In this paper a new boundary method for problems of free vibrations of plates is presented. The method is based on mathematically modelling of the physical response of a system to external excitation over a range of frequencies. The response amplitudes are then used to determine the resonant frequencies.
The aim of this paper is to describe the development of the method of fundamental solutions (mfs) and related methods over the last three decades.

Somewhat ironically, the transcendental method outlined in the the two fundamental problems where, the theory of knowledge is related to science in much the same way as science is related to the empirical world (62), has been tacitly used--it seems--to refute popper's philosophy of science as found in the logic.
In the field of computer science, the method is called generate and test (brute force). In elementary algebra, when solving equations, it is guess and check. This approach can be seen as one of the two basic approaches to problem-solving, contrasted with an approach using insight and theory.
