Well... is there?  Just wondering, see I have this friend...

Ask your friend what the hell we are supposed to do with the remainder. That always seemed like a useless piece of information to me.

If you're finished googling, maybe you your friend could help me check my math.

You see, I have a hypothesis regarding a terrible injury last year to a future gold glove shortstop. The theory involved is objects executing motion around a point possess a quantity called angular momentum. This is an important physical quantity because all experimental evidence indicates that angular momentum is rigorously conserved in our Universe: it can be transferred, but it cannot be created or destroyed. For the simple case of a small mass executing uniform circular motion around a much larger mass (so that we can neglect the effect of the center of mass) the amount of angular momentum takes a simple form.

As the above figure illustrates the magnitude of the angular momentum in this case is L = mvr, where L is the angular momentum, m is the mass of the small object, v is the magnitude of its velocity, and r is the separation between the objects.

Are you with me?

This formula indicates one important physical consequence of angular momentum: because the above formula can be rearranged to give v = L/(mr) and L is a constant for an isolated system, the velocity v and the separation r are inversely correlated. Thus, conservation of angular momentum demands that a decrease in the separation r be accompanied by an increase in the velocity v, and vice versa.

So what exactly does that mean?

I have come to the conclusion that Carlos Lee is a big horse and plowed Adam's poor little skinny ass down.

Adam Everett...just another victim of Newtonian physics.
The rules of distinction were thrown out with the baseball cap.  It does not lend itself to protocol.  It is found today on youth in homes, classrooms, even in fine restaurants.  Regardless of its other consequences, this is a breach against civility.  A civilized man should avoid this mania.

If he ran a little faster, he could have moved up into relativistic physics, and maybe things would have turned out differently.

Up and down the M1 in some luminous yo-yo toy
But the future has to change - and to change I've got to destroy
Oh look out Lennon here I come - land ahoy-hoy-hoy

Or maybe he should have gone smaller, and he could have been both hurt and non-hurt at the same time.
Here are just a few of the key ingredients: dynamite, pole vaulting, laughing gas, choppers - can you see how incredible this is going to be?
