Mars was once similar to Earth, but today there are no rivers, no lakes, no oceans. Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science. In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.

In the heart of the Scientific Revolution, when new theories promised to explain the affairs of the universe, Britain was broke, facing a mountain of debt accumulated in war after war it could not afford. But that same Scientific Revolution - the kind of thinking that helped Isaac Newton solve the mysteries of the cosmos - would soon lead clever, if not always scrupulous, men to try to figure a way out of Britain’s financial troubles.

When we think about the origins of modern science we usually begin in Europe. We remember the great minds of Nicolaus Copernicus, Isaac Newton, Charles Darwin, and Albert Einstein. But the history of science is not, and has never been, a uniquely European endeavor. Copernicus relied on mathematical techniques that came from Arabic and Persian texts. Newton’s laws of motion used astronomical observations made in Asia and Africa. When Darwin was writing On the Origin of Species, he consulted a sixteenth-century Chinese encyclopedia.

We think of transplant surgery as one of the medical wonders of the modern world. But transplant surgery is as ancient as the pyramids, with a history more surprising than we might expect. Paul Craddock takes us on a journey - from 16th-century skin grafting to contemporary stem cell transplants - uncovering stories of operations performed by unexpected people in unexpected places.

From the city sundials of ancient Rome to the era of the smartwatch, clocks have been used throughout history to wield power, make money, govern citizens and keep control. Sometimes, also with clocks, we have fought back. In About Time, time expert David Rooney tells the story of timekeeping, and how it continues to shape our modern world. In 12 chapters, demarcated like the hours of time, we meet the greatest inventions in horological history, from medieval water clocks to monumental sundials, and from coastal time signals to satellites in Earth's orbit.

Delve into the lives, inspirations, motivations and achievements of the greatest scientists in the world and through all time. Explore the stories of more than 85 of the world's most inspirational and influential scientists with this innovative and bold book of biographies. From mathematicians to meteorologists, geologists to geneticists, each scientist is presented through a combination of stimulating words.

The Middle Ages were a time of wonder. They gave us the first universities, the first eyeglasses and the first mechanical clocks as medieval thinkers sought to understand the world around them, from the passing of the seasons to the stars in the sky. In this book, we walk the path of medieval science with a real-life guide, a 14th-century monk named John of Westwyk - inventor, astrologer, crusader - who was educated in England's grandest monastery and exiled to a clifftop priory.

Mars - bewilderingly empty, coated in red dust - is an unlikely place to pin our hopes of finding life elsewhere. And yet, right now multiple spacecraft are circling, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium and Mare Sirenum - on the brink, perhaps, of a discovery that would inspire humankind as much as any in our history. With poetic precision and grace, Sarah Stewart Johnson traces the evocative history of our explorations of Mars.

One of our most beloved scientists, a fearless free spirit, Carlo Rovelli is also a masterful storyteller. In this collection of writings, the logbook of an intelligence always on the move, he follows his curiosity and invites us on a voyage through science, literature, philosophy and politics. Written with his usual clarity and wit, these pieces, most of which were first published in Italian newspapers, range widely across time and space....

Every prime minister of independent India has guided, if not personally overseen, one prized portfolio: technology. If, in the early years, Nehru and his scientist advisors retained an iron grip on it, subsequent governments created a bureaucracy that managed everything from the country's crown jewels - its nuclear and space programs - to solar stoves and mechanized bullock carts. But a lesser-known political project began on August 15, 1947: the Indian state's undertaking to influence what the citizens thought about technology and its place in society.

When scientists discovered the first ocean beyond Earth, they had two big questions: “Is it habitable?” and “How do we get there?” To answer the first, they had to answer the second, and so began a vivacious team’s twenty-year odyssey to mount a mission to Europa, the ocean moon of Jupiter. Standing in their way: NASA, the White House, Congress, rivals in academia, and even Jupiter itself. Written with verve, humor, and uncanny empathy, The Mission is an exuberant masterclass in how a few determined cogs can change an entire machine.

Sarah Cruddas has been looking to the skies her entire life. Her childhood was spent staring at the moon and hearing stories of the space race, and she worked in a fruit factory to fund her love of the subject. Her subsequent career studying astrophysics and becoming a television host and space journalist has seen her report on space exploration and chase launches across the world. In Look Up Sarah explains why she has always been a passionate advocate for why space should matter - to everyone.

Botany was the darling and the powerhouse of the 18th century. As European ships ventured across the Atlantic, Indian and Pacific oceans, discovery bloomed. Bounties of new plants were brought back, and their arrival meant much more than improved flowerbeds - it offered a new scientific frontier that would transform Europe’s industry, medicine, eating and drinking habits, and even fashion.

This lively history traces the evolution of the idea of evolution, showing how it has changed and been changed by different societies over time. It will put 'Darwin’s Dangerous Idea' into its proper context, showing how it built on what went before and how it was developed in the 20th century, through an understanding of genetics and the biochemical basis evolution. None of this diminishes the achievement of Darwin himself, but his contribution was one link in a chain that extends back into antiquity and is still being forged today.

Ambassadors from Earth relates the story of the first unmanned space probes and planetary explorers - from the Sputnik and Explorer satellites launched in the late 1950's to the thrilling interstellar Voyager missions of the '70's - that yielded some of the most celebrated successes and spectacular failures of the space age. Jay Gallentine delivers a quirky and unforgettable look at the lives and legacy of the Americans and Soviets who conceived, built, and guided those unmanned missions to the planets and beyond.

De toute éternité, les communications à distance, les télécommunications, se sont avérées essentielles pour les humains. Selon les époques, elles ont fait appel à l'imagination ou à l'ingénierie, et toujours de manière industrieuse. Ainsi, les trompettes, les tambours, la fumée ou le langage sifflé transmettaient des messages aux populations locales bien avant l'avènement du télégraphe optique, du télex ou de la téléphonie.

Les grands drames vécus lors d'une guerre relèguent habituellement les événements moins tragiques, au second rang. Bien que ces derniers passent inaperçus durant les combats, ils ne méritent pas moins d'être connus du public à cause du sentiment de bienveillance, de compassion, d'amour et d'innombrables preuves d'humanité dont ils ont fait preuve. Ce livre audio ne s'attarde donc pas sur les protagonistes des grandes batailles.

The acrid stench of asphalt and sulfur singes the hairs of people’s nostrils, and when the blustering winds subside, the potent miasma lingers in the air. To the untrained eye, the La Brea Tar Pits seem to be nothing more than simply pools of thick, viscous black sludge...The pit’s contents have spelled the doom for a countless number of creatures both large and small, from legions of insects to mighty mastodons, mammoths, and snarling saber-toothed cats from the Pleistocene Era. La Brea Tar Pits are considered by many scientists to be among the greatest finds in modern history.

What are cryptozoological animals? They are very rare animals which might even be imaginary or fantastical. In this audiobook, we examine a group of these top cryptids which may or may not be real. The history and observations of these animals comprise each chapter and an evaluation of the evidence for their existence is provided at the end of each chapter. Are all of these sightings fantasy, or do these animals really exist? And how can they hide from most of us who have actively looked for them in the past?
