Hey, I note that the upper powerlaw appears to contain all sizes that are multiples of four, and the lower curve contains all the others! Could this be related to the fact that one avalanche moves four grains? If so, could it be that your code only returns a non-multiple-of-four size if a grain falls off the edge (confirming your hypothesis that it's an edge effect)? I wonder if you'd see just the upper powerlaw if the x-axis were "number of local collapse events" (i.e. one count per collapse instead of four).
Is there away to link two of these applications together? For example: predator spread and lifeform flight or extinction? So as the predator adds his 4th grain to a stack there could be a link to producing a 4th grain „spontaneously“ in prey behavior also, which would e.g. drive the lot of prey to another area? Maybe under certain circumstances at that point then even 3 grains of prey could be enough to evalanche. best regards and thnx for the video
Hi Andrew! Love the video. :) I'm a high school student interested in precisely this topic. I was wondering if I could contact you and ask you a few questions - if you have the time. I would greatly appreciate it. Thank you!
Appreciate the video. One thing, perhaps for future videos. It’s pronounced: aww-tom-a-tawn. It kept producing a dissonance within my mind, given the semantics associated with “automation” are meaningfully different.
Looks like he's using matlab (edit: nvmd, apparently in his writeup he says it's python + matplotlib, a python package for producing matlab-like plots)
Hey did you use my project to help you? If so, that's awesome! If not, incredible coincidence as your figures look almost identical! You can see my writeup here: github.com/blairg23/Bak-Tang-Wiesenfeld-Sandpile-Model/blob/master/Writeup/sandpile.pdf
Yes, absolutely! I am glad it helped you out! I think you did a very good job of explaining the pieces I was missing too!

You should enhance your power law plot... it looks very bad... You have to go to bigger system sizes to really see the power law (if you implemented the model correctly)... Otherwise it will seem contradictory with the idea of "criticality"
simulated sand pile is one of the best clips on youtube
This was a very cool video, and thanks for making everything so easy to under-sand 😎
Nice work, well explained!
Impressive work.
Do you have references for the papers from Chicago and Oslo? Would be greatly appreciated.
6:53 what if one horn is caused by the little avalanche and the other caused by the big avalanche?
Thanks - nicely done

The great San Francisco earthquake was in 1906 :P love the visuals, great vid
Angle of a pile is it same always? Can it be connected with other phenomena in nature and in science?

Actual Sandpiles, epic

Hey I just came across this video a few years later, and I was curious how your studies have been going. How have you been?
I'm curious as well ^^
What’s with the impurity of your sand buddy?
Appreciate the video.

how you did the simulations? is it in C/C++ or some advanced software?

Blariana, I did refer to your thesis! Is it okay if I add your github link to the video description?
Yes, absolutely! I am glad it helped you out! I think you did a very good job of explaining the pieces I was missing too!

i personally believe in divinity and creation but thanks for this video i enjoyed it
