A mind–bending but brilliantly accessible exploration of the shifting science behind the reality of time.

What is Now? This immediate moment, what we're experiencing right now ... it bathes us like air, or gravity. Yet when we try to grasp this quality, to scrutinize it or bring it into focus, it vanishes, slipping through our fingers like a dream. And worse, according to the most trusted models of physics, Now doesn't even exist. If all this is so, then what, exactly, are we experiencing? How do we carve out time, sensation, self, and meaning from a blank, Now–less canvas?

In In Search of Now, award–winning science writer Jo Marchant attempts to answer these questions with characteristic flair and clarity, taking us on a grand tour of the latest thinking from physics, neuroscience, cosmology, and psychiatry about the fundamental essence and individual experience of time. Part personal journey, part philosophical meditation, and above all a fascinating scientific exploration, In Search of Now shows us what we can learn about time, both from the outside in—the cosmic perspective of physics—and as we experience it, from the inside out.
