Dr Tom Crawford

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!!

@AnnDooms @VUBrussel SO cool!

Very honoured to be featured in El País 💃🏻😍 #lifegoals #mathematics @VUBrussel

It may have been hotter than a thousand suns but always a pleasure to host an event at the Sheldonian Theatre - it’s just so pretty! Thanks to everyone that came along to the VC-Colloquium Finale and huge congratulations to all of the finalists :)

It may only be by 4 votes but I am absolutely taking the win for round 20 of Numbers vs. Words. 42 may be a little bit of a cheat code for the maths-based audience but it was pushed all the way by the scientific measure for smell. Watch all 20 here: youtube.com/playlist?list=…

NEW VIDEO: youtube.com/shorts/6DsjECq… Rock - Marry - Kill, Millennium Problems Edition: Riemann, Navier-Stokes, P Versus NP. Which do you rock? Which do you marry? Which do you kill? Here's the right answer, but what do you think?

WHAT A DAY. Thanks to Dr Josh Smalley for inviting me to Science Kitchen to make the perfect mixture of maths, baking and science. You’ll be able to watch the entire process of cake baking and attempted Platonic Solid biscuit assembly, on my YouTube channel - COMING SOON!

@blondgavster We had a Robinson version last term so I think it’s just highly college dependent

@tomrocksmaths Nice. We never had subject dinners at my college, though it was in the other place! Is this specifically an Oxford thing?

St Edmund Hall Maths Dinner 2026 - one of my favourite dinners of the year as we bring together all undergraduates, masters students, PhD students and staff for an evening of excellent food and even better conversation. Good luck to all of you with exams in the next few weeks!

If you've ever wondered how we make sense of powers of infinity, this is for you. What is infinity squared? TRM intern Tavish Gera provides a great explanation by way of example through the Cartesian Product and the Cardinality of a set. Read here: tomrocksmaths.com/2026/05/20/wha…

Tattoo 76 - Central Limit Theorem. An incredibly useful result in statistics that says the sample mean for ANY distribution will look like a Normal if your sample size is large enough (usually around 30). So helpful it almost feels like a cheat code…

Today’s teaching notes courtesy of the University of Cambridge and my supervisions at Robinson College. There are two courses shown here - one 1st year and one 2nd year - can you work out what they are?

NEW VIDEO: Watch me have far too much fun talking all things Pokémon for my 2025 TEDx talk. I've read all 1025 entries in the Pokédex and picked out 5 of my favourites that seemingly break physics. Premieres today at 4pm GMT+1 - see you in the live chat! youtube.com/watch?v=VOTOMG…

Having a blast at Whitgift School earlier this week applying mathematical modelling to my favourite fictional worlds. We may have failed to catch Mewtwo but now we know exactly how to improve the catch probability for next time!

NEW VIDEO: youtube.com/shorts/1Bsrp8Y… Do you know which three cube numbers add together to make 42? Or what the scientific unit is for measuring smell? Round 20 of Numbers vs. Words has got you covered. Watch at the link above then vote for your favourite: forms.gle/31mfBYbQYUFisu…

Can you solve these 'simple' algebra problems? Filip Moons excellent lecture as part of the EMS Mathematics Education Series looks at the importance of teaching algebra to help students to avoid common mistakes. I definitely had to think carefully about some of these questions!

Brilliant day filming with Miss Estruch Biology in Oxford with St Edmund Hall looking particularly lovely in the spring sunshine. Video of me taking a GCSE Biology exam coming soon! (yes I don’t know why I figured this was a good idea either… :p)

We were delighted to welcome renowned #mathematician Dr Tom Crawford @tomrocksmaths to ISM! 🇬🇧 He shared insights with parents on inspiring a love of maths, met students, and led workshops across Primary and Secondary. We thank him for an inspiring visit!🙏

@numberphile Looking forward to it!

Sending big thanks to all our Patrons - you make Numberphile possible... numberphile.com/patrons Some nice bits of bonus content coming your way soon, BTW

Had a fabulous time today @ISMonaco talking all things fantasy maths. Spent the rest of the day exploring Monaco and found a great example of cannonball numbers in the wild. If there are 15 cannonballs at the bottom of the square pyramid, how many are there in total?

Running around Monaco pretending I’m a Formula 1 car vroom vroom… Monaco is the 2nd smallest sovereign state in the world - you can probably guess the smallest - but has the highest population density of any country at ~26,000 per square km. Which others make the top 10?
