Phase synchronization of coupled oscillators is well known in a significant number of physical systems.
However, circadian oscillators have recently been discovered in many peripheral tissues.
Similar systems, infinite chains of linearly coupled nonlinear oscillators, are also discussed.
I taught myself how to make RC oscillators and LFOs from Practical Electronics magazine's " building blocks " articles.
