Last week, NPR and I shared a little paean to photosynthesis, which I defined as "the molecular scale shenanigans plants use create food from sunlight."
The piece was short, coming in at under three minutes. That doesn't leave a lot of time to talk details. So, in the interest of scientific completeness, we present the above video which goes into lovely details, including the baroque Calvin Cycle.
