  1. granpa, thanks for the subjects, Im still reading them as I write them.

     

    Qoueted from wikepedia on logic programming;

    If B1 and … and Bn then H

    treats the implications as goal-reduction procedures:

     

    to show/solve H, show/solve B1 and … and Bn.

    For example, it treats the implication:

     

    If you press the alarm signal button,

    then you alert the driver of the train of a possible emergency

    as the procedure:

     

    To alert the driver of the train of a possible emergency,

    press the alarm signal button.

     

    My question is, Is that actually how our brains work? Do our nuerons form algorithms in order for us to remember events and have commands tagged with them?

  2. There has actually been like 3 other threads regarding very similiar assignments, wich, in my opinion, Is quite strange due to the relatevelly different means of achieving kinetic energy. You can check them out too, for extra info. {search at the top}

     

    How big would this thing be? Sorry if you already said it, I just skimmed over it, but would something with 2 ski paddle looking things on the sides, and then have the mousetraps move them up and in a circle so it progresses the device forward work? {sorry I cant find a pic to help out, I know that similiar designs were used for early moon rover ideas}

     

    Good luck.

  3. I know our brain Is the one that processese all info that we take in, so in that sense it is, but, surely, the brain does not have a whole bunch of transistor like devices making up processer unites do they?

     

    Im not really sure how the brain takes in info and decides what to do with it, has nueroscience found out yet? What has it found out about the brain?

     

    If I understand right, CPU's work on algorithms and logic gates{ wich I really dont understand, I just read about on a website}[like to though], And that is how we make things like robots and computers{right}?

     

    but, our brains do not work the same way, do they? instead of doing every calculation to find something out, we kind of do a more educated guess and check method dont we?

     

    Has anyone found out how this works?

     

    I just do not know about any of this stuff and would like to.

     

    thanks.

  4. It's the price of a high metabolism. Basic cellular metabolism produces by-products which damage DNA, and because we're so turbo-charged (our basal metabolic rate is about 10x that of a reptile of the same mass) we produce a LOT more of these DNA-damaging by-products. Thus, in order to prevent us from dying of cancer, we had to lose a variety of useful traits, like telomerase and regeneration.

     

    Is that why caloric restriction helps with mice and possibly us?

     

    hmm. I had no idea.

     

    So with a higher excersize lifestyle your to have a higher metablosim, and with a higher metabolism, your to have a shorter life? Is It actually bad to be working out?

     

    Oh. no.

  5. but the electron does pass on...if it does not you have no current flow and the electron does not leave the atom...therefore no ion either way.

     

    Yes, It passes on, but what replaces It? The Electromagnetic induction pushes those already existing in the conductor being used, but that means that It would have to supply electrons to keep the flow going doesnt it? Where do these electrons come from?

     

    Im sorry If I am just asking the same question over again.

     

    no, that is not right. If the battery contained an excess of electrons you could simply connect only the positive terminal to get current flow. But since you have to connect both the positive and negative terminals, it is clear the battery does not contain an excess of electrons.

     

    Im sorry, I am kind of new to electronics, What is the difference between the positive side and the negative side of batteries? I thought electrons were just electrons, and they just have the usual negative charge.

     

    Thanks for the help guys.

  6. For an atom to become an ion, it needs to not have an electron. While the induction causes an electron to leave the atom, this electron is immediately replaced by an electron from the next atom. The electron from the next atom is replaced by the electron from the atom next to it...and so forth until we get back to the original electron. Thus atoms do not become ions simply because of an induced current flow.

     

    But what about In the front where the first electron left and there was nothing In front of It to pass an electron on?

     

    Also, when you take those electrons elsewhere{generator connected to a batterie, then the batterie Is charged, disconnected, and taken elsewhere}, then the copper gets a lesser net number of electrons than when It started with, am I right?

     

    If so:

     

    Then how can electricity be continued to be generated using the same materials for an extended amount of time? Electrons surely do not just "pop up" from the energy.

    {please ignore positron and electron generation from lasers and gold, those do not count, as that they would cancel each other out and become energy again and I am not talking about lasers, I am talking about simpler electricity means than that.}

  7. The mitochondria replicates separately from the cell. During mitosis the cytoplasm simply splits up the mitochondria that are in it.

     

    After mitosis and the mitochondria are seperated, do they repair themselves or anything along those lines? Would the cells eventually run out of mitochondria after several mitosis cycles?

     

    Thanks for the info on all this stuff. I would love to have the pdf file, but my computer seems uncooperative with pdf files for some reason and I can never open them up. Is it available on the web anywhere?

     

    Thanks.

  8. Hello, I came up with the idea of a space elevator being, instead of Konstantins original idea of a straight one,{lse},It Is curved outward and away from earth. In the shape of a sideways j.

    Obviously the chord would be rooted to the ground, and with a little "push" to launch a load off and get going, it would get into space using earths revoloutions. It would work right?

     

    getting back, you would just have to go faster than the chord Is spinning due to earths revoloutions right? Not that fast. Less energy overall? Is this good?

     

    Thanks.

  9. They did It on Mythbusters and said It was not true.

     

    Here Is the link.

     

     

    Although to me, It actually does seem logical. The air pressure from the ball goes In and pushes the little bars In the lock up to the top. Though I think It Is not just the top part that the bars need to go Up to, Its a set spot that "only the key knows", though, I do not know that much about locks, so I can be totally wrong.

  10. I know that torpedos use compressed air for propulsion sometimes.

     

    There is also compressed air cars, but they use the compressed air to push their pistons rather than propulsion itself.

     

    Compressed air Is usually much heavier than gasoline or electric fans, though I definetly think that It Is possible and that you should build it. Why not.
