What Everyday Objects Tell Us About the Universe01 JUNE, 2010 by Maria Popova
Why your reflection is a matter of chance, or how to fit everything that ever existed on a USB stick.
We recently raved about an excellent article about the early history of the universe, quantum reality and the origins of information. Turns out its author, California Institute of Technology astronomer and New Scientist cosmology consultant Marcus Chown, didn't stop there.
His new book, The Matchbox That Ate a Forty-Ton Truck, offers a fascinating anthology of wisdom bites about the universe gleaned from everyday objects.
Today, we sit down with Marcus to probe into some of the book's peculiar contentions and quench our curiosity about just how one comes to see quantum theory in bananas.
If the Sun were made of bananas it wouldn't make much difference
How did the inspiration for the book come? Was it a single "a-ha!" moment, an encounter with a particular mundane object that gleaned surprising revelation about something much larger, or was it more of a buildup of insights?
Marcus Chown: While doing publicity, I tend to latch onto everyday observations and relate them to deep physics. Recently, I wanted to highlight the paradox that spawned quantum theory. So I drew people's attention to a light bulb and pointed out the light waves coming out are about 5000 times bigger than the atoms. "Say, I opened this matchbox", I said, "and out drove a 40-tonne truck. That's what it's like for light streaming out of that light bulb." And one day, a light bulb did go on in my head. I thought, why don't I write a book about what everyday things tell us about the Universe?

What's your favorite mundane-object-turned-quantum-oracle?
MC: It still amazes me that something as mundane and everyday as your face reflected in a window tells you about the most shocking discovery in the history of science — that the universe is founded on random chance, the roll of a quantum dice, that ultimately things happen for no reason at all. Einstein was so appalled by this that he famously declared "God does not play dice with the Universe".
The irony is that not only does God play dice but, if He did not, there would be no universe of the beauty and complexity we find ourselves in.

Historically, humanity's beliefs about the universe have regularly turned out to be tragicomically misguided. With what degree of certainty do you foresee the ideas outlined in your book surviving the test of time and scientific evolution?
MC: Well, of course, science is provisional. It is the best description we have of the world at this moment in time. Scientists are always looking for observations that will falsify their theories in their quest to lay bare ever deeper layers of reality. But, even though we know Einstein's theory of gravity, for instance, is not the last word – because it breaks down inside black holes and in the big bang — we know it contains profound truth. And that's what I think about the ideas in my book. Most are likely to be modified and extended in the fullness of time but they nevertheless contain a large amount of truth.

Howard Gardner's theory of multiple intelligences is a favorite here at Brain Pickings, and a recent New York Times article outlined a similar theory of differences in creative capacity. Do you think this associative ability to look at the mundane and extrapolate the omnipotent is a unique kind of mental wiring, a mark of scientific genius shared necessary for groundbreaking discovery and shared by history's most iconic scientists? Or is it something we can learn to do?
MC: Of course, this is what scientists do. They try to tease out the general, unifying principles which underlie as wide a range of phenomena as possible. Darwin, for instance, in one of the greatest strokes of genius in history, saw the driving principle — evolution by natural selection – that was generating the bewildering complexity of the natural world. This kind of thing – extrapolating from the specific to the general — is very hard. But I don't believe it is special to geniuses (I don't think much is special to geniuses!). Anyone can learn. It's just that most of us don't practice much!
