This morning I’m doing a talk in another city with a beautiful cathedral. A city whose football team is one of (I think) five current/former UK league teams that have the letter X in their name.
Intriguing dynamic sculpture at my station this morning. Or is it? It doesn’t look like it will become unstable and rotate. (Maybe that’s the point? Art, eh.)
This should help my son with his French homework.…
I always like a punny title. @BrainDropPuzzle has produced a nice variant on an old puzzle for New Scientist this week.
Just in time for #Euros2021, an updated edition of The Hidden Maths of Sport written with John Haigh, who sadly passed away in March. With our shared love of cricket, John and I agreed that all royalties of this new edition will go to the @googlyfund.…
Can you work out the scores in all the matches? My (fairly tough) Soccerdoku puzzle in this week's New Scientist.
On 30th June I'm doing a talk on "The Hidden Maths of Sport" (in part as a tribute to John Haigh). It's FREE for @Mathematical_A members, £5 for others. Details here:
I've been attempting to turn some real world problems into 'exam-style' maths questions. Hmm. It turns out that one of the joys of real world problems is that they don't tell you in advance whether they are worth 1 mark or 10 marks.
I'd particularly like to support matches between parents at neighbouring primary schools. Our programme in south-east London has been a huge success…
Great to be supporting friendly adult cricket around the country. Would love to hear of teams and matches we can support in north/north-west England…
I'll be chatting live about @googlyfund on the @BBCEssexSport cricket show this afternoon.…
This century there's been an uncanny correlation between songs in minor keys and songs that do well in #Eurovision, as discussed on @BBCMoreOrLess this week. When will the UK learn? (cc @SirTimRice @rfkharris)…
Since the 'city from the first half of the alphabet' puzzle has been so popular, here's part (b). Which UK city can only be made from letters in the SECOND HALF of the alphabet, i.e. N to Z. There might only be one.
Quiz question (posed by a taxi driver this morning): Which is the only city in the UK that can be spelt using only letters from the first half of the alphabet.
If I could have chosen the place to have my jabs, I’d have picked Lichfield Cathedral. Beautiful building, good coffee too.
Fun fact: today I learned that Altrincham isn't pronounced AltrinGAM just as a ploy to spot outsiders, it was actually spelt Altringham until the 1800s.
Bring me sunshine. Please! #morecambe
It's a little known fact that if you go to Platform 9¾ at Clapham, you can catch the secret train to Morecambe Bay. (Best commute ever, by the way).
Week 4 of school maths talks. This week Didsbury, Altrincham, cathedral city Lichfield and (frisson of excitement) Morecambe Bay.
A birthday puzzle from @AJMagicMessage to brighten your morning. (To avoid any doubt, when Martha says 'just after' she means 'within a week of'). #NewScientist
I was a guest on this week's #BBCStumped cricket podcast, talking about @googlyfund. Another thing ticked off my bucket list.…
We're doing a live in-person show on 25th June! Join @SparksMaths @stecks and @robeastaway for 'The Mathematically Curious Show' at @Ri_Science. Aimed at Year 10/12 (and Y11 if any are still around).

They aren't taught ft/inches or stone/pounds in school, it's cultural, they learn it from family, media. But I've found there's little awareness of how to convert imperial measurements to metric. "What's 100 miles in km?" "Is it about 1000?" 2/2
I reckon that about 75% of UK teenagers estimate other people's height in feet and inches. Those same teenagers typically estimate the width of their classroom in metres. Many estimate other people's weight in stone/lbs. I've confirmed this with several polls this month. 1/2
It's #NationalNumeracyDay. I'll be at @Bishop_Perrin primary school showing parents and teachers a few ways to add a bit of magic to kids' maths. I'll be taking my vintage OHP, or "magical light box" as children like to call it.
Week 3 of my free school talks. This week: Dagenham, Twickenham, Bristol and Bath. Need fresh supplies of Freddo bars, but struggling to find a newsagent that has them in stock.
How sheep rescued the classic boy-girl puzzle. My latest blog:
The title of this week's Two-Ewes-Day puzzle in New Scientist is surely the most niche pun of the week @alexbellos. (With thanks to @SuseJohnston and @emilylouise221 for sheep genetics expertise)
The launch of the @googlyfund covered in today's Guardian. First time in many years that I've appeared in an article with no mention of maths.…
Want a highly readable book to help you think critically about statistics? Back in the day I used to suggest 'How to lie with statistics'. But now I'd strongly recommend @TimHarford's 'How to Make the World Add Up' (and it's just out in paperback too).
It's my second week of free school talks. This week: Newham, Camden and Cambridge, with a mix of Year 10s, 11s and 12s, and a teacher session. First time on the underground since September.
We've had a tremendous response since we launched on Friday. Thanks to everyone who has retweeted so far and please continue to share 1/4🧵…H

Primary schools could be the saviour of "social" cricket - but maybe not in the way you think. My latest blog… #googlyfund
Part of a Chinese space station rocket is out of control and falling to earth. Nobody knows where it will land. Space Agency scientists will be anxiously calculating the chance it will cause damage or injury. Its wavy path is being tracked here… #CoreMaths
Cited in a PhD thesis for my knowledge about Jaffa Cakes. That's definitely a first.…
Enjoy playing Dobble? @standupmaths has taken it to the next level…
This is fab – Rob Eastaway is channelling the royalties from his book What is a Googly into a fund to support friendly cricket. Check this out if you know a club/player that might be eligible for a grant, and BUY THE BOOK because it's one of the best cricket titles that exists!…

Social cricket has been an important (essential?!) part of my adult life. This weekend @AnnieChave @dannyforman @Helenoutside and I are launching The Googly Fund to help others enjoy this form of the game.…

Nineteen years after it was first published, a new updated edition of "How Long is a Piece of String?" is out this week. Chapter 9 needed a *little* bit of editing.
A neat little weighing puzzle in this week's New Scientist.
I've now picked out the lucky dip schools for my free talks in May. My glamorous itinerary will include Dagenham, Lichfield, Bristol, Stratford (not the Shakespeare one) and Morecambe Bay. Sorry that some schools missed out.
It used to be the weather that we talked about. Now it's the weather AND which vaccine and side effects we have (or haven't) had, AND which holiday we aren't going on. Such a rich tapestry!
This was the verbatim second headline at 8am: "Exports to the European Union grew by 46% in February". No other context. If I were in charge of the Treasury PR department, that is the best spin I could have hoped for.…
News departments choose their headlines. The headline could, and perhaps should, have been: 'Exports were still down by over 10% in February'.
