This book covers a number of scientific topics which would be of interest and some of them may even provoke controversy. Einstein's famous relativity theories are covered in some detail to provoke thinking. When his controversial relativity theories, which apparently run against common sense, were first introduced, it was at that time claimed that only five persons really understood them. Today relativity is accepted universally by the scientific community. To understand relativity is to understand nature itself, e.g., the concept of time, light, space and gravity. Other topics covered include consciousness and Covid-19, which are bound to arouse interest.

Professor Paul Mason is the author of numerous books and research articles.
