuseum.org.uk in London today. But my favourite part was this Apollo capsule simulator, used by Apollo astronauts. Simply because you can see that this was working kit, annotated (I hope) by the astronauts themselves. Always show your working! #MathsToday

Just finished "Tehanu" by Ursula K LeGuin. This is a master storyteller who is not willing to just give us what we may think we want from EarthSea, and instead enriches the world by considering how ordinary lives can hide the most extraordinary people. A dark but brilliant tale. #BookSky

Today is Venn Day, in celebration of the mathematician John Venn, born on this day in 1834. To commemorate the occasion, here’s a poem in the form of a Venn Diagram.

Poem title: At the Intersection

The poem is divided into two overlapping circles.

The left-hand circle is titled ‘me’ and the text reads:
the day we
went out to have
an ice-cream, we said nothing
just let our silence melt in
the air as we walked across the common
our love never tiring at all

The right-hand circle is titled ‘you’ and the text reads:
we should
have talked it over but
nothing ever seems to get
in your fat head. You are so
common that I wish we’d never met
at all and I’d married Tim instead

In the intersection of the poem (where the two circles overlap), the text reads:
we
have
nothing
in
common
at all

Think the next lane is moving faster? Maths says you're probably wrong. Most traffic jams aren't caused by crashes – they're created by tiny braking differences that ripple backwards into "phantom jams." Smooth driving beats aggressive driving every time. Randa Herzallah explains
