The structure of invention
This paper explores the process by which radically novel technologies – ones such as radar, the turbojet, or the polymerase chain reaction – come into being. It shows that this process – “invention” – has a certain logical structure common to all cases. Invention is a process of linking some purpose or need with an effect that can be exploited to satisfy it. It may begin with a purpose or need ...
متن کاملAlpha Particle Track Detection with Celluloid Films
The solid state track detector of celluloid films (cellulose nitrate+camphor 25% an weight) using etching technique is suitable for low energy alpha particle detection . The critical rate of energy loss for track formation in celluloid films is determined as 1 .3 MeV/mg•Ecm2. Irradiated samples are etched in NaOH (6 N) solution at 46•Ž for 10 minutes . The etched tracks are observed under a vie...
