Sidebar on the Lenard-Jones Potential Function

In expessing the derivative of the potential function, a "V" is used to represent
potential, instead of the "U" used in the original function.

1st paragraph, last line

You mention the possibilities for massively multiplayer online role-playing game (MMORG), but this is written from a 2004 perspective (copyright, 2004). In your next version, you might update this note with examples (MMORG has gotten very big since 2004).

The two paragraphs below the "Thirsty" header say the same things twice in some different wording. They
ought to be s9780596005559d just once, in one paragraph.

procedure "FuzzyTriangle" 4th line

double FuzzyTriangle(double value, double x0, double x1, double x2)
{
double result = 0;
double x = value;

Error-> if(x <= x0) --> if((x <= x0) || (x >= x2))
result = 0;
else if(x == x1)
result = 1;
else if((x>x0) && (x<x1))
result = (x/(x1-x0))-(x0/(x1-x0));
else
result = (-x/(x2-x1))+(x2/(x2-x1));

return result;
}

Omission of the second check .|| (x >= x2). results in erratic behavior with values
larger then x2 (produces negative values)

m_Left value is -2.2 and not 0.0

mLeft = FuzzyTrapezoid( 33, -40, -25, -15, 0 )

I have the result -2.2

In Figure A-3, The "Z" axs has magically shifted. Look cross-eyed at Figure A-3, and you will see that the "Z" axis has been replaced with "-V".
