Shake (unit)

A nuclear fission reaction. The process takes about 1 shake.

A shake is an informal metric unit of time equal to 10 nanoseconds, or 10−8 seconds.[1] It was originally coined for use in nuclear physics, helping to conveniently express the timing of various events in a nuclear reaction.
