The book In Search of a Theory of Everything takes readers on an adventurous journey through space and time in pursuit of a unified "theory of everything," through a rare and skillful interaction between the physical philosophies of the most significant ancient Greek thinkers and the laws of modern physics.

Developing a history and philosophy of science, physicist Demetris Nicolaides logically connects the great achievements of critical thought and unrestrained human imagination in their ambitious quest for a theory that ultimately explains all phenomena of nature through a single, immutable dominant law.

Demetris Nicolaides begins with a relatively simpler analysis of nature –such as those developed by the most important philosophers of antiquity– thereby facilitating the gradual introduction of the reader to the more complex views of modern physics, ultimately linking the two, the ancient with the modern perspective.

The thorough scientific inquiry of the universe by ancient philosophers includes ideas that harmonize with the views of modern science, enigmas of nature that still confuse us, and clever philosophical arguments that are used today to reassess competing principles of modern physics and formulate hypotheses for the open problems of nature.

The In Search of a Theory of Everything offers a new perspective, a philosophical image of modern physics, an image that has remained largely unexplored for a long time.
