This is the remarkably funny true story of some of the brave, brilliant and often barmy men that invented diving. It is a story of explosive tempers and exploding teeth, of how to juggle live hand grenades and steer a giant rubber octopus. A series of vivid portraits reveal the eccentric exploits of these underwater pioneers. They include Guy who held a world altitude record when only sixteen, wrote a film for Humphrey Bogart, invented snorkelling and loved his wife enough to shoot her. Roy wore a backet over his head and stole a coral reef. Bill wearied of fishing with dynamite and wrestling deadly snakes, so he sealed himself in a metal coffin to dangle half a mile beneath the ocean. Cameron, testing the bouncing bomb for dam busters, made a plastic ear for a dog, a false testicle for a stallion and invented a mantrap disguised as a lavatory. He ascended from a depth of 200 feet without breathing equipment to see if his lungs would burst, then studied the effects of underwater explosions by standing closer and closer until shattered by the blast. The book also traces the evolution of underwater exploration, from spear fishermen to conversationalists, from treasure hunters to archaeologists, from photographers to philosophers. The sea is a secretive and seductive place and the author describes, with incredible humour, knowledge and historical accuracy, the magic and mystery of being beneath the waves.

THE HUGELY INFLUENTIAL INTERNATIONAL BESTSELLER

From Cass R. Sunstein and Richard H. Thaler, winner of the 2017 Nobel Prize in Economics, Nudge is the book that has changed the way we think about decision-making

Nudge is about choices - how we make them and how we can make better ones. Every day we make decisions: about the things that we buy or the meals we eat; about the investments we make or our children's health and education; even the causes that we champion or the planet itself. Unfortunately, we often choose poorly. We are all susceptible to biases that can lead us to make bad decisions. And, as Thaler and Sunstein show, no choice is ever presented to us in a neutral way. By knowing how people think, we can make it easier for them to choose what is best for them, their families and society. Using dozens of eye-opening examples and original research, the authors demonstrate how to nudge us in the right directions, without restricting our freedom of choice.

Tracy wasn't surprised that her dad disapproved of Kev, with his hair in spikes, his Dayglo socks and all the rest of his punk gear. But she liked the way he looked and enjoyed going round with him. Besides, she was determined to have a good time before she had to get some boring job and settle down, like her sister Mary.
That was why the trip to Holland seemed such a great idea. Of course it was Kev who suggested it, and Tracy knew that her parents would never let her go off with Kev, just the two of them. On the other hand, if there was a whole bunch of them going, including her friend Karen and some of the others from school, Dad might - just might - say yes.
As things turned out, persuading Dad to say yes was only the beginning of her troubles. In fact so much went wrong that it was hard, afterwards, to remember the good bits, and it wasn't until the whole awful business was over that Tracy realised she should have seen what was going on all along.
