MEXICO CITY (apro).-John Archibald Wheeler (Jacksonville, Florida, July 9, 1911-April 13, 2008), was once one of the unique physicists who’ve ever existed on this planet of quantum mechanics. His huge talent to care for obvious quantum mysteries has made him an writer of concepts that multiple may just describe as peculiar. As an example, one of the unexpected concepts is the truth that all electrons and positrons have the similar price and mass, with out discovering variations in those measurements. How can that be? Neatly, Wheeler got here up with an unbelievable thought.
The speculation, proposed through John Wheeler, director of Richard Feynman’s doctoral thesis, gave the impression within the spring of 1940, when Wheeler telephoned Feynman claiming to have discovered a chic rationalization of the quantum-mechanical indistinguishability of electrons. In step with Feynman: At some point, Professor Wheeler known as me at Princeton Doctoral Institute and mentioned, “Feynman, I do know why all electrons have the similar price and the similar mass.” “As a result of?”. “As a result of they’re the entire identical electron!” (Richard P. Feynman (December 11, 1965). “The Construction of the Area-Time View of Quantum Electrodynamics (Nobel Lecture).” NobelPrize.org (in American English). Nobel Basis. Accessed November 1, 2020 ). This concept was once later popularized because of his acceptance speech for the 1965 Nobel Prize in Physics.
If quantum mechanics is obscure, this concept of Wheeler’s sounds extraordinary to mention the least. Feynman used to mention, “When you assume you know quantum mechanics, you have not understood it.” Subsequently all that is very complicated, however let’s attempt to perceive what Wheeler was once considering: The speculation is in line with the sector strains drawn in space-time through each and every electron. As a substitute of never-ending such strains, Wheeler recommended that they may well be portions of a unmarried line, like an enormous tied knot, drawn through a unmarried electron. Each and every quick in time can be given through a lower thru space-time, which might intersect the sure line a lot of occasions. Each and every of those assembly issues would constitute an actual electron at that second. At the ones issues, says Wheeler, part of the strains can be directed ahead in time, whilst the opposite part would have grew to become round and headed backward. Wheeler subsequently recommended that those inverse sections will be the antiparticle of the electron, the positron.
It should be mentioned that many extra electrons were noticed than positrons, so it’s believed that electrons simply outnumber them. In step with Feynman, he posed this drawback to Wheeler, who speculated that the lacking positrons may well be hidden throughout the protons (some other out-of-this-world thought). Feynman was once stunned through Wheeler’s remark that antiparticles may well be represented as inverted universe strains, and attributes this to Wheeler, pronouncing in his Nobel speech: “I did not take the concept critically.” [de Wheeler] that each one electrons have been the similar as I took the remark that positrons may just merely be represented as electrons going from the longer term to the previous in a later phase in their international strains. I stole that!”
Feynman later proposed this interpretation of the positron as an electron going again in time in his 1949 paper, “The Idea of Positrons.” Yoichiro Nambu prolonged the appliance of this to particle-antiparticle advent and annihilation, declaring that “the eventual advent and annihilation of particle-antiparticle pairs that can happen once in a while isn’t advent or annihilation, however just a exchange of particle route.” in movement, from the previous to the longer term, or from the longer term to the previous.”
It kind of feels that quantum mechanics is past us, for the reason that interpretation of observations within the quantum international is changing into increasingly peculiar. Alternatively, the one factor that may end up or disprove an concept are experiments that may ascertain or reject a concept about it. We should be conscious of the secrets and techniques of quantum mechanics, which, in line with Dr. Fernando Magaña, from the UNAM Institute of Physics, all of this turns out like “leprechaun physics.”
