Bead Physics


Glass Flower

A glass flower (sort of a weird material).

Often it is the simplest well thought out experiments that give the most interesting results. Like rotating a bunch of beads and seeing what happens.

My favorite part:

Why this should happen is unclear. No equations exist to describe why such a slight change in packing density should produce such different system-wide behavior. “Known mechanisms for granular convection could not be applied,” wrote Rietz and Stannarius.

I hope to find a good question like that during my science career, something simple and easy to understand that gives brand new results.
