[edit] Page title
Should'nt this be named spin operator? Karol 19:40, 28 October 2005 (UTC)
[edit] Fermions
Recent edits seem to suggest that all fermions have spin of 1/2. However, I was under the impression that fermions have half-integer spin (not necessarily 1/2).--GregRM 02:51, 16 March 2006 (UTC)

- You are right. What I really meant is that all fundamental particles that are fermions have spin 1/2. Of course, composite particles can have any integer or half integer spin. I have changed the article accordingly. Thanks for the catch. Grokmoo 03:51, 16 March 2006 (UTC)
[edit] Unclear use of dash
After reading this article, some people may be confused by the expression 'spin-1/2' - in that does it mean a spin of negative half, or positive half (with a dash just for linkage)? This should probably be redfined or at least explained in the article.
[edit] Heisenberg picture
How does the spin operator look in the Heisenberg picture?
