Ripples in Spacetime is an engaging account of the international effort to complete Einstein's project, capture his elusive ripples, and launch an era of gravitational-wave astronomy that promises to explain, more vividly than ever before, our universe's structure and origin. The quest for gravitational waves involved years of risky research and many personal and professional struggles that threatened to derail one of the world's largest scientific endeavors.

There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

Despite lacking pitch, rhythm, or tone, Florence Foster Jenkins became one of America's best-known sopranos, celebrated for her unique recordings and her sell-out concert at Carnegie Hall. Born in 1868 to wealthy Pennsylvanian parents, Florence was a talented young pianist, but her life was thrown into turmoil when she eloped with Frank Jenkins, a man twice her age. The marriage proved a disaster, and, in order to survive, Florence was forced to abandon her dreams of a musical career and teach the piano.

Science is not just for scientists: if it were, it could never save us from the multiple crises we face. For science can save us, if its innovations mesh carefully into society and its applications are channeled for the common good. As Martin Rees argues in this expert and personal analysis of the scientific endeavor on which we all depend, we need to think globally, we need to think rationally and we need to think long-term, empowered by twenty-first-century technology but guided by values that science alone cannot provide.

In this captivating, insightful book, acclaimed physicists Alan Lightman and Martin Rees illuminate the life and work of numerous scientists in order to demystify the scientific process and show that scientists are concerned citizens, just like the rest of us.

Humanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes - good and bad - are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and best-selling author Martin Rees argues that humanity’s prospects depend on our taking a very different approach to planning for tomorrow.
