CERN Higgs Boson Discovery Seminar/Lecture

Director General of CERN, Rolf Heuer, and the head scientists from the ATLAS and CMS at CERN in Geneva gives a conference and lecture on the discovery of the Higgs Boson at a rest mass energy of 126.5 GeV at a 4.9 confidence level (the maximum limit being 5) . This confidence level, in experimental physics, constitutes a discovery with 98% probability of certainty, making it the first true discovery of the Higgs Boson in human history. The bump in the energy spectrum observed at 125GeV contained a bump known with 99.9997% certainty. Since the observed Higgs mass lies between 115--130 GeV, this rules out the minimal Standard Model Higgs expected at 141 GeV. This means that it is a Higgs-like Boson! The Higgs seen at 125.5 GeV is at 3.8 sigma confidence level for the 4-lepton channel, the so-called "Golden Channel" of 4-leptons, created by the Higgs decaying into 2 Z-Boson Intermediates and those decaying into 4-leptons, 2-leptons per Z-Boson. These Leptons are Muons, detected by the Compact Muon Solenoid (CMS) detector. The same channel leads to a 3.2 confidence level with the look elsewhere effect taken into account. The Z-boson and photon channel integrated gives 5 sigma, the highest level possible with no significant errors. The W-channel gives 1.5 sigma confidence channel, so it is definitely meeting the double blind trials of a "Well-behaved" Higgs. Its a good boson for a Higgs candidate, it does as the Higgs should. The discovery from the various decay channels detected, the Boson discovered was most likely a "New Boson" or at least a "Higgs-like" Boson at 125.3 +/- 0.6 GeV at 4.9 sigma confidence level. This makes it a significant scientific discovery. The minimalist models of the Standard Model predict that the Higgs mass ought to be at about 141 GeV. So a 125 GeV model is a problem, theoretically, and leads to many problems like an unstable vacuum at energies much lower than the Planck scale. The Physics obtained from this discovery will most likely be new physics that will help us understand electroweak symmetry breaking but it also seems more and more likely that we are beginning to observe the effects of Supersymmetry for the first time aswell. Supersymmetric models are our best bet in this situation for the Boson discovered, for which it behaves like the Higgs Boson should. The Boson Detected with the square root of its action being at 8TeV has a Lagrangian Density of about 5 femtobarns (5 x 10^-9 barns), since 1 barn = 100 femtometers^2 this means the Higgs cross-section is only 5 x 10^-43 meters squared. Experimentally however it is a great triumph and a powerful discovery, the data obtained from this event through rigorous experimental and computational techniques will be studied and scrutinized as normal but now we know where to go from here. The Boson is here to stay and the work is going to begin on mastering it. Considering that it was found in the last energy region searched, this last piece of the jigsaw is deservedly put in its rightful place. The full picture will change everything.

The Higgs Boson

The video is exactly 4:00 - YouTube adds a second. In which Hank takes a few minutes out of his busy vacation to talk about the Higgs boson, the Higgs field, and what they mean. We know a remarkable amount about this universe, but as of this week, we officially know a lot more. It's pretty freaking exciting, and I'm very pleased that our world is still committed to this kind of pure science and discovery. Thanks to Henry Reich of Minute Physics for looking this video over and making sure I'm not totally full of crap.

The Hubble Space Telescope is Back and Better Than Ever!

By popular demand, I've created a high definition montage of the latest images released from the upgraded Hubble Space Telescope. Many Space Fans out there wanted a montage of just the music and animations. Well, your wish is my command. Enjoy the eye candy! The Hubble Space Telescope now has a new Wide Field Camera, a repaired Advanced Camera for Surveys and two new spectrographs, making this telescope into an entirely different instrument than it was before. We have so much to look forward to now; an entirely new generation of images will be pouring out of this thing - what I'm showing here is just the beginning. At first, I was against repairing the HST, I wanted resources put into the James Webb Telescope, I'm glad no one listened to me! All animations/video are courtesy NASA/ESA and can be obtained here: http://www.hubblesite.org/newscenter/archive/releases/2009/25/full/ I purchased the rights to use this music from AudioSparx (thanks for the donations Space Fans, it's what made this possible!) and can be found here: Celtic Dawn: http://www.audiosparx.com/sa/summary/play.cfm/sound_iid.239916 Techno Galactica: http://www.audiosparx.com/sa/summary/play.cfm/sound_iid.277201

The Pendulum and Galileo

Purchase: http://hilaroad.com/video/ Galileo's investigation of the pendulum played a role in the evolution of science. He performed some of the first experiments while discovering the relationship among length, mass and displacement. If you are teaching the scientific method, the pendulum is a good project to start with. Galileo probably gained insight into many issues around motion from his investigation of the pendulum. The video also mentions issues with the church and academia.

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.

Climate Science and Media Distortion - Stephen Schneider

A year in the making, this video pays tribute to a critical scientific and academic figure in postmodern history: Climatologist and Stanford Professor Stephen Schneider. Schneider explains the problems facing the public's understanding of climate change and consequently the lack of action in Washington legislatively. This video was screened before a live audience by Climate One of the Commonwealth Club in San Francisco on Dec 6, 2011 as the introduction to an event honoring Stephen Schneider and presenting an award in his name to Richard Alley, Professor of Geosciences and Associate of the EMS Environment Institute. This video was also partially screened by Ben Santer at the 2011 AGU (American Geophysicists Union) Conference held in San Francisco (http://revkin.tumblr.com/post/14094189165/ben-santer-on-steve-schneider-and-defending) More on Plomomedia: http://www.plomomedia.com More on Climate One: http://www.climate-one.org

CERN News - LHC to run at 4 TeV per beam in 2012

The LHC will run with a beam energy of 4 TeV this year, 0.5 TeV higher than in 2010 and 2011. This decision was taken by CERN management following the annual performance workshop held in Chamonix last week and a report delivered today by the external CERN Machine Advisory Committee (CMAC). It is accompanied by a strategy to optimise LHC running to deliver the maximum possible amount of data in 2012 before the LHC goes into a long shutdown to prepare for higher energy running. The data target for 2012 is 15 inverse femtobarns for ATLAS and CMS, three times higher than in 2011. Bunch spacing in the LHC will remain at 50 nanoseconds.

Thunderbolts the Electric Universe and Plasma Physics

Thunderbolt the Tutorial is about the electrical model of the universe. In the universe plasma makes up 99.99% of everything we can see. Our current model has big flaws that has forced scientist to dream up things that don't exist in order to explain things that we see out there in space. Yet the electrical model can explain most of these things. So why don't we hear about this model? It's not mentioned on TV shows like The Universe or How The Earth Was Made, Discovery Channel, or even PBS, never talk about it, WHY? Electricity, that's why! If the universe has electrical currents flowing thru it, and it does, then it's just a matter of time before we would learn how to harness that energy. You would have to buy a devise that would output the power, but after that it would be free. Imagine being able to drive anywhere you wanted to without having to stop and fill up your tank every 200 or 300 miles. Imagine your home when it's 110 degrees outside, but inside a nice 75 degrees with no electric bill to eat up all your hard earned money. Could it be true? I believe it could, and this would defiantly be a reason for the energy companies to not want this known. _____________________________________________________ Related videos: The truth about dark energy, it's really zero point energy. http://www.youtube.com/watch?v=EqaLSulA_3I A short 10 min video about the electrical universe and plasma physics. http://www.youtube.com/watch?v=gPiGWIf3FjA Dr. Chuck Missler on The Electric Universe 1hr 43min lecture. http://www.youtube.com/watch?v=mxLn06k2ATo Wallace Thornhill on the misconceptions of the electrical universe 13 min. http://www.youtube.com/watch?v=aa9tsMztZPY Universe - The Cosmology Quest Pt 1 http://www.youtube.com/watch?v=L6EGpg_BVBg&feature=channel_video_title Universe - The Cosmology Quest Pt 2 http://www.youtube.com/watch?v=t7uT0JuKT8Q&feature=relmfu ______________________________________ For more informative videos like this one: http://youtube.com/davnxs http://youtube.com/thetruthalwaysaddsup _____________________________________ Now you can add my Playlist to your Channel.

The Universe is a strange place

About the Lecture Perhaps the universe is not so much strange as brimming with lovely paradox. The search for such beauty seems to lie at the heart of Frank Wilczek’s work. Twentieth century physics, from Einstein through Wilczek’s own Nobel Prize-winning efforts, involves demonstrating the existence of a topsy-turvy reality: for instance, that such sub-atomic particles as quarks and gluons, which have little or no mass, “orchestrate themselves into not just protons and neutrons but you and me,” according to Wilczek. “How is it possible to construct heavy objects out of objects that weigh nothing?,” he asks. Only by “creating mass out of pure energy.” These particles are essentially “excitations in otherwise empty space.” Says Wilczek: “That suggests something …beautiful and poetic: the masses of particles are not like, or similar to or metaphorically suggested by—they are the tones or frequencies of vibration patterns in dynamical voids.” The theory of quarks and gluons and the strong interaction accounts quantitatively for “the mass of protons, neutrons and ultimately you and me and everything around us.” But physics has not yet squared away all aspects of the universe. Wilzcek says that “in cosmology, we meet our match, and don’t know what’s going on.” This is because scientists can’t account for much of the mass in the cosmos. 70% of this mass is in “dark energy,” which is pushing the universe apart. Wilczek hopes that explanations for the dark stuff will emerge through improving equations, unifying theories of different interactions and extending their symmetries. “Beautifying equations leads not to ugly consequences but beautiful surprises,” he concludes.

Energy From Thorium: A Nuclear Waste Burning Liquid Salt Thorium Reactor

<http://www.energyfromthorium.com/lftradsrisks.html> _ Successfully developing a liquid-fluoride thorium reactor (LFTR) would essentially solve our planets energy problems for thousands of years, because it would allow us to fully utilize the energy in natural thorium, which makes up 0.0012% of the Earths crust. Most of the research and development work for this technology was done by Oak Ridge National Labs back in the 50s and 60s. They were working to a different set of overall objectives, nevertheless, there are many lessons to be gleaned from their work that can help us to avoid pitfalls and develop LFTR into a high-performance, high-reliability power supply. ___________________ We need to form a consortium to develop a pilot plant to dispose of nuclear waste and generate usable power. Clean the planet to buy the planet!

Liquid Fluoride Thorium Reactor

>http://www.energyfromthorium.com/lftradsrisks.html> _ We need to form a consortium to develop a pilot plant to dispose of nuclear waste and generate usable power. Clean the planet to buy the planet!______________________________ Google Tech Talks November 18, 2008 ABSTRACT Electrical power is, and will increasingly become, the desired form of energy for its convenience, safety, flexibility and applicability. Even future transportation embraces electric cars, trains, and chemical fuel production (jet fuel, hydrogen, etc.) based upon an abundant electrical supply. Although existing energy sources can and should be expanded where practical, no one source has shown to be practical to rapidly fulfill the world's energy requirements effectively. Presently there is an existing source of energy ideally suited to electrical energy production that is not being exploited anywhere in the world today, although its existence and practicality has been know since the earliest days of nuclear science. Thorium is the third source of fission energy and the LFTR is the idealized mechanism to turn this resource into electrical energy. Enough safe, clean energy, globally sustainable for 1000's of years at US standards. This talk is aimed at explaining this thorium energy resource from fundamental physics to today's practical applications. The presentation is sufficient for the non-scientist to grasp the whole subject, but will be intriguing to even classically trained nuclear engineers. By providing the historical context in which the technology was discovered and later developed into a power reactor, the story of thorium's disappearance as an energy source is revealed. But times have changed, and today, thorium energy can be safely exploited in a completely new form of nuclear reactor. The LFTR is unique, having a hot liquid core thus eliminating fuel fabrication costs and the need for a large reactor. It cannot have a nuclear meltdown and is so safe that typical control rods are not required at all. This design topples all the conventional arguments against conventional energy sources in such areas as: * Waste Production * Safety * Proliferation * Capital Costs and Location * Environmental Impact * Social Acceptance * Flexibility * Grid Infrastructure * Efficiency Should America take this step toward a New Era in Nuclear Energy Production? Hear the case for "The Electricity Rock" and then decide. Speaker: Dr. Joe Bonometti Dr. Bonometti has extensive engineering experience in the government, within industry, and in academia over a 25-year career. Recently completing an assignment as the NASA Chair Professor at the Naval Post graduate School, he supported a ship design study that utilized advanced nuclear power derived from thorium. Working at NASA for ten years as a technology manager, lead systems engineer, nuclear specialist, and propulsion researcher, he lead several NASA tiger teams in evaluating the Nuclear System Initiatives fission demonstration vehicle and missions. He managed the Emerging Propulsion Technology Area for in-space systems, the Marshall Air Launch team, as well as a variety of other power and propulsion assignments and is now the Lead Systems Engineer for the Ares I-Y flight. After earning a Doctorate degree in Mechanical Engineering from University of Alabama in Huntsville, he spent several years as a Research Scientist & Senior Research Engineer at the UAH Propulsion Research Center where he served as a Principal Investigator and manager for the Solar Thermal Laboratory. He has worked as a Senior Mechanical Designer at Pratt & Whitney supporting aircraft engine manufacturing and at the Lawrence Livermore National Laboratory within the laser fusion program. A graduate from the United States Military Academy, at West Point, where he studied nuclear physics and engineering, Dr. Bonometti served as an officer in the United States Army Corps of Engineers; both in combat and district engineering management assignments. He is a Registered Professional Engineer in the State of Virginia, and has authored numerous aerospace technical publications, particularly propulsion and space systems technologies. His technical expertise includes nuclear engineering, specialized mechanical & materials research, space plasmas & propulsion, thermodynamics, heat transfer, and space systems engineering. This Google Tech Talk was hosted by Boris Debic.

God Does NOT exist

that which consists of either matter or energy. Therefore if a god exists, it must be composed of either matter or energy. The opposite must also be true. If a god is not composed of matter or energy, then that god, by definition, does not exist. Thus to argue that a god exist, despite a total absence of matter or energy, is to argue, existence equals non-existence, which is a complete contradiction. If a god exists, then physical evidence is really the only methodology by which we can ascertain that a god exists. Of course, this does not require direct physical evidence -- we cannot perceive black holes directly, but we know that they exist due to the effects of their gravity wells on surrounding matter, as well as the flashes of energy that are released as captured matter crosses the event horizon. But since "existence" is defined as that which is composed of matter or energy, the proof of existence must be some evidence of that matter or energy. Evidence is defined as that which impacts our physical senses in some manner, either directly, or through some translating device such as a spectrograph or an oscilloscope. Since our sensory organs are designed to perceive the effects of matter and energy, it is through the evidence of the senses that we can determine the existence or nonexistence of things. If I argue that something exists, but then claim there is no way to detect it, my argument contradicts itself. Let's say I tell a deaf man that I hear a deep, loud sound coming from a speaker. If he lays his hand on it and feels no vibrations, he has every right to be skeptical. If I say that this loud sound does not have vibrations, he may then pull out his trusty microphone or other sound wave detector. If this instrument detects no sound in the vicinity, can I still tell him that this loud sound is occurring? At some point, if my definition of "loud sound" basically boils down to "that which is the opposite of any evidence that a loud sound is occurring," then clearly my approach to truth needs a little work. This approach helps clarify the truth value of the proposition that a god does not exist. If a god exists, then sensual evidence of some sort is required to determine the existence of that god. If a god is not made up of matter or energy, then that god does not exist, since that which is not composed of matter or energy -- does not exist. If a god is made up of matter and energy, then it is subject to physical laws. Since it is bound by physical laws, miracles are impossible, because miracles are, by definition, violations of physical laws. Likewise, a god cannot be all knowing and all-powerful, since both attributes would violate the basic tenets of physical laws. All knowing would require instantaneous knowledge of all matter, past, present and future, which is clearly impossible, while all powerful would require the ability to break the bounds of physical laws, which brings us back to the realm of nonexistence. If a god is subject to physical laws, then praying to a god makes about as much sense as worshiping a black hole, begging the Sun to grant you favors, or circumcising your son to appease the moon. If a god is not subject to physical laws, then the concept of a god is synonymous with the concept of non-existence. Why is there such resistance to the fact that a god does not exist? Many people redefine "God" within their own minds as "a potential form of matter or energy that has not been discovered yet," or "that which could exist in an alternate universe," or something to that effect. However, either a criterion for determining truth exists, or it does not. If such a criterion exists, then it must be objective, and based on the evidence of the senses and reason, which precludes the existence of any deities. If no such criterion exists, then both everything and nothing is true, and agnosticism, atheism, superstition, religion and the belief of the flying spaghetti monster are all equally valid. If an objective criterion for truth exists, then it cannot logically be applied according to whim, or only in situations that feel emotionally comfortable. Through this logical method we can determine no god exists. Actions are more important than beliefs.

2008 Herzberg Lecture

he 2008 Herzberg Lecture took place November 4, 2008 at Carleton University. Rolf-Dieter Heuer has been designated as the next Director General of CERN, the European Organization for Nuclear Research. He has contributed to the study of electron positron interactions, the development of experimental techniques, and the construction of large detector systems. Despite great success, many key questions in particle physics and cosmology are unanswered. In particular, some 95% of the Universe consists of unknown dark matter and dark energy. Particle physics is about to enter the Terascale, providing a deeper understanding of the Universe and possibly dramatically changing our view of the world. With the start-up of the Large Hadron Collider at CERN this year, we expect revolutionary results explaining the origin of matter, unraveling the nature of dark matter and providing glimpses of extra spatial dimensions or grand unification of forces and hints on dark energy.
