Showing the telescopic principle, an object collapsed (above) and extended (below), providing more reach. Telescoping in mechanics describes the movement of one part sliding out from another, lengthening an object (such as a telescope or the lift arm of an aerial work platform) from its rest state. [1]
Although the self-cleaning phenomenon of the lotus was possibly known in Asia long before (reference to the lotus effect is found in the Bhagavad Gita [25]), its mechanism was explained only in the early 1970s after the introduction of the scanning electron microscope. [4] [16] Studies were performed with leaves of Tropaeolum and lotus (Nelumbo ...
