    I knew the guy when I was there.

    Odd coincidence, considering the extensive labour I just posted over on the Bessler thread for the benefit of OC.

    I am not sure that thread benefits anyone.

    It sure isn't benefitting OC, but it could.

    I don't "see" how a monopole magnet could be any more useful than other monopole forces (accelerations?) like gravity. It would be interesting, though.

    Interesting and generally considered not to exist?

    Hmm... Sounds a lot like the contents of some envelopes circulated between property developers and our elected representatives before the property bubble burst here! ... erm allegedly ... in my opinion ... or something!

    There are different kinds of nonexistence:
    -nonexistence by incompatibility with the actual universe (Orbo)
    -nonexistence by convention (women's ages over 35 and weights over 50kg)
    -nonexistence by convenience (red lights when I'm in a hurry)
    -nonexistence by expediency (human rights in Cuba, including Guantanamo)
    -nonexistency by sleight of hand (cheques delivered to elected reps by property developers)

    The remaining fourteen types are left as an exercise for the reader.
  2.  
    -nonexistence by denial (there's no such thing as a PIFU)
    -nonexistence by affirming existence of an antithetical opposite (there's no such thing as life after death, because when you die, you are in fact dead for the duration...)
    -nonexistence by fading away of prior existence (kuru is dying out amongst the Fore of PNG because they no longer feed diseased corpses to their women and children)
    -nonexistence by complacency (there's nothing that can go wrong, I am sitting here fat dumb and happy and the fuel gauge is still on F...just as it's been for the past 4 hours.)

    Ten to go...

    Magnetic monopoles have never been observed but current EM theorey does not explicitly deny their existence.

    Also, IIRC, you can build certain devices that exhibit magnetic monopole like properties on a macroscopic scale.

    Oh I like that one best so far! Many examples spring to mind - "But the popup said click here to remove my malware!", "The local council approved my planning permission application to build in the middle of the known flood plain so I figured it must be ok!", "It was a 15 year old car, and although the air bags had never been serviced the airbag warning light never came on, so I figured it must have been fine!".

    -nonexistence by stubbornness (I say "X". You say "not X because of Y". I say "I'm not convinced Y exists". You go to great lengths to explain why Y exists. You're arguments make sense. However, I don't understand some of them. I don't have any counterarguments. In fact, I'm not qualified enough, experienced enough, skilful enough or articulate enough to understand or even express accurately the reasons why I disagree with you, but I still disagree with you) Sound familiar? ;)

    Nine to go...

    Interim compilation of nonexistence.

    1-nonexistence by incompatibility with the actual universe (Orbo)

    2-nonexistence by convention (women's ages over 35 and weights over 50kg)

    3-nonexistence by convenience (red lights when I'm in a hurry)

    4-nonexistence by expediency (human rights in Cuba, including Guantanamo)

    5-nonexistence by sleight of hand (cheques delivered to elected reps by property developers)

    6-nonexistence by denial (there's no such thing as a PIFU)

    7-nonexistence by affirming existence of an antithetical opposite (there's no such thing as life after death, because when you die, you are in fact dead for the duration...)

    8-nonexistence by fading away of prior existence (kuru is dying out amongst the Fore of PNG because they no longer feed diseased corpses to their women and children)

    9-nonexistence by complacency (there's nothing that can go wrong, I am sitting here fat dumb and happy and the fuel gauge is still on F...just as it's been for the past 4 hours.)

    10-nonexistence by stubbornness (I say "X". You say "not X because of Y". I say "I'm not convinced Y exists". You go to great lengths to explain why Y exists. You're arguments make sense. However, I don't understand some of them. I don't have any counterarguments. In fact, I'm not qualified enough, experienced enough, skilful enough or articulate enough to understand or even express accurately the reasons why I disagree with you, but I still disagree with you. So there.)

    11-nonexistence by fatigue.( I have given you the correct answer over and over for so long now that I forget what it is.)

    12-nonexistence by decree ("I refuse to accept this - Therefore it is not - and woe betide anyone dumb enough to point out that it is!" - Frequently employed in dictatorial regimes and organisations! Examples: Idi Amin, the former boards of directors of many finacial institutions etc.)

    13-nonexistence determined by testing [empirical nonexistence] (e.g. the claimed relationship does not exist based on the results of a DNA paternity test)

    14-nonexistence by GIT; this list does not belong on the list of lists containing 14 examples of nonexistence
  4.  
    I think there may be more than fourteen. High-energy collisions in the newly inaugurated Large Concept Collider have yielded many fragments that may turn out to be fundamental memes of non-existence in their own right.
    For example, several instances of nonexistence by exhaustive search of the problem space have apparently been detected, putting into question the fundamental logical postulate that it is impossible to prove a negative.

    No self referential nonexistences are allowed. Our human brains are not ready.

    Are you referring to geometrical invariant theory or to the Korean film of that name?
