Arithmetic, Population and Energy (Lecture)
Professor Bartlett has given his celebrated onehour lecture, Arithmetic, Population and Energy: Sustainability 101 over 1,600 times to audiences with an average attendance of 80 in the United States and worldwide. His audiences have ranged from junior high school and college students to corporate executives and scientists, and to congressional staffs.
He first gave the talk in September, 1969, and subsequently has presented it an average of once every 8.5 days for 36 years. His talk is based on his paper, Forgotten Fundamentals of the Energy Crisis, originally published in the American Journal of Physics, and revised in the Journal of Geological Education.
Professor Al Bartlett begins his onehour talk with the statement, The greatest shortcoming of the human race is our inability to understand the exponential function.
He then gives a basic introduction to the arithmetic of steady growth, including an explanation of the concept of doubling time. He explains the impact of unending steady growth on the population of Boulder, of Colorado, and of the world.
He then examines the consequences steady growth in a finite environment and observes this growth as applied to fossil fuel consumption, the lifetimes of which are much shorter than the optimistic figures most often quoted.
He proceeds to examine oddly reassuring statements from experts, the media and political leaders  statements that are dramatically inconsistent with the facts. He discusses the widespread worship of economic growth and population growth in western society.
