Science Universe

Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place that might sound and smell very much like our own, but that looks completely different. It plays by different rules. Certainly it refuses to succumb to the quaint notion that universes are ruled by pure logic and the harmony of numbers. But just because the Disc is different doesn't mean that some things don't stay the same.

As a MechWarrior of the Draconis Combine, Minobu Tetsuhara was bound by Bushido - a code that demands loyal service - to the devious Warlord Grieg Samsonov. But when Minobu came upon a strange blue-and-gold Archer, Bushido also dictated that he not destroy the honorable but helpless warrior. And so begins the BattleTech Chronicles, books four, five, and six to complete the collection....

Veteran sailor and writer Christian Williams invites us along once again on a 5,000-mile voyage of discovery around the North Pacific. Equipped with a new boat, a well-stocked toolbox, and the entire history of philosophic thought, he takes us as crew through squalls and calms deep into a laboratory of the universe that exists only out of sight of land. Funny, erudite, and at times deeply personal, Philosophy of Sailing explores who we are and how encounters with the unknown can be a path to revelation and joy.

Thirty meters tall, 70 tons of quick-striding death and destruction, the armored war machines called BattleMechs are the frontline forces of the crumbling star empire locked in the horror of the endless Succession Wars. Their pilots are MechWarriors, 31st-century knights riding armored machines powerful enough to take a city apart. Grayson Death Carlyle had been training to be a MechWarrior since he was 10 years old, but his graduation came sooner than expected.

For generations, Prosper Station has thrived under the guidance of its Honoured Ancestress: born of a human womb, the station's artificial intelligence has offered guidance and protection to its human relatives. But war has come to the Dai Viet Empire. Prosper's brightest minds have been called away to defend the emperor; and a flood of disorientated refugees strain the station's resources.

Over the past few decades, a handful of scientists have been racing to explain a disturbing aspect of our universe: only four percent of it consists of the matter that makes up you, me, our books, and every star and planet. The rest is completely unknown. Richard Panek tells the dramatic story of the quest to find this “dark” matter and an even more bizarre substance called “dark energy”. This is perhaps the greatest mystery in all of science, and solving it will bring fame, funding, and certainly a Nobel Prize.

Joined by a sly Demoness with an ancient past and a shy Valkyrie hoping to prove herself in battle, they'll find excitement and enjoyment as they level and grow in power.

For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. In harnessing its power, we have created a world of wonders—complete with roller coasters and radar, computer networks and psychopharmaceuticals.

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.

On March 21, 2013, the European Space Agency released a map of the afterglow of the big bang. Taking in 440 sextillion kilometers of space and 13.8 billion years of time, it is physically impossible to make a better map: We will never see the early universe in more detail. On the one hand, such a view is the apotheosis of modern cosmology; on the other, it threatens to undermine almost everything we hold cosmologically sacrosanct.
