Stephen Hawking: Master of the Universe (Part 1 of 10)

In his post as Lucasian Professor of Mathematics at Cambridge University, he counts Sir Isaac Newton (1642--1727) amongst his predecessors. And he was born 300 years to the day after the avant-garde astronomer, Galileo Galilei (1564--1642). Following a devastating diagnosis of motor neurone disease in 1963, Hawking was given two years to live. Yet 44 years later, he still hopes to solve the big problem of physics, that of unifying quantum mechanics and Einstein's theory of relativity. Doing so will produce a set of laws that will explain everything in the universe, including how it all began - a breakthrough aptly dubbed the 'Theory of Everything'. Hawking felt that he was on the brink of this breakthrough a long time ago. When he published his surprising best-seller 'A Brief History of Time' in 1988, he expressed a certainty that the Theory of Everything was imminent. However, twenty years later, it still eludes Hawking and the scientific community. Frustratingly, Hawking's condition is worsening. His only way of communicating now is through one cheek muscle. Will he find the theory before it is too late? This two-episode documentary from the UK's Channel 4 is both a portrait of Hawking and an attempt to explain his work to non-scientific types. It conveys the basics of quantum mechanics and the theory of relativity in an easy-to-understand manner and does very well to acquaint viewers with Hawking's extraordinary life and character. A thoroughly enjoyable, inspiring and enlightening series!

Strong Photon-Photon Interactions and Meta-Materials

ABSTRACT Fun with Light: Strong Photon-Photon Interactions and Meta-Materials Presented by Jung-Tsung Shen The lightsaber is a supercool gadget that all of us would like to get one. It exhibits many novel light phenomena, notably the light blades of two lightsabers could interact with each other. Unfortunately it takes an enormous amount of energy to achieve that. One of the main difficulties of making a lightsaber is that photons normally do not interact with each other. In the first part of the talk, I will describe how to make photons interact with each other, which enables the capability of using photons to control photons. This capability has many potential applications in quantum communication and information processing, and other novel optoelectronics devices. Moreover, the configuration is well-suited for on-chip all solid-state implementations. In the second part of the talk, I will briefly explain what metamaterials are, and some novel optical tricks they can play, such as Harry Potter's invisibility cloak and super lens. In particular, I will discuss the mechanisms and properties of a special class of metamaterials -- metamaterials with ultra-high refractive index. Such artificial structures will be useful in many applications such as subwavelength lithography and imaging, broadband slow-light, and sensitive interferometer. (* The talk is for general audience with no background in these fields. *) Dr. Jung-Tsung Shen is currently a research associate at Stanford University, working on photon transport in nano-photonics, metamaterials, plasmonics, and thermal and energy transport in nano-structures. He obtained his PhD degree in physics in 2003 from MIT. He was also a graduate scholar at Bell Labs from year 1998 -2001. He will be an assistant professor at Washington University in St. Louis in September this year.

Spirit Science 12_3 - The Solution

After the Martians collapsed the Atlantean way of life, the Naacals didn't know what to do. They asked for help from the highest conscious beings in our universe, and they received a potential solution. If it could pull it off, we would become something incredibly new and different in the universe. If we did not, we would not survive. Our entire planet was walking a very thin line. www.thespiritscience.net Twitter - @spiritsciences Facebook - www.facebook.com/thespiritscience Flower of Life books - http://www.mediafire.com/?4zx4y9mhasjg5nz See page 104 Volume 1 for this portion of the Human History Story!

The Dancing Wu Li Masters by Gary Zukav

2 hr 41 min audio summary by author - Gary Zukav has written "the Bible" for those who are curious about the mind-expanding discoveries of advanced physics, but who have no scientific background. Like a Wu Li Master who would teach us wonder for the falling petal before speaking of gravity, Zukav writes in beautifully clear language--with no mathematical equations--opening our minds to the exciting new theories that are beginning to embrace the ultimate nature of our universe...Quantum mechanics, relativity, and beyond to the Einstein-Podolsky-Rosen effect and Bell's theorem. "Reality is what we take to be true. What we take to be true is what we believe. What we believe is based upon our perceptions. What we perceive depends upon what we look for. What we look for depends upon what we think. What we think depends upon what we perceive. What we perceive determines what we believe. What we believe determines what we take to be true. what we take to be true is our reality." EVERYTHING IS CONNECTED :)

It preserves many of the important features of general relativity, while at the same time employing quantization of both space and time at the Planck scale in the tradition of quantum mechanics. The technique of loop quantization was developed for the nonperturbative quantization of diffeomorphism-invariant gauge theory. Roughly, LQG tries to establish a quantum theory of gravity in which the very space, where all other physical phenomena occurs, becomes quantized.'

Towards a Spin Foam Model of Quantum Gravity

NOTE: pdf link for transparencies- http://math.ucr.edu/home/baez/loops05/loops05.pdf Probably not everyones cup of tea. A clip from a lecture by John Baez in conjunction with the LOOPS 'O5 series by the Max Planck Institute of Gravitation (Albert Einstein Institute) regarding a proposal for quantum gravity (the clip appears to start at page 14 of the transparencies). Date- 11th Oct 05. Source- http://math.ucr.edu/home/baez/loops05/ LOOPS '05- http://loops05.aei.mpg.de/ 'Spin foam models include several different classes of physical theories: lattice gauge theories, dynamical triangulation models of quantum gravity, "chain mail" quantum field theories, and topological string theories. Is there a spin foam model of quantum gravity in 4 dimensions? To address this question, we review recent work on causal dynamical triangulations and the renormalization group. This suggests that quantum gravity is a well-defined theory with the curious property that spacetime is effectively 4-dimensional at large distance scales, but 2-dimensional at very short distance scales. This is just what one might expect from a spin foam model, since spacetime is fundamentally 2-dimensional in these theories. We discuss properties a spin foam model should have in order to approximate general relativity at large distance scales.'
