Ever wondered what's going on inside your head? You are your brain. Everything that makes you you, and all your experiences of the world, are somehow conjured up by 1.4 kilograms of grey matter inside your skull. That might seem impossible, but science has advanced so much that we now understand not just its structures and inner workings but also...

Sometime in the future, the intelligence of machines will exceed that of human brain power. So, are we on the edge of an AI-pocalypse with superintelligent devices superseding humanity, as predicted by Stephen Hawking? Or will this herald a kind of Utopia, with machines doing a far better job at complex tasks than us? You might not realise it, but...

How did we get here? All cultures have a creation story, but a little over 150 years ago Charles Darwin introduced a revolutionary new one. We, and all living things, exist because of the action of evolution on the first simple life form and its descendants. We now know that it has taken 3.8 billion years of work by the...

Think of a number between one and ten. No, hang on, let's make this interesting. Between zero and infinity. Even if you stick to the whole numbers, there are a lot to choose from - an infinite number in fact. Throw in decimal fractions and infinity suddenly gets an awful lot bigger (is that even possible?) And then there are...

Forget everything you thought you knew about reality. The world is a seriously bizarre place. Things can exist in two places at once and travel backwards and forwards in time. Waves and particles are one and the same, and objects change their behaviour according to whether they are being watched. This is not some alternative universe but the realm of...

What is this strange mental world that seems so essential to being human? The conscious mind brings together sensations, perceptions, thoughts and memories to generate the seamless movie of a person's life. It makes us aware of the world around us and our own self. How all this emerges from a kilogram of brain cells is one of the greatest...

Where did we come from? Where are we going? Homo sapiens is the most successful, most widespread, and most influential species ever to walk the Earth. In the blink of an evolutionary eye, we have spread around the globe, taken control of Earth's biological and mineral resources, transformed the environment, discovered the secrets of the universe, and travelled into space....

As you read this, billions of neutrinos from the sun are passing through your body, antimatter is sprouting from your dinner, and the core of your being is a chaotic mess of particles known only as quarks and gluons. If the recent discovery of the Higgs boson piqued your interest, then Why the Universe Exists will take you deeper into...
