I gather these vortices arise within the medium at some remove from any real physical boundary and any constraints to movement are internal and integral to that medium. <br /><br />Is it legitimate to say that the vortices are nature’s way of containing more energy within a given space?<br /><br />There is a Don Fosterhttps://www.blogger.com/profile/04814669413022486958noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-89972819122356809402012-10-21T08:29:25.945-04:002012-10-21T08:29:25.945-04:00Hi Karén,

Can a "higher excited state" be created, with say 4 of them.<br />Also, it would be interesting to see how the picture would change gradually if transversal direction is allowed to be non-zero. Probably, depending on viscosity,<br /> the vortices will survive until certain size, butAnonymoushttps://www.blogger.com/profile/16398782926648781879noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-35446121438367481692012-10-20T07:45:40.294-04:002012-10-20T07:45:40.294-04:00LOL:-)
