Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
Hey r/physics! I'm a materials science PhD student, and over the weekend I got to set up my favorite materials science demo, that I'd only ever seen before as a grainy black and white movie from the 50s. Before scientists could see atoms in microscopes, they used models like this raft of bubbles to understand how defects called dislocations wander through crystals to produce plastic deformation and bend the material. I hope you think it's as cool as I do!
Literally studying this right now for my Material Science final tomorrow!
This was really awesome dude, great work
Would be amazing to have a 5-10k particle simulation widget that allows you to play with this and drop in different size spheres.
I'm not sure if anyone is familiar with Falstad but he seems like a person who would do this.
I think processing can handle a simplified energy calculation for each particle now, no? I could be wrong.
Subscriber! Your videos are amazing! Your passion and enthusiasm always make my day.
If there were lectures on solid-state physics like this in my University, I would visit them definitely.
Your channel is underrated. I hope you get to millions. Keep the good work up.
Thanks! This was really awesome, great job
I subscribed after the Steve Mould shoutout and watched this last night!
