On September 14, 2015, after 50 years of searching, gravitational waves were detected for the first time, and astronomy changed forever. Up until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays, and the rest. But gravitational waves - ripples in the fabric of space and time - are unrelenting, passing through barriers that stop light dead.

In 2003, Russian physicists Andre Geim and Konstantin Novoselov found a way to produce graphene - the thinnest substance in the world - by using sticky tape to separate an atom-thick layer from a block of graphite. Their efforts would win the 2010 Nobel Prize for Physics, and now the applications of graphene and other two-dimensional substances form a worldwide industry.

Asked to name a great physicist, most people would mention Newton or Einstein, Feynman or Hawking. But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list. Maxwell, an unassuming Victorian Scotsman, explained how we perceive color. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.

Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the street to the chemist, but that's just peanuts to space.' Douglas Adams, Hitch-hiker's Guide to the Galaxy.We human beings have trouble with infinity - yet infinity is a surprisingly human subject. Philosophers and mathematicians have gone mad contemplating its nature and complexity - yet it is a concept routinely used by schoolchildren. Exploring the infinite is a

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

Brian Clegg was always fascinated by Isaac Asimov’s classic Foundation series of books, in which the future is predicted using sophisticated mathematical modeling of human psychology and behavior. Only much later did he realize that Asimov’s "psychohistory" had a real-world equivalent: game theory. Originating in the study of probabilistic gambling games that depend on a random source—the throw of a dice or the toss of a coin—game theory soon came to be applied to human interactions: essentially, what was the best strategy to win whatever you were doing?

Computer technology has improved exponentially over the last 50 years. But the headroom for bigger and better electronic solutions is running out. Our best hope is to engage the power of quantum physics. “Quantum algorithms” had already been written long before hardware was built. These would enable, for example, a quantum computer to exponentially speed up an information search or crack the mathematical trick behind internet security.

The volumes of data we now access can give unparalleled abilities to make predictions, respond to customer demand, and solve problems. But Big Brother’s shadow hovers over it. Although big data can set us free and enhance our lives, it has the potential to create an underclass and a totalitarian state. With big data ever present, you can’t afford to ignore it. In this book, acclaimed science writer Brian Clegg - a habitual early adopter of new technology - brings big data to life.

Physics informs our understanding of how the world works - but more than that, key breakthroughs in physics have transformed everyday life. We journey back to 10 separate days in history to understand how particular breakthroughs were achieved, meet the individuals responsible and see how each breakthrough has influenced our lives.

Brainjacking takes us on a journey through advertising and marketing's attempts to understand and influence our thoughts and desires, from the earliest billboards to the technologies of the future. To discover how science intersects with our desires and decisions, the book pulls together three strands that have a huge impact on our lives: advertising, how much privacy we can and should have in the new electronic world, and how to draw the line been information and influence. With Brian Clegg as your guide, this is a book that will help you unpick the insidious world of brainjacking

From the crystalline perfection of the snowflake to the transfer of energy from the Sun, science lies at the heart of the weather and our understanding of it. In recent years, weather science has moved to the leading edge with advanced modelling, versatile use of satellite data and a better understanding of mathematical chaos. This is a true example of hot science at work.

Biomimetics literally means emulating biology—and in a broader sense the term covers technological advances where the original inspiration came from nature. The Earth is a vast laboratory where the mechanisms of natural selection have enabled evolutionary solutions to be developed to a wide range of problems. Science writer Brian Clegg looks at how humans have piggybacked on natural experimentation, redeploying a solution to create things that make our lives easier.

In biological terms human beings haven't evolved in 100,000 years - but thanks to our amazing brains, we are able to upgrade ourselves to add capabilities that have taken other creatures millions of years to evolve. Thanks to this "unnatural" evolution, we are already Human 2.0. In an effort to live longer, become more attractive to the opposite sex, be better able to defend ourselves, make the most of our brains, repair damaged bodies, we have transformed ourselves. To do this, we have done many things: created artificial skin in the form of clothing, for instance. In the future we will ...
