Drift

more googlism:

drift is a stochastic process
drift is the result of “sampling error
drift is actually nonlinear
drift is an evolutionary force that can alter populations through time
drift is sombre and mysterious; a study of winter light falling on the surface of water
drift is actually nonlinear but not as much as we thought
drift is a problem
drift is widely misunderstood
drift is obtained
drift is undesirable
drift is anecdotal and qualitative
drift is present
drift is illegal
drift is exactly what my attention did
drift is the movement of spray droplets by wind
drift is a slow misadjustment which is usually adaptively corrected by some feedback mechanism
drift is more dependent on the irregular movement of turbulent air than on gravity
drift is considered just as important as natural selection

Drift: accumulation (a snow drift)
Drift: motion (to drift away)
Drift: signification (do you catch my drift?)

Drift is an interesting idea, I think.
