In the strange and fascinating world of quantum mechanics, particles have long been sorted into just two types: fermions and ...

from known particles like quarks and the Higgs boson to hypotheticals including the fifth force and strings in 11 dimensions String theory claims to make that dream a reality. In simple terms ...

Unlike the quantum theory of electromagnetism, Quantum Chromodynamics has the property that the fundamental particles (quarks and gluons) interact more and more weakly when probed at higher and higher ...

He found it in the phrase: ‘Three quarks for Muster Mark’ (page 383), adopting this for his theory. Interestingly, he preferred to pronounce it as ‘kwork’ – for which he had his own good arguments.
