A New Map of All the Particles and Forces | Quanta Magazine
WEBOct 22, 2020 · This approach doesn’t offer insight into the relationships between the particles. The force-carrying particles (namely the photon, which conveys the electromagnetic force; the W and Z bosons, which convey the weak force; and the gluons, which convey the strong force) are put on the same footing as the matter particles those forces act between — quarks, electrons and their kin.

How the Physics of Resonance Shapes Reality | Quanta Magazine
WEBJan 26, 2022 · Here’s how the same effect manifests in such varied settings, from everyday life down to the smallest scales. In its simplest form, resonance occurs when an object experiences an oscillating force that’s close to one of its “natural” frequencies, at which it easily oscillates. That objects have natural frequencies “is one of the ...
