We not only have the quantum theory; we also know that the energy conservation principle can be derived from the principle of

least action but not the reverse" ("A Call for Action," Science News 139 [1], May 11, 1991).

The

least action principle involves the integration of the Lagrangian densities of the fields.

It aims to explain ideas rather than achieve technical competence, and to show how

Least Action leads into the whole of physics.

These elements are prevented from moving along their

least action paths by the presence of obstructive constraints within the system.

"The report also revealed that the governments viewed as taking the

least action in tackling slavery include North Korea, Eritrea, Equatorial Guinea and Hong Kong." Ahhh, they left out Iran between North Korea and Eritrea.

The governments taking the

least action were North Korea, Iran, Eritrea, Equatorial Guinea and Hong Kong, the report said. On the other hand, the governments taking the strongest actions against such forms of slavery were the Netherlands, the United States, Britain, Sweden and Australia.

Being a fan of the trilogy, Mockingjay was our least favorite, as it had the

least action in the series and there were a lot of extraneous details we could've lived without.

Brizard presents students, academics, and researchers with the second edition of his comprehensive introduction to Langrangian mechanics, the history of the Langrangian method, FermatEs Principle of Least Time, and the mathematical principles of several mathematical predecessors of HamiltonEs Principle of

Least Action and the Euler-Lagrange equations of motion.

When p = q = 2 and F(t, [x.sub.1], [x.sub.2]) = [F.sub.1](t, [x.sub.1]), it has been proved that problem (1.1) has at least one solution by the

least action principle and the minimax methods (see [1-8]).

This is indeed true, although the principle is better known under its more common name 'principle of

least action'.

Recently derivation of CTG equations was made based on the principle of

least action [3].
