This book can be cut, drawn in, folded into shapes and will even take you to the fourth dimension. So join stand-up mathematician Matt Parker on a journey through narcissistic numbers, optimal dating algorithms, at least two different kinds of infinity and more.

    Not just a collection of anecdotes but a fair, reasoned appraisal of eccentric theory, it is unique in recognizing the scientific, philosophic, and sociological-psychological implications of the wave of pseudoscientific theories which periodically besets the world.To this second revised edition of a work formerly titled In the Name of Science, Martin Gardner has added new, up-to-date material to an already impressive account of hundreds of systematized vagaries. Here you will find discussions of hollow-earth fanatics like Symmes; Velikovsky and wandering planets; Hörbiger, Bellamy, and the theory of multiple moons; Charles Fort and the Fortean Society; dowsing and the other strange methods for finding water, ores, and oil. Also covered are such topics as naturopathy, iridiagnosis, zone therapy, food fads; Wilhelm Reich and orgone sex energy; L. Ron Hubbard and Dianetics; A. Korzybski and General Semantics. A new examination of Bridey Murphy is included in this edition, along with a new section on bibliographic reference material.

    He turns out to be a bird who discusses maths with anyone who will listen. So when Mr Ruche learns of his friend's mysterious death in the rainforests of Brazil he decides that with the parrot's help he will use these books to teach Max and his twin brother and sister the mysteries and wonders of numbers and shapes.But soon it becomes clear that Mr Ruche has inherited the library for reasons other than pure enlightenment, and before he knows it the household are caught up in a race to prevent the vital theorems falling into the wrong hands.Charming, fresh, with a narrative which races along, the novel takes the reader on a delightful journey through the history of mathematics.

    In The Perfect Bet, mathematician and award-winning writer Adam Kucharski tells the astonishing story of how the experts have succeeded, revolutionizing mathematics and science in the process. The house can seem unbeatable. Kucharski shows us just why it isn't. Even better, he demonstrates how the search for the perfect bet has been crucial for the scientific pursuit of a better world.

    Then, attempting to break a Nazi code during World War II, he successfully designed and built one, thus ensuring the Allied victory. Turing became a champion of artificial intelligence, but his work was cut short. As an openly gay man at a time when homosexuality was illegal in England, he was convicted and forced to undergo a humiliating "treatment" that may have led to his suicide.With a novelist's sensitivity, David Leavitt portrays Turing in all his humanity—his eccentricities, his brilliance, his fatal candor—and elegantly explains his work and its implications.

    Offering inspiration and intellectual delight, the problems throughout the book encourage students to express their ideas in writing to explain how they conceive problems, what conjectures they make, and what conclusions they reach. Applying specific techniques and strategies, readers will acquire a solid understanding of the fundamental concepts and ideas of number theory.

    Topics include the development of counting and numbers systems, the emergence of zero, cultures that don’t have numbers, algebra, solid geometry, symmetry and beauty, perspective, riddles and problems, calculus, mathematical logic, friction force and displacement, subatomic particles, and the expansion of the universe. Great mathematical thinkers covered include Napier, Liu Hui, Aryabhata, Galileo, Newton, Russell, Einstein, Riemann, Euclid, Carl Friedrich Gauss, Charles Babbage, Montmort, Wittgenstein, and many more. The book is beautifully illustrated throughout in full color.

     A secret cargo is headed for Japan. The Japanese High Command has entrusted it to a veteran destroyer captain - the best in the Imperial Navy - and he will stop at nothing to see that it reaches its final destination... Carrier-based dive bombers could not stop it, nor could the guerilla-commandos of the Philippine Islands. Now, the submarine Wolffish is the last ditch hope of the Allied Command. Still shaken by a recent tragedy, and desperately low on fuel, torpedoes, and morale, the war-weary submarine and her eighty-man crew must pull together to track down and destroy the cargo before it reaches Japan, and changes the course of the war...

    

    She claimed the police had inserted a stick inside her… Swaranpreet realised that she had been cruelly violated; He spoke a single sentence but repeated it twice in chaste Punjabi: ‘Please give me a turban? I want nothing else…’ These are voices begging for deliverance in the aftermath of Indira Gandhi’s assassination in October-November 1984 in which 2,733 Sikhs were killed, burnt and exterminated by lumpens in the country. Nilanjan Mukhopadhyay walks us through one of the most shameful episodes of sectarian violence in post Independent India and highlights the apathy of subsequent governments towards Sikhs who paid a price for what was clearly a state-sponsored riot. Poignant, raw and most importantly, macabre, the personal histories in the book reveal how even after three decades, a community continues to battle for its identity in its own country.

     When her wagon train was 8 miles from Fort Laramie, Wyoming, a Sioux Oglalas war party, in war-paint, suddenly appeared and began to encircle their wagons, pretending to be most friendly and asking for presents. The Indians urged the emigrants on, and offered to accompany them, so that they pushed on in company for a short time, until it was saw that they were approaching a ravine where his party would be at a disadvantage, and he insisted on camping outside of it. The Indians, after some hesitation, agreed, and the travellers began to make preparations for supper, when suddenly the Indians fired a volley at them. Some of those who escaped the attack succeeded in hiding in the brushwood, but Mrs. Kelly and her adopted daughter, Mary, as well as Mrs. Larimer and her children, became the prisoners of the Indians. After the second night of capture, Larimer and her son Frank managed to escape and were later reunited with her husband at Camp Collins, Colorado Territory. Larimer wrote of her harrowing captivity and escape in her 1871 book "The Capture and Escape: Life Among the Sioux." In describing dangers encountered during their escape from the Indians, Larimer noted: "The horrors of our situation were harassing to contemplate. The wolves seemed congregated upon the highlands, and, awaking from their night’s repose, their wailing cries echoed back from the distant hills with terrific clearness. These prowling creatures abound in that country, where some species attain a great size. Even the buffalo, which does not fear them in the herd, knows his danger when overtaken alone; and the solitary bull, secreted from its hunter, succumbs before the united force of a gang of wolves." Sarah Luse Larimer (1836-1913) was born in Pennsylvania, headed west in 1859 with her husband, living for a while in Allen County, Kansas, where she operated a photographic gallery. In 1864, along with her husband and son the family set out for the mines of Idaho Territory, when their plans were disrupted by Oglalas on the warpath. John Bratt in his 1921 book "Trails of Yesterday" writes of Larimer: "At Sherman Station I became well acquainted with Mrs. Larimer and her son, who kept a general store there, bought and sold ties and cord wood, while her husband had a star route mail contract from Point of Rocks north. There was also a Mrs. Kelly living near the station. These two women and Mrs. Larimer's son had been captured by the Sioux Indians near Fort Laramie. Mrs. Larimer and her son, after two weeks' captivity in the lodge of the chief, stole away one night and though the Indians hunted them day and night, they succeeded in eluding them and got back to the fort, after suffering unmentionable cruelties. Mrs. Kelly, not so fortunate, was taken by the Indians up on the Missouri River and kept with the band over six months." In describing the moment of rescue by a passing wagon train, Larimer writes that "as we sat in this shelter, which proved to be the last, a most joyful and welcome sound greeted our ears —one in which there was no mistake—our own language, spoken by some boys who passed, driving cattle."

    

    By 1949, Godel had produced a remarkable proof: In any universe described by the Theory of Relativity, time cannot exist. Einstein endorsed this result reluctantly but he could find no way to refute it, since then, neither has anyone else. Yet cosmologists and philosophers alike have proceeded as if this discovery was never made. In A World Without Time, Palle Yourgrau sets out to restore Godel to his rightful place in history, telling the story of two magnificent minds put on the shelf by the scientific fashions of their day, and attempts to rescue the brilliant work they did together.
