‘Uncertainty’ is a complex and multifaceted property, sometimes originating in a lack of information, and at other times from quite fundamental disagreements about what is known or even knowable (Moss and Schneider, 2000). Furthermore, scientists often disagree about the best or most appropriate way to characterize these uncertainties: some can be quantified easily while others cannot. Moreover, appropriate characterization is dependent on the intended use of the information and the parti...

 Measurements Change Dramatically Depending on the Methodo...

Benoit Mandelbrot asked his famous question “How long is the coast of Britain?” long before this symposium was written, but it perfectly captures the sort of puzzle people in this crowd love. The question seems simple. Just look it up in the encyclopedia. But as Mandelbrot observed, the length of the coast of Britain depends on what you use to measure it. If you draw lines on a map to approximate the coastline, you get one length, but if you try to measure the real bumps in every inlet an...

 Replacing the Gold Standard with an Energy Standard

It has been suggested by an ingenious thinker that it is possible to use as a standard of monetary value no substance whatever, but instead, force, and that value might be measured in units of energy. An excellent development this, in theory, at any rate, of the general idea of the modern State as kinetic and not static; it throws the old idea of the social order and the new into the sharpest antithesis. The old order is presented as a system of institutions and classes ruled by men of substa...
