Perhaps the most influential science book ever written, On the Origin of Species has continued to fascinate for more than a century after its initial publication. Its controversial theory that populations evolve and adapt through a process known as natural selection led to heated scientific, philosophical, and religious debate, revolutionizing every discipline in its wake. With its clear, concise, and surprisingly enjoyable prose, On the Origin of Species is both captivating and edifying.

This is the story of the greatest empire the world has ever known. Simon Baker charts the rise and fall of the world's first superpower, focusing on six momentous turning points that shaped Roman history.

From the conquest of the Mediterranean beginning in the third century BC to the destruction of the Roman Empire at the hands of barbarian invaders some seven centuries later, we discover the most critical episodes in Roman history.

When President Thomas Jefferson acquired the Louisiana Purchase - the vast, unknown lands between the Mississippi River and the Rocky Mountains, from Canada to the Gulf of Mexico - he promptly established an expedition to map America's new frontier. Meriwether Lewis and William Clark outfitted the "Corps of Discovery," and on May 14, 1804, 45 men in 3 boats set off up the Mississippi.

The Origin of Species sold out on the first day of its publication in 1859. It is the major book of the 19th century and one of the most readable and accessible of the great revolutionary works of the scientific imagination. Though, in fact, little read, most people know what it says—at least they think they do. The Origin of Species was the first mature and persuasive work to explain how species change through the process of natural selection. Upon its publication, the book began to transform attitudes about society and religion.

Tracing the extraordinary trajectory of Julius Caesar's life, Adrian Goldsworthy covers not only the great Roman emperor's accomplishments as charismatic orator, conquering general, and powerful dictator but also lesser-known chapters. Ultimately, Goldsworthy realizes the full complexity of Caesar's character and shows why his political and military leadership continues to resonate some 2,000 years later.

First published in 1871, The Descent of Man, and Selection in Relation to Sex sees Darwin apply his evolutionary theory to the human race, controversially placing apes in our family tree. The book covers a range of adjacent themes, including differences between different peoples, the dominance of women in mate choice, and the relevance of evolutionary theory to general society.

This kaleidoscopic book covers almost 3,000 years of Arab history and shines a light on the footloose Arab peoples and tribes who conquered lands and disseminated their language and culture over vast distances. Tracing this process to the origins of the Arabic language, rather than the advent of Islam, Tim Mackintosh-Smith begins his narrative more than a thousand years before Muhammad and focuses on how Arabic, both spoken and written, has functioned as a vital source of shared cultural identity over the millennia.

Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behavior of matter in a curved spacetime. The second is quantum mechanics. This theory describes the properties and behavior of matter and radiation at their smallest scales.

The Arsenal of Democracy tells the incredible story of how Detroit answered the call, centering on Henry Ford and his tortured son Edsel, who, when asked if they could deliver 50,000 airplanes, made an outrageous claim: Ford Motor Company would erect a plant that could yield a “bomber an hour”. Critics scoffed: Ford didn’t make planes; they made simple, affordable cars. But bucking his father’s resistance, Edsel charged ahead.

The dramatic account of one of America's most celebrated - and controversial - military campaigns: the Doolittle Raid. In December 1941, as American forces tallied the dead at Pearl Harbor, President Franklin Roosevelt gathered with his senior military counselors to plan an ambitious counterstrike against the heart of the Japanese Empire: Tokyo.

Einstein’s Fridge tells the incredible epic story of the scientists who, over two centuries, harnessed the power of heat and ice and formulated a theory essential to comprehending our universe. “Although thermodynamics has been studied for hundreds of years…few nonscientists appreciate how its principles have shaped the modern world” (Scientific American).

Rosemary and Peter Grant and those assisting them have spend 20 years on Daphne Major, an island in the Galapagos, studying natural selection. They recognize each individual bird on the island, when there are 400 at the time of the author's visit or when there are over a thousand. They have observed about 20 generations of finches - continuously.Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself.

Alexander von Humboldt (1769-1859) was an intrepid explorer and the most famous scientist of his age. His restless life was packed with adventure and discovery, whether climbing the highest volcanoes in the world or racing through anthrax-infested Siberia. He came up with a radical vision of nature, that it was a complex and interconnected global force and did not exist for man's use alone. Ironically, his ideas have become so accepted and widespread that he has been nearly forgotten.

How did the replication bomb we call "life" begin, and where in the world, or rather, in the universe, is it heading? Writing with characteristic wit and an ability to clarify complex phenomena (the New York Times described his style as "[T]he sort of science writing that makes the reader feel like a genius"), Richard Dawkins confronts this ancient mystery.

Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals?

When President Thomas Jefferson acquired the Louisiana Purchase - the vast, unknown lands between the Mississippi River and the Rocky Mountains, from Canada to the Gulf of Mexico - he promptly established an expedition to map America's new frontier.

A thrilling account, it tells of Colonel Fawcett and his mysterious disappearance in the Amazon jungle, which is now considered one of the greatest mysteries of the 20th century.

This essay by Thoreau first published in 1849, argues that individuals should not permit governments to overrule their consciences. It goes on to say that individuals have a duty to avoid allowing the government to make them the agents of injustice. The quote: "That government is best which governs least," sometimes attributed to Thomas Jefferson or Thomas Paine, actually was first found in this essay. Thoreaus' thoughts were motivated by his disgust with slavery and the Mexican-American War but they are still relevant and resonate today.

Part of John Muir's appeal to modern audiences is that he not only explored the American West and wrote about its beauties but also fought for their preservation. His successes dot the landscape and are evident in all the natural features that bear his name: forests, lakes, trails, and glaciers. Here collected are some of Muir's finest wilderness essays, ranging in subject matter from Alaska to Yellowstone, from Oregon to the High Sierra.

The legendary annihilation in 1883 of the volcano-island of Krakatoa - the name has since become a byword for a cataclysmic disaster - was followed by an immense tsunami that killed nearly 40,000 people. Beyond the purely physical horrors of an event that has only very recently been properly understood, the eruption changed the world in more ways than could possibly be imagined. Dust swirled round die planet for years, causing temperatures to plummet and sunsets to turn vivid with lurid and unsettling displays of light.
