Kelsey Johnson
Kelsey Johnson is an astrophysicist and professor of astronomy at the University of Virginia, known for research on star formation and founding Dark Skies, Bright Kids.
Kelvin
The kelvin is the SI base unit of thermodynamic temperature, named for physicist Lord Kelvin, with zero at absolute zero, the coldest temperature matter can reach.
Kelvin probe force microscopy
Kelvin probe force microscopy, also called Kelvin force microscopy, maps surface potential and work function variations with nanoscale resolution using a conductive atomic force microscope tip.
Kelvin wave
A Kelvin wave is a rotating-fluid wave trapped by the Coriolis effect against a coast or the equator, carrying warm water eastward across the Pacific during El Niño.
Kelvin-Helmholtz cloud
A Kelvin-Helmholtz cloud, or fluctus in the WMO Cloud Atlas, is a short-lived formation of curling, wave-like clouds caused by wind shear, and a source of clear-air turbulence.
Kelvin–Helmholtz instability
The Kelvin–Helmholtz instability, also called the Kelvin–Helmholtz wave, is a fluid instability in which velocity shear between two layers overcomes stratification or magnetic tension and rolls up into vortices.
Kemp elimination
The Kemp elimination is the base-catalyzed ring-opening of a benzisoxazole to a 2-cyanophenolate, first reported in 1973 and used as a benchmark for designed enzymes.
Kempe's universality theorem
Kempe's universality theorem, announced by Alfred Bray Kempe in the 1870s, states that any plane algebraic curve can be traced exactly by a planar linkage.
Kempner function
The Kempner function, also called the Smarandache function, gives the smallest positive integer m such that n divides m!; it was introduced by Aubrey J. Kempner in 1918.
