The Exponential Function

This lecture appears in YouTube titled The Most IMPORTANT Video You'll Ever See, with this introduction:

4 million views for an old codger giving a lecture about arithmetic?? What's going on? You'll just have to watch to see what's so damn amazing about what he (Albert Bartlett) has to say.

I introduce this video to my students as "Perhaps the most boring video you'll ever see, and definitely the most important." But then again, after watching it most said that if you followed along with what the presenter (a professor emeritus of Physics at Univ of Colorado-Boulder) is saying, it's quite easy to pay attention, because it is so damn compelling.

Entire playlist for the lecture:

Albert A. Bartlett is Professor Emeritus in Nuclear Physics at University of Colorado at Boulder. He has been a member of the faculty of the University of Colorado since 1950. He was President of the American Association of Physics Teachers in 1978 and in 1981 he received theirRobert A. Millikan Award for his outstanding scholarly contributions to physics education.

Dr. Bartlett has given his celebrated lecture, Arithmetic, Population and Energy over 1,600 times. His collected writings have been published in the book, "The Essential Exponential! For the Future of Our Planet".

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

- Prof. Al Bartlett 

See Exponential Function in Wikipedia for more maths

 "Can you think of 
any problem 
in any area of human endeavor 
on any scale, 
from microscopic to global, 
whose long-term solution 
is in any demonstrable way 
aided, assisted, or advanced 
by further increases 
in population, 
locally, nationally, 
or globally?" 

 - Prof. Al Bartlett
