@PhilRodgers @MTansini91 @ElectionMapsUK Could be this one. Delivered to Girton and supposedly based on 'the latest local elections across the constituency'.

[Queen Mary Maths @QMULMaths]

A very big welcome to everyone joining the School of Mathematical Sciences this week. We hope you have a fantastic year and we look forward to meeting you all!

[Robert Johnson @robert77johnson]

@MartinHGAnthony @LSEMaths Best of luck Bernhard. I hope you stay looking as relaxed and cheerful as this throughout your reign!

[Robert Johnson @robert77johnson]

Good to see another diamond open access journal in combinatorics being launched. I hope it will be a great success.

[Centre Mersenne @Centre_Mersenne]

Welcome to "Innovation in Graph Theory", a young open access journal on graph theory and its interactions https://t.co/iMW98bPcSr which joined Mersenne!

To whet your appetite, here is a personal account of the last BCC from two first-time participants

Check out this write-up of the @UKCombinatorics conference by two of my PhD students on the @QMULMaths Combinatorics Group blog.

The British Combinatorial Conference is coming to @QMULMaths!

Interesting thread with some great pictures on the #CambridgePeregrines.

Seeing these birds is always a reminder of the mountains -- much-needed in such a flat place as Cambridge!

[Cambridge Peregrines @camperegrines]

Hello to all our new followers! It’s been quite a year for the #CambridgePeregrines - in fact, 2023 has been their most successful breeding season to date. Here’s a thread that explains their story so far… 🧵

[Robert Johnson @robert77johnson]

@wtgowers Sam Mattheus has a nice post on his blog which gives an overview of the main ideas in the proof:

@graphaellamulas As a combinatorialist, visiting Budapest (and especially the Renyi Institute) always feels like a bit of a pilgrimage! Hope you had a great trip .

[Murray Edwards College @MECCambridge]

All at Murray Edwards were deeply saddened at the death on 3 May of Vicky Neale, a much-loved former Fellow of the College and a passionate champion of mathematics, especially for girls. Our tribute to Vicky, ‘an exceptionally vivid person’, is here: https://t.co/D4eWCc5P5w

@mjelihoreau @SouthbankSinf @max_fosh What a lovely video. Very funny and surprisingly uplifting too!

Well done @SouthbankSinf and Max for making this happen.

[Robert Johnson @robert77johnson]

For London based combinatorialists, here is an opportunity to hear about the exiting recent developments in Ramsey Theory:

Big thanks to @CUHandH for a well-organised race with friendly marshalls, a (mostly) well-marked course, and copious food en route and at the finish (if there is a hot cross bun and jelly baby shortage in Cambridge this week you know who to blame!).

[Robert Johnson @robert77johnson]

Fun but tough morning at the Cambridge Boundary Run yesterday. Happy to get under 3:30 despite pacing it terribly and really struggling at the end (amidst the mud, hills and headwind).

#cambridgeboundaryrun, #marathon

[Robert Johnson @robert77johnson]

As usual, a really interesting line-up of speakers for the annual London Colloquia in Combinatorics.

@QMULMaths, @LSEMaths

[Robert Johnson @robert77johnson]

@BristOliver Fair point. Playing this game round here is probably cheating.

[Robert Johnson @robert77johnson]

@BristOliver A couple more in a similar vein for your collection

[Queen Mary Maths @QMULMaths]

We've got a really exciting guest speaker for our next School Colloquium.

Prof. Lauren Williams from @HarvardMath is giving a talk on combinatorics of hopping particles and positivity in Markov chains.

Full details below, everyone welcome!

@NewtonInstitute @BBCInOurTime This was indeed a great listen. Just to make sure full credit is given, Andrew Treglown (@MathsBirmingham) was also one of the contributors.

[Queen Mary Maths @QMULMaths]

Today is International Day of Women and Girls in Science.

Last year, we spoke to female mathematicians @QMUL about their participation in mathematics and how we can create safe, collaborative, engaging spaces.
