Of beer and bubbles: The formula for a perfect pint<\/em><\/strong><\/p>\n By Julie Steenhuysen Thu Apr 26, 9:13 AM ET<\/p>\n CHICAGO (Reuters) – A mathematical formula can now predict how the frothy head on a beer changes over time, a finding that may have a wide range of commercial uses beyond pulling the perfect pint, U.S. researchers said on Wednesday.<\/p>\n The formula explains how the tiny bubbles that make up foam grow — an explanation that could lead to the development of products such as metal shrink wrap.<\/p>\n The possibilities include “the heat treatment of metals or even controlling (the) head on a pint of beer,” Robert MacPherson of Princeton University in New Jersey and David Srolovitz of Yeshiva University in New York report in the journal Nature.<\/p>\n Foam is made up of many tiny bubbles that scientists think of as cells with boundaries. The new formula calculates how these microstructures grow.<\/p>\n These tiny structures or grains are abundant in nature, making up the foam on a beach or the pebble in your shoe. They also can be found in man-made materials such as ceramics or metals.<\/p>\n “What the theory does is it tells you how the size of every single bubble will evolve in time,” Srolovitz said in a telephone interview.<\/p>\n David Kinderlehrer, a mathematician at Carnegie Mellon University in Pittsburgh, said the finding will help materials scientists concoct a number of newfangled materials by rearranging the grains in various materials using computer simulation.<\/p>\n “It tells you how an individual grain grows by itself until something happens to it. That is very important for understanding how to process material,” Kinderlehrer said in a telephone interview.<\/p>\n In metal, that means striking the right balance.<\/p>\n “The strength of a metal depends on grain size. As you make smaller and smaller grains, the metal gets stronger and stronger but it also gets more brittle,” Srolovitz said.<\/p>\n “For a particular application you want the grain size that represents a compromise between as strong as you can get and as brittle as you can live with,” Srolovitz said.<\/p>\n Kinderlehrer said new materials now under study are batteries that do not corrode and shrink-wrap metals that could be used to repair nuclear power plants — without shutting them down.<\/p>\n “A lot of things we can only imagine,” said Kinderlehrer, who wrote a commentary accompanying the study.<\/p>\n","protected":false},"excerpt":{"rendered":" For all of those math geeks out there, here’s an article that you may enjoy.
