    Hi,

    Found something about Sub atomic particles and wondered if the impossible could be achieved. Now i know that electrons repel one another and that the theory of us touching something such as a cup means we are not really touching it since the electrons repel each other. But what i want to know is what happens when we cut something like a business card? Could it be possible to repair the electrons or 'attach' them back together so the business card can be formed back to its original shape?

    By definition the impossible cannot be achieved. You must have something else in mind.

    I don't see why not. Just don't excepct to accomplish this expecting that "the same" molecules get put ack to their original position.

    So are you saying that molecules could be inserted into the other half of the business card microscopically and then the chopped business card gets placed back to normal? If they can be 'attached' to a string of molecules on the card so that the original string of molecules that was cut in half could be restored, would that mean the business card i've cut in half be restored as though no cut was ever made on the business card?

    From what i know, sub-atomic particles don't get destroyed as they are only added with other sub atomic particles or float individually. So in this case it can be true.

    When you cut or tear a card (or other object), you are breaking bonds between atoms, not splitting atoms, so subatomic particles are not directly involved.

    can you explain what you mean by 'breaking bonds' please? As far as i know, Atoms have sub atomic articles in it (electrons, protons, neutrons) so when you're talking about splitting atoms you're talking about taking out electrons/protons/neutrons. But breaking bonds is something i don't understand. If you break the bond, doesn't it mean you can repair the bond back to its original?

    If you tear the card, you're breaking the bonds between atoms to atoms- not breaking apart atoms. All the atoms remain intact after you tear the card.

    Hi Neverfly.

    I understand now. But doesn't that mean you could attach new atoms to the cut up card so then it can be made new again or 'repaired'? Since atoms taht bonded can be broken, i was thinking maybe they could be repaired since the atoms were not split up. Possibly attract the atoms or something back onto the card...

    I don't know the answer to that one. Perhaps in the future, that will be a method of repair. I'm fairly sure that nothing in physics prevents it.

    But for the technical and mechanical know how to make it happen... wait a hundred years and ask someone else.

    Indeed, as far as I know there is no physical law or established theory suggesting that such a process could not be done - however, one would need technology with the ability to move atoms precisely to the picometre and you'd also need a lot of patience. It would be far more logical, and cost effective, to simply not cut the business card in the first place - or just print out a new one!

    I was actually thinking of engineering and medical uses... Makes it cost effective.

    How many professors out there do you think knows something like this? I mean if we could develop soemthing like this it would be very beneficial for everyone and lucrative market.

    Of course, of course - I jest! Such a process would surely be extremely beneficial, obviously, however it seems rather far off and not very cost effective at this present time anyway even if we could perform such a task crudely.

    It's most probably being worked on anyway. Consider- you don't see results til results are ready.
    At U.T. Austin, there's a project working on a ceramic based superconductor that operates at room temperature- including a hot day.
    It's a work in progress. But you won't hear much about it unless they have verifiable results.

    But imagine what that will do for wiring and electrical supply across the world? swooosh... if they succeed, those guys will be billionaires.

    I'm sure that if it was a currently feasible technique capable of making large sums of money then some corporation(s) somewhere would be doom exactly that - generating vast profits from this technology. However, I do not see such a thing occurring.

    First you have to learn to manipulate single atoms.

    You know, if there was a simple tool which allowed me to manipulate a single atom from the air then this would be so much more fun lol I would be manipulating atoms all day long just to see the outcome.
