John Wesley Powell worked actively for public land system
reform while a director of geographical and geological surveys in
the West from 1869 to 1894. Although this has won him acclaim as a
conservationist, the basis of Powell's linkage of reform with
scientific work is poorly understood.

A 2014 Pew Research poll revealed large gaps between public opinion and scientific opinion over environmental and biomedical issues (Funk and Rainie). Similarly, a number of recent popular books have described a growing public mistrust in scientific expertise (Mooney; Storr; Specter). Why is it, then, that so much of the...
It is desirable to be able to describe an automobile mathematically
because of the large number of variables which affect automobiles'
handling characteristics and of the high cost of building prototypes.
A mathematical analysis facilitates the construction of a
few prototypes whose configurations look most promising.
Equations of motion were...
The overall goals of this research were to identify the
major human factors problems in the mass transit driver
cockpit, to identify the operational activities, and vehicle
components that are most likely to produce accidents and
injuries and to investigate, through an in-depth study, the
most hazardous human factors problems....
The purpose of this work was to design a system for measuring
the velocity of a powder actuated fastener or drivepin during penetration.
This system would provide a tool for further investigation
into drivepin penetration characteristics. The main characteristic
of interest is the instantaneous acceleration from which the forces
on...
