What is real? Really real? Real for everyone everywhere? This is essentially the philosophical question Amanda Gefter is exploring in this truly unique book. It’s part memoir, part philosophy, and part science. It’s a narration of her personal quest to find an answer to the ultimate question of life, the universe, and everything. It’s a story about how she finagles a job as a science journalist in order to talk to some of the most eminent people working in theoretical physics today, and it’s an exploration of the metaphysical implications of some of their ideas. (Reviewers note to reader: Metaphysics is the branch of philosophy that deals with the ultimate nature of reality. It’s kind of like real physics, especially theoretical physics, but without all the messy math and testability requirements.)
I write (soft) science fiction, but I’m not a scientist. Relativity seemed rational enough to me (after some mental gymnastics), but many of the implications of quantum mechanics boggled my mind. It could make accurate predictions, but it never really made sense. It was like a superposition of ‘true’ and ‘bat-crap crazy’. After joining Amanda on her search in the pages of this book, I feel I have a better intuitive grasp of entanglement, wave-particle duality, the uncertainty principle, and entropy than those I possessed before. My shaky understanding may still be dead wrong, of course, but at least I have some framework to give these ideas structure now.
This would have been enough for me to proclaim this a great science book for nonscientists. But it has more.
She shows us some of the major physicists of our time not as embodiments of their ideas but as real people who interact with the world around them much as we of lesser intellect do. They have personalities, egos, disagreements, and quirks. They are real people who also just happen to be brilliant scientists. As she related her interviews with them, I thought about young students who might be reading this and drawing inspiration from it. We sometimes put great achievers on pedestals, implying that greatness is out of reach for us ‘normal’ people. Gefter brings them down to earth, showing us their humanity and thereby reminding us that they are not so different from the rest of us.
I think this book also reminds us of the tenuous relationship between theory, experiment, and the ‘reality’ behind them. Experiments yield data and theories provide beautiful equations, but what are they telling us about the underlying reality (assuming there is some)? This seems largely open to interpretation, at least on the quantum level. Yeah, the math works, but what does it MEAN? Is the ‘thing’ found ‘real’ or is it just a data point that tells us about a relationship with other data points from a particular point of view? Apparently, the answers depend on the questions asked, and if those answers seem contradictory, it may be because some of our underlying assumptions are wrong.
Some books about science suggest that scientists are simply fine tuning, adding details to the standard model, and working out a few remaining unknowns, such as the nature of dark energy or whatever. Trespassing on Einstein’s Lawn, I think, is telling us something entirely different. There are still a great number of things to learn and new theories needed to make sense of them. Science is not almost done. It has barely begun. There remains much to discover and understand.
I found this book informative, thought provoking, and entertaining. I highly recommend it to anyone interested in science and philosophy.
