This book covers a wide variety of subjects, ranging from a New World Calendar to Einstein's Theories of Relativity. It describes interesting aspects of Astronomy, History, Philosophy and Life, using simple terms that do no require prior knowledge of these matters. Several natural phenomena are examined and many scientific aspects of our environment and of life in general, are presented. The book is full of fascinating information that effectively makes it a short course in basic science and astronomy and an imaginative study of many aspects of human nature. A short section on humour provides a relaxing variation from the seriousness of the technical subjects and the controversial nature of the human aspects.
