Why are physicists unable to predict particle parameters, especially masses? There is a well-functioning theory whose predictions have been excellently confirmed by experiments: the general theory of relativity. However, this theory is not complete. Quantum phenomena are missing, and any expression of energy that follows Mach's principle excludes the conservation of energy and momentum. To solve this problem, we must fundamentally use different methods than those commonly employed in physics. One successful method involves boundary value problems related to chaos. An exploratory method provides the discrete values of the particle parameters. This book is a loose collection of three previously unpublished articles. Chapter 1 explains the consequences of general relativity and how to overcome the limitations of the theory. Chapter 2 contains a detailed description of the method, while Chapter 3 explains the numerical method in detail and presents the results. This book is aimed at scientists and engineers and requires knowledge of relativity theory and tensor calculus.
