To whomever it was who suggested that human tennis players do know the
equations of tennis ball motion, maybe not in mathematical form, but
in terms of the neural net that is their brain, I would like to offer
the following.

The key point here is whether they know the equations *exactly*. And it
seems to me quite clear that they do not. Assuming that players know the
equations exactly then they would play perfect tennis and hence no tennis
match would ever have a result. Given that all tennis matches hav had
results one must conclude that either the players do not know the
equations exactly, or that they do know the equations but don't sense
the parameters of the ball movement perfectly (if this is the case then
one wonders how they ever managed to learn the equations exactly ...?).
Either way it suggests to me that a tennis game which involved telling the
players the exact formulas would not be much of a simulation.

Now you could argue that not all simulations are exact. And that is true.
But in this case a small amoung of work will make the simulation more exact,
that work being a game interface which captured the imprecision in tennis.
ie. the problem is not inherent its just a matter of doing a bit more thinking
on the interface rather.
