The fractional quantum Hall effect (FQHE) is a physical phenomenon in which the Hall conductance of 2D electrons shows precisely quantised plateaus at fractional values of . It is a property of a collective state in which electrons bind magnetic flux lines to make new quasiparticles, and excitations have a fractional elementary charge and possibly also fractional statistics. The 1998 Nobel Prize in Physics was awarded to Robert Laughlin, Horst Störmer and Daniel Tsui for the discovery and explanation of the fractional hall effect.

“Hummingbird
stay for a fractional sharp
sweetness, and’s gone, can’t take
more than that.”
—Denise Levertov (b. 1923)
“A personality is an indefinite quantum of traits which is subject to constant flux, change, and growth from the birth of the individual in the world to his death. A character, on the other hand, is a fixed and definite quantum of traits which, though it may be interpreted with slight differences from age to age and actor to actor, is nevertheless in its essentials forever fixed.”
—Hubert C. Heffner (1901–1985)
“While there we heard the Indian fire his gun twice.... This sudden, loud, crashing noise in the still aisles of the forest, affected me like an insult to nature, or ill manners at any rate, as if you were to fire a gun in a hall or temple.”
—Henry David Thoreau (1817–1862)
“We are such docile creatures, normally, that it takes a virus to jolt us out of life’s routine. A couple of days in a fever bed are, in a sense, health-giving; the change in body temperature, the change in pulse rate, and the change of scene have a restorative effect on the system equal to the hell they raise.”
—E.B. (Elwyn Brooks)
