COUNTDOWN. Still can’t believe this happened, but you will now be able to watch me attempting to do maths live on television for the next 3 weeks, starting Monday at 2:10pm @Channel4. So excited to be joining the @C4Countdown family - long live daytime television!!

A glimpse behind the scenes of the excellent recording session with @tomrocksmaths for the @twinklresources "Leading With" podcast today where Tom shared his insights into engaging people in mathematics, as well as what he learned from sitting school level exams during lockdown

Are you even a tourist in Sri Lanka if you don’t take the train ride to Ella? Simply breathtaking. It took 7 hours and 20 minutes to travel from Nanu Oya to Colombo at an average speed of 28 kmph. How long is the railway? Try without a calculator for a challenge :)

Loved catching up with Prof. Alison Martingano and talking about how to overcome maths anxiety on the Psychology & Stuff podcast @uwgb. We went to the same high school but hadn't seen each other in 20 years... amazing to reconnect after all this time! https://t.co/Zzm4Z6K2r3

Linguistic Fossils take the win over the Birthday Problem - well done again to @susie_dent Keep a lookout for a full video explaining 23 + the Birthday Problem - coming soon :) In the meantime catch up on all 11 rounds of "Numbers vs Words" so far here: https://t.co/Hyyo5in2C8

NEW VIDEO: The Kissing Coins Problem - what is the smallest circle that encloses three touching coins? Premieres today at 4pm (GMT). See you in the live chat! https://t.co/tLycwWYobw

Fascinating conversations with some of the greatest minds in Mathematics at the HKLF - what a couple of days it's been! 1. Reinhard Genzel (2008 Shaw Prize & 2020 Nobel Prize) 2. Nigel Hitchin (2016 Shaw Prize) 3. John Peacock (2014 Shaw Prize) 4. Simon White (2017 Shaw Prize)

Back at the Hong Kong Laureate Forum to interview 4 Shaw Laureates over the next few days. Love visiting this city, especially the harbour - and just look how pretty the ship (called a junk) looks with the skyline <3

Sigiriya Sri Lanka. An ancient rock fortress built in the 5th Century. The hydrodynamic system connecting the water gardens is phenomenal, not to mention the lions paw, and views at the top of the 1200 steps. If I climb 90 steps per minute how long does it take to get to the top?

Dambulla Cave Temple - a UNESCO World Heritage Site since 1991. The temple dates back over 2000 years and contains painted murals over an area of 2100 square metres. The largest cave has dimensions of approximately 50m x 20m x 3m, so can it all be painted?

Making new friends at Kaudulla National Park in Sri Lanka. A 2008 study by the University of Tokyo showed elephants are capable of adding together small numbers by counting apples and selecting the bucket with more in. I knew there was a reason they were my favourite animal <3

Hello Sri Lanka! Had a lot of fun exploring Colombo and seeing the sights. The mix of architectural styles from colonial Portuguese, Dutch and British, alongside buildings influenced by Buddhism, Hinduism and Islam, plus modern skyscrapers, really is spectacular.

Happy Halloween Maths Fans!! I promise only to haunt your dreams with scary mathematical puzzles… Can you work out which one is me in each photo?

HERE ARE YOUR STUDENT WINNER[S] I couldn't decide so selected 2 essays as joint-winners of the 2025 TRM Essay Competition. Congratulations to Amelia Tan and John Winmill-Briggs for their winning essays "A Tangent about Tangents" and "Coprime by Chance". https://t.co/vnstmWQ6I9

Very excited to announce we will be running the Vice-Chancellor's Colloquium on Climate for a third successive year @UniofOxford, which includes some mathematical modelling from yours truly. Open to all Oxford undergraduates - register your interest here: https://t.co/zjJ62p9gUP

Some highlights from my Comedy Show @Oxford_IF on Sunday evening. Award-winning research has never looked so ridiculous! Thanks to everyone that came along for laughing at my jokes… even the bad ones.

NEW VIDEO: Round 11 of Numbers vs. Words 23 from @tomrocksmaths vs. Beck and Call from @susie_dent. The birthday paradox against linguistic fossils - which is your favourite? Cast your vote here: https://t.co/a8825F8Ilf https://t.co/Ji5cW9cI52

@cs50 Tickets @Oxford_IF here:

According to these lovely shots from the @cs50 Puzzle Day, I must be hilarious. Which is good news, as I'm doing a comedy show at the Oxford Bullingdon this Sunday delving into the world of "award-winning research". Come along if you're free and hopefully learn a thing or two :)

Having a blast in Belfast! The perfect way to end my tour of Northern Ireland for @mathsweek. Thanks to @PwC_UK and @QUBelfast for hosting in such spectacular venues - until next time :)

LOOK AT THAT VIEW. The library tower ​⁠​⁠@StEdmundHall is the perfect place to spend an afternoon writing about Pokemon battles for my upcoming book on Fantasy Mathematics. What are your favourite type matchups from the games?
