Mills' Mess upon them with varying degrees of difficulty. Mills' Mess In toss juggling, Mills Mess is a popular juggling pattern, typically performed with three balls although the props used and the number of objects can be different. The pattern was invented by and named after Steve Mills. It is a well-known trick among jugglers and learning it is considered somewhat of a milestone, "a mind-boggling pattern of circling balls, crossing and uncrossing hands, and unexpected catches." The base of this pattern is a traditional reverse cascade, (siteswap 3 in siteswap notation), with an extra "mess" added by crossing and uncrossing arms.
Collision cascade liquid flow of atoms, but if the projectile size above roughly 100,000 atoms, the crater production mechanism switches to the same mechanism as that of macroscopic craters produced by bullets or asteroids. The fact that lots of atoms are displaced by a cascade means that ions can be used to deliberately mix materials, even for materials that are normally thermodynamically immiscible. This effect is known as ion beam mixing. The non-equilibrium nature of irradiation can also be used to drive materials out of thermodynamic equilibrium, and thus form new kinds of alloys.
