The girls have done well today! Or in the language of Richard Scarry "Big, bigger, biggest".

My paper representation of a chemical structure. Each loop represents a silicon atom in strontium disilicide. The structure is a 10^3-a network (AF Wells) but known as the srs-structure (if you're a MOF person). Most interestingly it has a chiral cubic symmetry. 🧪 🐡 #MathArt #ChemSky

Made a start. It should grow out to give a chiral cubic 3-connected network made up of 10-gons. #MathArt #SciArt

Been thinking about this structure for a while. Building blocks cut and ready!

5/5 (at last) 120-Deltahedron A. That's 60 blue and 60 yellow equilateral triangles that break the reflection symmetries of this Mobius deltahedron. Just the many 5-fold, 3-fold and 2-fold axis remaining. 🧪 🐡 #Symmetry #MathArt

Set complete.

A work in progress. If I don't finish it tonight, it'll be another week!

4/5 120-Deltahedron B. Icosahedral symmetry and 120 faces. The three corners of each triangle sit on a 5-fold, a 3-fold and a 2-fold rotation axis. Next year, I'll be involved in teaching a symmetry course at Glasgow. I'm quite excited by the prospect. Can you tell? 🧪 🐡 #Symmetry #MathArt

3/5 This third one in the series is 48-Deltahedron B. Octahedral symmetry again, and an isomer of the previous post (2/5). As far as I'm concerned, that's the last relatively simple one! 🧪 #SciArt #Symmetry #MathArt

2/5 is 48-Deltahedron A. The second Mobius deltahedron with 48 faces. Octahedral symmetry, meaning each triangle has a corner on a 2-fold, a 3-fold and a 4-fold rotation axis. Again going for two-tone. 🧪 #Symmetry #MathArt #SciArt

1/5 This is 24-Deltahedron A, a 24-sided non-convex polyhedron, made of equatorial triangles. It is face-transitive and has tetrahedral symmetry. The corners of the triangles lie on 2-fold and 3-fold rotation axis. It is the first so-called Mobius deltahedron. 🧪 #Symmetry #MathArt #SciArt

A paper model representing the fullerene C70, colloquially known as Rugbyballene. 🧪 #ChemSky #ITeachChem #SciArt

Still making paper models of fullerenes. These represent the 7 IPR isomers of C80. 🧪 #ChemSky #SciArt

Charles Janet's version of the periodic table is often lost in the history of science. I for one, prefer it. #ChemSky 🧪

Not posted for a while. Not made much for a while. Too busy with the day job...dotting the i's and crossing the t's on the academic results from Year-3 Chemistry. Just a couple more board meetings until that part of the process is complete. Image: a two-tone weaving of C80...just because.

To be fair I should have shown what it's like to weave folded paper.

Daniel Price@danieljprice.bsky.social · 2mo ago

The weave, added creases, blue lines for bonds, and it's a model of C60 fullerene. Potential #SciCom 🧪 #SciArt

REMINDER: Global heat waves are FOSSIL FUEL‑driven climate chaos. Recent research shows that warming linked to the world’s biggest oil and gas companies has made EVERY major 21st‑century heatwave more intense and more frequent.

11:30 pm in Argyll (#Scotland) looking north, and we're still a month away from the longest day. Many newts, toads and frogs ( and roe dear) this evening.

Eldest son had the brilliant idea that we should hatch ducks! We're at 6 weeks with these Silver Appleyard. #NewFeatheredFriends

The two disconnected void spaces, separated by the card, are identical and interpenetrating. Each has the shape of the framework of carbon atoms in the structure of diamond. 🧪 #ChemSky #PaperCraft #SciArt

Dramatic skies today on our ascent of Beinn a' Mhanaich, quite foreboding across to Loch Goil. #Scotland #StormHour

Duck update: What are we feeding them? Hatched 4 weeks ago!

Still on a fullerene adventure. Unflattened a network of regular hexagons and given the impression of electron density with contours. It represents a molecule of (C80-Ih)[56]fullerene. #ITeachChem 🧪 #ChemSky #SciArt

I live in a very busy and neurodiverse household. I get a lot of push-back from my kids. I find I'm constantly having to defend all sorts of random positions or points of view. On the plus side it keeps me on my toes, but on the down side, it's exhausting.
