Oscillations occur not only in mechanical systems but also indynamic systemsin virtually every area of science: for example the beating of thehuman heart(for circulation),business cyclesineconomics,predator–preypopulation cycles inecology, geothermalgeysersingeology, vibration of strings inguitarand otherstring instruments, periodic firing ofnerve cellsin the brain, and the periodic swelling ofCepheid variablestars inastronomy. |
