Everybody knows that mathematics is indispensable to physics--imagine where we'd be today if Einstein and Newton didn't have the math to back up their ideas. But how many people realize that physics can be used to produce many astonishing and strikingly elegant solutions in mathematics? Mark Levi shows how in this delightful book, treating readers to a host of entertaining problems and mind-bending puzzlers that will amuse and inspire their inner physicist.
Levi turns math and physics upside down, revealing how physics can simplify proofs and lead to quicker solutions and new theorems, and how physical solutions can illustrate why results are true in ways lengthy mathematical calculations never can. Did you know it's possible to derive the Pythagorean theorem by spinning a fish tank filled with water? Or that soap film holds the key to determining the cheapest container for a given volume? Or that the line of best fit for a data set can be found using a mechanical contraption made from a rod and springs? Levi demonstrates how to use physical intuition to solve these and other fascinating math problems. More than half the problems can be tackled by anyone with precalculus and basic geometry, while the more challenging problems require some calculus. This one-of-a-kind book explains physics and math concepts where needed, and includes an informative appendix of physical principles.
The Mathematical Mechanic will appeal to anyone interested in the little-known connections between mathematics and physics and how both endeavors relate to the world around us.

It's as essential to human existence as water is to a fish. Every night we surrender it gratefully, only to get it back in the morning. We recognize that we have it, but we can never be sure anyone else does. Consciousness, this unique and perplexing mental state, has been the subject of debate for philosophers and scientists for millennia. And while it is widely agreed within contemporary philosophy that consciousness is a problem whose solutions are likely to determine the fate of any number of other problems, there is no settled position on the ultimate nature of consciousness.
- What is the most promising way to study this subject?
- What are the implications that arise from the fact that we have consciousness?
- What are the ethical and moral issues raised by its presence—or its absence?
Questions like these are at the heart of Consciousness and Its Implications, 12 thought-provoking lectures delivered by distinguished philosopher and psychologist Daniel N. Robinson. Rather than merely explain away consciousness, or hide behind such convenient slogans as "it's all in your brain," Professor Robinson reviews some of the special problems that philosophers, psychologists, scientists, and doctors face when taking on such a vexing topic.
What Is Consciousness?
Much of what we do every day is done without our being directly conscious of the steps taken to complete the task: riding a bicycle, taking a walk, humming a tune. But as natural as this state is, it stands as a very serious threat to any number of core convictions and assumptions in both philosophy and science. One of the overarching goals of this intriguing course is to make clear just what about consciousness serves as such a challenge to these convictions and assumptions.
But what makes Consciousness and Its Implications so engaging is more than just the nature of the questions it poses and the issues it tackles. It's the way in which Professor Robinson, the consummate teacher and scholar, conveys this goal in four main points, each of which you explore in depth in these lectures.
- Consciousness seems to require, for its full understanding, a science not yet available.
- What distinguishes consciousness from all else is its phenomenology—that is, the act of being conscious is different from all other facts of nature.
- Conscious awareness is a power that, at times, can be so strong as to greatly affect our senses.
- The powers of consciousness vary over the course of a lifetime; as such, they can become subject to disease and defect.
Compelling Examples of Consciousness
Throughout the course, Professor Robinson brings this riveting topic vividly to life with real-world examples and striking anecdotes.
- Review the case of Deep Blue, the IBM computer that in 1997 shocked the world by defeating a human, the chess grand master Garry Kasparov. Does Deep Blue's ability to "outsmart" a human being constitute a kind of consciousness? Or is it a reflection of the human minds that created this complex computer?
- Consider the case of the sleepwalker, who moves around with purpose and mimics behaviors we see in everyday life, but can remember nothing upon awakening. How does this mental state relate to human consciousness? What would be lost if we lived our entire lives as sleepwalkers?
- Study the case of a comatose patient who lives in an unbroken sleep state but, after a miraculous recovery, recalls having heard doctors speak about her. How do we interpret this patient's ability to perceive the surrounding world while in a coma? Does the patient's experience reflect some in-between mental state we've yet to define?
- Look at the case of a child with autism who can perform complicated mental tasks but lacks the most basic human attribute: empathy. How does this inability to imagine other minds affect the child's capacity to enjoy the full experience of human consciousness?
Using compelling examples such as these, Professor Robinson weaves a riveting tale of the human condition that will change the way you think about your own mind.
Probe Life's Most Profound Philosophical Riddles
Professor Robinson also draws on the wisdom of the world's greatest thinkers—from the ancient Greeks to today's top scientists—to shed light on some of the ethical debates involved in any examination of consciousness. These include
- John Locke, whose famous "Prince and the Cobbler" hypothesis raised questions about the relationship between one's personal identity and one's body;
- Ludwig Wittgenstein, whose "Beetle in a Box" scenario holds implications for how we define consciousness both inside and outside ourselves; and
- Aristotle, who led a pointed discussion on the relationship between the physical world and what he referred to as "real being."
You also enter the lab and explore the impact of modern physics and medicine on our understanding of the self. Pondering questions ranging from the most fundamental—"Why are we here?"—to contemporary quandaries about artificial intelligence and the medical decision to prolong life, you'll gain new insights into the complexity of how great minds define consciousness.
Consciousness and Its Implications is a chance for you to view this deep and profound subject from all angles. A distinguished scholar in philosophy and neuropsychology, Professor Robinson incorporates many disciplines—psychology, physics, philosophy, medicine—to explore these abiding questions.
So embark on a challenging and wholly satisfying exploration of this unique, mysterious, and essential mental faculty. The knowledge you'll gain in this course is not only intriguing—it is crucial to understanding the nature of humanity and the social and ethical obligations that define us all.

Life's Ratchet [Audiobook]

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells—assemblies of otherwise “dead” molecules—come to life, and together constitute a living being?
In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale. The complex molecules of our cells can rightfully be called “molecular machines,” or “nanobots”; these machines, unlike any other, work autonomously to create order out of chaos. Tiny electrical motors turn electrical voltage into motion, tiny factories custom-build other molecular machines, and mechanical machines twist, untwist, separate and package strands of DNA. The cell is like a city—an unfathomable, complex collection of molecular worker bees working together to create something greater than themselves.
Life, Hoffman argues, emerges from the random motions of atoms filtered through the sophisticated structures of our evolved machinery. We are essentially giant assemblies of interacting nanoscale machines; machines more amazing than can be found in any science fiction novel. Incredibly, the molecular machines in our cells function without a mysterious “life force,” nor do they violate any natural laws. Scientists can now prove that life is not supernatural, and that it can be fully understood in the context of science.
Part history, part cutting-edge science, part philosophy, Life’s Ratchet takes us from ancient Greece to the laboratories of modern nanotechnology to tell the story of our quest for the machinery of life.

The Skeleton Crew: How Amateur Sleuths Are Solving America's Coldest Cases by Deborah Halber is a very highly recommended, fascinating anecdotal look at how amateurs are solving cold cases.
Long before the popularity of forensic crime shows like CSI, amateur sleuths were using the Internet to gather clues and connect with one another to identify the remains of unidentified corpses—tens of thousands of them—across the U.S. Science writer Halber uncovers a gritty world of web sleuths taking up cold cases of murder, suicide, and accidents, of remains unmatched to missing-persons reports. Often competing with each other, sometimes appreciated or disdained by the police, many of these sleuths develop obsessions with particular victims. Using crowd-sourcing and databases, determined sleuths have managed to identify unidentified bodies.
Halber takes the reader on visits to the morgues to witness autopsies of cadavers, some deteriorated by exposure to the outdoors and harsh conditions. She explores changes in investigative techniques and the growing use of DNA to identify remains. She draws on interviews with medical examiners, police investigators, coroners, and the web sleuths themselves for an intriguing look at an underground society of quirky people easily dismissable as wackos, except that some of them occasionally solve cases the police had long abandoned.
In Your Face: The New Science of Human Attraction [EPUB]

In our daily lives, in our memories and fantasies, our mental worlds overflow with faces. But what do we really know about this most remarkable feature of the human body? Why do we have faces at all, and brains that are good at reading them? What do our looks say – and not say – about our personalities?
And perhaps the most compelling question of all: Why are we attracted to some faces more than others? In Your Face is an engaging and authoritative tour of the science of facial beauty and face perception.
David Perrett, the pre-eminent scholar in the field, reveals and interprets the most remarkable findings and in the process demolishes many popular myths, setting the record straight on what neuroscience and evolutionary psychology are teaching us about beauty. The record is more surprising and often more unsettling than you might think.

On December 6, 1941, an unexpected attack on American territory pulled an unprepared country into a terrifying new brand of warfare. Novelist and popular historian Winston Groom vividly re-creates the story of America's first year in World War II. To the generation of Americans who lived through it, the Second World War was the defining event of the twentieth century, and the defining events of that war were played out in the year 1942.
This account covers the Allies' relentless defeats as the Axis overran most of Europe, North Africa, and the Far East. But midyear the tide began to turn. America finally went on the offensive in the Pacific, and in the west the British defeated Rommel's panzer divisions at El Alamein while the U.S. Army began to push the Germans out of North Africa. By the year's end, the smell of victory was in the air. 1942: The Year That Tried Men's Souls, told with Groom's accomplished storyteller's eye, allows us into the admirals' strategy rooms, onto the battle fronts, and into the heart of a nation at war.

A spellbinding story of love amid the devastation of the Spanish Civil War
Madrid, 1936. In a city blasted by a civil war that many fear will cross borders and engulf Europe—a conflict one writer will call “the decisive thing of the century”—six people meet and find their lives changed forever. Ernest Hemingway, his career stalled, his marriage sour, hopes that this war will give him fresh material and new romance; Martha Gellhorn, an ambitious novice journalist hungry for love and experience, thinks she will find both with Hemingway in Spain. Robert Capa and Gerda Taro, idealistic young photographers based in Paris, want to capture history in the making and are inventing modern photojournalism in the process. And Arturo Barea, chief of Madrid’s loyalist foreign press office, and Ilsa Kulcsar, his Austrian deputy, are struggling to balance truth-telling with loyalty to their sometimes compromised cause—a struggle that places both of them in peril.
Hotel Florida traces the tangled wartime destinies of these three couples against the backdrop of a critical moment in history. As Hemingway put it, “You could learn as much at the Hotel Florida in those years as you could anywhere in the world.” From the raw material of unpublished letters and diaries, official documents, and recovered reels of film, Amanda Vaill has created a narrative of love and reinvention that is, finally, a story about truth: finding it out, telling it, and living it—whatever the cost.
The Vast Left Wing Conspiracy [Audiobook]

2005 | MP3@192 kbps | 7 hrs 56 mins | 655.11MB
The Left is angry: angry at President George W. Bush, the war in Iraq, the "right-wing media", and more. And as National Review investigative writer Byron York reveals in this stunning, meticulously reported book, liberal activists have harnessed that anger to build the biggest, richest, and best organized political movement in American history.
Indeed, the Left's failure to oust President Bush in 2004 has obscured the fact that this new movement has transformed American politics. York documents the staggering scope of liberals' efforts, the record sums of money spent, the "shell game" financial maneuvers, the close coordination between "nonpartisan" groups and the Democratic Party, the revolutionary approaches to fund-raising and reaching out to voters, the pioneering use of movies and Web sites as campaign tools, and more.
The Vast Left Wing Conspiracy provides a startling behind-the-scenes look at this powerful liberal movement. York brings the reader into secret powwows at Soros' Hamptons estate, into the Chinese restaurant where MoveOn is born, to a gala event where Al Franken rants about the evils of the right wing, to fund-raisers where liberals openly mock the election laws they're ignoring, to the movie premiere where Michael Moore is feted by top-ranking Democrats, into the Washington restaurant where Democratic operatives hatch their plan, and to many other spots along the way.
One thing above all becomes clear: despite their failure to win in 2004, liberals will only keep improving the well-oiled political machine they built.

In this groundbreaking book, Joe Scarborough tells Republican Party bosses what they don’t want to hear, explains why Democrats are making matters so much worse, and then shows leaders of both parties the way forward.
The Last Best Hope draws on the forgotten genius of conservatism to offer a road map for the movement and the country. Delivering a searing indictment of the political leaders who have led us astray, Scarborough inspires conservatives to reclaim their heritage by drawing upon the strength of the movement’s rich history.
With independent thinking and straight talk, Scarborough explains:
- How Washington and Wall Street conspired to create the housing bubble that caused America’s financial meltdown
- How the “candidate of change” has not only maintained but accelerated the reckless spending policies that led us to this historic economic collapse
- How Washington’s bailout culture will cripple America’s future if left unchecked
- How Barack Obama’s stimulus plan devolved into a socialist spending spree that would make FDR and LBJ shudder
- And how conservatives need to take a closer look at Ronald Reagan’s political career before claiming his great legacy
A fearlessly argued conservative manifesto that brings American conservatism into the twenty-first century, The Last Best Hope is a must-read for all who care about the direction America is heading.
Covert Capital [EPUB]

2013 | EPUB + PDF | 7.43/4.77MB
The capital of the U.S. Empire after World War II was not a city. It was an American suburb. In this innovative and timely history, Andrew Friedman chronicles how the CIA and other national security institutions created a U.S. imperial home front in the suburbs of Northern Virginia. In this covert capital, the suburban landscape provided a cover for the workings of U.S. imperial power, which shaped domestic suburban life. The Pentagon and the CIA built two of the largest office buildings in the country there during and after the war that anchored a new imperial culture and social world.
As the U.S. expanded its power abroad by developing roads, embassies, and villages, its subjects also arrived in the covert capital as real estate agents, homeowners, builders, and landscapers who constructed spaces and living monuments that both nurtured and critiqued postwar U.S. foreign policy. Tracing the relationships among American agents and the migrants from Vietnam, El Salvador, Iran, and elsewhere who settled in the southwestern suburbs of D.C., Friedman tells the story of a place that recasts ideas about U.S. immigration, citizenship, nationalism, global interconnection, and ethical responsibility from the post-WW2 period to the present. Opening a new window onto the intertwined history of the American suburbs and U.S. foreign policy, Covert Capital will also give readers a broad interdisciplinary and often surprising understanding of how U.S. domestic and global histories intersect in many contexts and at many scales.

Blitz Kids: The Children's War Against Hitler [EPUB]

A generation grew up during the Second World War but, beyond the far-from-universal experience of evacuation, what was wartime really like for those not yet old enough to take up arms? The extent to which the war affected them and was affected by them, has largely been unexplored.
What Sean Longden uncovers in Blitz Kids is a complex picture of a generation for whom the death and destruction of the Blitz became the norm. For the large numbers of young people who saw active service despite being under-aged, the experience was perhaps even more shocking.
Longden allows his many interviewees to tell their own stories while supplying enough context to knit their disparate accounts into a compelling narrative. The characters become familiar as we follow their stories through the war and beyond.
The paradoxes are clear. Many missed crucial years of education as their schools closed, yet they were launched into a world where their skills were needed more than ever. They faced unprecedented levels of both freedom and responsibility. Debates raged about soaring rates of youthful delinquency while children barely into their teens (scouts, guides, members of the Home Guard, Army Cadets and the Auxiliary Fire Service) were busy unloading ambulances, putting out incendiary bombs, raising crops and guarding targets.
Many of those only slightly older, desperate to “do their bit”, perished on battlefields and at sea. By the end of 1939, 140 boy sailors alone, some as young as 14, had been killed in action.
The experiences Longden has painstakingly unearthed range from the ridiculous (for instance, a group of Guides planning to lure German invaders into clumps of nettles) to the truly humbling. Colin Ryder Richardson describes his experience of the sinking of SS City of Benares in September 1940. The liner was carrying 90 children to the safety of Canada when it was torpedoed by an enemy submarine. The 11-year-old helped the sailor in charge of his lifeboat to boost the morale of the freezing and terrified survivors and then to dispose of their bodies as they gradually died around him.
Stretcher bearer Bill Edwardes, 17, encountered his first casualty immediately after landing in Normandy: “A jeep driver, leaning over the steering wheel, the top of his head had gone.” Soon he was patching up seemingly endless numbers of horribly injured soldiers, reassuring many whom he knew would not actually last the day that they had a passport out of the carnage, a “Blighty wound”.
However, for all the terror and loss, many of Longden’s interviewees remained children. They played on bomb sites, collected shrapnel, went to the cinema and sometimes they incurred the wrath of their parents. Roy Bartlett recalls, at the age of 12, managing to extinguish an incendiary bomb in his garden just before it could ignite 50 gallon barrels of paraffin oil in the outhouse. His reward was a ticking off from his mother for swearing.
The detail with which he and the others relive their war, more than 65 years later, is proof of just how profoundly their experiences affected them. The stories are by turns amusing, shocking and unbearably sad and Longden has done us all a great service in allowing them to be told.
Over the Ocean [EPUB]

2014 | EPUB + MOBI | 0.97/0.43MB
The extraordinary true love story of a couple who were separated during a shameful and fascinating chapter of British history, told by the couple's daughter.
In July 1940, Erich Fischer found himself in Liverpool being herded onto a British transport ship bound for Australia, along with 2,500 other men. Conditions on board were horrific, with men locked below decks with overflowing latrines and only seawater to clean themselves. Separated from family, friends and removed from any semblance of a normal life, Erich is unsure whether he will ever see wife again.
Erica Fischer’s Over the Ocean tells the extraordinary story of her own parents and at the same time sheds light on a little-known and little-discussed chapter in British history. Fischer’s parents met in Austria in the early 1930s. Her mother, Irka, was a Polish Jew and her father, Erich, was a Viennese lapsed Catholic. Faced with growing unrest in Europe, Irka fled to the United Kingdom in 1938, her husband followed a year later. However at the outbreak of war, Erich had been arrested as an ‘enemy alien’, and having been interned was deported to the opposite side of the world. Faced with unimaginable hardships, the deportees banded together in solidarity to face their new life in Australia and Erich was, against the odds, able to make contact with Irka and their letters established a lifeline between continents.
