In this 24-lesson course aimed at non-scientists, noted particle physicist Dr. Don Lincoln of Fermi National Accelerator Laboratory covers more than a century of progress in physics, describing exactly how scientists reach the conclusions they do. He starts with the atom, which was long hypothesized but wasn’t definitively proven until a paper by Albert Einstein in 1905. That was just the beginning, as researchers probed ever deeper into the atom’s complex structure, leading to the weird findings of quantum mechanics.

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

At the heart of this classic, seminal book is Julian Jaynes' still-controversial thesis that human consciousness did not begin far back in animal evolution but instead is a learned process that came about only 3,000 years ago and is still developing. The implications of this revolutionary scientific paradigm extend into virtually every aspect of our psychology, our history and culture, our religion - and indeed our future.

The struggle between Rome and Carthage in the Punic Wars was arguably the greatest and most desperate conflict of antiquity. The forces involved and the casualties suffered by both sides were far greater than in any wars fought before the modern era, while the eventual outcome had far-reaching consequences for the history of the Western World, namely the ascendancy of Rome. An epic of war and battle, this is also the story of famous generals and leaders: Hannibal, Fabius Maximus, Scipio Africanus, and his grandson Scipio Aemilianus, who would finally bring down the walls of Carthage.

In the aftermath of World War II, Prussia - a centuries-old state pivotal to Europe's development - ceased to exist. In their eagerness to erase all traces of the Third Reich from the earth, the Allies believed that Prussia, the very embodiment of German militarism, had to be abolished. But as Christopher Clark reveals in this pioneering history, Prussia's legacy is far more complex.
