Kochen-Specker theorem revisited
Abstract
The Kochen-Specker theorem is a basic and fundamental 50 year old non-existence result affecting the foundations of quantum mechanix, strongly implying the lack of any meaningful notion of "quantum realism", and typically leading to discussions of "contextuality" in quantum physics. Original proofs of the Kochen-Specker theorem proceeded via brute force counter-examples; often quite complicated and subtle (albeit mathematically "elementary") counter-examples. Only more recently have somewhat more "geometrical" proofs been developed. We present herein yet another simplified geometrical proof of the Kochen-Specker theorem, one that is valid for any number of dimensions, that minimizes the technical machinery involved, and makes the seriousness of the issues raised manifest.

V1:12 pages. V2: Now 17 pages, 8 figures. Massive revision of the technical heart of the article. We now use a simplified two-step descent argument; the measure-theoretic arguments used in V1 were deeply flawed and have been replaced. Physics conclusions are of course unaltered
