On October 4, 1957, a time of Cold War paranoia, the Soviet Union secretly launched the Earth's first artificial moon. No bigger than a basketball, the tiny satellite was powered by a car battery. Yet, for all its simplicity, Sputnik stunned the world.

The runaway success of the microchip processor may be nearing its end, with profound implications for our economy, society and way of life, even leaving Silicon Valley as a new Rust Belt, its technology obsolete. Step forward the quantum computer, which harnesses the power and complexity of the atomic realm, and may be useful in solving humanity's greatest challenges from climate change, to global starvation, to incurable diseases. Humanity's next great technological achievement already promises to be every bit as revolutionary as the transistor and microchip once were.

At the heart of the Milky Way, there is a distortion in the fabric of the Universe. Caused by something 4 million times bigger than our Sun, it is where space and time are so warped that everything within 12 million kilometres is trapped, even light. This region of no return is called the event horizon, and inside it lies the end of time as we know it. We have named it Sagittarius A* and it is a supermassive black hole.

When was the last time you read a grand statement, accompanied by a large number and wondered whether it could really be true? Statistics are vital in helping us tell stories - we see them in the papers, on social media and we hear them used in everyday conversation - and yet we doubt them more than ever. But numbers - in the right hands - have the power to change the world for the better. Contrary to popular belief, good statistics are not a trick, although they are a kind of magic.

In these Messenger Lectures, originally delivered at Cornell University and recorded for television by the BBC, Richard Feynman offers an overview of selected physical laws and gathers their common features into one broad principle of invariance. He maintains at the outset that the importance of a physical law is not "how clever we are to have foundit out but…how clever nature is to pay attention to it" and steers his discussions toward a final exposition of the elegance and simplicity of all scientific laws.

What's the nature of reality? Does the universe ever end? What is time, and does it even exist? These are the biggest imagination-stretching, brain-staggering questions in the universe - and here are their fascinating answers. From quantum weirdness to freaky cosmology (like white holes - which spew out matter instead of sucking it in), This Book Will Blow Your Mind takes you on an epic journey to the furthest extremes of science, to the things you never thought possible.

Shining a light on the most profound insights revealed by modern physics, Jim Al-Khalili invites us all to understand what this crucially important science tells us about the universe and the nature of reality itself. Al-Khalili begins by introducing the fundamental concepts of space, time, energy, and matter, and then describes the three pillars of modern physics - quantum theory, relativity, and thermodynamics - showing how all three must come together if we are ever to have a full understanding of reality.

Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. It communicates science by taking it seriously, wrestling with difficult concepts, and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely.

My Big TOE, written by a nuclear physicist in the language of contemporary culture, unifies science and philosophy, physics and metaphysics, mind and matter, purpose and meaning, the normal and the paranormal. The entirety of human experience (mind, body, and spirit) including both our objective and subjective worlds is brought together under one seamless scientific understanding. Section 5 presents the formal reality model in detail while Section 6 provides the wrap-up that puts everything discussed into an easily understood perspective.

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.

Dr Karl is on a mission to track down Awe and Wonder in the Universe. Why do wombats poo cubes? Do fish drink water? What nearly destroyed humanity on Halloween 2015? How do you use an incinerating toilet? Find out why we've sent a spacecraft with Dr Karl's name on it to kiss the sun, whether cannibalism is nutritious, how birds fly when they're asleep and much more. So strap in and get ready for a random ride through everything, from atoms to rogue planets and everything in between, including the Big Question - why does spaghetti always break into three parts?

Fans of xkcd ask Munroe a lot of strange questions: What if you tried to hit a baseball pitched at ninety percent the speed of light? How fast can you hit a speed bump while driving and live? If there was a robot apocalypse, how long would humanity last? What if everyone only had one soulmate? What would happen if the moon went away? In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators.

Astronomer Florian Freistetter has chosen 100 stars that have almost nothing in common. Some are bright and famous, some shine so feebly you need a huge telescope. There are big stars, small stars, nearby stars and faraway stars. Some died a while ago, others have not even yet come into being. Collectively they tell the story of the whole world, according to Freistetter. There is Algol, for example, the Demon Star, whose strange behaviour has long caused people sleepless nights.

'Bad Science’ hilariously exposed the tricks that quacks and journalists use to distort science, becoming a 400,000 copy bestseller. Now Ben Goldacre puts the $600bn global pharmaceutical industry under the microscope. What he reveals is a fascinating, terrifying mess.

From the discovery of entirely new kinds of galaxies to a window into cosmic ‘prehistory’, Bothwell shows us the universe as we’ve never seen it before - literally. Since the dawn of our species, people all over the world have gazed in awe at the night sky. But for all the beauty and wonder of the stars, when we look with just our eyes we are seeing and appreciating only a tiny fraction of the universe. What does the cosmos have in store for us beyond the phenomena we can see, from black holes to supernovas?

Dark Emu argues for a reconsideration of the 'hunter-gatherer' tag for pre-colonial Aboriginal Australians and attempts to rebut the colonial myths that have worked to justify dispossession. Accomplished author Bruce Pascoe provides compelling evidence from the diaries of early explorers that suggests that systems of food production and land management have been understated in modern retellings of Aboriginal history, and that a new look at Australia's past is required.

The brain is made up of 85 billion neurons, which are connected by over 100 trillion synapses. For over a century, a diverse array of researchers have been trying to find a language that can be used to capture the essence of what these neurons do and how they communicate - and how those communications create thoughts, perceptions, and actions. The language they were looking for was mathematics, and we would not be able to understand the brain as we do today without it.

Mystics and sages have long maintained that there exists an interconnecting cosmic field at the roots of reality that conserves and conveys information, a field known as the Akashic record. Recent discoveries in vacuum physics show that this Akashic field is real and has its equivalent in science's zero-point field that underlies space itself. This field consists of a subtle sea of fluctuating energies from which all things arise: atoms and galaxies, stars and planets, living beings, and even consciousness.

Life is the most extraordinary phenomenon in the known universe; but how does it work? Even in this age of cloning and synthetic biology, the remarkable truth remains: nobody has ever made anything living entirely out of dead material. Life remains the only way to make life. Are we missing a vital ingredient in its creation? Like Richard Dawkins' The Selfish Gene, which provided a new perspective on how evolution works, Life on the Edge alters our understanding of life's dynamics.
