original: more formally , vorticity can be related to the amount of " circulation " or " rotation " -lrb- or more strictly , the local angular rate of rotation -rrb- in a fluid .
simplifications: more officially , vorticity can be connected to the amount of " circulation " of " rotation " , or more precisely , the local angular rate of rotation , in a fluid . more formally , vorticity can be related to the amount of " circulation " or " rotation " -lrb- or the local angular rate of rotation -rrb- in a fluid . vorticity can be related to the amount of " circulation " or " rotation " in a fluid . vorticity can be related to the amount of circulation or rotation in a fluid . more formally , vorticity can be related to the amount of " circulation " or rotation " -lrb- or more strictly , the local angular rate of rotation -rrb- in a fluid more formally , vorticity can be related to the amount of " circulation " or " rotation " -lrb- or more strictly , the local angular rate of rotation -rrb- in a fluid . more formally , vorticity can be related to the amount of " circulation " or " rotation " -lrb- or more strictly , the local angular rate of rotation -rrb- in a fluid . more formally , vorticity can be related to the amount of " circulation " or " rotation " -lrb- or more strictly , the local skinny -lrb- so you can see bones -rrb- / having angles rate of rotation -rrb- in a fluid .
