There are now boxes of #CrystalExplorer kits ready to go, a FREE resource for Primary Schools in Australia and NZ. We're targeting regional and remote schools (so far reaching from Tom Price to the Chatham Islands), head to BraggYourPattern.com to sign up for one

#MosaicMonday takes us into a corridor with linear #fresco decoration and an intact geometric #mosaic floor, c. 150 CE, in the stupendous #VilladeiQuintili along the #Appia south of #Rome. The villa was the cause of its builders' death: #Commodus had them killed and took it. #AncientBluesky 🏺
MOSAIC FLOOR, C. 150-182 CE. VILLA DEI QUINTILI This massive suburban villa was built by the rich senatorial brothers Sextus Quintilius Valerius Maximus and Sextus Quintilius Condianus, who were held in such high regard by Antoninus Pius that he made them both consuls in 151 CE. Unfortunately their service and loyalty did not protect them from the envy of the last of the Antonines, Caracalla, who so badly wanted this luxurious property that he trumped up treason charges against them and put them to death in 182. He immediately took possession of the villa and adapted it to his own use; it remained an imperial property until the C6 and underwent many restorations and alterations. Here we have a short, semi-basement corridor with a simple geometric pattern of rows of black alternating triangles to create white hexagons between them, framed with a wide black mosaic border.

And here we have our Fourier transform nr. 58! As far as I'm concerned, perhaps the most enigmatic and unexpected spectrum so far... anyway, quite a spectacle! #BraggYourPattern #Fouriertransform #crystallography

As always, more on behance.net/specialdefects and instagram.com/specialdefects
A square divided in four squares, each containing strands of violet-and-blue light - some like rays, some like diffuse bands - separated by darker shady regions. Overall, these lights look like refractions coming from the centre of the image, which gets darker and darker in approaching the very middle.

A bit of an #outreach win today - orders from Flinders Island, a remote island off the coast of Tasmania, for both a Crystal Explorer Kit (for their primary students) and an Elements Set (for their secondary students)! #elementsets #crystallography #ozchem #BraggYourPattern

Time for a new 57th entry in my #Reciprocart gallery! This time we look at the frequency spectrum of a Hyperbolic tiling of triangles 📐 Unsurprisingly (for the experienced) it's a bunch of lines... but the hexagonal symmetry is visible if one looks close enough 🧐 #crystallography #Braggyourpattern
A nearly isotropic pattern of lines irradiating from the centre. The colour scheme is a fresh combination of teal, light violet and blue on a white background.

Still making my mind up if this is a good #BraggYourPattern or not - nice nod to Escher, but sort of annoys me the colour fish are sitting above the tiled layer!
Picture shows a painting from a wall at a hotel, It depicts fish that are stylised so that they geometrically fit as tiles. Fish in the background are black and while and are tightly packet together - in front of these are similar style fish but these are coloured in - green bodies and orange fins and tails.

Someone in Verona decided to make "phonon-ish manhole covers" - Approved 👌🏻 #Braggyourpattern
A manhole cover, where dots on a square grid are smoothly deviating from the square lattice, resembling a phonon in a crystal.

When diffraction data has low resolution you can always make some Rorschach Tests out of it. #crystallography #Braggyourpattern
A difference Fourier map shows red blobs surrounded by green-red-green etc. ripples, in an overall triangular symmetric pattern.

In case someone was wondering about the origin of those frequences... 😌 I admit this is pretty challenging to decipher in terms of real-space to reciprocal-space relationship, without knowing know how it is made. #FourierTransform #Crystallography #Braggyourpattern
An aperiodic tiling formed by the intersection of two square tilings of squares, one tilted by 43° with respect to the other. Many shapes are visible, diamonds, triangles, irregular octagons, and many other.

Setting out today on a road-trip with the prototype 'Crystal-A-Con in a box', all you need to keep 50 exciable primary school kids #Crystallographically entertained and informed for an hour at a time??? Wish us luck!!
An image of the contents of a box of science communication equipment. There are eight boxes of crystal explorer kit, a tube with some mineral samples, a USB microscope, 3D printed Einstein tiles, freebies puzzles and of course a big bag of jubes (gelatine sweets) and toothpicks.

A 12 petal, red-tipped flower design from a late 4th century AD mosaic set down in the dining room of #Littlecote Roman villa #Wiltshire

Found in 1729, then thought to be lost and destroyed

Found again in 1977 and still visible today

Huzzah!

It's #ScienceWeek here in Australia, and in an update we're doing fabulously in sending out our crystal explorer kits to primary schools over Aus and NZ. If you know a school that might like one - direct them to braggyourpattern.com/crystal-expl... today!
