Arithmetic, Population and Energy - a talk by Al Bartlett (university of Colorado)

 (At your risk).

Euroelectron note: One day, more than 10 years ago a book dropped from the library and sat on the floor with the appendix open. This appendix was a summary of this lecture. The book is Conceptual Physics by Hewitt (a student of Richard Feynman). These concepts obviously had their influence too on designing low power consumption, battery powered  electron tube or transistor amplifiers, usually referred to a Pleiades amplifiers on euroelectron blogger. On this lecture you may find all you need to understand or predict what is happening around you.
