Authors who have the ambition of making a topic of modern science or mathematics accessible to a broader public of laymen have to cope with two difficulties: On the one hand, they have to succeed in portraying complex, mostly quite specialized theories or trains of thought in simplified terms; on the other hand, they should be successful in making vivid the postulated impact and range of these theories or arguments. The latter is harder to fulfill in mathematics than, for example, in physics or biology — and the authors of the booklet at issue contend with this problem, as well.
