Wondering whether eating powdered mummies might be just the thing to cure your ills? Tempted by those vintage ads suggesting you wear radioactive underpants for virility? Ever considered drilling a hole in your head to deal with those pesky headaches? Probably not! But for thousands of years, people have done things like this—and things that make radioactive underpants seem downright sensible! In their hit podcast, Sawbones, Sydnee and Justin McElroy breakdown the weird and wonderful way we got to modern healthcare . . . and some of the terrifying detours along the way.

    Using playing cards, a newspaper, the back of an envelope, a Sudoku, some pennies and of course a pair of socks, Rob Eastaway shows how maths can demonstrate its secret beauties in even the most mundane of everyday objects. Among the many fascinating curiosities in these pages, you will discover the strange link between limericks and rabbits, an apparently 'fair' coin game where the odds are massively in your favour, why tourist boards can't agree on where the centre of Britain is, and how simple paper folding can lead to a Jurassic Park monster. With plenty of ideas you'll want to test out for yourself, this engaging and refreshing look at mathematics is for everyone.

    Pluto is entrenched in our cultural and emotional view of the cosmos, and Neil deGrasse Tyson, award-winning author and director of the Rose Center, is on a quest to discover why. He stood at the heart of the controversy over Pluto's demotion, and consequently Plutophiles have freely shared their opinions with him, including endless hate mail from third-graders. With his inimitable wit, Tyson delivers a minihistory of planets, describes the oversized characters of the people who study them, and recounts how America's favorite planet was ousted from the cosmic hub.

    "A gem…An unforgettable account of one of the great moments in the history of human thought." —Steven PinkerProbing the life and work of Kurt Gödel, Incompleteness indelibly portrays the tortured genius whose vision rocked the stability of mathematical reasoning—and brought him to the edge of madness.

    It allows one to gain information by discarding information, namely, the individuality of the observations. Stigler s second pillar, information measurement, challenges the importance of big data by noting that observations are not all equally important: the amount of information in a data set is often proportional to only the square root of the number of observations, not the absolute number. The third idea is likelihood, the calibration of inferences with the use of probability. Intercomparison is the principle that statistical comparisons do not need to be made with respect to an external standard. The fifth pillar is regression, both a paradox (tall parents on average produce shorter children; tall children on average have shorter parents) and the basis of inference, including Bayesian inference and causal reasoning. The sixth concept captures the importance of experimental design for example, by recognizing the gains to be had from a combinatorial approach with rigorous randomization. The seventh idea is the residual the notion that a complicated phenomenon can be simplified by subtracting the effect of known causes, leaving a residual phenomenon that can be explained more easily.The Seven Pillars of Statistical Wisdom presents an original, unified account of statistical science that will fascinate the interested layperson and engage the professional statistician."

    But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list.  Maxwell, an unassuming Victorian Scotsman, explained how we perceive colour. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.   Along the way, he set up one of the most enduring challenges in physics, one that has taxed the best minds ever since. ‘Maxwell’s demon’ is a tiny but thoroughly disruptive thought experiment that suggests the second law of thermodynamics, the law that governs the flow of time itself, can be broken. This is the story of a groundbreaking scientist, a great contributor to our understanding of the way the world works, and his duplicitous demon.

    And two giants at the foundations of modern science were converging, step-by-step, on the answer: Albert Einstein, an young, obscure German physicist experimenting with measuring time using telegraph networks and with the coordination of clocks at train stations; and the renowned mathematician Henri Poincaré, president of the French Bureau of Longitude, mapping time coordinates across continents. Each found that to understand the newly global world, he had to determine whether there existed a pure time in which simultaneity was absolute or whether time was relative.Esteemed historian of science Peter Galison has culled new information from rarely seen photographs, forgotten patents, and unexplored archives to tell the fascinating story of two scientists whose concrete, professional preoccupations engaged them in a silent race toward a theory that would conquer the empire of time.

    Liliana is a beautiful and educated young Jewish woman. She marries Henry and becomes a mother to Rebecca. She has a full life ahead of her in Poland, or so it seems. The time period is the beginning of World War II, when the Germans invade Poland. To protect her, Liliana and Henry entrust Rebecca to their Christian friends.

To survive, Liliana (now known as Helena) assumes the identity of a Polish aristocrat and ends up working for a German officer named Robert. In a twist of fate, Robert and Helena fall in love with each other and get married. Unknown to Liliana, Henry survives and reunites with their daughter Rebecca. He finds a way to communicate with Liliana, only to find out that she started a new life. Liliana has yet to reveal her true identity to her German husband. Filled with guilt and longing for Rebecca, she thinks of putting an end to all of the lies. Will Liliana finally overcome her fears and reunite with her daughter? Parallel Lives is based on a true story. It brings the reader on a captivating journey of the "parallel lives" of a family who was separated by war. The journey takes the reader though a myriad of human emotions, including: love, jealousy, fear, despair, and freedom.

    

    The sudden loss of both parents provided the author proof positive that life IS unfair. His personal countdown clock began ticking all the louder with both of his parents gone. The author suddenly understood the importance and the urgency of enjoying life all along the way. So what did he do with his new perspective on life? Buy a Ferrari? Run with the bulls? Start doing sit ups and wearing tight shirts in an attempt to look young again?No, he didn't. Your humble author re-prioritized his Bucket List by putting a decades long dream at the top-- riding a bicycle from one side of America to the other.Armed with a burning desire to ride a really long way on a bicycle, he mounted up and pedaled onward across the United States as a newly minted orphan. Along the way he met new people, saw new places, and discovered a hidden strength masked by his grief. He also discovered a nearly endless parade of characters that together underscored how terrific it is to be above ground and riding a bike. There is fun and adventure to be had when you’re cruising across the country, and the daily dose of random was just what the doctor ordered. "Take two wheels and call me in the morning." Since the whole thing—the bike trip, life—is all just a tad absurd in the first place, why not name your bike The Fun Mover and write a book about the stars of the show--the people met along the way?Middle-aged guy gets off couch and rides bike in the face of pending death. Adventure and hilarity ensues.Bike travel can be grueling, physically and mentally. The loss of your parents can be devastating. And getting older ain’t no picnic. But obstacles can be overcome and goals can be reached if you keep trying and just keep pedaling.
