Book cover of Helgoland: Making Sense of the Quantum Revolution

Harry Cliff Author Of Space Oddities: The Mysterious Anomalies Challenging Our Understanding of the Universe

From my list on the universe and our cosmic origins.

Why am I passionate about this?

I’ve been fascinated by science since I was a small child. I used to try to drag my parents up to London’s Natural History Museum to gawk at dinosaurs every other Sunday and remember the delight of seeing Saturn and its rings through a telescope from our back garden. I started reading popular science books as a teenager and they were a large part of what inspired me to ultimately become a physicist. I hope the books on this list will bring a bit of awe and wonder into your life!

Harry's book list on the universe and our cosmic origins

Harry Cliff Why did Harry love this book?

I didn’t so much read this book as inhale it. Rovelli’s writing is always highly readable, and this one is no exception. The book tells the dramatic story of the origin of quantum mechanics, beginning with a holiday spent on the windswept island of Helgoland by the German physicist Werner Heisenberg in the 1920s.

Rovelli introduces the history of the core ideas of quantum mechanics with great clarity and provides an interesting new way of interpreting quantum weirdness that I found fascinating.

Quantum physics is supposed to be weird and mysterious, right? You might then get the impression that Beyond Weird will explain how quantum physics is weirder than weird. But, no! Beyond Weird is about how we can beyond the concept that quantum physics is weird. Philip Ball does an amazing job telling the story of how physicists have tried to make sense of quantum theory.

What is this book about?

"Anyone who is not shocked by quantum theory has not understood it."

Since Niels Bohr said this many years ago, quantum mechanics has only been getting more shocking. We now realize that it's not really telling us that "weird" things happen out of sight, on the tiniest level, in the atomic world: rather, everything is quantum. But if quantum mechanics is correct, what seems obvious and right in our everyday world is built on foundations that don't seem obvious or right at all-or even possible.

An exhilarating tour of the contemporary quantum landscape, Beyond Weird is a book about what…

Are you still here? Good. Because by now you are probably reading to tackle some university-level courses in quantum physics, right? Well, with your background in pop quantum physics all you need to get there is a little more abstraction. So, if you have the stomach for a bit of mathematics, Quantum Mechanics: The Theoretical Minimum by Leonard Susskind is your ticket to the big show! (Don’t say I didn’t warn you about the math, though.)

First he taught you classical mechanics. Now, physicist Leonard Susskind has teamed up with data engineer Art Friedman to present the theory and associated mathematics of the strange world of quantum mechanics.In this follow-up to the New York Times best-selling The Theoretical Minimum , Susskind and Friedman provide a lively introduction to this famously difficult field, which attempts to understand the behaviour of sub-atomic objects through mathematical abstractions. Unlike other popularizations that shy away from quantum mechanics' weirdness, Quantum Mechanics embraces the utter strangeness of quantum logic. The authors offer crystal-clear explanations of the principles of quantum states, uncertainty and…


Book cover of Seven Brief Lessons on Physics

Abi Curtis Author Of The Headland

From my list on speculative fiction with soul.

Why am I passionate about this?

I’m a Professor of Creative Writing at York St John’s University in York, UK. I’ve been published as a poet, novelist, and nonfiction writer. My list reflects perhaps some eclectic tastes, but what unites these books is a fascination with engaging with the world in a way that de-centers the human, and I have done this throughout my writing career. I love the natural world, growing plants, and watching the seasons change. I am also curious about time and memory and how we perceive these. I am drawn towards science fiction, but more the speculative end of that spectrum, where writers explore otherness and possible worlds. 

Abi's book list on speculative fiction with soul

Abi Curtis Why did Abi love this book?

I’ve always been interested in physics, but I have no talent for maths, and like lots of creative types, I find science tough. But not with the engaging voice of Italian physicist Rovelli. This blew my mind and blew the lid off of the universe.

Rovelli explains the fundamentals of physical laws beautifully but then introduces the quantum realm, where time and space are not at all what you thought they were. This isn’t unsettling to me, but it is profoundly beautiful. Time may not be linear at all, we simply have no other way of perceiving it, which means moments in time I felt were lost, are not at all if you look at them another way.

But it also reinforces the idea we must exist in the moment and savor it, as, in a sense, that’s all we have.

From my list on Albert Einstein for the non-scientist.

Why am I passionate about this?

I am the co-founder and current owner of The Manhattan Rare Book Company. I’ve been in the rare book business for 25 years, specializing in the history of science with particular emphasis on material relating to Albert Einstein. Like many people, I’ve long been drawn to Einstein, attracted by his wisdom, curiosity, personality, approachability, and general decency. 

Michael's book list on Albert Einstein for the non-scientist

Michael DiRuggiero Why did Michael love this book?

Of all the books I've read about Einstein, this one was, perhaps, the most eye-opening for me. For years, the prevailing opinion was that while Einstein was (of course) brilliant, and his special and general theories of relativity were seismically important, he was on the wrong side of history with his views on quantum theory. Stone sets the record straight: Einstein was indeed skeptical of many aspects of quantum theory (particularly with his refusal to accept quantum entanglement and inherent randomness), but his challenges to the theory were so intelligent and so piercing, that the entire scientific community had to respond to him. Stone argues convincingly that Einstein's concerns were often the driving force propelling the theory forward.

2 authors picked Einstein and the Quantum as one of their favorite books, and they share why you should read it.

What is this book about?

Einstein and the Quantum reveals for the first time the full significance of Albert Einstein's contributions to quantum theory. Einstein famously rejected quantum mechanics, observing that God does not play dice. But, in fact, he thought more about the nature of atoms, molecules, and the emission and absorption of light--the core of what we now know as quantum theory--than he did about relativity. A compelling blend of physics, biography, and the history of science, Einstein and the Quantum shares the untold story of how Einstein--not Max Planck or Niels Bohr--was the driving force behind early quantum theory. It paints a…


Book cover of Quantum: Einstein, Bohr, and the Great Debate about the Nature of Reality

Art Hobson Author Of Tales of the Quantum: Understanding Physics' Most Fundamental Theory

From my list on quantum physics and how the universe works.

Why am I passionate about this?

Since my first college course in quantum physics, I have been fascinated with this enigmatic, infinitely interesting theory. It's our most fundamental description of the universe, it's been found to be unerringly accurate, yet it's quite subtle to interpret. Even more intriguingly, "nobody really understands quantum physics" (as Richard Feynman put it). For example, the theory's central concept, the wave function, is interpreted radically differently by different physicists. I have always yearned to grasp, at least to my own satisfaction, a comprehensive understanding of this theory. Since retirement 23 years ago, I have pursued this passion nearly full-time and found some answers, leading to several technical papers and a popular book.

Art Hobson Why did Art love this book?

Given the radically distinct and often incongruent views of what quantum physics means, it is wise to glean a balanced sense of many views by studying the topic's history. Kumar's telling of the great, decades-long debate between two of the field's leading practitioners is authoritative and excitingly told. The book centers on the founding of quantum physics during the 1920s, the famous 1927 Solvay Conference on photons and electrons, and the thoughtful debate between Bohr and Einstein concerning the nature of reality. The author is a physicist, philosopher, and science writer.

'This is about gob-smacking science at the far end of reason ... Take it nice and easy and savour the experience of your mind being blown without recourse to hallucinogens' Nicholas Lezard, Guardian
For most people, quantum theory is a byword for mysterious, impenetrable science. And yet for many years it was equally baffling for scientists themselves.

In this magisterial book, Manjit Kumar gives a dramatic and superbly-written history of this fundamental scientific revolution, and the divisive debate at its core. Quantum theory looks at the very building blocks of our world, the particles and processes without which it could…

Art's book list on quantum physics and how the universe works

Art Hobson Why did Art love this book?

Guilder uses historical vignettes to describe how entanglement came to be regarded as a – or perhaps thecentral pillar of quantum physics. For example, we share a streetcar ride through Copenhagen in 1923 with Niels Bohr, Albert Einstein, and Arnold Sommerfeld. Although we don't know precisely what they discussed, Guilder indicates what they probably discussed based on quotations from letters and other evidence. Thus, the book reads like a historical novel. It centers on the distant correlations, dubbed (by Einstein and Erwin Schrodinger) "spooky action at a distance." Since 1964, physicists have shown this astonishing phenomenon, now called "non-locality," to be clearly predicted by quantum theory and fully confirmed by experiment. This development is the "rebirth" of quantum physics referred to in the title.  Guilder is a non-scientist who writes beautifully with a good grasp of physics.

What is this book about?

In The Age of Entanglement, Louisa Gilder brings to life one of the pivotal debates in twentieth century physics. In 1935, Albert Einstein famously showed that, according to the quantum theory, separated particles could act as if intimately connected–a phenomenon which he derisively described as “spooky action at a distance.” In that same year, Erwin Schrödinger christened this correlation “entanglement.” Yet its existence was mostly ignored until 1964, when the Irish physicist John Bell demonstrated just how strange this entanglement really was. Drawing on the papers, letters, and memoirs of the twentieth century’s greatest physicists, Gilder both humanizes and dramatizes…

Why am I passionate about this?

I have always been fascinated by how the world works. What gives gravity so much power? Why is it easier to lift things with levers and pulleys? Why do we have electricity inside of our own bodies?! The world is amazing. My job editing nonfiction books for kids puts me on the front lines of some of the smartest science writing out there. While I had no hand in the making of the following five picture books about physics, they are still some of my favorites because of the way they peel back the mysterious layers of the world to show us the science hidden in our daily lives.

Everything around us – trees, buildings, food, light, water, air and even ourselves – is composed of minute particles, smaller than a nanometer (a billionth of a meter). Quantum physics is the science of these particles and without it none of our electronic devices, from smartphones to computers and microwave ovens, would exist.

But quantum physics also pushes us to the very boundaries of what we know about science, reality and the structure of the universe. The world of quantum physics is an amazing place, where quantum particles can do weird and wonderful things, acting totally unlike the objects we…
