The talks from the @vsac2022 conference symposium I "Realities of Geometries" are now online. If you are interested in #MathArt and #illustratingmath, give them a look here: youtube.com/playlist?list=… (10-15 min. per talk). A short presentation of the talks as thread🧵. (1/5) First talk is by me, @msmathcomp. I am speaking about the generalization of #Chladni figures to the third dimension. Thereby, the intersection of sound waves becomes tangible, e.g., in the form of a #3dprint. . (2/5)

#Subdivision schemes don't only help finite element methods. In a recent paper, we present a #mathart application of creating #weaving patterns from said schemes. Furthermore, we extent these patterns to create a #jigsaw puzzle. Here's a thread.🧵1/13 doi.org/10.1080/175134… Computer simulations for, e.g., the weather, solve complex problems on a 2D domain. They mostly do so by splitting the domain into a finite set of smaller and simpler elements on which the simulation can be run fast and efficiently. This uses subdivision schemes. 2/13
