The Physics of Limits

Abstract

Physics offers a solid foundation upon which to build simple yet powerful perspectives on challenges we face inhabiting a finite planet. This work offers suggestions for framing the human endeavor in the contexts of space, time, energy, and ecology, as well as hinting at productive order-of-magnitude calculations that students can use to gain powerful insights into constraints within which we must operate. Tools from the physical sciences can be employed to clarify demands associated with expansion of modernity within a finite resource environment. Our complex world can appear to be primarily governed by human constructs in political, legal, ethical
