Quotes from Why Does E=mc²? (And Why Should We Care?)

“In science, there are no universal truths, just views of the world that have yet to be shown to be false.”
― Brian Cox, quote from Why Does E=mc²? (And Why Should We Care?)

“Our experience teaches us that there are indeed laws of nature, regularities in the way things behave, and that these laws are best expressed using the language of mathematics. This raises the interesting possibility that mathematical consistency might be used to guide us, along with experimental observation, to the laws that describe physical reality, and this has proved to be the case time and again throughout the history of science. We will see this happen during the course of this book, and it is truly one of the wonderful mysteries of our universe that it should be so.”
― Brian Cox, quote from Why Does E=mc²? (And Why Should We Care?)

“Perhaps we should not be too surprised that nature sometimes appears counterintuitive to a tribe of observant, carbon-based ape descendants roaming around on the surface of a rocky world orbiting an unremarkable middle-aged star at the outer edge of the Milky Way galaxy.”
― Brian Cox, quote from Why Does E=mc²? (And Why Should We Care?)

“If there is one thing we try to teach our students when they first arrive at the University of Manchester, ready to learn to be physicists, it is that everyone gets confused and stuck. Very few people understand difficult concepts the first time they encounter them, and the way to a deeper understanding is to move forward with small steps. In the words of Douglas Adams: 'Don’t panic!”
― Brian Cox, quote from Why Does E=mc²? (And Why Should We Care?)

“Michael Faraday, the son of a Yorkshire blacksmith, was born in south London in 1791. He was self-educated, leaving school at fourteen to become an apprentice bookbinder. He engineered his own lucky break into the world of professional science after attending a lecture in London by the Cornish scientist Sir Humphry Davy in 1811. Faraday sent the notes he had taken at the lecture to Davy, who was so impressed by Faraday’s diligent transcription that he appointed him his scientific assistant. Faraday went on to become a giant of nineteenth-century science, widely acknowledged to have been one of the greatest experimental physicists of all time. Davy is quoted as saying that Faraday was his greatest scientific discovery.”
― Brian Cox, quote from Why Does E=mc²? (And Why Should We Care?)

“Imagine that light is shining out from a flashlight. According to common sense, if we run fast enough we could in principle catch up with the front of the beam of light as it advances forward. Common sense might even suggest that we could jog alongside the front of the beam if we managed to run at the speed of light. But if we are to follow Maxwell’s equations to the letter, then no matter how fast we run, the beam still recedes away from us at a speed of 299,792,458 meters per second.”
― Brian Cox, quote from Why Does E=mc²? (And Why Should We Care?)

“It’s worth taking a brief pause here to ponder what has happened. Using only Pythagoras’ theorem and Einstein’s assumption about the speed of light being the same for everyone, we derived a mathematical formula that allowed us to predict the lengthening of the lifetime of a subatomic particle called a muon when that muon is accelerated around a particle accelerator in Brookhaven to 99.94 percent of the speed of light. Our prediction was that it should live 29 times longer than a muon standing still, and this prediction agrees exactly with what was seen by the scientists at Brookhaven. The more you think about this, the more wonderful it is. Welcome to the world of physics!”
― Brian Cox, quote from Why Does E=mc²? (And Why Should We Care?)

“That dizzying feeling of confusion, if (hopefully) followed by an epiphany of clarity, is the joy of science. If the reader is feeling the former, we hope to deliver the latter by the end of the book.”
― Brian Cox, quote from Why Does E=mc²? (And Why Should We Care?)

“Later, we shall see that if it were possible to exceed the speed of light, we could construct time machines capable of transporting us backward through history to any point in the past. We could imagine journeying back to a time before we were born and, by accident or design, preventing our parents from ever meeting. This makes for excellent science fiction, but it is no way to build a universe, and indeed Einstein found that the universe is not built like this. Space and time are delicately interwoven in a way that prevents such paradoxes from occurring.”
― Brian Cox, quote from Why Does E=mc²? (And Why Should We Care?)

About the author

Popular quotes

“That’s how I know it was really love, I guess,” he says, his words bringing my head back to level, my eyes right to him. He’s still lost in the stars. “When you want something for someone else more than you want them to be here for you—when you just wish they had more time, rather than more time with you. I’m pretty sure that’s love.”
― Ginger Scott, quote from The Girl I Was Before

“The stench of the thing was overpowering, smelling like a combination of rotting meat and an overfilled portable toilet in the hottest South Dakota summer. And”
― K.L. Armstrong, quote from Odin's Ravens

“It was a kind of fire dance in which the stick was thrown and caught, and the flame, tossed and twirled, created sinuous shapes, circles and ever-moving patterns. Ancel's red hair created a pleasing aesthetic alongside the red and orange fire. And even without the hypnotic movement of the flame, the dance was beguiling, its difficulties made to look effortless, its physicality subtly erotic. Damen looked at Ancel with new respect. This performance required training, discipline and athleticism, which Damen admired. It was the first time that Damen had seen Veretian pets display skill in anything other than wearing clothes or climbing on top of one another.”
― C.S. Pacat, quote from Captive Prince: Volume One

“You are the king no doubt, but in one respect,
at least, I am your equal: the right to reply.
I claim that privilege too.
I am not your slave. I serve Apollo.
I don't need Creon to speak for me in public.

So,
you mock my blindness? Let me tell you this.
You with your precious eyes,
you're blind to the corruption in your life,
to the house you live in, those you live with-
who are your parents? Do you know? All unknowing
you are the scourge of your own flesh and blood,
the dead below the earth and the living here above,
and the double lash of your mother and your father's curse
will whip you from this land one day, their footfall
treading you down in terror, darkness shrouding
your eyes that now can see the light!

Soon, soon,
you'll scream aloud - what haven won't reverberate?
What rock of Cithaeron won't scream back in echo?
That day you learn the truth about your marriage,
the wedding-march that sang you into your halls,
the lusty voyage home to the fatal harbor!
And a crowd of other horrors you'd never dream
will level you with yourself and all your children.

There. Now smear us with insults - Creon, myself
and every word I've said. No man will ever
be rooted from the earth as brutally as you.”
― Sophocles, quote from The Three Theban Plays: Antigone / Oedipus the King / Oedipus at Colonus

“What are you girls, if not my very own heart growing up once and for all?”
― Mira Jacob, quote from The Sleepwalker's Guide to Dancing

We also accept submissions from our visitors and will select the quotes we feel are most appealing to the BookQuoters community.

Founded in 2023, BookQuoters has quickly become a large and vibrant community of people who share an affinity for books. Books are seen by some as a throwback to a previous world; conversely, gleaning the main ideas of a book via a quote or a quick summary is typical of the Information Age but is a habit disdained by some diehard readers. We feel that we have the best of both worlds at BookQuoters; we read books cover-to-cover but offer you some of the highlights. We hope you’ll join us.
