This kinda blew my mind.
I know that there is something profound about this but I cant wrap my tiny little mind around it.http://www.discussworldissues.com/fo...milies/eek.gif

Here's another mind boggling physics trick...

The Navier-Stokes Equations for the velocity in a compact vector notation (top) and

the equation for a density moving through the velocity field (bottom).

Mathematically, the state of a fluid at a given instant of time is modeled as a velocity vector

field: a function that assigns a velocity vector to every point in space. Imagine the air that

occupies a room, its velocity will vary due to the presence of heat sources, air drafts, etc. For

example, the velocity of the air near a radiator will predominantly be pointing in the upward

direction due to heat rising. The distribution of velocities within a room is also quite complex as

is evident when watching the smoke rising from a cigarette or the motion of dust particles in

the air.The Navier-Stokes Equations are a precise description of the evolution of a velocity field

over time. Given the current state of the velocity and a current set of forces, the equations tell

us precisely how the velocity will change over an infinitesimal time step. Figure 1 (top) depicts

these equations in a compact vector-like notation. Very roughly the equation states that the

change in velocity is due to the three terms on the right hand side of the equal sign.

Can someone translate that is less beefy people wordshttp://www.discussworldissues.com/fo...milies/eek.gif

That was fun reading http://www.discussworldissues.com/fo...es/biggrin.gif
