It is a collection of 150 brain teasing math riddles and puzzles. Their purpose is to make children think and stretch the mind. They are designed to test logic, lateral thinking as well as memory and to engage the brain in seeing patterns and connections between different things and circumstances. They are laid out in three chapters which get more difficult as you go through the book, in the author’s opinion at least. The answers are at the back of the book if all else fails. These are more difficult riddles and are designed to be attempted by children from 10 years onwards, as well as participation from the rest of the family.

    Amazingly, the story unveiled in it is true.In the world of math, the Poincaré Conjecture was a holy grail. Decade after decade the theorem that informs how we understand the shape of the universe defied every effort to prove it. Now, after more than a century, an eccentric Russian recluse has found the solution to one of the seven greatest math problems of our time, earning the right to claim the first one-million-dollar Millennium math prize.George Szpiro begins his masterfully told story in 1904 when Frenchman Henri Poincaré formulated a conjecture about a seemingly simple problem. Imagine an ant crawling around on a large surface. How would it know whether the surface is a flat plane, a round sphere, or a bagel- shaped object? The ant would need to lift off into space to observe the object. How could you prove the shape was spherical without actually seeing it? Simply, this is what Poincaré sought to solve.In fact, Poincaré thought he had solved it back at the turn of the twentieth century, but soon realized his mistake. After four more years' work, he gave up. Across the generations from China to Texas, great minds stalked the solution in the wilds of higher dimensions. Among them was Grigory Perelman, a mysterious Russian who seems to have stepped out of a Dostoyevsky novel. Living in near poverty with his mother, he has refused all prizes and academic appointments, and rarely talks to anyone, including fellow mathematicians. It seemed he had lost the race in 2002, when the conjecture was widely but, again, falsely reported as solved. A year later, Perelman dropped three papers onto the Internet that not only proved the Poincaré Conjecture but enlightened the universe of higher dimensions, solving an array of even more mind-bending math with implications that will take an age to unravel. After years of review, his proof has just won him a Fields Medal--the 'Nobel of math'--awarded only once every four years. With no interest in fame, he refused to attend the ceremony, did not accept the medal, and stayed home to watch television.Perelman is a St. Petersburg hero, devoted to an ascetic life of the mind. The story of the enigma in the shape of space that he cracked is part history, part math, and a fascinating tale of the most abstract kind of creativity.

    Puzzlists need only an elementary knowledge of math and a will to resist looking up the answer before trying to solve a problem.Written in a light and witty style, Entertaining Mathematical Puzzles is a mixture of old and new riddles, grouped into sections that cover a variety of mathematical topics: money, speed, plane and solid geometry, probability, topology, tricky puzzles, and more. The probability section, for example, points out that everything we do, everything that happens around us, obeys the laws of probability; geometry puzzles test our ability to think pictorially and often, in more than one dimension; while topology, among the "youngest and rowdiest branches of modern geometry," offers a glimpse into a strange dimension where properties remain unchanged, no matter how a figure is twisted, stretched, or compressed.Clear and concise comments at the beginning of each section explain the nature and importance of the math needed to solve each puzzle. A carefully explained solution follows each problem. In many cases, all that is needed to solve a puzzle is the ability to think logically and clearly, to be "on the alert for surprising, off-beat angles...that strange hidden factor that everyone else had overlooked."Fully illustrated, this engaging collection will appeal to parents and children, amateur mathematicians, scientists, and students alike, and may, as the author writes, make the reader "want to study the subject in earnest" and explains "some of the inviting paths that wind away from the problems into lusher areas of the mathematical jungle." 65 black-and-white illustrations.

     “Crime Squad takes readers on an unforgettable ride as Mike, an innocent lad from the Yorkshire Dales, learns to grow up fast and stay alive on the mean streets of London.” Weebly “A great read… gave a great feel of policing in the 80's and 90's in London, particularly with the change in drug culture and guns.” Netgalley “Well-written and informative, giving an insight into the workings of the police force in London in 1980s. Recommended.” Wendy Rhodes - Reviewer “A rollercoaster read of life on the front line.” Sir Hugh Orde OBE QPM “An accurate and fascinating picture of police work at the sharp end.” Detective Superintendent John Jones (rtd) “Gripping from first to last.” Andy Trotter OBE QPM London 1988: PC Mike Pannett, fresh out of training school, had suspected life in the Metropolitan Police was going to be a bit different from rural North Yorkshire, but the 23-year-old had no idea by just how much. Sent south of the river to Battersea, then top of London’s crime league tables, Mike was thrown straight into the deep end – during his first drugs raid he ended up staring down the wrong end of a double-barrelled shotgun. Mike’s arrival in London coincided with the explosion in crack cocaine use. In the early 1990s, Yardies – criminal gangs from Jamaica and the USA - flooded into the capital, starting in Battersea, where they brought all manner of guns with them, along with a live-fast die-young attitude. Rivals were ruthlessly eliminated and whole neighbourhoods fell under the control of drug gangs. Mike and his police colleagues fought back with extraordinary valour and inventiveness and with the support of the local community they started to turn the tide – but then came the unthinkable crime: the murder in 1993 of PC Patrick Dunne, one of Mike’s colleagues, by Gary Nelson, aka ‘Tyson’, a criminal the national press described as ‘the most dangerous man ever to walk to the streets of Britain.’ Mike was drawn into the long and exceptionally dangerous hunt for Nelson that would go on to cost the life of another police officer. Crime Squad takes readers on an unforgettable ride as Mike, an innocent lad from the Yorkshire Dales, learns to grow up fast and stay alive on the mean streets of London.

    Groundbreaking in every way when first published, this book is a simple, straightforward, direct calculus text. It's popularity is directly due to its broad use of applications, the easy-to-understand writing style, and the wealth of examples and exercises which reinforce conceptualization of the subject matter. The author wrote this text with three objectives in mind. The first was to make the book more student-oriented by expanding discussions and providing more examples and figures to help clarify concepts. To further aid students, guidelines for solving problems were added in many sections of the text. The second objective was to stress the usefulness of calculus by means of modern applications of derivatives and integrals. The third objective, to make the text as accurate and error-free as possible, was accomplished by a careful examination of the exposition, combined with a thorough checking of each example and exercise.
