    Posted By: TrimI have been trying to bully Philip to build me a device based on T rays and heated books and some computer software but he thinks it is daft so even he isn't perfect like me.


    The problem does not lie in the medium. It lies after the interface to your brain.

    Great so you want to take it on, the idea is quite straight forward, heated objects (say 80c) emit T rays, ink and paper should emit them differently.

    So by careful experiment, if necessary a page at a time of different books, it should be possible to build up a data base that a computer could analyse given an initial sample (of the paper and type) and so build a device where books could be digitised and sealed by libraries so that they could lend second hand text books all over the world for cheap E readers.
    The books could be safely sealed away, that should be cheaper than sending second hand books all over.

    Maybe a small remittance could go to the author and publisher.

    I got it the first time. All this unknown technology just to avoid turning pages!

    Why can't you say it is beyond you. All them used books that could be put to good use all over the world.

    Take your development budget. Hire Subsaharan Africans to flip pages. Put the books through scanners. Start now before Google gets the idea.

    Well the least you can do is pay for it as you wimped out of the project.

    Scientists predict time will stop completely


    And then what?

    The experience of moletrap ever since the days of Steorn is that SOON is maximally late. There can be nothing later.

    In the beginning there was nothing ... but before that there was SOON !!!

    After the final Big Crunch there was nothing once again. And after that came SOON !!!

    Help!

    Hawking's 'Escher-verse' could be theory of everything
    - On the face of it,

    the idea that Escher's images can describe the layout of the universe seems to contradict what we know about it.

    The images in question are tessellations, arrangements of repeated shapes, such as the images of interlocking bats and angels seen in Circle Limit IV. Although these are flat, they serve as "projections" of an alternative geometry called hyperbolic space, rather like a flat map of the world is a projection of a globe. For example, although the bats in the flat projection appear to shrink at an exponential rate at the edges, in hyperbolic space they are all the same size. These distortions in the projection arise because hyperbolic space cannot lie flat. Instead, it resembles a twisting, wiggly landscape of saddle-like hills.

    That is not what our universe seems to look like. Measurements of the cosmic microwave background - the echo of the big bang - and distances to supernovae have revealed that our universe is flat, not twisted.

    It is also expanding at an accelerating rate, because of a mysterious entity known as dark energy. We don't know what dark energy is or where it came from, but the mathematical language provided by Einstein's theory of general relativity has a way to describe this accelerated expansion. Sticking a constant - known as the cosmological constant - into the general-relativity equations keeps the universe expanding forever, but only if the constant has a positive sign. Until now, saying we live in an ever-expanding universe has been the same as saying our universe has a positive cosmological constant.

    There are some outstanding problems, however. General relativity covers this aspect of the universe, but it can't describe the big bang. Nor can it unite gravity, which works on large scales, with quantum mechanics, which works on very small scales. "That means you cannot predict why we live in the universe that we live in," Hertog says.

    String theory, in the meantime, offers a beautifully complete picture of the universe's history and connects gravity to quantum mechanics - but is most comfortable in a universe with a negatively curved, Escher-like geometry and with a negative cosmological constant.

    This left physicists with a deep chasm to cross: on one side is a universe that works but lacks a complete theory, and on the other is a complete theory that doesn't describe the actual universe.

    Now, Hawking, Hertog and James Hartle of the University of California, Santa Barbara, are proposing a bridge. They have found a way to produce expanding, accelerating universes using a negative cosmological constant. This means that string theory may, after all, describe the universe that we observe. The proposal grew from an idea that Hawking and Hartle had in the 1980s to get around general relativity's shortcomings by looking for a quantum picture of cosmology.
