I was reading the volume on mechanics and I think the way they determine the dependence of the action function for a free particle to be on the velocity alone is just beautiful, how they rule out any dependence of the action function on the coordinates based solely on the isotropy of space, and the same for the time coordinate.
And all of this without even making use of any generalized coordinates, or restrictions in the motion, or any calculations at all to determine the explicit form of the action function!
Any similar experiences you've had with any volume from this series? you know, one of those arguments of reason that almost take your breath.
