This extraordinary and very unusual book is based on discussions between the three authors, all of whom are scientists of the highest level in their fields. The topics of their discussions are of general interest – logic and its role in mathematics, the role of mathematics in the world around us, interactions between physics and mathematics, the grand unification of physics, interpretation of quantum mechanics, general relativity and cosmology, quantum gravity, string theory, etc. Their views and opinions on various questions represent varying approaches to these questions, which can often be found in the scientific community. The discussion avoids all technicalities, and is thus understandable to a general reader interested in these questions.

This small book contains a wealth of interesting ideas for further reflection and can be heartily recommended to all interested readers.
