The baseball season is almost here. To get you up to speed, the excellent new documentary Fastball opens today in select theaters.

Fastball is all about you, guessed it, the heater, the cheese, the hummer, the hard stuff.

From the perspective of pitchers, hitters, umpires,

and scientists who talk about everything from the physics governing the trajectory of the ball,

to the physiology of the strain on the pitcher's arm, to the psychology of hurling a potentially

deadly projectile at another human being, to the neuroscience of the batter's perception and reaction. At high

speeds, the ball may appear to the hitter to rise. Of course, the ball is actually still going down

due to gravity as it approaches the plate from any pitcher throwing overhand, no matter how fast.

It's just not falling as much as the batter's brain is accustomed to from watching slower pitches.

But I did not know till I saw the movie that for some hitters facing the very hardest throwers,

the ball can completely disappear.

The idea of the ball disappearing was really fascinating to me because all these Hall of Famers were talking,
