Kessler highest levels of government it is often proclaimed that our problems will be solved by research even when the speakers have little knowledge of either science or its natural Much legislation provided by the political system in the United States is an exchange for financial contributions to campaigns.

As noted in a short article Kessler 1991 the political establishment is pleased to provide the wherewithal in part because the hope for favorable outcomes is a basis for postponement of actions that are politically difficult to implement even though they could be immediately effective. And of course research must be encouraged a plethora of research outcomes in every field of study are the principal basis for our industrial and postindustrial worlds and further highly favorable results seem inevitable. For example a recent helpful outcome in Japan has produced light emitting diodes LEDs that are about 50 efficient in their production of light from electrical energy and the cost of LED production is being reduced rapidly. LEDs may be on track to replace both incandescent lights with efficiency about 5
