Why HN links it

HN readers link Al Bartlett's lecture "Arithmetic, Population and Energy" and related writing on exponential growth, using it to explain why doubling growth is hard to grasp and unsustainable with finite resources.

Summarised by Claude from a sample of 17 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

Professor Emeritus Al Bartlett - Physics at University of Colorado at Boulder - articles on exponential growth, peak oil and population growth, sustainability, renewable resources and the environment

  1. “The greatest shortcoming of the human race is our inability to understand the exponential function” https://www.albartlett.org/presentations/arithmetic_populati... “Growth” as the politicians and the lobbyists push it is simply not sustainable. But both “the left” and “the right” have their agendas not to let you discuss or act on that. "Bacteria grow by doubling. One bacterium divides to become two, the two divide…

  3. I'd like to quote Al Bartlett: His thesis: " The greatest shortcoming of the human race is our inability to understand the exponential function " An example from the rest of the talk: "Bacteria grow by doubling. One bacterium divides to become two, the two divide to become 4, the 4 become 8, 16 and so on. Suppose we had bacteria that doubled in number this way every minute. Suppose we put one of these bacteria into…

  5. Specifically: "In 2016, a report published by the UK All-Party Parliamentary Group on Limits to Growth concluded that "there is unsettling evidence that society is still following the 'standard run' of the original study – in which overshoot leads to an eventual collapse of production and living standards".[45] The report also points out that some issues not fully addressed in the original 1972 report, such as clima…

"It's a great pleasure to be here, and to have a chance just to share with you some very simple ideas about the problems we're facing.

  10. But this is the problem of exponential growth - you can sustain it without even noticing the detrimental effects, until suddenly you can't. The resource usage of all the doubling time periods until the last one would have used up only 50% of the resources available(this could be millions of years, depending on the exponent), and then suddenly the last one would use up all the resources left. This is repeatedly exemp…

  11. One of the biggest problems with the way the news is presented is the idea of framing ( http://en.wikipedia.org/wiki/Framing_(social_sciences) ) -- stories are presented in a narrowly-framed viewpoint so most public debate only occurs inside the framed perimeters. Our perspective is constrained so we see things through a "reality tunnel" ( http://en.wikipedia.org/wiki/Reality_tunnel ). We never see the whole picture…

  13. "One bacterium is put in a bottle at 11:00 a.m. and it is observed that the bottle is full of bacteria at 12:00 noon. Here is a simple example of exponential growth in a finite environment. This is mathematically identical to the case of the exponentially growing consumption of our finite resources of fossil fuels. 11:58 a.m. -> Bottle is one quarter full. 11:59 a.m. -> Bottle half-full ! 12:00 noon -> Bottle is ful…

  14. Do you imagine we will box up our terrestrial waste heat and launch it into the sun? The portion people who leave the Earth do not matter, the fate of the portion who remain remains the same.

  16. Overpopulation is the elephant in the room that no one talks about, and I believe that most of the issues today have it at its core. Much of propaganda is designed to dance around the issue of population control -- "the primary responsibility of government is to project the minority of the opulent from the majority" (listen this Harvard talk on "Propaganda and Control of The Public Mind" http://www.youtube.com/watch…

    Thanks for mentioning Al Bartlett here. This video is very relevant to this post and worth watching. Al Bartlett is a brilliant man and does a wonderful job explaining the profound implications of misunderstanding exponential growth.

  21. The earth will run out of space before that happens. "If the current [population growth rate] of 1.3% per year could continue, the world population would grow to a density of one person per square meter on the dry land surface of the earth in just 780 years, and the mass of people would equal the mass of the earth in just 2400 years" ( http://www.albartlett.org/presentations/arithmetic_populatio... , http://www.yout…
