Why are we sometimes impatient? Why does time seem to go by faster the older we get? Does time really exist at all or is it just a virtual brainchild? If you feel like dealing with these and similar questions, we recommend this book. The first part of its almost 300 pages deals with the history of contemporary culture - so to speak "from primeval times to the clock". The second part consists of 66 answered questions from the fields of natural and cultural sciences as well as from our everyday life. Incidentally, for many of the answers there are direct references to selected internet addresses (URLs), each of which deals with the same topic.
