Coconut oil, or copra oil, is an edible oil extracted from the kernel or meat of mature coconuts harvested from the coconut palm (Cocos nucifera). It has various applications.
The chronometer is an instrument that accurately measures time. The first one invented was a marine chronometer, and it was created out of the necessity to have an accurate timekeeper for sea travel. John Harrison, a British clockmaker, invented this device in 1737.
In the late 1860-70s, British scientist William Thomson â later known as Lord Kelvin â developed a technique based on Fourier analysis to mathematically predict the pattern of tides for particular seaports. Never just a theoretical physicist, Thomson then designed a machine to carry out these calculations.
