Just some of the YouTubes I have watched.
Would have liked Blogger to design a Youtube index feature according to the blogger YouTubes we have highlighted in our own blogs. Also each time one comes to this blog or others, a different Youtube will will be presented for viewing from our favorites?

Reality Tunnel
Certainly do not know who the fellow is in present image(Gregg Braden).....but for now, that is not important. He is not important and his message.....about life.....I am concerned about the science. As I watch the Tibetan Monk there is a question for me about the boundary and the infinite. These same notions of belief about the multiverse too have hidden in them thoughts from a scientific point of view(think of The Fabric of the Cosmos IV) as well as a spiritual perspective as shown in YouTube video above. Put the spiritual wording aside then. What is it we strive to do then about something then greater then ourselves? Is this what we are doing?
Of course I am seeking responsible questions about the nature of reality as they are are very important to me.
So indeed it would have been much easier for me to see the traced pathways of routes that any of us took could become a pathway for another to experience and understand. This is not about "What the Bleep" and the value of the entry of the video above, is something more then what is ascertain by such description of what could have fueled those local universes. What is to become the motivation of what could have progressed from the Big Bang to become the eternal inflation?
Yet can we not say that each of us has their individual pathway of experience is but to know that "such a tunnel" predates and points toward the idea of expression as a viable option to the life unfolding for us. Is it real? What is your motivation for being then if not to have a "driving force for expression?" Your acceptance to participate?
So such a tunnel for expression then becomes a method by which all undergo the process toward us saying something that is real when and only when....or indeed, is it illusory? So we accept "the tunnel as real?" Such a format becomes a method by which such expression for life is "becoming?"

It is nice to see particulate expression from this point of view as well. Thanks Lubos.
History of Supersymmetry to Today
Special Topic of Supersymmetryby Science Watch |
Since the 1980s, if not earlier, supersymmetry has reigned as the best available candidate for physics beyond the standard model. But experimental searches for supersymmetric particles have so far come up empty, only reconfirming the standard model again and again. This leaves supersymmetry a theory of infinite promise and ever more questionable reality. See Link above.

Direct Observation of NU Tau
Although it is Fermi dated(last modified 07/09/2000) it is good to see parts of this progression in LHC? Does Tau Neutrino have it's roots in other places as well? So sometimes it is nice to see this connection for myself.

Lepton
A lepton is an elementary particle and a fundamental constituent of matter.[1] The best known of all leptons is the electron which governs nearly all of chemistry as it is found in atoms and is directly tied to all chemical properties. Two main classes of leptons exist: charged leptons (also known as the electron-like leptons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed.
Lepton
Leptons are involved in several processes such as beta decay.Composition Elementary particle Statistics Fermionic Generation 1st, 2nd, 3rd Interactions Electromagnetism, Gravitation, Weak Symbol l Antiparticle Antilepton (l) Types 6 (electron, electron neutrino, muon, muon neutrino, tau, tau neutrino) Electric charge +1 e, 0 e, −1 e Color charge No Spin 1⁄2
There are six types of leptons, known as flavours, forming three generations.[2] The first generation is the electronic leptons, comprising the electron (e−) and electron neutrino (ν
e); the second is the muonic leptons, comprising the muon (μ−) and muon neutrino (ν
μ); and the third is the tauonic leptons, comprising the tau (τ−) and the tau neutrino (ν
τ). Electrons have the least mass of all the charged leptons. The heavier muons and taus will rapidly change into electrons through a process of particle decay: the transformation from a higher mass state to a lower mass state. Thus electrons are stable and the most common charged lepton in the universe, whereas muons and taus can only be produced in high energy collisions (such as those involving cosmic rays and those carried out in particle accelerators).
Leptons have various intrinsic properties, including electric charge, spin, and mass. Unlike quarks however, leptons are not subject to the strong interaction, but they are subject to the other three fundamental interactions: gravitation, electromagnetism (excluding neutrinos, which are electrically neutral), and the weak interaction. For every lepton flavor there is a corresponding type of antiparticle, known as antilepton, that differs from the lepton only in that some of its properties have equal magnitude but opposite sign. However, according to certain theories, neutrinos may be their own antiparticle, but it is not currently known whether this is the case or not.
The first charged lepton, the electron, was theorized in the mid-19th century by several scientists[3][4][5] and was discovered in 1897 by J. J. Thomson.[6] The next lepton to be observed was the muon, discovered by Carl D. Anderson in 1936, but it was erroneously classified as a meson at the time.[7] After investigation, it was realized that the muon did not have the expected properties of a meson, but rather behaved like an electron, only with higher mass. It took until 1947 for the concept of "leptons" as a family of particle to be proposed.[8] The first neutrino, the electron neutrino, was proposed by Wolfgang Pauli in 1930 to explain certain characteristics of beta decay.[8] It was first observed in the Cowan–Reines neutrino experiment conducted by Clyde Cowan and Frederick Reines in 1956.[8][9] The muon neutrino was discovered in 1962 by Leon M. Lederman, Melvin Schwartz and Jack Steinberger,[10] and the tau discovered between 1974 and 1977 by Martin Lewis Perl and his colleagues from the Stanford Linear Accelerator Center and Lawrence Berkeley National Laboratory.[11] The tau neutrino remained elusive until July 2000, when the DONUT collaboration from Fermilab announced its discovery.[12][13]
Leptons are an important part of the Standard Model. Electrons are one of the components of atoms, alongside protons and neutrons. Exotic atoms with muons and taus instead of electrons can also be synthesized, as well as lepton–antilepton particles such as positronium.

The Body Canvas
Let no one destitute of geometry enter my doors." |
Who would have known about the distinction I had thought only myself could bare the artistic rendition of a thought processes that had unfurled in my own expressive way many others had expressed. Yes I had seen students of science with qualitative formulas tattooed over their body....but it becomes personal when you hold the idea of the Body Canvas to iterate something you believe in. So, for the rest of your life?
See Also: Science Tattoo Emporium
In 2007, Carl Zimmer posed a question on his blog: are scientists hiding tattoos of their science? It turned out that many of them were, and they were willing to share their ink with him and the world. Zimmer has posted hundreds of these images in the years since. In Science Ink, he assembles his favorite images from his blog, along with previously unpublished ones, and writes about the science behind the pictures, and the scientists behind the science. From archaeology to astronomy, from neuroscience to chemistry, Science Ink is a guide to the universe, illustrated on the bodies of scientists. See: Carl Zimmer on Science Ink
So for me it didn't matter anymore, but then I thought how can one remain in anonymity if one helps to identify it's owner(have I really released previous convictions)? So tattooing for me was more about the way in which your tattoo is depicted, then on how beautiful designs can be relabeled, or new ones drawn and located on. The story for me is truly fascinating and I found it so for those not knowing.

Career
Besides his popular science writing, Zimmer also gives frequent lectures, and has been on many radio shows, including National Public Radio's Fresh Air and This American Life. His most recent award was a 2007 prize for science communication[1] from the United States National Academy of Sciences, for his wide-ranging and fascinating coverage of biology and evolution in newspapers, magazines and his internet blog "The Loom". Since 11 November 2009 (episode 35) he is host of the periodic audio podcast Meet the Scientist of the American Society for Microbiology (replacing Merry Buckley).Zimmer received his B.A. in English from Yale University in 1987, and began freelance writing for Natural History magazine. In 1989, Zimmer started at Discover magazine, first as a copy editor and fact checker, eventually becoming a contributing editor.[2]

The OPERA neutrino experiment [1] at the underground Gran Sasso Laboratory (LNGS) was designed to perform the first detection of neutrino oscillations in direct appearance mode in the νμ→ντ channel, the signature being the identification of the τ− lepton created by its charged current (CC) interaction [2].

Prof Anton Zeilinger speaks on quantum physics. at UCT
Thanks to Lubos for putting Youtube Video up.
World-renowned physicist Professor Anton Zeilinger entertained and informed a UCT audience about quantum physics during his Vice-Chancellor's Open Lecture at the University of Cape Town on 25 October. Zeilinger is professor of physics at the University of Vienna, Austria, and director of the Vienna branch of the Institute for Quantum Optics and Quantum Information at the Austrian Academy of Sciences.

Energy Boost From Shock Front
Main Components of CNGS |
A 400 GeV/c proton beam is extracted from the SPS in 10.5 microsecond short pulses of 2.4x1013 protons per pulse. The proton beam is transported through the transfer line TT41 to the CNGS target T40. The target consists of a series of graphite rods, which are cooled by a recirculated helium flow. Secondary pions and kaons of positive charge produced in the target are focused into a parallel beam by a system of two pulsed magnetic lenses, called horn and reflector. A 1 km long evacuated decay pipe allows the pions and kaons to decay into their daughter particles - of interest here is mainly the decay into muon-neutrinos and muons. The remaining hadrons (protons, pions, kaons) are absorbed in an iron beam dump with a graphite core. The muons are monitored in two sets of detectors downstream of the dump. Further downstream, the muons are absorbed in the rock while the neutrinos continue their travel towards Gran Sasso.microsecond short pulses of 2.4x1013 protons perFor me it has been an interesting journey in trying to understand the full context of a event in space sending information through out the cosmos in ways that are not limited to the matter configurations that would affect signals of those events.
In astrophysics, the most widely discussed mechanism of particle acceleration is the first-order Fermi process operating at collisionless shocks. It is based on the idea that particles undergo stochastic elastic scatterings both upstream and downstream of the shock front. This causes particles to wander across the shock repeatedly. On each crossing, they receive an energy boost as a result of the relative motion of the upstream and downstream plasmas. At non-relativistic shocks, scattering causes particles to diffuse in space, and the mechanism, termed "diffusive shock acceleration," is widely thought to be responsible for the acceleration of cosmic rays in supernova remnants. At relativistic shocks, the transport process is not spatial diffusion, but the first-order Fermi mechanism operates nevertheless (for reviews, see Kirk & Duffy 1999; Hillas 2005). In fact, the first ab initio demonstrations of this process using particle-in-cell (PIC) simulations have recently been presented for the relativistic case (Spitkovsky 2008b; Martins et al. 2009; Sironi & Spitkovsky 2009).Several factors, such as the lifetime of the shock front or its spatial extent, can limit the energy to which particles can be accelerated in this process. However, even in the absence of these, acceleration will ultimately cease when the radiative energy losses that are inevitably associated with the scattering process overwhelm the energy gains obtained upon crossing the shock. Exactly when this happens depends on the details of the scattering process. See: RADIATIVE SIGNATURES OF RELATIVISTIC SHOCKS
So in soliton expressions while trying to find such an example here in the blog does not seem to be offering itself in the animations of the boat traveling down the channel we are so familiar with that for me this was the idea of the experimental processes unfolding at LHC. The collision point creates shock waves\particle sprays as Jets?
Soliton
In mathematics and physics, a soliton is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed. Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium. (The term "dispersive effects" refers to a property of certain systems where the speed of the waves varies according to frequency.) Solitons arise as the solutions of a widespread class of weakly nonlinear dispersive partial differential equations describing physical systems. The soliton phenomenon was first described by John Scott Russell (1808–1882) who observed a solitary wave in the Union Canal in Scotland. He reproduced the phenomenon in a wave tank and named it the "Wave of Translation".
So in a sense the shock front\horn for me in respect of Gran Sasso is the idea that such a front becomes a dispersive element in medium expression of earth to know that such densities in earth have a means by which we can measure relativist interpretations as assign toward density determinations in the earth. Yet, there are things not held to this distinction so know that they move on past such targets so as to show cosmological considerations are just as relevant today as they are while we set up the experimental avenues toward identifying this relationship here on earth.
For more than a decade, scientists have seen evidence that the three known types of neutrinos can morph into each other. Experiments have found that muon neutrinos disappear, with some of the best measurements provided by the MINOS experiment. Scientists think that a large fraction of these muon neutrinos transform into tau neutrinos, which so far have been very hard to detect, and they suspect that a tiny fraction transform into electron neutrinos. See: Fermilab experiment weighs in on neutrino mystery
When looking out at the universe such perspective do not hold relevant for those not looking past the real toward the abstract? To understand the distance measure of binary star of Taylor and Hulse, such signals need to be understood in relation to what is transmitted out into the cosmos? How are we measuring that distance? For some who are even more abstractedly gifted they may see the waves generated in gravitational expression. So this becomes a means which which to ask if the binary stars are getting closer then how is this distance measured? You see?
