Parity-odd asymmetries in the electromagnetic decays of compound nuclei can sometimes be amplified above values expected from simple dimensional estimates by the complexity of compound nuclear states. Using a statistical approach, we estimate the root-mean-square of the distribution of expected parity-odd correlations (s) over right arrow (n)center dot(k) over right arrow (gamma), where (s) over right arrow (n) is the neutron spin and (k) over right arrow (gamma) is the momentum of the gamma, in the integrated gamma spectrum from the capture of cold polarized neutrons on Al, Cu, and In. We present measurements of the asymmetries in these and …
Notions Of Progress, C. Waite
Notions Of Progress, C. Waite
Articles
The question of progress and a concern with relatedness are elements of the same puzzle. The very idea of progress, or lack of it, indicates something about the role machines can play in one’s life. Notions about how technology can be used – to improve, subvert, destroy, extend, or interrogate – reveal the interplay of human and machine. What notion of progress might adequately capture the complex interdependence of human and machine in a way that illuminates our current predicament? To ask whether specific events make things better or worse does not reveal what guides our notion of better and …
