| p.201: John Wheeler is impressed by the fact that according to the standard Copenhagen interpretation of quantum mechanics, a physical system cannot be said to have any definite values for quantities like position or energy or momentum until these quantities are measured by some observer’s apparatus. For Wheeler, some sort of intelligent life is required in order to give meaning to quantum mechanics, Recently Wheeler has gone further and proposed that intelligent life not only must appear but must go on to pervade every part of the universe in order that every bit of information about the physical state of the universe should eventually be observed. Wheeler’s conclusions seem to me to provide a good example of the dangers of taking too seriously the doctrine of positivism, that science should concern itself only with things that can be observed. Other physicists including myself prefer another, realist, way of looking at quantum mechanics, in terms of a wave function that can describe laboratories and observers as well as atoms and molecules, governed by laws that do not materially depend on whether there are any observers or not. | |

Commentaire: Nouvel exemple des dangers de l’empirisme. Du positivisme à l’idéalisme, la pente est glissante et on n’est alors plus loin de la religion. Ajoutée par : admin |

Article très daté. Il fait une critique intéressante de l’interprétation de Copenhague du point de vue de la dialectique, mais il place trop d’espoir dans la relance par David Bohm de la piste de Louis de Broglie. Ce n’est pas dans cette direction que la physique a dépassé la complémentarité à la Bohr. Ajoutée par : admin |
