Lift broken this week so the SuperNova has mostly been drinking hand hauled moonshine out of an Onion Dewar.

Did they all have their Wikipedia pages vandalised in the late noughties?

If you don't want to see a picture of my cute pet I'll have to post it to you instead.

Many thanks again to @rscadvances.rsc.org @materialsadvances.rsc.org for their generous sponsorship of our PGR Symposium poster prizes. Congratulations again to Alice Nottingham and Sean Hoggett for their terrific posters!

Love your photos of the four fold symmetric patterns in the Bahia palace! I spotted this rare example of a cheeky Kagome pattern taken in the entrance to the small Riad. People were just walking straight over it 🙄.

How much more fun would the Fourier transform be if the moons were random?

Many thanks to @benjaminchem.bsky.social for the kind invite to cross the river and visit Nottingham Trent University Chemistry to collect some diffraction data for a naughty incommensurate crystal on their rather marvelous @rigakuoxfordxrd.bsky.social Synergy-DW.

A treat for anyone that made it to the end of the thread. Happy tessellating and fast Fourier transforming everyone! 23/23

You might need a stiff drink if you've made it this far down the thread. I hope it's coming to an end. 21/999

I think I can see some systematic absences in this tiling. Or maybe it just needs rotating by 45°. 20/999

This tiling reminds me of the mind-bending card game "Set" that the group of @nchampness.bsky.social used to play in the office at lunchtime. 18/999

This tiling is called "The Wedding of the Hen" (www.atlasobscura.com/places/weddi...), and it was probably worth the journey to Lisbon alone (that and the TimeOut market). 17/999

Sometimes you put a crystal on the diffractometer against your better judgement because the researcher has pleading eyes and has tried so hard. 14/999

Sometimes you go to the lab with a functionalised polyoxometalate crystal, and you keep saying "please don't be cubic, please don't be cubic". And it is. (you both know who you are) 13/999

Sometimes you go into the lab with a crystal that you think is so full of promise, and the outcome is underwhelming in the extreme (you crystal service users all know who you are) 12/999

The script also tries a few different maths-ey things to make the contrast of the Fourier transforms pop a bit more. 11/999

Most of these transforms were actually taken of a larger tessellated images of the tilings. The script wasn't in a FEL kind of mood and needed a few more unit cells. 10/999

The Python script chooses colours from the input image to use in the Fourier transform. Maybe CrysAlisPro from @rigakuoxfordxrd.bsky.social could liven things up with a feature like this. Use colours from the video of the crystal to make the diffraction frames more realistic? 9/999

This tiling gave me the heebie-jeebies as it looks like a load of term symbols. Quick - take a FFT - ah, that's better. 8/999
