    It's actually a problem.

    Parrots get bored. They're intelligent. They like to have new stimulus. If only you could plop them down in front of a TV. Most of our parrots ignore the TV. They like the sound for a little bit, but without the visual, they get bored and go do something like rip off the bottom foot of wallpaper in the bathroom. No, I'm not kidding, and yes, the bird is still alive.

    Only Chauncey watches TV, and he likes Barney and the Teletubbies. Oh, the horror! Pepperberg is trying to create a user interface for a parrot so the bird can surf a "parrot web" (probably a DVD). Screen refresh rates are a problem, as is resolution.

    And yet they always pick up the spear with the same hand. They would hand the spear to a friend in such a way that the spear could be grasped most easily by the proper hand.

    I suspect this is more linguistic than biological. In other words, they would say "I only see a half of piece of cake -- the pink half." They would not say the "left half" but it would be the left half that they would see.

    It would be interesting to see how a person with such a world-view would respond to a brain injury.

    They may not have the verbal constructs, but because the body is bilateral and assymetric, there are internal representations of "left" and "right." How would such a person answer "Which hand do you throw with?"

    My parrots would disagree that "left" and "right" are human concepts. They exhibit "footedness" when they examine objects. They have personal biases with regard to spatial preferences. Footedness in parrots is linked to both species and the individual bird. Chauncey, for example, uses a screwdriver with his right foot or out of the right side of his beak. He's not really that smart; he still doesn't know the difference between straight and phillips.

    The woman learned to rotate the plate. But knowing the cake was still there did not enable her to percieve the cake. Now, I'm going on Minsky's "Society of Mind" here, but think of the brain as being a bundle of subroutines, and subroutines pass information to each other. A segment of the mind invoved with perceiving "left" died in the woman. Even though she was intelligent and could learn to cope with this damage, she could not gain back all of what she lost. I suppose a damaged driver is the closest example on a computer. I've had situations where the computer knew the printer was there, knew the inks were there, but it lost the ability to print blue. For computers, updating the driver is enough to repair the problem. We can't update "drivers" in the human brain, and some of them are hard-wired in.

    The mind is a bizarre creation. We think of ourselves as logical and able to adapt, but anyone with a brain injury or depression understands that our brains lie to us at the best of times, and when something goes wrong, the mind can be downright treacherous.

    "Why not just set up a mirror at the end of the plate?"

    Interesting try, but...

    Try it. Imagine putting a piece of cake with two colors of icing on a plate. With a mirror in back. On the left, the icing is pale blue, on the right it's pink. The cake in the mirror has pale blue on the left and pink on the right. Eat the pink piece. The blue (left) piece is still on the left in both reality and the image.

    Our brains do not work the way we think they do. There's a book, titled "The Man Who Mistook His Wife For a Hat: And Other Clinical Tales." The example of the woman who forgot about "left" is in there, or some other book by Oliver Sacks.

    Being the owner of parrots, I have a question about this:

    Does the concept of "recognizing self by mirror" require the concept of "mirror?" If someone doesn't understand what a mirror does, then they may fail the test but actually be self-aware.

    Brain injury patients teach us that there are circuits in the brain for things we wouldn't expect. A stroke patient lost the concept of "left." She could only eat half of a piece of cake in front of her -- her brain wouldn't recognize the other half. She learned to turn the plate, so that a piece of cake would magically appear! Doing this several times, the cake was essentially consumed.

    If the concept of "left" can be lost, what about concept of "mirror?" A human may be capable of reasoning out that the person in the mirror must be me, but for creatures that are less intelligent, I'm not so sure.

    One of our smarter parrots does not seem to recognize herself in the mirror. She attacks the mirror image. A second parrot seems to understand the concept of "camera." I once connected a video camera directly to the TV and videotaped him -- he began to experiment with moving and watching the parrot on the TV move. All of a sudden, he began to show off and...strut. Ever since then, he shows off for cameras and struts when he sees a photo of himself. He won't strut when he sees a parrot of his own species that is not him. (Note: I don't know if he's cueing on backgrounds to tell if the parrot is him or if he can identify himself.) He's the only parrot in the house that doesn't like anacondas on Animal Planet. Raptors also upset him. Most parrots don't watch TV, the refresh rate is too slow. But somehow he does.

    I'd love to know how Alex the Parrot responds to "Who?" when looking at a mirror. One could start out by positioning the mirror so that someone else is visible, someone Alex could name. Then, by changing the angle of the mirror, have Alex look at Alex.

    Not really, the big change came mainly out of stealing information & ignoring patents (The last one because of differences in laws between countries and some wars). Those two inspired more companies to license their inventions to others so that they at least would earn some money, and set a minimum productprice which due to the license was hopefully equal or higher to what they sold themselves.

    Before science became accepted, people we would now call magicians and alchemists actually made scientific progress. Unfortunately, their secrets were closely guarded and not always passed down. What someone learned by trial and error was lost to the regular community.

    The big change that permitted science to flourish was the willingness to share information. Because the information was shared, progress was not limited to what one person could create.

    The failure to use Open Standards won't send us back to the dark ages. But it will slow progress down as each proprietary standard sets up a roadblock.

    Some things are not improved by scaling. Now, the more facilities doing quality research with proper funding, the sooner fusion will become a reality. Even there, though, scaling can cause problems, like dilution of the talent pool, limits to funding, etc.

    With inertial confinement laser fusion, small pellets of fuel are heated with lasers. Imagine a "tube reactor" (chemical fusion engineering?) where frozen bits of fuel are dropped down a reactor, ignited by lasers as they fall. A working fusion reactor may take on such a shape, giving new meaning to "bit torrent."

  20. Why Gravity Gets Weaker With More Dimensions on Evidence of 6 Dimensions or More? · · Score: 1
    In two dimensions, gravity only has to cover a circle arc. As you go further away from the source of gravity, the line grows longer proportional to the distance, and gravity has to cover more length. It's an inverse law. In three dimensions, gravity has to cover a circle. As you go further away from the source of gravity, the circle grows bigger proportional to the square of the distance, and gravity has to cover more area. It's an inverse square law.

    The pattern continues as the number of dimensions increases. Gravity keeps getting weaker the more dimensions there are, because there's more to cover as distance increases.

    I tried to create a simple explanation of why gravity gets weaker as dimensions increase. You can read it at UnSpace.

    Just because it causes one problem in crickets does not mean it won't cause a different problem in reptiles. For example, if the parasite infests the gut of a lizard and causes minute damage, over time the lizard would not get enough nutrition from it's food.

    Reptile husbandry is incredibly difficult. Enticing animals to eat in the first place is often tricky, and their environmental requirements can be surprisingly complex. Finding out that undiscovered infections cause problems wouldn't surprise me.

    For our pet birds, we've just found out that a treatment for giardia stops feather plucking and mutilation in the lovebirds -- even though the birds do not show up in lab tests as having a giardia infection. The thought is that the values the labs look for is designed for humans, and avian species may be affected at much lower levels.

    I've blogged a peliminary report of our findings at UnSpace.

    The drug does not stop plucking in cockatiels, african greys, and mitred conures.
