Neutral buoyancy diver maintains neutral buoyancy by continuous correction, usually by controlled breathing, as neutral buoyancy is an unstable condition for a compressible object in a liquid. The mathematician Archimedes discovered much of how buoyancy works more than 2000 years ago. In his research, Archimedes discovered that an object is buoyed up by a force equal to the weight of the water displaced by the object. In other words, an inflatable boat that displaces 100 pounds (45 kilograms) of water is buoyed up by that same weight of support. An object that floats in the water is known as being "positively" buoyant.
According to Spike Milligan Bruce. "Robin Hood According to Spike Milligan" is a 1998 parody novel. Unlike other books in the series, Milligan did not parody any particular book about Robin Hood (although the majority of material parodies "The Adventures of Robin Hood" by Roger Lancelyn Green), but the whole legend of Robin Hood and the figures involved. The book portrays Robin Hood as short-tempered, Friar Tuck as a drunkard, and various other figures of the Robin Hood legend in bizarre yet humorous situations. "Treasure Island According to Spike Milligan" is a comic novel spoof of "Treasure Island" by Robert Louis Stevenson. Published in
