Evidence that the universe rapidly expanded in its first few nanoseconds has been found by an instrument in Antarctica: Gravitational waves, which have long eluded astronomers, were spotted, supporting this cosmic inflation model. Read more here: http://goo.gl/WsCive

Origins Project is pleased to present a top-notch discussion of the nature of the universe, the possibilities of a multiverse, and exciting discoveries in fundamental physics. Join Nobel Laureates Frank Wilczek, David Gross, and Brian Schmidt, as well as esteemed scientists Wendy Freedman, Maria Spiropulu, and Lawrence Krauss for an out-of-this-world conversation.
We live in one universe. Is it unique? Is it required? How can we find out? These issues touch on the forefront of particles physics and cosmology, from the Large Hadron Collider to the edges of the visible Universe. This panel will bring together the leading scientists and thinkers working at both these frontiers to discuss how we can probe the fundamental fabric of reality.
Big History surveys the past at multiple scales, from those of cosmology to those of human history. Do cosmological scales reduce humans to insignificance? Surprisingly, they make us seem extraordinarily interesting if you focus not on spatial and chronological scales, but on another dimension, complexity. There are good reasons for thinking that modern human societies represent a remarkably high level of complexity. Our very existence is odd on planetary and perhaps cosmological scales. How can a universe ruled by the second law generate such complexity? And how likely is it that we are unique at cosmological scales?
This lecture will be followed by a drinks reception, all welcome.

We all know that the universe is big. It's very big...but just how large is it? Join Anthony as he discusses some pretty astounding new theories about the universe, and how we're extremely close to finding out almost exactly how big it is.

Inflation, an enduring theory about our universe and how it was formed, proposes that just after the Big Bang, the universe underwent a period of rapid expansion. The theory has historically done a good job explaining a wide range of phenomena we see in the cosmos today. The originator of the idea of cosmic inflation, Alan Guth, explains the theory.
For millennia, shamans and philosophers, believers and nonbelievers, artists and scientists have tried to make sense of our existence by suggesting that everything is connected, that a mysterious Oneness binds us to everything else. People go to temples, churches, mosques, and synagogues to pray to their divine incarnation of Oneness. Following a surprisingly similar notion, scientists have long asserted that under Nature’s apparent complexity there is a simpler underlying reality. In its modern incarnation, this Theory of Everything would unite the physical laws governing very large bodies (Einstein’s theory of relativity) and those governing tiny ones (quantum mechanics) into a single framework. But despite the brave efforts of many powerful minds, the Theory of Everything remains elusive. It turns out that the universe is not elegant. It is gloriously messy.
Marcelo Gleiser (born 19 March 1959) is a Brazilian-born physicist and astronomer.
Gleiser is a world-renowned theoretical physicist and author. He received his bachelor's degree in 1981 from the Pontifícia Universidade Católica do Rio de Janeiro, his M.Sc. degree in 1982 from the Universidade Federal do Rio de Janeiro, and his Ph.D. in 1986 from King's College London. After this he worked as a postdoc at Fermilab until 1988 and from then until 1991 at the Kavli Institute for Theoretical Physics. Since 1991, he has taught at Dartmouth College, where he was awarded the Appleton Professorship of Natural Philosophy in 1999, and is currently a professor of physics and astronomy.
Gleiser's current research interests include the physics of the early Universe, the properties of solitons in quantum field theories, and questions related to the origin of life on Earth and elsewhere in the Universe. He has contributed seminal ideas in the interface between particle physics and cosmology, in particular on the dynamics of phase transitions and spontaneous symmetry breaking. He is also the co-discoverer of "oscillons," time-dependent long-lived field configurations which are present in many physical systems from cosmology to vibrating grains. The author of over one hundred papers in peer-reviewed journals, Gleiser has also published three popular science books in the US, A Tear at the Edge of Creation (2010), The Prophet and the Astronomer (2002), and The Dancing Universe (1997/2005). "A Tear at the Edge of Creation" was published in 12 languages. His books offer a uniquely broad cultural view of science and its relation with religion and philosophy. "The Prophet and the Astronomer" and "The Dancing Universe" won the Jabuti Award for best nonfiction in Brazil. Apart from many contributions to magazines and newspapers in the US and abroad, Gleiser writes a weekly science column for the Brazilian Folha de São Paulo newspaper. He is a leading science popularizer in his native country. He is a Fellow of the American Physical Society, and currently serves as a General Councilor. He has been awarded the Presidential Faculty Fellows Award from the White House and the National Science Foundation. He is also a member of the Brazilian Academy of Philosophy. In Brazil, he received the José Reis Award for the Public Understanding of Science from the Brazilian National Research Council. He has been featured in several TV documentaries, including "Stephen Hawking's Universe," the History Channel's "Beyond the Big Bang" (2007) and "How Life Began" (2008), as well as many radio programs, including Fresh Air, Radiolab, On Being, and many others. In Brazil, his two science series for TV Globo's "Fantastico" were watched by over 30 million viewers. He is the co-founder of the science and culture blog 13.7 hosted by National Public Radio, a leading science blog.
In this deeply original book, science writer Anil Ananthaswamy sets out in search of the telescopes and detectors that promise to answer the biggest questions in modern cosmology. Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own?
Ananthaswamy soon finds himself at the ends of the earth in remote and sometimes dangerous places. Take the Atacama Desert in the Chilean Andes, one of the coldest, driest places on the planet, where not even a blade of grass can survive. Its spectacularly clear skies and dry atmosphere allow astronomers to gather brilliant images of galaxies billions of light-years away. Ananthaswamy takes us inside the European Southern Observatory s Very Large Telescope on Mount Paranal, where four massive domes open to the sky each night "like dragons waking up."
The Second International Conference on Quantum Technologies will take place in Moscow on July 20-24, 2013. It is organized by the Russian Quantum Center . We expect this interdisciplinary meeting to bring together over 100 experts from various fields of physics exploring frontiers of quantum technologies and include sessions on
ultra-cold atoms and molecules
More than 150 of the world’s top physicists will be in attendance, including Seth Lloyd , MIT professor and director of the Center for Extreme Quantum Information Theory . The programming for the conference includes presentations by world-class scientists in the field of quantum technologies, critical panel discussions, including “Commercialization of Scientific Applications: What are the gadgets of the 2020s,” and a public lecture by the Nobel laureate in Physics, Wolfgang Ketterle on “The Century of Quantum Mechanics.”
