John Powell, a scientist and musician, answers questions about harmony, timbre, keys, chords, loudness, musical composition, and many more in this intriguing and original guide to acoustics.

"Any reader of science fiction or viewer of Star Trek will be awake to the dream that there may be life elsewhere in our universe that isn't like life here on Earth. Maybe, like E.T., it has new letters in its genetic alphabet! Maybe it's made of silicon! Maybe it gets around on wheels! Or maybe it doesn't. In The Equations of Life, biologist Charles Cockell makes the surprising argument that the Universe constrains life, making its evolutionary outcomes...

In exhilarating and behind-the-scenes detail, Panek takes his readers on a tour of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fuelled the search, redefined science, and reinvented the universe. Science journalist Panek (The Invisible Century) offers an insider's view of the quest for what could be the ultimate revelation: the true substance of the unseen dark matter and energy that makes up some...

Explaining what we know about the Big Bang, the accelerating universe, dark energy, dark flow and dark matter, a physicist and popular science writer examines some of the theories about the nature of the universe.

A "leading theoretical physicist and YouTube star ... uses nine of the most extraordinary numbers in physics to build a picture of our current best understanding of how the universe works"--

"An accelerator physicist's fascinating journey through the experiments that uncovered the nature of matter and made the modern world. Towards the end of the nineteenth century, many scientists believed that the project of physics was nearly complete, that there was little left to explore. But as the new century dawned, scientists with the drive to deepen their understanding began looking ever more closely at the atom, and as a result of their remarkable...

"Where does great physics come from? As a young graduate student, cosmologist Stephon Alexander had a life-changing lesson in the subject. When asked by the legendary theoretical physicist Christopher Isham why he had attended graduate school, Alexander answered: "To become a better physicist." He could hardly have anticipated Isham's response: "Then stop reading those physics books." Instead, Isham said, Alexander should start listening to his dreams....
