In all the current highly publicized debates about creationism and its descendant "intelligent design," there is an element of the controversy that is rarely mentioned—the "evidence," the empirical truth of evolution by natural selection. Even Richard Dawkins and Stephen Jay Gould, while extolling the beauty of evolution and examining case studies, have not focused on the evidence itself. Yet the proof is vast, varied, and magnificent, drawn from many different fields of science. Scientists are observing species splitting into two and are finding more and more fossils capturing change in the past—dinosaurs that have sprouted feathers, fish that have grown limbs. Why Evolution Is True weaves together the many threads of modern work in genetics, paleontology, geology, molecular biology, and anatomy that demonstrate the "indelible stamp" of the processes first proposed by Darwin. In crisp, lucid prose accessible to a wide audience, Why Evolution Is True dispels common misunderstandings and fears about evolution and clearly confirms that this amazing process of change has been firmly established as a scientific truth.

    With it, you'll learn how to write Python programs that work with large collections of unstructured text. You'll access richly annotated datasets using a comprehensive range of linguistic data structures, and you'll understand the main algorithms for analyzing the content and structure of written communication.Packed with examples and exercises, Natural Language Processing with Python will help you: Extract information from unstructured text, either to guess the topic or identify "named entities" Analyze linguistic structure in text, including parsing and semantic analysis Access popular linguistic databases, including WordNet and treebanks Integrate techniques drawn from fields as diverse as linguistics and artificial intelligenceThis book will help you gain practical skills in natural language processing using the Python programming language and the Natural Language Toolkit (NLTK) open source library. If you're interested in developing web applications, analyzing multilingual news sources, or documenting endangered languages -- or if you're simply curious to have a programmer's perspective on how human language works -- you'll find Natural Language Processing with Python both fascinating and immensely useful.

    There is every reason to believe that, within a few weeks of its onset, the infection was universally present in the nose and throat of the people, disseminated by mouth spray given off on talking by innumerable carriers and, in addition, by the coughing and sneezing of the sick. Susceptibility was very general, though it varied greatly in degree. Among those who escaped well marked sickness there are few who could not recall having had an occluded or running nose, or a raw feeling in the throat, or a cough, or aches and pains, at some time during the period of the prevalence of the disease, these probably representing the price such persons paid for their immunization." - Dr. Bernard Fantus In many ways, it is hard for modern people living in First World countries to conceive of a pandemic sweeping around the world and killing millions of people, and it is even harder to believe that something as common as influenza could cause such widespread illness and death. Although the flu still takes hundreds of lives each year, most of those lost are very young or old or ill with something else that had already weakened them. In fact, most people contract influenza at least once, and many suffer from the flu several times in their lives and survive it with a minimum amount of medical attention. In 1918, the world was still in the throes of the Great War, the deadliest conflict in human history at that point, but while World War I would be a catastrophic war surpassed only by World War II, an unprecedented influenza outbreak that same year inflicted casualties that would make both wars pale in comparison. An illness, or more likely a collection of illnesses, Spanish influenza quickly spread across the world and may have killed upwards of 100 million people, decimating populations across developed nations and possibly wiping out as much as 5% of the world’s population. If anything, the ongoing war and the censorship maintained by the countries fighting it may have resulted in the actual toll of the outbreak being underestimated based on the way soldiers’ deaths were categorized. World War I may have distracted people about the unprecedented nature of the outbreak, but the most alarming aspect of the outbreak in 1918 was the indiscriminate nature in which the scourge attacked young and old, healthy and unhealthy, and rich and poor alike. In fact, the popular name for the outbreak was a reference to the fact that Spain’s own king was stricken with the disease. While he and President Woodrow Wilson ended up surviving it, former First Lady Rose Cleveland did not. The staggering number of fatalities, and the way in which seemingly anybody could suffer during the outbreak, taught people in the early 20th century that regardless of the tremendous strides made by technology, and no matter how stalemated the war was, nobody was safe from nature itself. Of course, it also demonstrated how much more work could be done to prevent similar occurrences. The 1918 pandemic was neither the first nor the last outbreak of the flu, but it was by far the worst, and it forever changed the face of medicine and public health care in both North America and Europe. The 1918 Spanish Flu Pandemic: The History and Legacy of the World’s Deadliest Outbreak chronicles the devastating disease and the damage it wrought across the globe.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.
