Aucun Actuellement, il n'y a pas de discussions au sujet de ce livre.   ) dhenn31 | Jan 24, 2024 |  A major case is his acceptance and promotion of something called the “Master Switch of Life” which he defines as a complex set of physiological reflexes that “are triggered the second we put our faces in water.” There are diving reflexes, etc in humans but I don’t feel that Nestor is qualified to report on this topic with the assurance that he seems to feel, evidently based on his conversations with divers. (There was a Scientific American article in 1963 on the subject entitled “The Master Switch of Life” but I don’t get the feeling that scientists currently use this terminology.) He also reports a lot of intriguing but totally speculative theories about dolphin and whale communications.

The author distinguishes between those who freedive - that's diving with only the breath in your lungs - and those who "freedive" to amazing depths to establish new records. These records really are remarkable - recently a Canadian made it to 145m on one breath. However, impressive this is that's all thery do and while few have dived many are injured by the practice. The author used freediving to interact with sea life - who are amazingly receptive to humans who are not creating noise and bubbles as with scuba equipment. He's joined many researchers into diving with sperm whales for instance. He's also quite dismissive about researchers who never get into the water! His insights and observations about whales is amazing especially as to their language - he reckons the clicks are digital transmissions! This is an amazingly interesting book even if you're not into diving! Thanks Claire. ( ) martinhughharvey | Jul 1, 2019 |  )1  Stbalbach | Jan 27, 2019 | aucune critique | ajouter une critique

HTML:New York Times Book Review Editors' Choice An Amazon Best Science Book of 2014 Scientific American Recommended Read "Fascinating, informative, exhilarating." Wall Street Journal Deep is a voyage from the ocean's surface to its darkest trenches, the most mysterious places on Earth. Fascinated by the sport of freedivingin which competitors descend great depths on a single breathJames Nestor embeds with a gang of oceangoing extreme athletes and renegade researchers. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and other strange phenomena. Most illuminating of all, he learns that these abilities are reflected in our own remarkable, and often hidden, potentialincluding echolocation, directional sense, and the profound bodily changes humans undergo when underwater. Along the way, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves. "A journey well worth taking." David Epstein, New York Times Book Review "Nestor pulls us below the surface into a world far beyond imagining and opens our eyes to these unseen places." Dallas Morning News "This is popular science writing at its best." Christian Science Monitor. Aucune description trouvée dans une bibliothèque |
