Of the codified laws of nature, only one inscribes a direction to time: the dreaded second law of thermodynamics, which declares that the disorder of a closed system tends to increase as time passes. New shoes eventually scuff, our bodies weaken and die. Yet our senses tell us that miraculous order constantly emerges, too: children grow and learn; spontaneous patterns manifest in murmurations of starlings. Can it be true that the laws of our universe mandate only dissolution?

Con questo audiolibro breve, ma profondo e documentato, Jim Al-Khalili - fisico, divulgatore e autore di veri bestseller - espone l'intera concezione del mondo secondo la fisica attuale. Per farlo, parte dalle basi, dalle fondamenta stesse della trama di cui è fatta la realtà, chiarendo nel dettaglio, per iniziare, i concetti di spazio, tempo, energia e materia. Preparato così il palcoscenico del mondo, alzato il sipario sul racconto, l'autore espone i tre pilastri su cui poggia la fisica moderna: la relatività, la meccanica quantistica e la termodinamica.

En réponse au romantisme, poètes et écrivains du second XIXe siècle portent sur le monde réel un regard sensible mais désenchanté. Dès lors, tous les sujets sont possibles, aussi bien le beau que le laid. Baudelaire, Flaubert, Zola et bien d'autres, s'affi rment ainsi comme des écrivains modernes et opèrent un profond renouvellement de la création littéraire.

From miniature donkeys to enormous draft horses, from regal Arabian stallions to sassy Shetland ponies, horses and other equines bring us delight and comfort whenever we encounter them. Even more so, perhaps, when humans and horses are brought together through a rescue. Whether someone has started a rescue ranch on purpose or circumstances align to match up the right horse with the right person, stories of second chances warm our hearts and restore our hope.

When leading Princeton physicist Paul Steinhardt began working in the 1980s, scientists thought they knew all the conceivable forms of matter. The Second Kind of Impossible is the story of Steinhardt’s 35-year-long quest to challenge conventional wisdom. It begins with a curious geometric pattern that inspires two theoretical physicists to propose a radically new type of matter - one that raises the possibility of new materials with never-before-seen properties but that violates laws set in stone for centuries.

From launchpad explosions to a pernicious cricket infestation to the demanding management style of Musk himself, the rise of SpaceX was beset with challenges and far from inevitable. Find out how the startup beat the odds and flew high enough to outpace their rivals... and where they're going next.

Malcolm Gladwell, author of New York Times best sellers including Talking to Strangers and host of the podcast Revisionist History, uses original interviews, archival footage, and his trademark insight to weave together the stories of a Dutch genius and his homemade computer, a band of brothers in Central Alabama, a British psychopath, and pyromaniacal chemists at Harvard. As listeners hear these stories unfurl, Gladwell examines one of the greatest moral challenges in modern American history.

In this Very Short Introduction, Paul Klenerman describes the immune system, and how it works in health and disease. He considers how the immune system evolved, the basic rules that govern its behavior, and the major health threats where it is important. Paul Klenerman also explains how things can go wrong when there is too little or too much immunity. The book also addresses what we learned about the immune system from the COVID-19 pandemic and how that has influenced thinking about future pandemics.

How does Einstein’s description of space and time compare with Doctor Who? Can James Bond really escape from an armor-plated railroad car by cutting through the floor with a laser concealed in a wristwatch? What would it take to create a fully intelligent android, such as Star Trek’s Commander Data? Exploring Science Through Science Fiction addresses these and other intriguing questions, using science fiction as a springboard for discussing fundamental science concepts and cutting-edge science research.

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

Every applicable government agency and almost all mainstream media outlets claim that chemtrails are merely a "conspiracy theory". They say that the lines in the sky are harmless condensation trails and that jet aircrafts have always produced emissions that can linger in the sky for hours as they spread out and form a hazy cloud-cover. They say that anybody who asserts that aircraft are routinely spraying us with toxic materials is crazy. If this is so, then why are we consistently seeing anomalously high levels of toxins in rainwater samples as well as in ambient air samples?

Rachel Anne Ridge was at the end of her rope. The economy had crashed, taking her formerly thriving business along with it. She had been a successful artist, doing work she loved, but now she felt like a failure. How would her family pay their bills? What would the future hold? If only God would somehow let them know that everything was going to be all right... and then Flash the donkey showed up.

Long before the U.S. government began conducting secret radiation and germ-warfare experiments, and long before the Tuskegee syphilis experiments, medical professionals had introduced—and hotly debated the ethics of—the use of human subjects in medical experiments. In Subjected to Science, Susan Lederer provides the first full-length history of biomedical research with human subjects in the earlier period, from 1890 to 1940.

The chilling tome that launched an entire genre of books about the often gruesome but always tragic ways people have died in our national parks, this updated edition of the classic includes calamities in Yellowstone from the past sixteen years, including the infamous grizzly bear attacks in the summer of 2011 as well as a fatal hot springs accident in 2000. In these accounts, written with sensitivity as cautionary tales about what to do and what not to do in one of our wildest national parks, Whittlesey recounts deaths ranging from tragedy to folly.

In this exploration of the concept of the gene, Jonathan Slack looks at the discovery, nature, and role of genes in both evolution and development. Explaining the nature of genetic variation in the human population, how hereditary factors were identified as molecules of DNA, and how certain specific mutations can lead to disease, Slack highlights how DNA variants are used to trace human ancestry and migration, and can also be used by forensic scientists to identify individuals in crime.

Marcelo Gleiser has had a passion for science and fishing since he was a boy growing up on the beaches of Rio de Janeiro. As a world-famous theoretical physicist with hundreds of scientific articles and several books of popular science to his credit, he felt it was time to once again connect with nature in less theoretical ways. After seeing a fly-fishing class on the Dartmouth College green, he decided to learn to fly-fish, a hobby, he says, that teaches humility.

America's highest military award, the Congressional Medal of Honor, was awarded to 440 deserving members of the "Greatest Generation" that served in World War II. But in 1943, before the war was even over, Allied leaders realized they needed another kind of award to recognize a different kind of World War II hero - animal heroes. Founded in 1943, the prestigious PDSA Dickin Medal is the highest award an animal can achieve for gallantry and bravery in the field of military conflict. It was given to 55 animals who served valiantly alongside the members of the Greatest Generation.
