Are quasicrystals thermodynamic ground states? I wrote a News & Views piece for @natphys.nature.com on the work of Baek & coauthors, who used DFT (density functional theory) with clever extrapolation to show that there is strong evidence that two quasicrystals indeed are ground states. rdcu.be/eqRPM

NATIONAL TRUST EMPLOYEE [inside cabin]:
Hello there

[A young family - two parents two kids - have arrived at the front desk].
DAD:
Hi - do you have an activity trail, for the kids?
3
NT EMPLOYEE:
Of course – you’re just in time for the Autumn Gammon Trail!
4
MUM:
That sounds fun, doesn’t it kids?
5
NT EMPLOYEE [handing an activity sheet and pencils to the kids]:
Every autumn, the Reform Trust gammons flock back to the National Trust for the AGM. Just follow the trail round the grounds, and see how many you can spot!
6
NT EMPLOYEE [hearing something in the gardens]:
Listen - that's their call
[Calls emanating from the landscape]:
tut-tut
woke-woke
7
NT EMPLOYEE [showing the family an apparently empty fenced enclosure with some bushes in]:
They are extremely sensitive and fragile...
But you can bring them out of hiding if you put a little sign down mentioning slavery.

KIDS [pointing]:
There they are!
[Some little red faced PEOPLE wearing Barbour jackets and gilets emerge cautiously from the bushes. They are creeping towards a TINY SIGN in the middle of the enclosure].
[Little people noises]:
woke-woke
tut-tut
woke-woke

[Close-up of the TINY SIGN - we can read that it says]:
Slavery had a bit to do with building this massive house.
[Noises from the little people again as they inspect the tiny sign]:
tut-tut

MUM [pointing]:
What's that one doing there?
NT EMPLOYEE:
Oh, that's so sweet…

[We see that one of the people is sat on a rock, with a little laptop open on a tree stump, and they are furiously typing away].
NT EMPLOYEE:
I think he's writing a column for the Daily Telegraph…
