HIDDEN-VARIABLES AND THE 2 THEOREMS OF BELL,JOHN

Although skeptical of the prohibitive power of no-hidden-variables the orems, John Bell was himself responsible for the two most important on es. I describe some recent versions of the lesser known of the two (fa miliar to experts as the ''Kochen-Specker theorem'') which have transp arently simple proofs. One of the new versions can be converted withou t additional analysis into a powerful form of the very much better kno wn ''Bell's Theorem,'' thereby clarifying the conceptual link between these two results of Bell.
