Off on holiday and about to start my second sketchbook so here is a little glimpse of my first one. #sketchbookclub

I’m bringing the Big Maths Gameshow to @LeicsComedyFest @KidsComedyFest @niscifest this February half term, with some new bits for 2025. Get involved! #leicester #derry #family #maths

🥶 Puzzle 1 : Frosty Equations🥶 Solve the equations to find the values of ❄️, 🥊 and 💎: ❄️ + ❄️ + 🥊 = 7 ❄️ + 💎 + 🥊 = 12 ❄️ + 💎 = 9 Found the solution? Vote below! 🗳️ #NationalPuzzleDay

🧩 National Puzzle Day is 29th January! 🧩 To celebrate, we’ll be sharing puzzles and problem-solving tips throughout January 🧠 Stay tuned for hints, tips & solutions! 👀 First up: frosty simultaneous equations! ❄️ #NationalPuzzleDay

Puzzle 2: Icy Inversion 🧊 This triangle points up (like a mountain 🗻) What is the least number of snowflakes which must be moved so that the triangle points down (like this pizza slice 🍕)? Vote below and reply with your pics & reasoning — we’d love to see your ideas! 🧠👇

Happy 175th Birthday Sofia Kovalevskaya! 🎉 The first woman in modern Europe to earn a doctorate in mathematics and the first female professor in Europe, Kovalevskaya made significant contributions to PDEs and mechanics, including the Cauchy-Kovalevskaya theorem 🪐⚙️

1️⃣ Alex: “Flo and I are different types of people.” 2️⃣ Omar: “Jing is a resolution-breaker.” 3️⃣ Jing: “Omar is a resolution-breaker.” 4️⃣ Flo: “At least two of us are resolution-keepers.”

We’ve included examples below. Got a solution? Share it with us — we're eager to see your ideas! 🧠👇#NationalPuzzleDay

Puzzle 4: Cool Convexity 🆒 Can you draw a set of 7 points A-G in the plane such that: 🔹 ⟨A, B, C, D, E, F, G⟩ forms a triangle 🔹 ⟨B, C, D, E, F, G⟩ forms a pentagon 🔹 ⟨B, C, D, E, F⟩ forms a quadrilateral?

Been enjoying our National Puzzle Day posts so far? Here’s the final puzzle — and it’s a tough one! 🌰 In fact, this one’s a specimen exam question from one of our most popular modules MST368: Graphs, Games & Designs (sorry not sorry)

Now that you’ve seen all the puzzles, it’s time to get to work (if you haven’t already)! 🧩 Remember, we’ll be posting tips, hints and solutions all the way through January — so keep an eye out! 👀 Have fun puzzling and don’t forget to share your progress and solutions with us!

💡 You could also try the substitution method. We’ve seen some savvy solvers already crack it — what method did you use? Share your approach below! Good luck, and happy puzzling! 🍀

How’s it going with our #NationalPuzzleDay puzzles? Need a hint for Puzzle 1: Frosty Equations? 🥶 1️⃣ Subtract equation 3 from equation 2 — this is called the elimination method. You’ll discover that 🥊 = 3. 2️⃣ Consider equation 1…how might knowing 🥊 = 3 help?

2️⃣ Pro tip: Sketch the triangle using different colours for each row or use coloured counters to make a moveable version. It’ll make tracking your moves much easier! 🎨 Good luck, and happy puzzling! 🍀 #NationalPuzzleDay

Yesterday, we shared a hint for Puzzle 1: Frosty Equations. Today, let’s tackle Puzzle 2: Icy Inversion! 🧊💡 1️⃣ Focus on the vertices — a single move here has the biggest impact on the triangle’s orientation. Check out a (possible) first move below 👇🏻

Did somebody say funfair? That's right, alongside delicious food, a colourful parade, therapeutic workshops, and community stalls, we also have a funfair filled with thrilling attractions!​ Come along to our free festival, Art in the Park 2024, on Saturday 13th July.

Prof Mark Brandon (@icey_mark) was a guest at Windsor Castle on Tuesday, collecting The Polar Medal, which was awarded to him in recognition of his outstanding work and contribution to the scientific knowledge of the Polar Regions. Congratulations Mark! ounews.co/around-ou/univ…

MKIAC's @AnouarKassim & Caroline - ambassador were invited to celebrate #CreativeIndustries at the #BuckinghamPalaceGardenParty, graced by Her Highness, the Duchess of Gloucester, Hazel Edwards-the Arts Council South East Area Director, and Claudia West-the Director Cambridge.

Just had some writing published, open access, in ESM: link.springer.com/article/10.100… ... arguing for the importance of thinking about the socio-ecological state of the planet in our teaching ... @TFrancome @WebbMaths @ATMMathematics @ddmeyer @forestimaginatn @_TeachtheFuture @joboaler

Lovely day to be in Bristol to give a talk at the @SOEBristol celebration day with @TLC_Bristol. Looking forward to seeing all the posters and presentations.
