All the matter and light we can see in the universe makes up a trivial 5 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...

Imagine you’re trying to build the biggest, most awesome LEGO castle ever. You gather all your colorful bricks—the reds, blues, yellows, and greens. You plan your design, start stacking the bricks, and build towers, walls, gates, and secret tunnels. Everything’s going great. But suddenly, something odd starts to happen. Parts of your castle stick together more tightly than they should. Some towers refuse to fall over, no matter how much you poke them. And even stranger, the whole play area you’re building on starts stretching.

From the author of the acclaimed The Epigenetics Revolution comes another thrilling exploration of the cutting edge of human science. For decades after the structure of DNA was identified, scientists focused purely on genes, the regions of the genome that contain codes for the production of...

Ninety-five percent of the universe is invisible. Dark matter holds galaxies together; dark energy tears space apart. For a quarter of a century, these two phenomena have been treated as separate mysteries—independent entries in the cosmic ledger, unrelated in origin and opposite in effect. This book argues that they are the same mystery. Drawing on quantum field theory, general relativity, and a systems-theoretic perspective that spans disciplines, Boris Kriger proposes that the energy of empty space is not uniform.

On July 23, 1999, the Chandra X-Ray Observatory, the most powerful X-ray telescope ever built, was launched aboard the space shuttle Columbia. Since then, Chandra has given us a view of the universe that is largely hidden from telescopes sensitive only to visible light. In Chandra's Cosmos, Wallace H. Tucker uses a series of short, connected stories to describe the telescope's exploration of the hot, high-energy face of the universe.

Our historians today often only emphasize negative interactions between the races, and dismally fail to relay a COMPLETE HISTORY, which tells of how the noble ones of all races protected and helped one another in our country. From the inspiring examples of parents, grandparents, and ancestors, Debra undoubtedly drew strength. Many of their stories are in the opening chapters of the book. The narrative continues through the turbulent 1960s and 1970s.

What is matter? Matter is the stuff from which we and all the things in the world are made. Everything around us - from desks, to books, to our own bodies - are made of atoms, which are small enough that a million of them can fit across the breadth of a human hair. Inside every atom is a tiny nucleus and orbiting the nucleus is a cloud of electrons. The nucleus is made out of protons and neutrons, and by zooming in further, you would find that inside each there are even smaller particles: quarks.

Die Zeit. Wir teilen sie ein und achten auf sie, wir nehmen sie uns und schenken sie anderen. Doch sie rinnt uns auch durch die Finger oder zieht sich wie Kaugummi. Jeden Tag versuchen wir aufs Neue die Zeit zu beherrschen – und bekommen sie trotzdem nie richtig zu fassen. Was ist da also los in der vierten Dimension? Dieses Hörbuch – das erste des Teams vom Audible-Podcast „Sag mal, du als Physiker" – geht dem Wesen der Zeit auf den Grund. Was ist das genau, was da verrinnt? Und können wir die Zeit beschleunigen oder verlangsamen? Vielleicht sogar umdrehen oder uns mehr davon verschaffen?

Whether searching for extra-terrestrial life, managing the effects of space weather or learning about dark matter, the study astrophysics has profound implications for us all. NASA scientist and astronomer Sten Odenwald explains the key concepts of this vast topic, bringing clarity to some of the great mysteries of space.

In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature.

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.
