Wormhole A wormhole, also known as an Einstein–Rosen bridge, is a hypothetical topological feature of spacetime that would fundamentally be a "shortcut" through spacetime. A wormhole is much like a tunnel with two ends each in separate points in spacetime. For a simplified notion of a wormhole, visualize space as a two-dimensional (2D) surface.

Discovery Education: Tech Tips Blog: Presentation Tools: Ready for the big screen with Web 2.0 Blah, blah, blah. You've been there. Sitting in a conference or meeting, trying to keep your eyes and mind focused on the topic. Listening to the speaker read the bullet points on the big screen. There's nothing more boring than a dull presentation. New Wormhole Theory Uses Space Photon Energy “Fluid” A new theory expands on other theories and adds photon energy “fluid” as a way to support wormholes. The introduction to the paper states the following. Wormholes are hypothetical geometrical structures connecting two universes or two distant parts of the same universe. For a simple visual explanation of a wormhole, consider spacetime visualized as a two-dimensional (2D) surface. If this surface is folded along a third dimension, it allows one to picture a wormhole “bridge”. [1] “A possible cause of the late-time cosmic acceleration is an exotic fluid with an equation of state lying within the phantom regime, i.e., w = p/ρ < −1.
Technology Tools for Teaching & Learning Used wisely, technology empowers students to take responsibility for their own learning. In Leonardo’s Laptop, Ben Shneiderman provides teachers with a powerful framework, Collect-Relate-Create-Donate (CRCD), for designing student-centered learning opportunities using computers. In particular, Shneiderman’s CRCD framework emphasizes the importance of the social aspects of learning in generating creative work. In CRCD projects, students research information, work collaboratively to create a meaningful product that demonstrates their learning, and contribute that project to a larger learning community.
New data confirms: Neutrinos are still traveling faster than light "It is worth pointing out, however, that the latest arXiv preprint lists 179 authors, while the original lists 174. Would you ever classify five people as "most of" 15? To make things more confusing . . . "four new people" have decided not to sign, according to Science. Now, none of the above numbers may match up . . .." The original 174 include a duplicate " F.

Gravitational-wave finding causes 'spring cleaning' in physics Detlev van Ravenswaay/Science Photo Library Artist's rendering of 'bubble universes' within a greater multiverse — an idea that some experts say was bolstered with this week's discovery of gravitational waves. On 17 March, astronomer John Kovac of the Harvard-Smithsonian Center for Astrophysics presented long-awaited evidence of gravitational waves — ripples in the fabric of space — that originated from the Big Bang during a period of dramatic expansion known as inflation. By the time the Sun set that day in Cambridge, Massachusetts, the first paper detailing some of the discovery’s consequences had already been posted online1, by cosmologist David Marsh of the Perimeter Institute for Theoretical Physics in Waterloo, Canada, and his colleagues. Cosmologist Marc Kamionkowski of Johns Hopkins University in Baltimore, Maryland, agrees that some axion models no longer work, “because they require inflation to operate at a lower energy scale than the one indicated by BICEP2”.
50+ Awesome Tips to Make a Great Presentations! I just came out of a day long conference, where I sat through over 10 presentations. 90 percent presentations were boring. Mind you, I am not saying that these presentations did not have great content to offer, but the way they were presented were very dull and boring. I am sure most of the other audience felt the same as well. In the past 15 years or so, I have sat through most presentations and more or less the statistics turn out to be the same. 9 out of 10 presentations made are extremely boring and that too accompanied by run-of-the-mill bullets points.

- Cool Projects With Skype 0 Comments November 9, 2011 By: Steven W. Anderson Nov 9 Written by: 11/9/2011 11:17 AM New Experiments to Pit Quantum Mechanics Against General Relativity It starts like a textbook physics experiment, with a ball attached to a spring. If a photon strikes the ball, the impact sets it oscillating very gently. But there’s a catch. Before reaching the ball, the photon encounters a half-silvered mirror, which reflects half of the light that strikes it and allows the other half to pass through. What happens next depends on which of two extremely well-tested but conflicting theories is correct: quantum mechanics or Einstein’s theory of general relativity; these describe the small- and large-scale properties of the universe, respectively. In a strange quantum mechanical effect called “superposition,” the photon simultaneously passes through and reflects backward off the mirror; it then both strikes and doesn’t strike the ball.
