He's amazing calculations with the Ritz method

Abstract
We discuss an earlier application of the Ritz variational method for strongly nonlinear problems. We clearly prove that the results derived for several extremely simple problems of supposedly physical and mathematical interest do not provide any clue on the utility of the approach.
