Factorio mod turns streamer into a Solar Opposites character
Переглядів 391Місяць тому
I was watching a Factorio playthrough and thought that this part sounded a lot like a Korvo rant. Here's a link to the original stream: ua-cam.com/video/8hRJ-CcwvrI/v-deo.html (the clip starts about an hour in). I am not affiliated with the streamer or with solar opposites, but I'm fairly certain that this video constitutes fair use.
Rotor Routing Consistency Animations

This video has several clips meant to accompany the slides for my talk on rotor-routing consistency, which can be found here drive.google.com/file/d/1W4MZQ6ZvllV0iz1V8vmpfeqdbSkVCyRz/view?usp=sharing. Note that there is no sound in the video. 00:00 Clip 1: Single-Chip Rotor-Routing 01:10 Clip 2: The Unicycle Perspective 01:45 Clip 3: Multiple Chip Rotor-Routing 02:22 Clip 4: The Sandpile Group ...
The Rotor-Routing Sandpile Torsor: A Case Study into Research Mathematics
Переглядів 5823 роки тому
I wanted to share my area of research with a wide variety of math enthusiasts! Learn about chip-firing, sandpile groups, and the matrix-tree theorem in our quest to find a sandpile torsor! This is also my submission to the Summer of Math Exposition. Thanks Grant Sanderson for putting the event together and for all the inspiring work you do! Thanks also to Brilliant for sponsoring the contest. L...
Nice video introducing a research topic to a wide audience! Coming from a physics background, would sandpile torsors have applications for optimization problems in systems with a conservation law? I noticed the number of chips in each graph is conserved.
"It has more names than a sheet of paper with six names on it." 😀 (Well, now this video has more comments than a video with six comments.)
Great video! Hope it gets more attention as people make their way through the 3B1B playlist.
This is great! I was just starting to look into sandpiles on my own, and this gives me some intuition. Graph!
Thanks Mostly Mental! Have fun learning about sandpiles!
great video, keep going
Thanks for this, Alex! Appreciate the animations that show how the algorithms play out
