Bonsoir,
dans la thèse de Feynman qui vient d'être publiée (moins d'un an), on peut lire:
"Although it had initially motivated his approach to QED, Feynman found later that the quantized version of the Wheeler-Feynman theory (that is, QED without fields) could not account for the experimentally observed phenomenon known as vacuum polarization. Thus in a letter to Wheeler (on May 4, 1951) Feynman wrote: "I wish to deny the correctness of the assumption that the electrons act only on other electrons... So I think we guessed wrong in 1941. Do you agree?"
Quelqu'un pourrait-il m'expliquer en gros ce qui refroidi à ce point Feynman?
Merci!
Simon
