Physicists from Berkeley say they ;ve figured out the insanely complex math behind the way bubbles pop when they ;re in a foam 鈥?and they ;ve got an extraordinarily accurate video to prove it. The math behind a single bubble popping is relatively straightforward. Scale that up to a cluster of foamy soap bubbles, on the other hand, and you ;ve suddenly got something that considerably more complicated. Unlike a single bubble that pops in isolation, clustered bubbles work off each other to produce a complex set of physical events that span both space and time. When one bubble pops, the other bubbles quickly rearrange themselves to balance out the cluster. This sets off a cascade of forces that influence the overall configuration of the cluster and the timing of subsequent pops. Given all this complexity, physicists have struggled to accurately describe the behavior of foams with equations. S
