    From BBC: “Brian Cox: ‘Multiverse’ makes sense” 

    BBC

    23 September 2014

    The presenter and physicist Brian Cox says he supports the idea that many universes can exist at the same time.

    The idea may sound far-fetched but the “many worlds” concept is the subject of serious debate among physicists.

    It is a particular interpretation of quantum mechanics – which describes the often counter-intuitive behaviour of energy and matter at small scales.

    Prof Cox made the comments during an interview with Radio 4′s The Life Scientific programme.

    In a famous thought experiment devised by the Austrian physicist Erwin Schrodinger, a cat sealed inside a box can be both alive and dead at the same time. Or any combination of different probabilities of being both dead and alive.

    This is at odds with most common perceptions of the way the world is. And Schrodinger’s experiment was designed to illustrate the problems presented by one version of quantum mechanics known as the Copenhagen interpretation.

    This proposes that when we observe a system, we force it to make a choice. So, for example, when you open the box with Schrodinger’s cat inside, it emerges dead or alive, not both.

    But Prof Cox says the many worlds idea offers a sensible alternative.

    “That there’s an infinite number of universes sounds more complicated than there being one,” Prof Cox told the programme.

    “But actually, it’s a simpler version of quantum mechanics. It’s quantum mechanics without wave function collapse… the idea that by observing something you force a system to make a choice.”

    Accepting the many worlds interpretation of quantum mechanics means also having to accept that things can exist in several states a the same time.

    But this leads to a another question: Why do we perceive only one world, not many?

    A single digital photograph can be made from many different images superimposed on one another. Perhaps the single reality that we perceive is also multi-layered.

    The laws of quantum mechanics describe what happens inside the nucleus of every atom, right down at the level of elementary particles such as quarks, neutrinos, gluons, muons.

    A proton, composed of two up quarks and one down quark. (The color assignment of individual quarks is not important, only that all three colors be present.)

    newtrino
    The first use of a hydrogen bubble chamber to detect neutrinos, on November 13, 1970. A neutrino hit a proton in a hydrogen atom. The collision occurred at the point where three tracks emanate on the right of the photograph.

    gluon
    In Feynman diagrams, emitted gluons are represented as helices. This diagram depicts the annihilation of an electron and positron.

    The weird and wonderful world of quantum mechanics reveals that nature is at heart probabilistic. Nothing can be predicted with any certainty.

    “Everybody agrees about that” says Prof Cox. But where physicists don’t agree is about how these facts should be interpreted.

    For decades, the Copenhagen interpretation of quantum mechanics, which allows for only one universe, dominated particle physics.

    But Brian Cox supports the many worlds interpretation and, he believes, more and more physicists are now subscribing to this view.

    Brian Cox on the LHC 

    Published on Dec 8, 2012

    A great video, a bit dated, by our freind Brian Cox

    “Rock-star physicist” Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging and accessible way, Cox brings us along on a tour of the massive project.

    Watch, enjoy and learn.

    Brian Cox, BBC Wonders of Life 

    It is no secret in these pages that I believe that Brian Cox, Sir Brian Cox, physicist, teacher, TV darling, is the best thing to happen for Basic Science Research ever.

    Brian was the host of The Big Bang Machine about the LHC at CERN, which was featured here.

    Brian also did the BBC produced Wonders of the Solar System, Wonders of the Universe and so far two series of Stargazing.

    Now comes also from the BBC Wonders of Life, Brian’s latest bit of programming. The program is truly a wonder in itself. Pretty much all of the above you can find on YouTube with some searching.

    Here is the first video in Wonders of Life to get you started.

    Brian Cox on Basic Science: “Brian Cox Lecture – GCSE Science brought down to Earth” 

    The great emissary of Science, Dr. Professor Brian Cox, OBE, delivers a fascinating lecture at University of Manchester.

    Brian Cox Head shot

    “Professor Brian Edward Cox, OBE (born 3 March 1968)is a British particle physicist, a Royal Society University Research Fellow, PPARC Advanced Fellow and Professor at the University of Manchester.He is a member of the High Energy Physics group at the University of Manchester, and works on the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, near Geneva, Switzerland. He is working on the R&D project of the FP420 experiment in an international collaboration to upgrade the ATLAS and the CMS experiment by installing additional, smaller detectors at a distance of 420 metres from the interaction points of the main experiments.” (Wikipedia)

    If you are interested in basic science, this video is 1:15 of pure ecstasy delivered by a master.

    Brian Cox Goes Stargazing 

    A friend knew of my affection for Dr. Brian Cox, a.k.a. Sir Brian Cox, OBE.

    bc

    So my friend let me know about a BBC2 series of videos called Stargazing Live.

    There are currently two series of three episodes each. All are available at YouTube.
    I did a preview of this post and saw that the videos are all bunched up, sorry about that, I tried for a wee bit of separation between them, but it did not happen. I did test the videos and they do work.

    If you go to YouTube to find them for yourself, I can tell you that for the Opera broswer and Firefox there are good video downloaders available and that you can get at least 720p on the first series and even 1080p on the second.

    Now, this is first and foremost TV. The project is based at Jodrell Bank Observatory.

    The 76 m Lovell Telescope at Jodrell Bank Observatory managed by the University of Manchester

    The videos are aimed at a popular audience, not scientists. Brian’s partner is the Irish stand-up comedian Dara Ó Briain, who does quite well with the subject matter.

    There are long distance connections to observatories in South Africa and Hawai’i . There is a link up with the International Space Station. And, finally, there are some very special guests, one of whom actually walked on the moon.

    I hope that you enjoy these videos as much as I do.

    So, without further ado:

    Series 1

    Series 2

    The Big Bang Machine – Brian Cox 2008 

    If you are interested in the work of the Large Hadron Collider at CERN, and, if you have not seen this video, consider it my treat. This is the BBC version, all 58 minutes. Not the version shown on the Science Channel in the U.S.A., which lost 13 minutes of footage to commercials.

    This video was produced prior to the start-up of the LHC.

    I hope that you learn from and enjoy the video.

    Combining My Interests: Nico Muhly Should Write Music for Brian Cox’s next “Wonders…” series 

    I maintain two blogs, one on Music, one on Science. This post will appear in each blog.

    Short and sweet.

    Combining my two interests: Nico Muhly
