Dr. Albert Bartlett is emeritus Professor of Physics at the University of Colorado at Boulder, USA. He has given this lecture on “Arithmetic, Population, and Energy” over 1,500 times.

“The greatest shortcoming of the human race is our inability to understand the exponential function.”

A challenging statement. Having seen the lecture now I can understand why it has been so popular, and is so important. I came across it recently and felt it was worth sharing.

You can watch it on YouTube here as a series of bite-size 9 minute clips.

(After that you might like this unrelated take on applying risk management.)
