"With its breezy conversational style, The Universe in Your Hand is well suited for the general reader with little to no prior knowledge of science... The reader will come away from [The Universe in Your Hand] with a deeper understanding of how modern physics has brought us closer to an ultimate understanding of reality."
- The New York Times Book Review
"If Ms. Frizzle were a physics student of Stephen Hawking, she might have written THE UNIVERSE IN YOUR HAND, a wild tour through the reaches of time and space, from the interior of a proton to the Big Bang to the rough suburbs of a black hole. It's friendly, excitable, erudite, and cosmic."
―Jordan Ellenberg, New York Times besteselling author of How Not To Be Wrong
"A useful book for readers to visualize the complex ideas of modern physics."
―Kirkus Reviews
“Entertaining and comprehensive… The deft and dazzling imagery makes difficult concepts accessible, streamlining the progression through topics and fulfilling Galfard’s promise to ‘not leave any readers behind.’… Readers looking to expand their knowledge of physics and cosmology will find everything they need here.”
―Publishers Weekly, Starred Review
"Galfard dispenses with mathematical formulas in this foray into modern physics, making a lively imagination the only portal necessary for general readers hungry for the intellectual excitement of astral and atomic exploration. In a series of mind-stretching thought experiments readers plunge into the hydrogen atom in a water molecule, there to contemplate the quantum fields that sustain all matter, then shoot out beyond supernovas to ponder the strangely opaque boundary of space-time... these probes into the universe will thrill readers but rarely perplex them... Galfard leaves exhilarated readers eager to share in the forthcoming discoveries."
―Booklist, Starred Review
"How can we ever hope to fully grasp the infinite complexities of space and time, or even the very nature of reality itself? Thankfully, Christophe Galfard shows us the way, through a well-written and thoroughly approachable journey through what we know of modern astronomy and physics. Part personal conversation, part travelogue, and part science primer for the non-scientist, The Universe in Your Hand is a delightful and highly educational read."
―Jim Bell, author of The Interstellar Age and Postcards from Mars
"The Universe in Your Hand is a masterpiece of popular science writing.”
―Shelf Awareness, Starred Review
