Named a Best Book of 2021 by the Financial Times and a Best Science Book of 2021 by The Guardian
“Rovelli is a genius and an amazing communicator.... This is the place where science comes to life.” (Neil Gaiman)
“One of the warmest, most elegant and most lucid interpreters to the laity of the dazzling enigmas of his discipline...[a] momentous book.” (John Banville, The Wall Street Journal)
A startling new look at quantum theory, from the New York Times best-selling author of Seven Brief Lessons on Physics and The Order of Time.
One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving.
Helgoland is a treeless island in the North Sea where the 23-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious.
As scientists and philosophers continue to fiercely debate the meaning of the theory, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships rather than substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for thinking about the structure of reality and even the nature of consciousness.
Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better comprehend our place in it.

Critic reviews
“This entertaining and legible guide paints the history of quantum theory and lays out its possible meanings.” (Scientific American)
“Physicist Rovelli (The Order of Time) dazzles with this look at the 'almost psychedelic experience’ of understanding quantum theory.... These are big ideas, but Rovelli easily leads readers through the knotty logic, often with lyricism.... Readers who follow along will be left in awe.” (Publishers Weekly, starred review)
“Bracing and refreshing…Rovelli is offering a new way to understand not just the world but our place in it, too.” (NPR)
“Rovelli tackles both the quantum realm and the ways it helps us make sense of the mind with refreshing clarity.” (Anil Ananthaswamy, The New York Times Book Review)

While Rovelli gestures toward quantum theory’s significance outside the world of theoretical physics, he acknowledges and, in this layperson’s opinion, seems to take pains to avoid what has been called ‘Quantum BS”. He explains quantum theory as a mind-bendingly intriguing alternative view of reality to that provided by classic physics and several thousand years of cultural tradition. Nothing more, nothing less. Heisenberg’s uncertainty principle had always seemed to me profound but basic. Now I begin to understand its radical consequences in terms of science and knowledge in general. And I finally understand the fuss about Schrödinger’s cat! The narrator is also superb.

One sentence summarizes the entire idea: "The joint properties of two objects exist only in relation to a third." When reading anything about QM, keeping this one mantra in mind clarifies the entire project.
For example, this clarifies entanglement. Specifically, the Schrodinger's Cat thought experiment plays out in a very lucid way under Relational QM. In a system consisting of a quantum trigger and a cat, said system really is in a quantum superposition WITH RESPECT TO, say, me, an external observer. This is the joint properties (state) of this system in relation to me. But said joint properties can be different in relation to another entity, namely, the cat, which is indeed not in a superposition. In other words, the superposition really is ontic, but not from every perspective. This is as opposed to such things being epistemic - merely related to our knowledge of things. Quantum interference, Shor's Algorithm leveraging superposed True-False states in quantum computing... these are all very real things, but they do not exist absolutely, only from specific vantage points - their existence is relational. This is profound and truly is the best interpretation of QM.
I also appreciate Rovelli tackling the concept of "meaning" from an informational perspective, later in the book. This is a hot topic in information theoretic circles, e.g. recent papers by Artemy Kolchinsky and David Wolpert, etc., and even popular material c.f. Donald Hoffman. Clearly, Carlo Rovelli is the vanguard of humanity's best thinking here in the 21st century, and therefore will not be fully appreciated for decades yet to come.
A final note on the audio vs physical book. The physical book includes notes which are not reproduced here, and are important in that they often give the proper name to concepts discussed in otherwise romantic language, e.g. quantum decoherence. So do read the physical book and all its notes. But, this book is so short and the ideas so efficient and profound that it deserves additional readings, and these are quite nicely served by the audio book.
