Abstract
The values of alpha(s) determined from low and high energy measurement s are in irreconcilable contradiction with each other. The current sta tus of the problem is critically reviewed. Consequences of the alpha(s ) contradiction, in conjunction with other anomalies detected at the Z peak, are discussed. This article has been updated in accordance with experimental numbers reported at summer conferences.
