Technically Speaking is the latest book from best-selling Scuba series author Simon Pridmore. It is a selection of themed talks telling the early history of technical diving—where it came from, how it developed, how it expanded across the world, who the important movers were and how, in the decade from 1989 to 1999, the efforts of a few determined people changed scuba diving forever.
The Japanese transport ship Montevideo Maru, which was found at 4,000m in the South China Sea off the coast of the Philippines, was sunk during WWII on 1 July 1942 by a torpedo launched by Salmon-class submarine USS Sturgeon, not knowing that the vessel was carrying prisoners of war and captured civilians.
Many people rush into deciding whether to cremate or bury a family member or friend without giving the matter much thought. Many families opt for cremation because they feel it best honors the dead. Some people favor cremation because it's easier to make arrangements for, while others think it's cheaper than burial. However, for several reasons, cremation isn't necessarily the best option for everyone.
Simon Pridmore's aim in writing this book was to examine and record where technical diving came from, how it developed, how it expanded across the world, who the important movers were and how the efforts of a few determined people changed our little field of human endeavour forever.
