Yes, my wedding has a website
Yes, I have also included modelling of the expected temperature on the day
Yes, I did this by fitting a Bayesian model to 45 years of temperature data
Yes, the wedding website has an easter egg with a little link to find a writeup of how I got the numbers

One criticism of mathematicians is that they always seem to have an answer for everything. Nothing is beyond their reach.
Absolutely right. Take the Christmas menu for example. @joshuabull.bsky.social is your waiter.

I reckon you can learn a lot about the atmosphere in various Oxford colleges by looking at what they choose to name their cats (courtesy of @oxfordclarion.bsky.social ). We should all aspire to the energy of a Teabag, Isambard Kitten Brunel, or an Admiral Flapjack

Great to see some exciting applications of #MuSpAn in action in @pathologop.bsky.social's talk at #ESSB2025 today!
Come and say hi if you'd like to find out more about the software, or to have a chat about how MuSpAn might be able to help with your data analysis :) #EMBLSpatialBiology

Lots of opportunities to chat about #MuSpAn at #ESSB2025 this week!
In the Wednesday poster session go find Josh at p151, and come and talk to me at p58 on Thursday!

We're exploring spatial biology at multiple scales here today - the auditorium is huge, but the powerpoint presentation is several orders of magnitude smaller

Just pulling into Heidelberg for #EMBLSpatialBiology #ESSB2025... Really looking forward to meeting more of the #SpatialBiology community this week!
If you want to chat with a friendly mathematician, do say hi if you see me wandering around, or drop me a message on here and we can coordinate :)
