So, kurz vorm Frühstück fertig: die #Kaustik des Parabolspiegels.
Links ein #Buckyball als "Gegenstand", mittig das "ideale Bild" (gemäß Konstruktionsregeln für ein perfektes System). 4 Strahlen gehen aus, werden reflektiert, leicht hinter dem idealen Bild gebündelt.
Das rote Band gibt nun die Bildpositionen aller Objekte an, also "die Verzerrungen im Foto".
I still haven’t had much chance to carve this year, or catch up with the #PrinterSolstice prompts, so until I can, here’s a carbon-themed print from my portfolio: Millie Dresselhaus (née Spiewak; November 11, 1930 – February 20, 2017). She was a professor of physics and electrical engineering at MIT, known as the Queen of Carbon Science.

Happy birthday to Millie Dresselhaus (née Spiewak; November 11, 1930 – February 20, 2017). She was a professor of physics and electrical engineering at MIT, known as the Queen of Carbon Science.
In this linocut I've shown her in front of a carbon nanotube. She was recognized for her work on graphite, graphite intercalation compounds, fullerenes (a form of carbon known as buckyballs, 🧵1/n

I think I already answered this. I believe they are "#BuckyBall" joints.
Slide some sticks or tree limbs into them to easily build the framework for a portable shelter.
The protruding "balls" would make it easier to slide the completed structure into place across the ground.
Much easier to carry around than entire tents with poles & canvas.
(If I'm right, they predate Buckminster Fuller's invention by a couple of thousand years.) 🤔

Der Buckyball musste heute endlich mal gebaut werden. Teamarbeit eines Oberstufenkurses in der Chemiestunde.
Basic Post-It notes are square, or close enough to it, to use as origami paper, and they make great PHiZZ units: https://duckduckgo.com/?t=ffab&q=phizz+units
I made a #buckyball over the course of a week or two while waiting for code to compile or other build tools to run. (Yes, many of our tools are....verrrry....slow....)
".. vermutet, dass im All sogenannte Fullerene und deren Abkömmlinge entstehen können – grosse Kohlenstoffmoleküle in Fussball-, Schüssel- oder Röhrchenform. Ein internationales Forschungsteam hat .. gezeigt, wie diese Reaktion abläuft... Pressemitteilung des Paul Scherrer Instituts (PSI)."
