The Trouble With String Theory. I can certainly try.
Positivism, as I understand it, is the notion that there are only three possible sources of knowledge of the universe - mathematics, logic, and direct observation. In essence, it is a radical form of empiricism. It goes further to state that to count as an item of meaningful knowledge, a statement must be verifiable and/or falsifiable. Thus, a sentence like "there is a deli located at the intersection of State and Lake streets" can be a meaningful statement of knowledge, subject to its verification or falsification (In Chicago, for instance, it is false). A sentence like "God prefers dice to bowling" is both unverifiable and unfalsifiable. Neutrino, rencontre du quatrième type. On a transmis le premier message avec des neutrinos. Schéma illustrant le principe de la communication avec des paquets de neutrinos (jaune) espacés dans le temps.
Un message en code binaire est encodé puis envoyé à l'aide d'un accélérateur de protons, produisant indirectement des neutrinos captés plus loin par un détecteur. Le signal en binaire est alors décrypté par un ordinateur. © University of Rochester.
