Cool. Positronium 'atoms' are made up of an electron and a positron.
"Researchers are [...] actively seeking tricks to make sources of positronium atoms that live longer. In a paper published today in the journal Physical Review A, the AEgIS collaboration at CERN describes a new way of making long-lived positronium."
Passively participating in #Genuary2024 — Day 8 Chaotic System. In 2012/13 I designed an award-winning audioreactive brand identity system for Leeds College Of Music based on the DeJong strange attractor with tens and hundreds of millions of particles per frame. This massive almost 1 year project consisted of a Mac/PC desktop app (written in Clojure, OpenCL & OpenGL) for exploring the attractor, creating presets and scheduling render jobs for super hi-res print assets (which would take a hours to render and were the biggest image sizes I ever had to deal with, up to 3x3 meters @ 150 dpi). I also had to develop an entire AWS based ad-hoc render farm and asset & user management system for the school to generate personalized video assets, allowing each student to upload their own music, handle audio FFT analysis and beat detection/mapping (all in Clojure) and to create individual sound-responsive clips for their in-school digital signage system and for sharing on social media... Most key aspects were handled via various old thi.ng libraries (e.g. https://thi.ng/simplecl for OpenCL interop). The server app also handled transcoding to dozens of video formats (via ffmpeg) and semi-automatic provisioning of EC2 machines for render/transcoding jobs...

Re-added/ported more agent behavior building blocks today, incl. path following and path attraction (both for open/closed geometries). In total there're now 7 freely combinable behaviors, each weighted and so usable as soft/hard constraint.
Here's an example of path following (here a Hilbert curve) and separation only...
Another example using path attraction (hexagon), dynamic targets/attractors (here changing every N frames) and a mix of the usual flocking sub-behavior ingredients: separation, alignment, cohesion
Boids now with modular behavior system, incl. newly added field-based 3-sensor Braitenberg vehicle steering behavior. In this case the field is an SDF (via https://thi.ng/geom-sdf), which is used as obstacle map with soft boundary. I'm amazed how well (and without any further help) the lil' buggers are managing to escape these concave corners...
...and now with animated obstacle SDFs working as well (aside from the major https://thi.ng/boids changes, some related useful updates to https://thi.ng/geom-sdf are forthcoming too)
#Axions are hypothetical elementary #particles that were initially postulated to solve a theoretical shortcoming of the strong interaction, the so-called strong CP problem. For many years, axions or axion-like particles (ALPs) have also been considered promising candidates for dark matter. #Physics#sflorg https://www.sflorg.com/2023/12/phy12112301.html
In the latest episode of "Nature hits the books", writer and researcher Jay Owens joins us to discuss her book Dust: The Modern World in a Trillion Particles.
Much like #dust itself, Jay’s book travels the globe, looking at the impacts that these microscopic #particles are having on the world, our health and #environment, as well as exploring the role that humanity has played in creating them.
Dear friends and visitors, I am creating this special SD image in a hurry because I need your positive energy for someone dear to me who is facing health challenges.
Thank you for spreading your positive energy. You don't need to write anything; just your positive thoughts are enough. Thank you for your attention and have a wonderful day.
Just came across the "Free Will Theorem" by #Conway and Kochen. It states that if we have free will in the sense that our choices are not a function of the past, then so must some elementary particles. And of cause logic demands that if particles cannot make decisions then there is no free will for us.
