Get ready to re-think your ideas of reality. Join UCSD physicist Kim Griest as he takes you on a fascinating excursion, addressing some of the massive efforts and tantalizing bits of evidence which suggest that what goes on in empty space determines the properties of the three-dimensional existence we know and love, and discusses how that reality may be but the wiggling of strings from other dimensions.

    A better link is at youtube

    BUT

    this lecturer is not recommended – every second word is OK, he drives me mad.
    The info presented is dumbed down so much it does not make sense. He makes silly mistakes in pronunciation and formula.

    Find somewhere else for education.

    I didn’t dislike him as much as SEEKER did. I thought it was a pretty clear explanation of what the Higgs is. He also did a nice job connecting the Higgs with the standard model. I also haven’t heard the topology of curled up dimensions in superstring theory connected with the three groups of particles in the standard model so clearly.

    I liked it. (ok?)

    The production on this one is a bit more rough.

    The speaker needs to learn how to pronounce the word cosmological.

    It’s embarrassing how he repeatedly and frequently he mispronounces it.

    Also, if needs to stop saying “OK” at the end of every other sentence.

    I learned a few things and didn’t find the speaker annoying as others seemed to. This is one of the few occasions when I actually stuck with the theory being presented and I don`t think I am that stupid.

    These invisible fields are a fascinating eye opener to our expending

    knowledge of what constitutes the real world.

    It’s amazing how some people fixate on trivia and miss the big picture. This was a fascinating presentation. I got so interested in the subject I never even noticed the “Flaws” others pointed out- little things for little minds I suppose, Perhaps it was all over their heads and the presenters delivery was all they could understand.

  • keith

    the man obviously has a substantial understanding of the subject he is trying to explain… the key thing to think about is for lack of a better word the “dumbing” down of extremely mathematically and physically complex ideas and formulas… my personal opinion is… all things considered he performed with grace and swiftness and i wish i could relate such intricate details in such a manner…

    stop fighting the opinions of other people… listen with no preconceptions… accept no fact without testing it yourself… be your own teacher…

    Hmm, I’d like to know where empty/vacuum space is in the natural universe because last I checked Stellar and Interstellar space are filled with particles of all kinds. Space is not a true vacuum, a large portion of it is known to be in a plasma state and possibly the majority/all of it is plasma.

    But regardless a vacuum state is quite interesting, where the energy of the universe has no local physical conditions to react to in any way and is thus in a pure energetic state. It most certainly does determine all of the properties of the universe.

    Mr. Griest and I may have different views of how it so but at least in one area we seem to agree on our understanding of it in regards to “it’s place” or role in the universe, sort of.

    Interesting discussion by him no less, worth a review for those interested in science who have an open mind.

      Update 2012.Mr Griest was correct in all his assumptions.Since this doc was made and you commented on your differing views(you never did say what that view was,beyond that you disagreed with him onthe emptiness of space.) On 4 July 2012, the CMS and the ATLAS experimental teams at the Large Hadron Collider independently announced that they each confirmed the formal discovery of a previously unknown boson of mass between 125 and 127 GeV/c2, whose behaviour so far has been consistent with a Higgs boson.

    I thought the lecture was interesting and clear and made a difficult topic understandable . Some commenters complained the material was “dumbed down”. Well, I’m sure it was. Most people are not physicists so some dumbing down to make the topic interesting and accessible to a larger audience makes sense.

    Big Bang or Fairy tale

    Did Big Bang really happened and if it did how how could the galaxies 13 billion years old look on the similar way as those closest to us.

  • brill!

    Just FANTASTIC! i’ve heard many of these ideas form various sources before, but NEVER at once with such a clear concise and understandable grasp of the connectivity of the ideas, just fantastic really great. i’m going to watch it again tomorrow to make sure i understood. what a great overview of the state of play.

    thank you so much.

    Mark, please blink your eyes. :)

    Please forgive me if I overlooked some blairingly obvious detail here, but did he have water as HO2? 3:30

    • LOL

      LOL yeah, I saw that too!  Two oxygen atoms and one hydrogen!

  • Gravedig

    Fantastic documentary. I would be very much an interested layman and have found few speakers who explain the material as concisely or as engaging as Kim Griest.  

  • Anonymous

    and then neutrinos are measured moving faster than light. Elegance?

  • http://none Michael Kinsey

    The Higgs field is time. Huh

    • http://www.facebook.com/mark.mewton Mark Mewton

      Close. The Higgs field causes our consciousness to perceive time and space as a singularity.Perhaps our consciousness IS the Higgs field.

  • Mark Peaty

    I think this is excellent! He managed to put one of the most complex theories created by humans so far into plain English. For those of us who are not trained in higher mathematics he has made the basic ideas of the Standard Model accessible.

    [NB, yes the on-line slide does have the water molecules labelled wrongly. The people at the lecture however saw a corrected version; you can see H2O molecules on the blackboard/screen at the front of the room.]

    This is a semi useless site.After trying 5 broken link docs, this one worked, then stoped after 14 minutes.
