There\u2019s a structural avalanche waiting inside that box of Rice Krispies on the supermarket shelf. Cornell researchers are now closer to understanding how those structures behave \u2014 and in some cases, behave unusually.<\/p>\n
The researchers, led by James Sethna, professor of physics in the College of Arts and Sciences, have for the first time rendered a model for crackling noise in two dimensions. Their paper, \u201cUnusual Scaling for Two-Dimensional Avalanches: Curing the Faceting and Scaling in the Lower Critical Dimension,\u201d was published Oct. 30 in Physical Review Research<\/em>. The paper\u2019s lead author was Lorien X. Hayden, M.S. \u201815, Ph.D. \u201819, and co-author was Archishman Raju, M.S. \u201816, Ph.D. \u201818.<\/p>\n Milk enters Rice Krispies through a process known as \u201cfluid invasion,\u201d which is similar to the oil industry\u2019s method of pumping pressurized water into porous sandstone to push out oil. The resulting noise \u2014 the cereal\u2019s famous \u201csnap, crackle and pop\u201d \u2014 is a type of tiny \u201cavalanche\u201d that indicates a burst of milk invading pores in the puffed rice. Each avalanche is essentially composed of smaller-scale versions of itself, a proportionality shaped by \u201cpower law\u201d distribution. Crackling noise also describes earthquakes, magnets and many other systems.<\/p>\n","protected":false},"excerpt":{"rendered":" There\u2019s a structural avalanche waiting inside that box of Rice Krispies on the supermarket shelf.
