The Shortest History of Reality: From Plato’s Cave to the Mind-Bending Discoveries of Modern Physics―The Human Quest to Explain the World

Shortest History

by Geraint F. Lewis

An award-winning astrophysicist leads a brisk, lucid tour of the human quest to uncover reality’s fundamentals, from myth-making to mathematical precision

Since the dawn of consciousness, humans have sought to make sense of this world into which we’re each born. The Shortest History of Reality explores the shifting boundary between what we perceive and what truly exists—tracing the idea of “what’s real” from its everyday, commonsense beginnings to the mind-bending discoveries of modern physics. Along the way, we encounter the profound shifts in thought that have reshaped our view of existence—from ancient philosophy to the rise of science, Newton’s universe to the staggering complexities of the quantum realm and beyond.

Drawing from the sciences, history, and philosophy, Geraint F. Lewis tells the compelling story of how we have tried to make sense of it all. An accessible, witty romp through space, time, and life’s most complex questions, The Shortest History of Reality invites us to grapple with a cosmos far stranger than our senses suggest.

[Steve · Rating 4 out of 5]

There was a lot of ground to cover and to me, Geraint F. Lewis did it reasonably well, as I consider this book as a short history of physics. I liked some of the images and found that the writing style was conversational. However words can only go so far in explaining quantum mechanics and so there was some material that I didn’t quite get. Nonetheless, the book was informative and entertaining. Thank you to Netgalley and The Experiment for the advance reader copy.

The Shortest History of Reality is not just another potted history of physics singing the same old “Greeks started things, then Newton happened, then everything changed with Einstein, and finally quantum theory came along and it’s really weird” song. Of course, there is all of that in it. After all, not everyone is as much a glutton for this genre as I am, so a fresh reader needs some grounding. But it is a very well-told version of the form with, delightfully, enough novel anecdotes and slants to reward even the jaded popular science reader.

But The Shortest History of Reality isn't just a history of physics. Instead, it is an exploration of epistemology, recounting not just what we know and when we knew it, but how we know it. Ours is an intensely mediated reality, and it changes as not just as our tools change or our math develops, but as our philosophical thinking changes. And even this is undergirded by the sensory and cognitive frameworks our species evolved with. We are not just discovering a world "out there," but constructing it layer by layer.

It's all fascinating, heady stuff, and Lewis adroitly introduces it in shockingly few pages. A highly readable and enjoyable addition to the library.
