The Elegant Universe, Now Available Online

Photon Ghoul writes "PBS has made available online all three hours of the NOVA program on unified theory. Formats are QuickTime and RealVideo with each hour broken up into eight chapters each." I watched the whole thing, and while it's clearly for a lay audience (no math required), it was fun and informative. I was pleased to note that dissenting views on whether string theory was science were presented, and even brief discussion of what constitutes science.

      Actually it's closer to $.10 these days. Anyone paying $1-$5 is getting ripped off big time.

      It depends on what *exactly* you are paying for.

      It costs less than $0.10 to produce a can of soda in volume. Yet most people routinely pay $0.50, $0.75, even $1.00 or more for it. Why?

      Because it's not the can of soda you're paying for - it's the convenience of delivery. It's there, in your local store, just around the corner from your office, home, or wherever you like to shop.

      You're not going to run across town because you can save $0.88 on your next 6-pack of soda. For little guys, convenience is routinely a much larger part of the equation than price per unit.

      If you are a smaller ISV, (Independent Service Provider, in case you didn't know) convenience is *far* more important than cost per GB.

      I'm *happy* to pay $1-3 per GB, if the next DDoS attack is filtered out by a qualified network technician in the hosting facility while I peacefully sleep. I'm *happy* to pay this price if there's somebody there, day or night, to help me when something goes wrong. I'm not at all hesitant to pay this if I know that I can handle any reasonable traffic spike, anytime, day or night, without having to buy new hubs, switches, and routers.

      On the other hand, if I was /., and had to deliver a truly massive quantity of traffic every day, the metrics of the business equation suddenly change rather dramatically in favor of price/unit. If you deliver 70 GB per hour instead of 200 GB per month, things become quite different quite quickly.

      A good price can be *alot* more than just calculating price per unit, particularly when the unit count is small. Just remember what you are *really* paying for.

At the time, I was truly impressed with Prof. Michio Kaku's elequent and penatrating writing style. As far as books on physics goes, my opinion is that his is a head and shoulder above Stephen Hawkings "A Brief History of Time". Unlike Hawking's tome, "Hyperspace" at times reads like a well written novel with an evolving plotline and compeling characters that put a human dimension on our quest for understanding reality.

      That all fell apart a few weeks ago when I came across an archived broadcast on the webpage of the NPR radio show "Science Friday".

      http://www.sciencefriday.com/pages/1997/Sep/hour2_ 090597.html

      Kaku was a guest on a discussion of the safety of Radio-isotope Thermal Generators (RTGs) which coincide with the launch of the much delayed Cassini mission to Saturn. The voice I heard completely floored me with his arrogance and condescension. He spoke about "saving science from the misguided hands of NASA" as a politician who has no appreciation of the hard work NASA engineers have accomplished would. He verbally assulted another science guest on the show as a "fringe" with no qualifications.

      This sounded nothing like the voice of knowledge and wisdom I had come to know in the pages of "Hyperspace". Surely Mr. Kaku must be just having a bad day?

I can go on about exactly how he leaves us short for many more paragraphs. But I'm off topic as it is so I'll let you pursue that at your own discression.

But, some day the work that I do, along with many other mathematicians will provide the foundation, the pure science, which physics will be able to use for experimental understanding. Without pure scientific understanding, experimentation can never be anything more than observation.

      What 'string theory' should be more properly stated as is 'string hypothesis'. It is certainly not yet a true theory and it is certainly not yet a law. Currently, it is purely a hypothetical explanation and possible prediction model. That does not make it any less powerful or less important. Some day it may prove to be the 'bridge' that is needed to complete one more piece or pieces of the grand puzzle. Although, alone it does not need to be experimentally verifiable.

That is, math is simply about pure mental constructions, and doesn't necessarily have any connection to the "outside world" or "reality".

      As a fan of math myself (I am currently playing with non-well-founded axiomatic set theory), it irks me when people claim that math is a science, or has applications as its purpose. Similarly, it is bothersome when people bring religious concepts such as the Platonic Realm into math.

      The very intent of math is to have certainty, not faith in the external existence of mathematical objects - somehow independent and trancendental apart from our minds.

      Who knows, maybe these theories do exist independently from our thought, but we can't confirm this. However, we can confirm our own thought's existence, and therefore math should be founded on such a thing.

      String Theory is either a religion or philosophy in that it makes a claim about reality based on nothing other than faith. It is just as valid a science as creationism. I do find String Theory to be more interesting though as it makes use of interesting math :)

    They are trying to keep people interested, and special effects and exciting narrative help with that.

    I think that the fact that they had to pack so many effects into the show to keep today's audience interested is mainly a reflection of the sad state of the MTV generation's attention span.

    Actually, I was fine with the visual effects that demonstrated the physics priniciples. Computer graphics are available; why not use them. What stood out to me was the need to keep something, anything moving on the screen at all times. Thus, all the strange sliding panels contantly shuffling back and forth in the background behind the various extra-smart scientists as they talked.

    The producers must have reasoned that the target audience was so used to being fed spinning logos, scrolling textbars, subsecond edit cuts and webpage-like clutter, that if they saw nothing but someone sitting still talking, then they'd assume the TV must somehow be broken.

    "The Elegant Universe" is about string theory, sure... but rather than being as accurate and descriptive as possible, they opt to squander three hours on needless (and logically irrelevant) special effects.

    I found not only the special effects distracting and annoying but even the flashy way they filmed non-SPFX scenes. They even tried to do funny things with the editing of the interviews with the professors!

    I happen to know one of the string theorists who appeared on the show. I was talking with him about what he thought of the finished product a few days after the final episode was shown. Both he and I agreed that while the rapid-fire editing and SPFX were not to our liking, we were both impressed that someone at least spent a fair chunk of dough to make this show. And he told me that he was hearing that a lot of kids (I assume he meant younger kids -- not college students) liked the show and that it got them interested in string theory.

    We could certainly debate whether those kids actually learned anything or whether they were just dazzled by the pretty pictures but I have to say that it's been quite awhile since anyone put up a chunk of dough to make a program about science. The show may not have been to my liking but if it can at least make people think that we're doing interesting and exciting stuff, perhaps it does serve an important purpose. I guess it all comes down to who their target audience is. And with Nova these days, one can never really be sure.

  35. No explanaiton of equal red-shift by pauljlucas · · Score: 2, Insightful
    In Carl Sagan's "Cosmos," an explanation was given as why it should be the case that we observe objects in space all red-shifted equally in every direction. The theory presented was that our 3-physical dimension universe was warped into a 4th physical dimension like a sphere. We (our galaxy), along with every other galaxy, is on the "surface" of this hypersphere. As the universe expands (much like blowing air into a balloon), the "surface" area of the hypersphere increases. Every point on the "surface" is equal to every other and all are moving away from each other. The "center" of the universe is the center of the hypersphere and does not exist within what we know of as 3-dimensional "space." With 4 space dimensions, "time" is relegated to the 5th.

    However, I've never heard mention of the above theory since, including in "The Elegant Universe" (unless I somehow missed it). Yes, String Theory requires 11 dimensions total, but (apparantly) all of the 7 "extra" dimensions beyond the 3-phsycical and 1-time dimensions are "all curled up" and very small. In contrast, the 4th-physical dimension mentioned in "Cosmos" is the size of the entire universe.

    So the question is: is the theory of the 4th-physical dimension and the "hypershpere universe" as presented in "Cosmos" still believed to be true?

      The analogy between expansion of the universe and expansion of a balloon is just that, an analogy. Just like all analogies in physics, it breaks down if you push it too far.

      Space-time is 4-dimensional, but curved in such a way that it is not possible to embed the curved 4-D space-time into a flat 5-D space - or even a flat space of any finite dimension.

      For an example, take a one-dimensional piece of string. Now I can curve this into something that can be embedded in two dimensions (say, by wrapping it into a circle), but I can also curve it in a way that cannot be embedded in two dimensions. ie, as well as curving it along a plane, curve it out of the plane, as in a ball of string.

      If you apply an arbitary curve do an N-dimensional surface, you cannot, in general, embed this in N+1 dimensions. In the example of a ball of string, we needed N+2 dimensions. Going further, we could wrap the string around a 4-dimensional hypercube (although that is a little harder to demonstrate;-), and an ant walking along the string will still think its in a 1D universe.

      In summary, it is not meaningful to think of space-time as being 'curved into an extra dimension', except as a very rough first-approximation. Just like the ant walking along a piece of string, you can curve it in much more interesting ways than is allowed by just adding one extra dimension.

      That part of the analogy still holds, but the curvature of space-time is irrelevant to equal red-shift. The universe is expanding uniformly and symmeterically everywhere, and doesn't depend on where in the universe you are observing from.

      For another example, take a piece of pastry of uniform thickness. Put in some rasins in a grid spaced at equal distances. Now roll out the pastry smoothly in all directions. All of the rasins move the same distance from their nearest neighbors, and rasins initally at a distance x are now at a distance K x (here, K is bascally the 'Hubble constant' of the pastry :-).

      The balloon is used because its easier to demonstrate blowing up a balloon versus rolling pastry (scientists are usually not good a cooking!). The curvature of the balloon is irrelevant - and misleading because the whole point is that all points (ahem, no pun intended) in the universe are moving away from all other points - there is no center of the universe, or not one that can be determined by simple red-shift experiments anyway.

      The large-scale curvature of the universe is very nearly zero, so you need to think of the space-time being very nearly flat, and a long way from the boundary. Either a very very large pastry sheet (the edges are beyond the horizon) or a very very large balloon.
