Sweeter than regular coconuts, there are several sub varieties of the king coconut-the most common being the "red dwarf" (kaha thambili, commonly referred to as gon thambili). The other variety is "ran thambili", a smaller variety containing about forty nuts in a bunch. The king coconut tree is shorter than coconut trees, and are found commonly growing wild in many areas of the country. King coconut water has been used in Ayurveda. One of the most common
Liquid-crystal display This effect is based on an electro-hydrodynamic instability forming what are now called "Williams domains" inside the liquid crystal. In 1964, George H. Heilmeier, then working at the RCA laboratories on the effect discovered by Williams achieved the switching of colors by field-induced realignment of dichroic dyes in a homeotropically oriented liquid crystal. Practical problems with this new electro-optical effect made Heilmeier continue to work on scattering effects in liquid crystals and finally the achievement of the first operational liquid-crystal display based on what he called the "dynamic scattering mode" (DSM). Application of a voltage to a DSM display switches
