Variational Principles, .. All physical laws can be expressed in such a global form. This form leads to the local expression of physical laws, but it is richer and more powerful. In particular, it reveals the fundamental principles that govern physical laws.

Linear uniform motion is a . relative to the observer, and not a process. It is the variation of the velocity that is a process resulting from an ex

One is the inertial mass, or the coefficient of inertia, and the other is the gravitational mass, or the coupling coefficient to the gravitational field. There is no a priori argument that can explain why this equality occ

Feynman discovered a “l(fā)east action principle” that enabled him to solve the problem by using both retarded and advanced potentials. In order to do

Finally, we present some directions for further investigation on this particular line of research, taking into account possible generalizations of this work.

Next we consider two, possibly minimally more powerful robots that can count the targets exactly.
