    Author Michael Pollan takes readers along for the ride as he learns first-hand about the positive aspects of psychedelic drugs, including the healing and restorative effects they can have on people suffering from depression and addiction. Readers will also hear from neuroscientists to learn exactly what is happening in the brain during a psychedelic trip. Disclaimer: This is a concise summary of the book How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression, and Transcendence and does not intend to replace the original book.

    Today, scientists are attempting to measure the entire universe and to determine its origin. Although the methods have changed, the quest to chart the horizons of space and time continues to be one of the great adventures of science.Measuring the Universe is an eloquent chronicle of the men and women– from Aristarchus to Cassini, Sir Isaac Newton to Henrietta Leavitt and Stephen Hawking–who have gradually unlocked the mysteries of "how far" and in so doing have changed our ideas about the size and nature of the universe and our place in it. Kitty Ferguson reveals their methods to have been as inventive as their results were–and are–eye-opening. Advances such as Copernicus's revolutionary insights about the arrangement of the solar system, William Herschel's meticulous creation of the first three-dimensional map of the universe, and Edwin Hubble's astonishing discovery that the universe is expanding have by turns revolutionized our concept of the universe. Connecting centuries of breakthroughs with the political and cultural events surrounding them, Ferguson makes astronomy part of the sweep of history.To measure the seemingly immeasurable, scientists have always pushed the boundaries of the imagination–today, for example, facing the paradox of an ever-expanding universe that doesn't appear to expand into anything. In Kitty Fergeson's skillfill hands, the unimaginable becomes accessible and the splendid quest something we all can share.

    One morning he misses his bus when he stops to put a strange caterpillar in a matchbox. As the bus passes he’s shocked to spot himself inside. Like Schrödinger’s Cat in the famous quantum thought experiment, the caterpillar's spawned parallel possibilities. This comic novel explores Graham’s search for a better life among the various overlapping alternatives.Another clone, Grim Dupeint, is a loathsome international arms dealer. Graham infiltrates Grim’s corporation, then embezzles cash for charity. When a furious Grim realises, Graham must act fast. And right now he's acting like fish food.Graham launches upon a new lifestyle (and sex life) as he dons the designer suits of power. But sinister figures soon see through Graham’s clothing. Now Graham’s under attack from the corporation, the police, his ex-wife’s private detective, and an infuriatingly pompous water-colourist who Graham might have been if he’d gone to art college rather than business school. To survive (and steal the artist’s wonderful woman) Graham needs to find hidden resources. By definition Dopplegraham’s equally resourceful. Bugger...Schrödinger's Caterpillar - a stupid book for brainy people!

    It expands on the foundation acquired in chemistry courses and enables students to understand the mechanisms as they come across them in your classroom or laboratory.Organic Reaction Mechanisms provides extensive coverage of various organic reaction and rearrangements with emphasis on their applications in syntheses. The authors discuss reaction pathways, such as substitutions, additions, eliminations, oxidations, reductions, aromatic substitutions, aliphatic nucleophilic substitution, and electrophilic substitutions with numerous reaction equations to show the mechanism. The text also details the various reaction intermediates, including carbocations, carbanions, free radicals, carbenes, nitrines, benzynes, arynes, ylides, and enamines.Furthermore, the reagents are surveyed throughout the text, and correlation tables are provided to aid in identifying which oxidation/reduction agents to use for oxidizing/reducing various types of compounds. The applications of organic reagents are illustrated with examples and problems at the end of each chapter, which also serve to review the mechanisms learned and topics discussed. A comprehensive discussion on organic reactions, Organic Reaction Mechanisms will benefit advanced undergraduate and graduate chemistry students in their understanding and application of organic syntheses.

    Still, they took the deadly gamble—and lost. As acclaimed "New York Times" reporter and Pulitzer Prize finalist John Branch writes in this harrowing tale of disaster and survival, "the very thing the skiers and snowboarders had sought—fresh, soft snow—instantly became the enemy." In less than a minute, Tunnel Creek turned from a playground into an icy tomb.

    In addition to fieldwork and traditional methods, paleoanthropologists and archaeologists now draw upon genetics and other cutting-edge scientific techniques. In fifty chapters, Prehistoric Investigations tells the story of the many thought-provoking discoveries that have transformed our understanding of the distant past.

    So here, Jim Al-Khalili and his crack team of experts bin the crystal ball and use cutting-edge science to get a glimpse of what's in store.From whether teleportation is really possible (spoiler: it is), to what we'll do if artificial intelligence takes over, What's Next? takes on the big questions. And along the way, it'll answer questions like: Will we find a cure to all diseases? An answer to climate change? Will bionics make us into superheroes?Touching on everything from genetics to transport, and nanotechnology to teleportation, What's Next? is a fascinating, fun and informative look at what's in store for the human race.

    

    The Christians have broken the truce and the Fifth Crusade has begun, the irate Saracens are expelling Christians and Jews from their lands, and desperate refugees are pouring into Jerusalem's port city of Acre which is expected to fall. There are coins to be earned carrying those most favoured by God to safety, meaning those with the most coins to pay for a place on one of the company's galleys. And the French governor of Acre wants to leave his young wife behind and flee with the chests of coins he collected from the city's Saracen merchants before he expelled them despite the bribes they paid him. It is a rollicking good story and a very good read.

    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.

     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...
