Permeated by the author's delightful humor, this little book explains, with nearly no mathematics, the main conceptual issues associated with quantum mechanics:The issue of determinism. Does quantum mechanics signify the end of a deterministic word-view?The role of the human subject or of the "observer" in science. Since Copernicus, science has increasingly tended to dethrone Man from his formerly held special position in the Universe. But quantum mechanics, with its emphasis on the notion of observation, may once more have given a central role to the human subject.The issue of locality. Does quantum mechanics imply that instantaneous actions at a distance exist in Nature?In these pages the author offers a variety of views and answers - bad as well as good - to these questions. The reader will be both entertained and enlightened by Jean Bricmont's clear and incisive arguments.

A thought-provoking book for the general reader interested in science and philosophy
