With time, some bubbles grow at the expense of their neighbors (which shrink). <br /><br />This sort of stuff happens in many everyday materials ("stuff" in the post): they contain grains ("parts" in the post) of many different sizes packed quite tightly inside them, and at high temperatures, some grains grow at the expense of the others (which shrink). While modeling this process, it's (sometimes) useful to focus only on the walls between the grains, and compute their migration. This is what we do -- I hope this came through okay in the "ten hundred word" version.Abihttps://www.blogger.com/profile/06790560045313883673noreply@blogger.comtag:blogger.com,1999:blog-9818962.post-88207128501516631772013-01-22T15:18:44.706+05:302013-01-22T15:18:44.706+05:30"All this happens, quite easily even, when st..."All this happens, quite easily even, when stuff gets hot."<br />Which parts get smaller in this case?gaddeswaruphttps://www.blogger.com/profile/16509075029154476375noreply@blogger.com
