The Statistical Paleontology of Charles Lyell and the Coupon Problem

Lyell, a founder of the science of geology, used statistical models to describe the changes that had occurred in the earth and its environment. From this model he attempted to establish a time frame for each epoch. This article shows that Lyell's model is equivalent to the classic coupon problem included in many probability texts. Furthermore, it is shown that the time frame deduced by Lyell is inconsistent with the model he was using. The proper time frame consistent with the model is provided. A second model that was considered by Lyell is also investigated.

Communicating the risks arising from geohazards

Summary. Construction on, or in, the ground is affected by uncertainty. This includes the inherent variability of the ground itself, the effect of natural and human processes on the ground and the difficulties that are associated with the management and implementation of any construction works. The risk is considered to be in two parts: the probability of occurrence of a geohazard and the effect that this will have on the outcome of the project. Geohazards are determined as part of the ground investigation process, the principles of which are well established. Nevertheless uncertainty remains and communication between the professions and with the public is not always effective. Barriers are created by unfamiliar terminology and a lack of a forum for education and exchange of views. It is argued that the public must be continually involved—not only as recipients, but also as contributors.
