Interruptions to peace, order, or normal functioning; events that cause disruption or agitation.
From Middle English via Old French 'destorbance,' ultimately from Latin 'disturbare' meaning 'to throw into disorder.' The prefix 'dis-' (apart) combined with 'turbare' (to disturb, confuse).
In physics, disturbances are fundamental to wave theory - every wave is essentially a disturbance traveling through a medium. From ocean waves to sound waves to light itself, disturbances are literally how energy moves through the universe.
