Devised in India in the 7th and 8th centuries and brought to North Africa by Muslim traders, the Hindu-Arabic system helped transform the West into the dominant force in science, technology, and commerce, leaving behind Muslim cultures which had long known it but had failed to see its potential.The young Italian, Leonardo of Pisa (better known today as Fibonacci), had learned the Hindu number system when he traveled to North Africa with his father, a customs agent. The book he created was Liber abbaci, the "Book of Calculation," and the revolution that followed its publication was enormous. Arithmetic made it possible for ordinary people to buy and sell goods, convert currencies, and keep accurate records of possessions more readily than ever before. Liber abbaci's publication led directly to large-scale international commerce and the scientific revolution of the Renaissance.Yet despite the ubiquity of his discoveries, Leonardo of Pisa remains an enigma. His name is best known today in association with an exercise in Liber abbaci whose solution gives rise to a sequence of numbers--the Fibonacci sequence--used by some to predict the rise and fall of financial markets, and evident in myriad biological structures.One of the great math popularizers of our time, Keith Devlin recreates the life and enduring legacy of an overlooked genius, and in the process makes clear how central numbers and mathematics are to our daily lives.

    Indeed our ability to do so is what separates we humans from the rest of the animal world. The moment man first converted a stone to a useful tool set him on a relentless path toward greater power over his environment. But have our creative ideas always produced desirable results in line with their original good intention? Have they really served us well?BAD IDEAS? traces the fascinating history of our attempts at self-improvement but also questions their value. The dubious consequences of the development of weaponry, for example, is self-evident. But what of apparently more innocuous inventions such as farming, writing or medicine? All started off for the greater good but have since produced unforeseen fallout that continues to this day. What are their undesirable side-effects, when did they emerge and where will they take us in the future?Written against a huge historical canvas, we join Robert Winston on a thrilling journey from our earliest days to the present. We learn about the history of modern science, engineering, IT and much more. We meet the individuals who played a key role in their development, and share quirky anecdotes about their lives and brainwaves. Inspiring, unusual, and at times controversial, BAD IDEAS? assesses the past and also looks forward to the opportunities and ethical challenges of the future. In so doing it celebrates man's extraordinary capacity for achievement whilst warning us that his good intentions can sometimes end up as thoroughly bad ideas.

    CR is not a diet primarily about weight loss, although readers will lose weight. CR is about eating highly nutritious foods to extend your healthy years. Here's the concept: eat fewer calories and choose foods more carefully. This will reallocate how your metabolism uses its resources to convert food into energy; in other words, what goes in will be used more efficiently. You will feel better and function better—and the big bonus: the CR diet slows aging. CR lengthens the periods of youth and middle age and substantially reduces the risk of virtually all the diseases of aging. Brian Delaney and Lisa Walford, two longtime CR practitioners, will take you on a handheld stroll through the process, including an introduction to CR, how to do it, some of the key issues in the current dialogue, and the skinny on superfoods.

    It explains how it was a premeditated, orchestrated deception, using science to impose a political agenda. It fooled a majority including most scientists. They assumed that other scientists would not produce science for a political agenda. German Physicist and meteorologist Klaus-Eckart Puls finally decided to look for himself. Here is what he discovered. Ten years ago I simply parroted what the IPCC told us. One day I started checking the facts and data—first I started with a sense of doubt but then I became outraged when I discovered that much of what the IPCC and the media were telling us was sheer nonsense and was not even supported by any scientific facts and measurements. To this day I still feel shame that as a scientist I made presentations of their science without first checking it.…scientifically it is sheer absurdity to think we can get a nice climate by turning a CO2 adjustment knob. This book uses the same approach used in investigative journalism. It examines the Who, What, Where, When, Why, and How.

    This book will entice them into reading and learning new stuff while having fun.I created the popular trivia website RaiseYourBrain and wrote two trivia books so far. As I was new to writing for kids, my son Pavel (aged 8) helped me very much. He reads a lot and really loves learning new things every day. Pavel proudly illustrated the book and helped me to handpick and order the facts.The book contains 600+ pieces of trivia and is covering topics that kids love: cute animals and human body. The lack of explicit sexuality, foul language or gore makes it a good read for anyone in the age range 8-18 years (and their parents too ;) ).A life hack if your child is NOT an avid reader: when you are preparing his/her lunch box, slip inside a couple of those facts. You could print out three facts every day to create some lunchtime fun for your kids and provoke their intellectual curiosity.

    For it's the day that Paul, my late husband and father to my seven children, decided he'd had enough of the life he had created for us all, and took himself off to the woods on the edge of our property, and fatally slashed his neck and arms." When Vikie Shanks met Paul, he seemed to be everything a girl could ever want. Handsome, attentive, caring and musically gifted, he felt like the antidote to all the bad things that had happened in her life. Vikie had had a deeply unhappy childhood, and it had scarred her. Sexually abused by her eldest brother and dominated by a violent father, her childhood ended with the death of her mother when she was just sixteen. Unravelled is the story of Vikie's life with Paul. Of the years in which his behaviour and mental state became ever more erratic. Of his casual cruelty, his spying, his inexplicable and sudden rages. Of his growing obsession with having more and more children, and of naming them according to a precise set of rules. How, over a period of years, he all but gutted their family home, tearing down most of the internal walls and removing almost everything but basic furniture, while simultaneously creating a secret home for himself, made out of plywood, in what used to be a shed. Of his secret diaries - the tens of thousands of entries he made, documenting every minute of every day. After his death, it would be these writings that would provide such compelling evidence of what further tragedy might have happened had he not made the decision that he did that fateful morning. Because whatever was wrong with him was like a ticking bomb that even Vikie hadn't properly heard; it seemed he'd spent time planning to kill the whole family.
