    Since no one objected to my offer, I started a stub for the Kochen-Specker theorem and will continue working on it a bit later.

    OK, I’ve got a more detailed entry up that includes the basic Kochen-Specker theorem. I have not added Isham’s sheaf-theoretic interpretation yet but any comments or corrections on the understandability/correctness/etc. of the standard version I put up would be much appreciated.

    Added Isham's sheaf-theoretic interpretation and changed my original description of the non-categorical version of KS to better flow with Isham's sheaf-theoretic description. I want to make sure the entry is understandable and makes sense the way it is written so any and all proofing and comments would be greatly appreciated.

    Maybe if you have time you could add the missing links to the main actors here, Kochen, Specker, isham, Butterfield, etc. See how we usually do entries on people. Take, say the page Dan Dugger as a template.

    For dead people, in lieu of their personal website, can I link to their entry (if it exists) on the MacTutor website? (I will admit bias here - O'Connor and Robertson were my PhD advisors so I try to promote the site when I can.)

    Sure, whatever link looks useful. If they have a Wikipedia page, also link that.

    All right, thanks. What about Isham and Butterfield, though? :-)

    Oops. Sorry about that. (Incidentally, I did fix a typo in which you spelled it "Butterfly." :-)) I had this feeling I had forgotten something...

    OK, fixed. Added Butterfield and Isham.

    Thanks.

    I did fix a typo in which you spelled it “Butterfly.” :-)

    Oh man, did I? That happens when I start editing an article on Kochen Specker in a haste while my brain is really doing something else, I suppose.

    Yep. Page through the revisions and you'll see it. But we promise not to tell anyone. :-)

    The end of the Idea paragraph is not rendering correctly for me: lots of linked pages that I see in edit mode are not there in read/show mode. Anybody else see this as well?

    Thanks for the alert. Have fixed it now. (removed a spurious square bracket)

      The new theorem […] does require any use of free will on the experimenter’s part. The theorem also strengthens the Kochen-Specker Theorem
