My mind was stretched this morning by the following passage from an article in h+ magazine:

“They were trying to establish exactly how organic photosynthesis approaches 95% efficiency, whereas the most sophisticated human solar cells operate at only half that. What they discovered is nothing short of remarkable. Using femtosecond lasers to follow the movement of light energy through a photosynthetic bacterial cell, Engel et al. observed the energy traveling along every possible direction at the same time. Instead of following a single trajectory like the electrons on a silicon chip, the energy in photosynthesis explores all of its options and collapses the quantum process only after the fact, retroactively “deciding” upon the most efficient pathway”
