Another martial point to make note of...
What was the secret behind Wakefield's pitching? The knuckleball - when it is thrown correctly - has been described as "a butterfly with hiccups."
What's the deal here?
Well what the pitcher does is throw the ball in a manner where there is little to no spinning. As such, the circular object essentially becomes aerodynamically unstable. Mathematically speaking, it is chaos in real life. Just the slightest imperfection on the speeding object - like the seams on the ball, will cause it to take an
unpredictable path away from straight forward. To some extent, neither the pitcher nor the catcher will know where the ball will end up; chaos means you cannot predict this without knowing initial conditions to an infinite degree of precision.
So what does that have to do with martial arts? Well "rifling" vastly improved the range and accuracy of projectiles. When first introduced by its European inventors, the technology that caused projectiles to spin caused such a dramatic improvement in range and accuracy that the Catholic Church temporarily banned it as the work of the devil. Go figure...
Even arrows have the feathers on the back at a slight angle so the arrow spins as it moves forwards.
Aerodynamics becomes quite the black art when fluid flow (in this case, air) reaches the magic "Reynold's number." Ahh, the power of math!
The camera work in baseball these days is outstanding. If Wakefield pitches again, watch the slow motion. Watch the seams on the ball. A knucleballer is "on" (as Wakefield was last night) when the ball takes no more than half to three quarters of a complete rotation from pitcher to catcher. When the batter "reads the seams" and sees this, he knows he's in for a very bad evening.
