Monastery construction, Tibetan style

according to Swedish Designer Henry Kjellson

The steep mountain side is on the right. In the centre is the stone block, and on the left are the priests and musicians. S=big drum, M=medium drum, T=trumpeter. Inset shows method of suspending drum, and gives an idea of its size. As shown here, Kjellson says, the 200 priests are waiting to take up their positions in straight lines of 8 or 10 behind the instruments, ‘like spokes in a wheel.’ Unlikely as it may seem, this operation has an intriguing precision, made slightly more so by Kjellson’s meticulously detailed description.

Tibetan Monks levitate stones by using an acoustic levitation technique with the aid of drams in this 1939 sketch by Swedish aircraft designer Henry Kjellson.

A New Zealand scientist recently gave me an intriguing extract from an article published in a German magazine, relating to a demonstration of levitation in Tibet. After obtaining a translation by a German journalist, in English, I was amazed at the information contained in the story, and was surprised that the article had slipped through the suppression net which tends to keep such knowledge from leaking out to the public.

Digital morphogenesis

Digital morphogenesis is the exploration of how shapes, forms, and patterns emerge in nature through the use of computational modeling and generative systems based on biological, chemical, and physical processes. It draws upon research from practically every area of the natural sciences and has applications in architecture, digital fabrication, art, engineering, biomedicine, and more.

With such a cross-disciplinary topic it can be hard to keep track of and correlate all the interesting bits of knowledge that one comes across, which is where this list comes in. The goal of this list is to succinctly catalog various growth algorithms and lab experiments along with relevant math, physics, and programming concepts in one place in order to (1) serve as a sort of “cheat sheet” reference for developers and computer artists, and (2) spark new insights by making it easier to see relationships between seemingly disparate topics.

Contributions are always welcome! If you’d like to add a description for any topic, or have some interesting and relevant links to share, or know of a topic that should be included somewhere in this document, please feel free to open an issue or a PR with your changes.
