Abracadabra and M-theory

Over at neopets.com, the Lenny Conundrum #100 has already been judged. About 2,000 kids of all ages between 2 years and 90 years divided 10 millions neodollars, so each of us can buy some McDonald's neohamburgers for our cute virtual neopets - or perhaps some neostocks on the virtual stock neomarket or whatever exactly the kids are doing there. :-)

Of course, the answer was "Abracadabra" and everyone who followed my hints could have easily found the answer. This conundrum was much like M-theory. Once you see the logic behind it, you're sure that the answer is absolutely unique. But there are always cynics who never believe the uniqueness. One of them wrote:
  • The problem with fill-in-the-blank problems of these kind is there isn't likely to be a unique solution, if you know what I mean. These kinds of problem involve reading the mind of the problem creator as much as anything else.

When I repeated that the solution is unique and it has as many keystrokes as the number of spacetime dimensions of M-theory, another critic of the uniqueness of the solution - namely Wolfgang Beirl - said:

  • Luboš, but the experimental evidence might still be against your unique solution: An 11-digit number to collect avatars on a webpage for kids? As unique as M-theory??? So it might as well be a random number 8-) There is some evidence on the Net that neopets.com accepted indeed any number for this one ...

I answered his sentence "If it's like M-theory, it might be a random number" by saying that it was doubly wrong: not only it was not random at all, but it was not even a number! :-) You can see how laughable all these abracadabra-skeptics were, and it may be just a matter of time when the experiments show the same about the skeptics concerning string/M-theory! :-)




Incidentally, it was fun to look for the solution. I could not stop. No mathematics or language tricks worked and no web pages gave any useful information. Eventually I went to the other Lenny Conundrums to see how the previous problems looked like - what kind of reasoning can one expect from "Lenny". The problems #1...#8 seemed easier. Suddenly the answer to the problem #9 was 2616. At that moment I exploded because it was clear that it was just a matter of minutes to complete the "theory of everything". ;-)

  1. How many man hours have been wasted on this idiocy? Surely we can come up with a more interesting problem to work on than the internal symmetries of the Lenny conundrum?

  2. About 4 hours if summed together. It was partly a weekend relaxation. If you define your particular projects for us more accurately, it could be more interesting.

  3. String theory is certainly correct, and they are distributing neoNobel neoPrizes on neopets.com to the stringy neophysicists.

  4. The last comment is pretty funny! :-) And eventually, in 50 years or so, children on the 2055 version of neopets.com can really get neoprizes for solving real string theory problems.

  5. Lubos,

    just to set the record straight. You used initially the
    wrong number #99 instead of #100.
    The confusing results I retrieved with google using your
    input were in part responsible for my 'random number' comment.

    Indeed we submitted the correct answer, once my daughter
    Diana opened her neopets account. In my opinion, a neopets
    account was the main ingredient to answer #100, just
    like experimental evidence for supersymmetry will be the
    main ingredient to answer the quantum gravity conundrum
    (one way or another) ...

    Thank you again for drawing my intention to this and special
    thanks from Diana for the neopoints.

    You are the greatest,
    Wolfgang Beirl

  6. Dear Wolfgang,

    thanks for your comment. But: when I was asked the question, I neither had a neopets.com account, nor I knew that this website existed.

    It may be funny if you blame Google for your wrong deductions, but Google is just a tool - and the Google Corporation was not foolish to say that M-theory or Abracadabra was ambiguous. It was you who made the laughable conclusions - so don't blame our friends at Google. ;-)

    And greetings for Diana.

    All the best
    Lubos

  7. Lubos,

    I did not blame anybody, except mentioned that you
    had your numbers wrong initially ...

    By the way you may have asked the question without
    a neopets account but it was certainly helpful for
    the answer.
    As far as I recall, I was the first to post that
    Lenny was from neopets (and yes I did use google
    to find this.)
    And again, the whole episode just shows
    1) that you need 'experimental evidence' for this kind
    of sophisticated (!) problem.
    2) that the paths to the answer can be filled with
    misleading numbers, hints and mis-understandings.

    By the way, congratulations to the neo-Nobel !

    Best,
    Wolfgang

    PS: I will not follow up more, since I really need to
    work today 8-)

  9. What? Abracadabra isn't even a number!

  10. 2616, 3, 11, 10850, abracadabra, 25, 2038

    I'm still scratching my head.

    Lenny Conundrum is a weekly puzzle that appears on neopet.com.
    The answers to the 9th, 16th, 25th, 36th, 49th, 64th, 81st and 100th
    Lenny's puzzles are 2616, 3, 11, 10850, abracadabra, 25, 2038
    and abracadabra respectively. The 100th puzzle was fill in the missing
    value in the sequence
    2616, 3, 11, 10850, ______, 25, 2038.

  12. That only confirms my point about reading the puzzle creator's mind!

  13. If string theory is really anything like this "conundrum", I can only say the Creator's mind is perverse. :)

  14. Well, it's like those SAT and other exams like qualifying exams which test for among other things whether or not a student has studied previous exams, isn't it?

  15. By the way, the new conundrum #101 is about good, old gravity
    and not some M-theoretic abracadabra 8-)
