    Almost all these things are feasible with WiFi.

    The point is, all these things require an infrastructure, which most telcos already have.
    Billing, identification, certification, trust relationships, locationing (sp?), micropayment and the like.

    Actually, in some countries, people have already adapted the mobile as a method of billing, for exactly those reasons.

    For WiFi, companies have to agree upon several standards for those things. And I don't see this happen anytime soon. Especially, when they'll have to compete with a widely accepted system already in place.

    How do you do location based services with WiFi?
    How do you realise payment, how identification?
    How does roaming between different WiFi providers work?
    How do you connect to the mobile partner, considering that IPv6 is still not widely deployed?
    WiFi doesn't work when you move a little bit faster than walking.
    How do you achieve a good WiFi coverage, especially in more rural areas. (Without prohibitive costs)

    Once more, I'd say 3G and WiFi are orthogonal. They serve different needs.

    I think there are some misunderstandings on your side.

    Secondly on the patent:

    Remember, this is Apple, not Bayer or Fuji Photo.
    To quote: "The invention pertains to electronic devices capable of dynamically changing their ornamental or decorative appearance,..."

    They are patenting all these possible future methods including current ones. The current possible lightning is just an example.

    Lastly, on patents (at least U.S. patents, it seams): One can patent almost everything, the question is, will they able to enforce it?
    What should be patentable is the means to do the magic.

    When they develop a coating, which makes it possible to realise this, I find the coating patent-worthy. But not the idea in itself, which is covered by named prior art from Sciffy writers.

    Centrifugal force does "exist". It is a byproduct of being situated in an accelerating system, where Newtons phyics doesn't apply. Prime requisit of Newtons law. You have to be in a inertial reference frame. Well, the laws of physics still apply, you just have to observe it from a stationary system and then transpose it into the accelerated system.

    Calculating in an accelerated system gives you all the non-existant forces or pseudo-forces like centrifugal-force and Coriolis-force.

    OTOH, those forces do not exists as they are only a byproduct of calculating in a rotating frame and not a real force which are the result of exchanging particles like photons, gravitons and the like.

    Speaking of centrifugal force is inaccurate at worst. So, for educational reasons, one should speak of centrifual effect, or Coriolis effect.

    Second law of thermodynamics. AFAIK, the only phyical law with a temporal direction.

    Speaking of cells is a little bit to generic. Let's reduce it the most simple form known to me: bacteria.

    The DNA of bacteria does not age, due to their circular DNA.
    (Human cells have a linear DNA, which shortens at each mitosis, which limits the number of replications -> age)
    They split, so practically they are two identical bacteria (mutations aside) with the same age.
    How do they die? They become defective. It's not like they just stop working out of nothing.

    Why don't they become living again? The same reason a broken glass doesn't get whole again.

    Thinking of cryogenics: It (currently) doesn't work because in the processs of freezing and defreezing cells are destroyed, but there are creatures (IRC, some frogs), which due to the constitution (word?) of their cells, are able to survive this process.

    Let's ignore that the parent was surely refering to the absurdity of SciFi in space in general.

    Assuming that the force is uniform in all directions, there is no reason that the lower density material escapes in planar direction (what tells the material in which plane it has to escape, so to speak).

    My totally uneducated guess is the following:
    Stars rotate around one axis. This angular momentum has to be preserved. If memory serves right a supernova occurs, when the equlibrium of gravitational contraction force and the thermonuclar repulsion force collapses, until a certain pressure is reached which leads to a final explosive fusion process. Now think of figure skating, rotating and a contracting diameter.
    The outmost material will be hurled back into space, the rest contributes to a white dwarf, neutron star, black hole, or whatever.
    But the critical part (for our question at hand) is that the star in it latest moments is not spherical, but eliptical. The material in the rotational plane has a higher momentum, so it will be more likely hurled back into space.

    As I said, this is a fairly uneducated guess. The question is, does the centrifugal force matter anything, considering strength the gravitational force and the thermonuclear explosion?

    Now, it gets interesting. In what context has this been pointed out? Mobile phones, which are another form of wireless access.

    > This means that it is much easier and cheaper to reach a higher percentage of the population with fewer fiber runs.

    The costs of fibre lies not in the length of the fibre, which cost next to nothing compared to the rest of the hardware or the costs to lay the cables, especially in countries, where they have to be run underground (Germany comes to mind).

    But, AFAIK, most industrial countries have already fibre-to-the-hub, and some have partially fibre-to-the-curb. This is necessary for telcos providing DSLs, in order to carry the bandwidth without having to run several hundreds lines of copper.

    How does the lesser population density affect the (assumed) bandwidth barrier of wireless access and the (assumed) constant increase of bandwidth need?

    Note, that the year of Lilienthal's death is also (not coincidentally) the last of his more than 2,000 flights (or glides, if you prefer). Interestingly, in the same year he had completed the construction of a powered glider (compressed CO2).


    To quote different source about the Wright Brothers

    Following in Lilienthal's footsteps, efforts to invent an airplane became commonplace in the 1890's. The majority of the efforts were in Europe, including Captain F. Ferber, Henri Robart, Solirene, Levavasseur, Clement Ader, Percy Pilcher, and Sir Hiram Maxim. In the U.S., prominent attempts were made by Octave Chanute and Samuel Pierpont Langley.


    Wilbur Wright wrote in 1912 that "no one else grasped the basics of human flight as clearly and throughly as he did".
    And I guess, they were not the only ones influenced by his writings.


  19. Re:Next month news: DSL Dropping.... on DSL Rising · · Score: 2

    Wireless has the inherent problem that it is a shared media. The bandwidth you can achieve is therefor divided by the users.

    Next thing, bandwith is limited by the frequency you are using.
    Sadly, there is a practical upper limit for the frequency used, otherwise you'll need a line of sight.

    How can one increase bandwidth? By covering smaller areas. But practically, there is a lower limit. Otherwise, in which ways does the provider differ from a home user with his NAP.

    Then, there is the reglementation of the frequency spectra, which will most surely not vanish, which limits bandwith, too.

    In contrast, increasing the bandwith on wired connections is fairly easy, because of its controllable enviroment.
    There are developments to deploy fibre-to-the-home already.
    My memory is a little vague here, but IRC, in Japan, there is a govermental plan to reach a certain coverage (20% ?) of fibre-to-the-home to a certain date (2005?).

    I may be a little pessimistic, but to me Wireless seams not like a competitor against digital subscriber lines, bandwith wise.

    At best, they complement each other. One providing lots of bandwith, the other high mobility and less hassle. Wireless expanding greatly on the cost of DSL seems unlikely to me.

    And he build small models and real glider out of this data and documented that, too.

    In other words, he did scientific work on aerodynamics.

    The Wright Brothers discovered (probably among other things), that one constant in Lilienthal's formulas was wrong.

    From the The Wright Brothers Page (hardly a page underestimating the work of the Wright Brothers):
