If you think of the World Wide Web as a cloud of largely undifferentiated information, the mission of the company he’s about to unveil, Radar Networks, is to take that cloud and impose order on it. Not just any order, but a very special kind known to experts by one of the hottest buzzwords in computer science today: the semantic Web. For all the wonders that today’s Web can deliver to your fingertips — the Norwegian word for ice cream, a seat on the next flight to Paris, the best price for a Clash CD — it has a fundamental flaw. It’s basically a compendium of billions of text documents designed to be read by humans. You can search it for keywords, but the results aren’t much use until you sort through them to find the page that has the info you want. To take the Web to the next level — to move from Web 2.0 to Web 3.0 — the information in those documents will have to be turned into data that a machine can read and evaluate on its own. Only then will computers be able to take over tasks we now do by hand: find the nearest restaurant, book the best flight, buy the cheapest CD.

Why do the poor often seem happier than the rich? Must a society lose its traditions in order to move into the future? How do you reconcile a commitment to non-violence when faced with violence? These are some of the questions posed to His Holiness the Dalai Lama by filmmaker and explorer Rick Ray. Ray examines some of the fundamental questions of our time by weaving together observations from his own journeys throughout India and the Middle East, and the wisdom of an extraordinary spiritual leader.
In an era when many religious and political leaders are viewed with suspicion, and when cynical agendas rule both government and clergy, the Dalai Lama is undeniably authentic. Along with Martin Luther King, Gandhi and Jesus, this great leader inspires millions and has influenced the world in so many ways.

Back around the early 1900s, the universe was a fairly simple place. It was static, had always been there, and largely consisted of our own galaxy and a few neighboring bits of matter. Over the course of the 20th century, that view collapsed. Many sources of light were revealed not be stars, but rather galaxies like (and, in many cases, unlike) our own. Distant galaxies were found to be rocketing away from us, propelled by the unfolding of the universe itself, which has accelerated since the big bang. Modern cosmology has revealed a universe teeming with dark matter and unseen energy, entering a new stage of inflation.

“My paper introduces a new mathematical model that we can use to derive new details about the properties of a quantum state as it travels through the Big Bounce, which replaces the classical idea of a Big Bang as the beginning of our universe,” said Martin Bojowald, assistant professor of physics at Penn State. Bojowald’s research also suggests that, although it is possible to learn about many properties of the earlier universe, we always will be uncertain about some of these properties because his calculations reveal a “cosmic forgetfulness” that results from the extreme quantum forces during the Big Bounce.
