The World as a Hologram
Science vs. Spirituality: Deepak Chopra And Leonard Mlodinow Discuss 'War Of The Worldviews'
Article linked in Title.
See:
The debate between science and spirituality is framed as a knock down fight for truth with winner take all. But does it have to be that way? Deepak Chopra is a physician and one of the most highly regarded spiritual teachers in the world; and Leonard Mlodinow teaches at Cal Tech and co-authored, along with Stephen Hawking, "The Grand Design." Chopra and Mlodinow wrote "War of the Worldviews: Science vs. Spirituality" to help start an intelligent and civil conversation about this very hot subject.
In this hour long video, Deepak Chopra and Leonard Mlodinow debate science and spirituality moderated by Paul Brandeis Raushenbush, Senior Religion Editor for The Huffington Post. This conversation was streamed live on Oct. 4, 2011 on the date of the publication of "War of the Worldviews: Science vs. Spirituality" by Deepak Chopra and Leonard Mlodinow.

Lee Smolin: "Here is a metaphor due to Eric Weinstein that I would have put in the book had I heard it before. Let us take a different twist on the landscape of theories and consider the landscape of possible ideas about post standard model or quantum gravity physics that have been proposed. Height is proportional to the number of things the theory gets right. Since we don’t have a convincing case for the right theory yet, that is a high peak somewhere off in the distance. The existing approaches are hills of various heights that may or may not be connected, across some ridges and high valleys to the real peak. We assume the landscape is covered by fog so we can’t see where the real peak is, we can only feel around and detect slopes and local maxima.

Cohen-Glashow Argument
Bee:And for all I know you need a charge for Cherenkov radiation and neutrinos don't have one.
 |
| Fig. 1: Cerenkov radiation involves the nearly continuous emission of photons by a charged particle moving faster than the speed of light in its vicinity. The charged particle gradually radiates away its energy. Cohen-Glashow emission involves the occasional creation, near a speeding neutrino, of an electron-positron pair, in which the neutrino loses a large fraction of its energy in one step. |
But these details almost don’t matter, because Cohen and Glashow then put another chunk of powerful evidence on the table. They point out that neutrinos have been observed, at two other experiments, SuperKamiokande and IceCube, 100 to 1000 times more energetic than the neutrinos in OPERA’s beam. These neutrinos come out of the earth having traveled many hundreds or thousands of kilometers across interior of the planet. The fact that these neutrinos did not lose most of their energy while traveling all that distance implies that they, too, did not undergo CG emission. In short, they must have traveled very close to, and conservatively no more than about fifteen parts per billion faster than, the speed of light in empty space. (The limit from IceCube data may be as good as ten parts per trillion!)See: Is the OPERA Speedy Neutrino Experiment Self-Contradictory?

Geometry Leads us to the Truth?
"The end he (the artist) strives for is something else than a perfectly executed print. His aim is to depict dreams, ideas, or problems in such a way that other people can observe and consider them." - M.C. Escher
I too have always been interested at the idea of what we can see deeper then what we observe on the surface. As if an abstraction in the geometry may be leading when considering Polytopes and allotrope s or even Penrose Tilings as to the Truth?:)

A remarkable mosaic of atomsIn quasicrystals, we find the fascinating mosaics of the Arabic world reproduced at the level of atoms: regular patterns that never repeat themselves. However, the configuration found in quasicrystals was considered impossible, and Dan Shechtman had to fight a fierce battle against established science. The Nobel Prize in Chemistry 2011 has fundamentally altered how chemists conceive of solid matter. See: The Nobel Prize in Chemistry 2011 Dan Shechtman |
If the heart was free from the impurities of sin, and therefore lighter than the feather, then the dead person could enter the eternal afterlife.
My second tattoo will be as in the picture showing below on this blog site demonstrating and seen above is an ancient idea about "our heart" in relation to "the truth." How we weight that against one another and how the choices we make will have us asking whether we acted in accordance with that truth. That is "the final judgement" and if this is understood then we can access whether or not we have much more to learn. I know that setting right past mistakes is not an easy thing but if you at least start then that is part of the success of not of having to repeat them. Maybe repeat many times until you finally actually get it.
Well then,how does one simplify that picture of such Judgement in the Hall of Ma'at as to know that this message is alive and well in today's world and just as valid? How well will the tattooist portray this design? I'll have to give it to her so she has some time to look at it and decipher.:)

Proton Collision ->Decay to Muons and Muon Neutrinos ->Tau Neutrino ->
.....tau lepton may travel some tens of microns before decaying back into neutrino and charged tracks
See:
Before I comment on the result, let me give you a little background on the whole thing. Opera is a very innovative concept in neutrino detection. Its aim is to detect tau neutrino appearance in a beam of muon neutrinos. A Six-Sigma Signal Of Superluminal Neutrinos From Opera!
The OPERA result is based on the observation of over 15000 neutrino events measured at Gran Sasso, and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature’s cosmic speed limit. Given the potential far-reaching consequences of such a result, independent measurements are needed before the effect can either be refuted or firmly established. This is why the OPERA collaboration has decided to open the result to broader scrutiny. The collaboration’s result is available on the preprint server arxiv.orghttp://arxiv.org/abs/1109.4897.
In order to perform this study, the OPERA Collaboration teamed up with experts in metrology from CERN and other institutions to perform a series of high precision measurements of the distance between the source and the detector, and of the neutrinos’ time of flight. The distance between the origin of the neutrino beam and OPERA was measured with an uncertainty of 20 cm over the 730 km travel path. The neutrinos’ time of flight was determined with an accuracy of less than 10 nanoseconds by using sophisticated instruments including advanced GPS systems and atomic clocks. The time response of all elements of the CNGS beam line and of the OPERA detector has also been measured with great precision.

By classifying the neutrino interactions according to the type of neutrino involved (electron-neutrino or muon-neutrino) and counting their relative numbers as a function of the distance from their creation point, we conclude that the muon-neutrinos are "oscillating." See: STATEMENT: EVIDENCE FOR MASSIVE NEUTRINOS FOUND by Dave Casper

We present an analysis of atmospheric neutrino data from a 33.0 kiloton-year (535-day)exposure of the Super-Kamiokande detector. The data exhibit a zenith angle dependent de ficit of muon neutrinos which is inconsistent with expectations based on calculations of the atmospheric neutrino flux. Experimental biases and uncertainties in the prediction of neutrino fluxes and cross sections are unable to explain our observation. . Evidence for oscillation of atmospheric neutrinos

Cherenkov radiation
Taking the formalisms of electromagnetic radiation and supposing a tachyon had an electric charge—as there is no reason to suppose a priori that tachyons must be either neutral or charged—then a charged tachyon must lose energy as Cherenkov radiation[15]—just as ordinary charged particles do when they exceed the local speed of light in a medium. A charged tachyon traveling in a vacuum therefore undergoes a constant proper time acceleration and, by necessity, its worldline forms a hyperbola in space-time. However, as we have seen, reducing a tachyon's energy increases its speed, so that the single hyperbola formed is of two oppositely charged tachyons with opposite momenta (same magnitude, opposite sign) which annihilate each other when they simultaneously reach infinite speed at the same place in space. (At infinite speed the two tachyons have no energy each and finite momentum of opposite direction, so no conservation laws are violated in their mutual annihilation. The time of annihilation is frame dependent.) Even an electrically neutral tachyon would be expected to lose energy via gravitational Cherenkov radiation, because it has a gravitational mass, and therefore increase in speed as it travels, as described above. See: Tachyon

| An early set of experiments with a facility called the solar neutrino telescope, measured the rate of neutrino emission from the sun at only one third of the expected flux. Often referred to as the Solar Neutrino Problem, this deficiency of neutrinos has been difficult to explain. Recent results from the Sudbury Neutrino Observatory suggest that a fraction of the electron neutrinos produced by the sun are transformed into muon neutrinos on the way to the earth. The observations at Sudbury are consistent with the solar models of neutrino flux assuming that this "neutrino oscillation" is responsible for observation of neutrinos other than electron neutrinos.

P.I. Chats: Faster-than-light neutrinos?
Measurements by GPS confirm that the neutrinos identified by the Super-Kamiokande detector were indeed produced on the east coast of Japan. The physicists therefore estimate that the results obtained point to a 99.3% probability that electron neutrino appearance was detected.Neutrino Oscillations Caught in the Act

P.I. Chats: Faster-than-light neutrinos?
Abstract: Can neutrinos really travel faster than light? Recently released experimental data from CERN suggests that they can. Join host Dr. Richard Epp and a panel of Perimeter Institute scientists in a live webinar to discuss this unexpected and puzzling experimental result, and some theoretical questions it might raise.

Using the NuMI beam to search for electron neutrino appearance.
The NOνA Experiment (Fermilab E929) will construct a detector optimized for electron neutrino detection in the existing NuMI neutrino beam. The primary goal of the experiment is to search for evidence of muon to electron neutrino oscillations. This oscillation, if it occurs, holds the key to many of the unanswered questions in neutrino oscillation physics. In addition to providing a measurement of the last unknown mixing angle, θ13, this oscillation channel opens the possibility of seeing matter/anti-matter asymmetries in neutrinos and determination of the ordering of the neutrino mass states.See:The NOνA Experiment at Fermilab (E929)

Wiki Growth Over Time
This is a project conducted by ChrisDavis and IgorNikolic to visualize the growth of wiki.tudelft.nl since its beginning in late 2004. Since then, it has grown to over 10,000 pages, and is now part of the officially supported ICT infrastructure of Delft University of Technology. This wiki is meant to be a free-form repository of information where people contribute content that helps with their research. This often takes the form of pages documenting articles that people have read, "how to" pages, and records of conferences and meetings.Project Motivation
This is a visualization of the evolution of wiki.tudelft.nl from the very beginning, 5 years ago. Each node is a page, links are connections between pages. Graph is laid out using a force-directed algorithm, where the edges (links between pages) pull the nodes (pages) together, and the nodes (pages) repel each other. This means that the more tightly connected nodes will be closer together than weakly connected ones, which are pushed to the outside. The entire thing is created using Prefuse (http://prefuse.org/), wiki is using the TWiki engine (http://twiki.org). The soundtrack is from DJ Cary's Eastern Grooves compilation from Magnatune.com.
