In vehicle steering systems a clock spring or clockspring is a spiral-wound special rotary electrical connector which allows a vehicle's steering wheel to turn while still making an electrical connection between the steering wheel airbag and/or the vehicle's horn and other devices and the vehicle's electrical systems.rom Wikipedia, the free encyclopedia. Clocksprings generally consist of a flat multicore cable wound in a spiral shape similar to a clock spring, hence the name, but the name is also given to devices fulfilling the same purpose but which use spring-loaded brushes contacting concentric slip rings.
The notion of the existence of a so-called molecular clock was first attributed to Emile Zuckerkandl and Linus Pauling who, in 1962, noticed that the number of amino acid differences in hemoglobin between different lineages changes roughly linearly with time, as estimated from fossil evidence.he molecular clock alone can only say that one time period is twice as long as another: it cannot assign concrete dates. To achieve this, the molecular clock must first be calibrated against independent evidence about dates, such as the fossil record.
