1st of all this book is huge : slightly wider than an A4 size. Around 500 pages, hardcover and fully and colourly illustrated. National Geographic doesn't do things lightly - the colour schemes, glossy pages, and broad academical information will certainly appeal any cannoisseur or anyone remotely interested in such fields as astronomy, physical sciences, inventions, technology, mathematics, social sciences, economics, philosophy, religions, arts, architecture, films and litterature among other things! Anybody with an interest in General & Scientific knowledge, as well as anyone involved in anthropology, cultural studies and especially sociology will find the book very interesting (believe me) at a very worthy price (of £11.81 when I bought it) on amazon! Totally recommended!
