Scientific computing in the age of complexity
Climate modeling has come a long way since von Neumann declared it a problem too hard for pencil and paper, but tailor-made for the new digital computers. As the models and computers both evolve toward ever-greater complexity, they are changing our notions of digital simulation itself.

How much (execution) time and energy does my algorithm cost?
Do we need to design algorithms differently if our goal is to save energy, rather than time or space? This article presents a simple and speculative thought experiment that suggests when and why the answer could be "yes."
