Advent calendar 2025—day 24: The Light
From Adolf Luther’s acrylic-glass lenses in Krefeld to microscopes and telescopes, lenses make light—and worlds from particles to galaxies visible. As this Advent calendar comes to a close, our gaze turns to the Star of Bethlehem.

#ScienceArtTechAdvent
Advent calendar 2025—day 17: The Plastic
1960 brought Maiman’s ruby laser (pulsed) and Javan/Bennett/Herriott’s gas laser (continuous)—now guess the iconic plastic architecture in Germany linked to 1972 and tell us in the comments.
#ScienceArtTechAdvent
Steel can be cut with laser technology with extraordinary precision. And not only that: it’s also possible to cut very thick steel plates. This process was used for the sculpture next to me by Bernhard Müller-Feyen from 1996. The work was cut with a laser from a steel plate 10 cm thick (about 4 inches). If you’d like to learn more about laser technology and laser research, I recommend the book Laserforschung in Deutschland 1960 bis 1970 (“Laser Research in Germany, 1960–1970”) by Helmuth Albrecht, published by GNT-Verlag. You’ll find the answer to today’s question in that book: In what year was the first laser completed? But you can figure it out without the book, too.
Advent calendar 2025—day 16: Laserblade

Lasers don’t just paint the night sky—they can slice 10-cm (4-in) steel, like Bernhard Müller-Feyen’s 1996 sculpture; can you guess the year the first laser was built?
#ScienceArtTechAdvent
Advent calendar 2025—day 15: And there was light
Tagblatt Tower—Stuttgart’s 1927–28 New Objectivity high-rise, first exposed-concrete skyscraper, once glowed with Moore gas-discharge tubes; what light did Moore sneer was “too small, too hot, too red”?
#ScienceArtTechAdvent
Starting in the late 1920s, Stuttgart already had a modern 61-meter-high tower as a landmark. At that time, people were still genuinely enthusiastic about technology. The newspaper Stuttgarter Tagblatt ran a headline for its opening that read “Stuttgart empor!” (i.e. “Stuttgart Rises!”) And contemporary artists did not march against this modern building; instead, they made it the subject of their work—as did Max Ackermann, for example, in 1928 who created a drypoint etching. So which tower am I talking about? And which construction method, one that shaped both the aesthetics and the engineering of the structure, was used here for the first time anywhere in the world? Here’s a little hint: ChatGPT knows the answer.
🎄🔬🎨 Advent calendar 2025—day 14: Rising towers
youtu.be/9tlT-CXHf24
From Le Corbusier’s Ronchamp chapel to Stuttgart’s pioneering TV tower and an earlier 1920s landmark: can you guess which structure changed tower design worldwide?
#ScienceArtTechAdvent #LeCorbusier #ConcreteTower #StructuralArt
Today’s question is about a building, completed in 1955, in which creative drive, the laws of construction, modern structural engineering, and pure functionality all merge into one. As a clue, I’m showing you a 1997 study by Peter Christian Reimann of this very building. Because of its organic impact, the structure has become an icon of modern architecture. Architecture buffs will recognize it instantly anyway. For everyone else, here’s one more hint: since 2016 it has been listed as a UNESCO World Heritage Site and is located in France. That should be enough help. I’ll reveal the name of the building tomorrow.
