This book is one of the most creative works Duerrenmatts. He used a very striking sarcasm to the problem of science (who is responsible?) To give the best. This book is easy to read, because there is little knowledge and gives it a very deep insight into the different views of some physicists. The end of this work was designed skillfully, because it stimulates the reader to himself with the said issue to deal with. Who has missed this book to read, should make up for it necessarily, because it just belongs to general education.
