&quot;..there is not much meaning to computation as a concept.&quot;<p>I kind of do agree with this.<p>So, if I want to calculate a parabola, and construct a machine to launch rocks at specific velocities and angles, then this machine is a computer, but if I just throw a rock without wantint to calculate a parabola, no computation has happened?<p>What if a kid is playing around with my rock launching machine?  Is no computation happening because the kid isn&#x27;t trying to calculate parabolas?
