When he was six years old, Roger Penrose discovered a sundial in a clearing near his house. Through that machine made of light, shadow, and time, Roger glimpsed a “world behind the world” of transcendently beautiful geometry. It spurred him on a journey to become one of the world’s most influential mathematicians, philosophers, and physicists. Penrose would prove the limitations of general relativity, set a new agenda for theoretical physics, and astound colleagues and admirers with the elegance and beauty of his discoveries.

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.

A modern classic, Einstein's Dreams is a fictional collage of stories dreamed by Albert Einstein in 1905, when he worked in a patent office in Switzerland. As the defiant but sensitive young genius is creating his theory of relativity, a new conception of time, he imagines many possible worlds. In one, time is circular, and people are fated to repeat their triumphs and failures over and over. In another, there is a place where time stands still, visited by lovers and parents clinging to their children.

This short, smart book tells you everything you need to know about "nothing". What remains when you take all the matter away? Can empty space - "nothing" - exist? To answer these questions, eminent scientist Frank Close takes us on a lively and accessible journey that ranges from ancient ideas and cultural superstitions to the frontiers of current research, illuminating the story of how scientists have explored the void and the rich discoveries they have made there.

Humanity has long looked to the sky and marveled at the world around us. We've wondered why the world is the way it is and whether it has to be that way. And we dream of a time when we have developed a theory of everything—a theory that answers all questions. Einstein's Unfinished Dream explores the cutting-edge research of modern particle physicists that pushes us slowly towards a theory of everything....

England, 1840. For the two decades following the death of her beloved sister, Jane, Cassandra Austen has lived alone and unwed, spending her days visiting friends and relations and quietly, purposefully working to preserve her sister’s reputation. Now in her 60s and increasingly frail, Cassandra goes to stay with the Fowles of Kintbury, family of her long-dead fiancé, in search of a trove of Jane’s letters. Dodging her hostess and a meddlesome housemaid, Cassandra eventually hunts down the letters and confronts the secrets they hold.

But as the decades pass and the characters weave in and out of each other's lives, love, death, and two secrets wait in ambush for them.

Bright, attractive, and well-connected, in any other family the Churchill girls - Diana, Sarah, Marigold, and Mary - would have shone. But they were not in another family, they were Churchills and neither they nor anyone else could ever forget it. From their father - "the greatest Englishman" - to their brother, golden boy Randolph, to their eccentric and exciting cousins, the Mitford Girls, they were surrounded by a clan of larger-than-life characters which often saw them overlooked.

Thirty years have passed since Greta left Marchmont Hall, a grand and beautiful house nestled in the hills of rural Monmouthshire. But when she returns to the Hall for Christmas she has no recollection of her past association with it – the result of a tragic accident that has blanked out more than two decades of her life. Then, during a walk through the wintry landscape, she stumbles across a grave in the woods and the weathered inscription on the headstone tells her that a little boy is buried here.
