The plate is 1 ½ feet from front to point. Batter will hit the ball at least a foot in front of the front edge of the plate.

And I can give you many more examples of similar or worse uses of the term ‘science.' I snuggest that you don't believe anything called ‘science' unless you know the facts behind the conclusions and even facts can be misleading.

> > > >
> > > > what's interesting is that when someone really wants to discuss SCIENCE, everyone runs away, probably because they are not noy qualified to discuss REAL SCIENCE...an example is the book bahill & watts wrote...full of scientific & mathematical models demonstrating that a ball hit 1/2 inch below center will travel x amount farther than a ball hit mid-center...everyone is afraid to discuss it (they dismiss it but don't discuss it!)...
> > > >

Is this what you are recommending?

> The point that dictates that the path must be upward is that the ball is stuck blow the equator and travels through the center of the ball. The ball is constructed to produce the most powerful reaction when the patch of the bat would travel though the core of the ball

> This means that the bat hits the outer surface of the ball 1/4 inch below the equator and on a line that travels upward through the center of the ball. To do this the batter but put the bat below the level of the ball and swing upward.

> I don't know if you remember but I do not advocate using pro batters as models for a swing to teach young batters. I say this because I know that someone will point out the Bonds, Sosa, and others, hit the ball with a ‘glancing blow' for home runs. Consider this a preemptive strike.
> joe, i THINK i know what you mean...for a moment let's uncomplicate this thing....let's say you have a machine with an arm similar to a pinball machine and let's say that from beginning to end on a perfectly parallel path the arm strikes the dead center part of the ball....now let's say we lower the contraption 1/4 inch, and again on a parallel path the arm strikes the ball 1/4 inch bekow center..are you are saying that since the direction (target) of the arm is below the center of the ball it is therefore a glancing blow?
