The Janus Point
Summary
In a universe filled by chaos and disorder, one physicist makes the radical argument that the growth of order drives the passage of time - and shapes the destiny of the universe. Time is among the universe's greatest mysteries. Why, when most laws of physics allow for it to flow forward and backward, does it only go forward? Physicists have long appealed to the second law of thermodynamics, held to predict the increase of disorder in the universe, to explain this. In The Janus Point, physicist Julian Barbour argues that the second law has been misapplied and that the growth of order determines how we experience time. In his view, the big bang becomes the "Janus point," a moment of minimal order from which time could flow, and order increase, in two directions. The Janus Point has remarkable implications: while most physicists predict that the universe will become mired in disorder, Barbour sees the possibility that order - the stuff of life - can grow without bound. A major work of physics, The Janus Point will transform our understanding of the nature of existence.

Les Arbres, entre visible et invisible
Summary
Ce livre audio brosse un panorama dans lequel le visible et l'invisible s'entrecroisent. Il y est question des peuples de l'arbre, du secret de la longévité des arbres, du nombre d'or, d'eau "nouvelle", de marées dans les fûts et de pouls cosmique des bourgeons, de messages subtils des arbres, aujourd'hui mesurables, tels les signes avant-coureurs des tremblements de terre, et de bien d'autres choses encore : qu'est-ce que le "bois de lune" ? Que nous révèle un "électrodendrogramme" ? Comment une maison en bois, un feu de bois ou tout simplement l'air de la forêt agissent sur notre santé ? Pourquoi les arbres et les forêts ont-ils été des sources de fertilité pour l'agriculture et comment peuvent-ils le redevenir - et par là même agir contre l'effet de serre ?

El ojo desnudo
Summary
En los sótanos del museo de Ciencia e Industria de Manchester hay una caja de cristal con unas pequeñas virutas que parecen fragmentos de piel seca. Estos restos son lo que queda de los globos oculares de John Dalton, el padre de la teoría atómica y el primer científico en describir la ceguera al color. Dalton dejó encargado a su médico personal que tras su muerte le extrajera los ojos y los "desnudara" para aclarar un misterio que no pudo resolver en vida: ¿Por qué él veía el mundo de manera distinta a los demás? A partir de esta anécdota, y con la vida de Dalton como hilo conductor, El ojo desnudo reconstruye una historia de nuestro conocimiento de la visión y de la luz y nos ofrece la explicación de por qué vemos como vemos y cómo hemos alcanzado a comprender fenómenos que van mucho más allá de lo que nuestros sentidos nos permiten detectar. El periodista científico Antonio Martínez Ron intenta dar respuesta a cuestiones como qué es el color, qué es la luz y cómo hemos aprendido a mirar el universo. Un viaje desde el ojo de los primeros hombres que observaron el cielo a simple vista hasta el de aquellos que dieron la vuelta a los instrumentos para mirar dentro de nosotros mismos. Y una aventura que nos ha llevado a superar nuestras limitaciones para convertirnos en la especie que todo lo ve. Please note: This audiobook is in Spanish.

Hurricanes of the Gulf of Mexico
Summary
"The storm has entered the Gulf." For those who live or travel near the Gulf of Mexico, this ominous announcement commands attention, especially given the frequency and force of hurricane strikes in recent years. Since 2004, the shores around the Gulf of Mexico have been in the crosshairs for an increasing number of hurricanes and tropical storms, including Charley and Wilma in southwestern Florida and Ivan, Dennis, Katrina, Rita, Gustav, and Ike along the northern Gulf coast from Panama City to near Galveston. In this definitive guide, climatologists Barry D. Keim and Robert A. Muller examine the big picture of Gulf hurricanes - from the 1800s to the present and from Key West, Florida, to Mexico's Yucatan Peninsula - providing an extraordinary compilation and interpretation of the entire region's hurricane and tropical storm history. Drawing from their own research and from National Hurricane Center records, Keim and Muller examine numerous individual Gulf storms, considering each hurricane's origin, oceanic and atmospheric influences, seasonality, track, intensity, size, point of landfall, storm surge, and impact on life, property, and the environment. They describe the unique features of the Gulf that influence the development of hurricanes, such as the loop current and its eddies, and identify areas of the coastline that are more or less vulnerable because of physical environment, socioeconomic environment, or both. They point out that the increase in population along the Gulf Coast over the past century has led to a rise in hurricane damage as once sparse coastlines are now lined with residents, commerce, and industry. In addition, they assess predicted hurricane activity for coming years in light of competing climate theories as well as cyclical patterns over the past century. Keim and Muller begin their book by scrutinizing the Gulf's deadliest storm, the Galveston Hurricane of 1900, whose victims received little to no warning of its approach. They then retrace 2005's Hurricane Katrina, the most costly storm, using NHC advisories and reports. Their comparison of these two catastrophic events shows that despite 105 years of tremendous technological advances, hurricanes remain ultimately rather unpredictable and human warning, readiness, and response measures continue to be imperfect. Keim and Muller also detail other memorable Gulf storms - the Labor Day Hurricane of 1935, Audrey, Betsy, Camille, Gilbert, Andrew, Wilma, and more - and give the hurricane strike records from 1901 to 2005 at thirty locations around the Gulf. They extend the New Orleans hurricane strike record back to the middle of the nineteenth century, providing key insight into comparisons of storm activities during the two centuries. An epilogue summarizes the destructive 2008 hurricane season, including storms Dolly, Gustav, and Ike. Anecdotal observations and an informative text make Hurricanes of the Gulf of Mexico a captivating and useful volume for Gulf residents, storm trackers, or anyone fascinated by the weather.

The Saga of Pappy Gunn
Summary
A four-star general pays tribute to a remarkable man in this biography. Believing that America owes a debt to a great character, a superb aviator, and a devoted citizen that was not paid, General Kenney tells the story of Paul Irvin "Pappy" Gunn with the hope that it will help discharge some of that debt. Gunn, who was known during World War II as an expert in daredevil low-level flying and as a hero and mechanical genius, modified light and medium bombers and transformed them into attack aircraft to hit Japanese targets in New Guinea, the Philippines, and Okinawa. This could very well be the first full-length story of a member of the military to be written by a commander of such rank and renown as General Kenney.

And Then You're Dead
Summary
A gleefully gruesome look at the actual science behind the most outlandish, cartoonish, and impossible deaths you can imagine. What would happen if you took a swim outside a deep-sea submarine wearing only a swimsuit? How long could you last if you stood on the surface of the sun? How far could you actually get in digging a hole to China? Paul Doherty, senior staff scientist at San Francisco's famed Exploratorium Museum, and writer Cody Cassidy explore the real science behind these and other fantastical scenarios, offering insights into physics, astronomy, anatomy, and more along the way. Is slipping on a banana peel really as hazardous to your health as the cartoons imply? Answer: yes. Banana peels ooze a gel that turns out to be extremely slippery. Your foot and body weight provide the pressure. The gel provides the humor (and resulting head trauma). Can you die by shaking someone's hand? Answer: yes. That's because, due to atomic repulsion, you've never actually touched another person's hand. If you could, the results would be as disastrous as a medium-sized hydrogen bomb. If you were Cookie Monster, just how many cookies could you actually eat in one sitting? Answer: Most stomachs can hold up to 60 cookies, or around four liters. If you eat or drink more than that, you're approaching the point at which the cookies would break through the lesser curvature of your stomach, and then you'd better call an ambulance to Sesame Street.

Probable Impossibilities
Summary
From the acclaimed author of Einstein's Dreams, a collection of meditative essays on the possibilities - and impossibilities - of nothingness and infinity, and how our place in the cosmos falls somewhere in between. Can space be divided into smaller and smaller units, ad infinitum? Does space extend to larger and larger regions, on and on to infinity? Is consciousness reducible to the material brain and its neurons? What was the origin of life, and can biologists create life from scratch in the lab? Physicist and novelist Alan Lightman, whom the Washington Post has called "the poet laureate of science writers", explores these questions and more - from the anatomy of a smile to the capriciousness of memory to the specialness of life in the universe to what came before the big bang. Probable Impossibilities is a deeply engaged consideration of what we know of the universe, of life and the mind, and of things vastly larger and smaller than ourselves.

Rebel Star
Summary
A fascinating and comprehensive guide to the sun - our home star - and why understanding it is pivotal to our future existence here on Earth. In 1869, a great mystery was born. As astronomers observed a total solar eclipse, for the first time they saw the faint glow of the solar corona, the sun's outer atmosphere. Measurements of a previously unknown wavelength that made up this solar light sparked hot debate among scientists, but it was another 60 years before they discovered that this wavelength was in fact iron being burned at a staggering three million degrees Celsius. With the sun's surface only 6,000 degrees, this shouldn't be possible. What we now knew about the sun appeared to defy the laws of physics - and nature. But as well as being shrouded in intriguing mystery, the unpredictable nature of the sun's corona poses a serious threat to our life here on earth - the destructive potential of solar storms, caused by solar material traveling out into space at around one million miles an hour, is huge. Remaining beyond our reach until now, a new generation of ambitious solar missions are currently traveling closer to the sun than any previous spacecraft in history. As we enter this unprecedented era of heliophysics, there has never been a better time to get to grips with the workings of our home star.

A Crack in the Edge of the World
Summary
The international best-selling author of The Professor and the Madman and Krakatoa vividly brings to life the 1906 San Francisco Earthquake that leveled a city symbolic of America's relentless western expansion. Simon Winchester has also fashioned an enthralling and informative informative look at the tumultuous subterranean world that produces earthquakes, the planet's most sudden and destructive force. In the early morning hours of April 18, 1906, San Francisco and a string of towns to its north-northwest and the south-southeast were overcome by an enormous shaking that was compounded by the violent shocks of an earthquake, registering 8.25 on the Richter scale. The quake resulted from a rupture in a part of the San Andreas fault, which lies underneath the earth's surface along the northern coast of California. Lasting little more than a minute, the earthquake wrecked 490 blocks, toppled a total of 25,000 buildings, broke open gas mains, cut off electric power lines throughout the Bay area, and effectively destroyed the gold rush capital that had stood there for a half century. Perhaps more significant than the tremors and rumbling, which affected a swatch of California more than 200 miles long, were the fires that took over the city for three days, leaving chaos and horror in its wake. The human tragedy included the deaths of upwards of 700 people, with more than 250,000 left homeless. It was perhaps the worst natural disaster in the history of the United States.Simon Winchester brings his inimitable storytelling abilities - as well as his unique understanding of geology - to this extraordinary event, exploring not only what happened in northern California in 1906 but what we have learned since about the geological underpinnings that caused the earthquake in the first place. But his achievement is even greater: he positions the quake's significance along the earth's geological timeline and shows the effect it had on the rest of 20th-century California and American history. A Crack in the Edge of the World is the definitive account of the San Francisco earthquake. It is also a fascinating exploration of a legendary event that changed the way we look at the planet on which we live.

Astronomical
Summary
Does the big bang prove the existence of God? What's the universe expanding into? Is Earth the only planet which supports life? Why did the greatest astronomer in history murder his pet moose? Space is the biggest, oldest, hottest, coldest, strangest thing a human can study. It's no surprise then, that the weirdest facts in science (not to mention the weirdest scientists themselves) are found in astrophysics and cosmology. If you're looking for instructions on how to set up your grandad's telescope this book probably isn't for you. In Astronomical, Tim James takes us on a tour of the known (and unknown) universe, focusing on the most mind-boggling stuff we've come across, as well as unpacking the latest theories about what's really going on out there. Guiding us through Einstein's relativity, quantum mechanics and string theory, Astronomical delves into the baffling corners of the cosmos and tackles the biggest mysteries we face: from alien life to the zodiac, from white holes to wormholes, from quasars to quark stars. This is the science of space at its absolute strangest! From the creation of the universe out of nothing to the Large Hadron Collider and the universe's ongoing expansion, Tim explores our planetary neighbours, where it snows metal on Venus, there are underground lakes on Mars and rivers of petrol on Titan. He then looks beyond our solar system: to exoplanets which could support life, rogue planets, quark stars, quasars, neutron stars and more. Tim looks at black holes (and how to survive in one), wormholes, white holes as well as dark energy, dark matter and even a bit of string theory thrown in for good measure. He explains the search for extra-terrestrial intelligence, including the discovery of Martian fossils in the Alan Hills meteorite and the tantalising 'Wow signal' transmission earth received in 1973 - still unexplained. He also rebuts resurgent anti-science movements, including the Flat Earth Society and discusses what's really going on inside Area 51. To close, Tim finishes by looking at human achievements in space including how rockets work, how faster-than-light warp-drives (currently being investigated by NASA) work and how we plan to colonise both the moon and Mars.
