What I found on Wikipedia today

Posted by John Quiggin

In mathematics, the monster Lie algebra is an infinite dimensional generalized Kac-Moody algebra acted on by the monster group, that was used to prove the monstrous moonshine conjectures.

I reached this in six or seven steps from Political correctness. Like to guess my route? As a hint the first step is in the lead section.

  1. Using only links in the lead, I managed to get from Political correctness—> Straw man—> informal fallacy—> mathematical logic, but I’m having trouble getting anywhere near group theory in the requisite number of steps, so I’m beginning to think it requires a mathematician who worked in both areas and links in the body of the article.

  2. Political Correctness → Regnery → University of Chicago → Bertrand Russell might be a good start. That leaves you 3 more links to get from Russell to Monster Lie Algebra.

  3. I’m so terribly bored:
    source
    Straw man
    quote mining
    creationists
    age of the earth
    numerology
    Hermann Weyl
    Weyl character formula
    destination

  4. At the other end we clearly want something which links to Monster Group → Monster Lie Algebra.

  5. identity group (Wikipedia Search), then links:
    => group (mathematics)
    => group theory
    => Monster group
    => monster Lie algebra
    => Lie groups
    => Kac-Moody algebra

  6. On the other hand the Lie Algebra gets its “monster” name from the group, and the group is finite. But fairly large, for something so shapely.

  7. Political correctness -> pejorative -> redneck -> moonshine -> moonshine (disambiguation) -> monstrous moonshine -> monster group

  8. Very good, onymous, but my route started with “straw man”

  9. Political correctness
    Straw Man
    Proof by Exhaustion
    Classification of Finite Simple Groups
    Group Theory (category)
    Moonshine Theory (category)
    Monster Lie Algebra

    Any good?

  10. Damnit, you beat me.

    Although mine was:

    Straw Man
    Proof by exhaustion
    Classification of finite simple groups
    Monster Group
    Monster Lie algebra

    … once you’ve gotten to simple groups, though, there must be hundreds of ways to get to the destination.

  11. Also, when I saw the first paragraph in my RSS reader, I assumed you were noting new wikipedia vandalism (since you’ve posted on the subject in the past. I note that your old find is now missing some images).

  12. Exactly right at #7 Justin, but the vandalism post was by John H.

    Update: Actually, I should have said “very close”, #10 is a bit closer. But, as noted there, it’s PC-FSG that is the difficult bit.

  13. I don’t believe you.

  14. but the vandalism post was by John H.

    Thinking that all Johns are the same is often due to a misunderstanding of the J-invariant… which is, of course, linked to from the Monster Lie Algebra page.

  15. Without looking at the others:

    University of Chicago
    Andre Weil
    Theta Function
    Modular Form
    j Invariant
    Moonshine Theory
    Monster Group
    Monster Lie Algebra

    This should be able to be shortened a great deal; you are already in the right neighborhood with Weil, and once you get to modular forms you should be home free.

  16. Please colleagues, not too many math jokes. People already think we are strange! Thanks.

  17. Too late christian, too late.

  18. already posted this comment at the secret blogging seminar, but:
    5 clicks:

    0. Political correctness
    1. University of Michigan
    2. Fields Medal
    3. Richard Borcherds
    4. Monster group
    5. Monster Lie algebra

  19. The key link here is Ann Coulter:

    This online forum in the Nashville Tennessean has the terms “monster lie” and “political correctness.” Never mind that “monster lie” in that context doesn’t refer to monster lie algebras. Oh, well, at least Ann Coulter is good for something.

  20. Please colleagues, not too many math jokes.

    Oh, you’re one to talk, christian h. Surely you wouldn’t expect this group to let sleeping dogs Lie. You’re not that simple.

  21. Sorry guys, having a bad day. Too much Winter here in Chicago, the jokes are quasi-thin on the ground.

  22. Man, my face is red—confusing Holbo and Quiggin. I swear I know the difference! I suppose your sensibilities just converged here.

  23. WikiPedia’s rich links don’t help my already gnat-like attention span any….

  24. Christian is not simple, he’s semisimple—his ideals are more complex than ours, and the form of our comments is Killing him. It’s really exceptional.

  25. Obviously; we need an OracleofBacon.org tool, generalized to any start and endpoints in Wikipedia

  26. Actually, I just wrote such a tool, allowing you to find chains between arbitrary endpoints. It requires that you download a rather large file, and then decompress it to an even bigger file, so everything can be done locally—don’t even bother if you don’t have 8GB going spare on your hard drive.

    More information, and instructions, are over on a comment thread at the Secret Blogging Seminar.
