* Illumination: Clearing toxic imprints from the luminous energy
If 3C 273 B always had the same brightness, the total luminous energy
it would have radiated over that time would be more than that radiated from 100 million supernovae!
Photosynthesis has been attracting much attention for many years due to its superior ability of transforming luminous energy
to the chemical energy of plants, algae and cyanobacteria, and many researches have been performed on the crystal structure of photosystem II, the mechanisms of energy and electron transfer, and relevant artificial simulation (Nield et al., 2000; Kamiya & Shen, 2003; Ferreira et al., 2004; Biesiadka et al., 2004; Nelson & Ben-shem, 2004; Standfuss et al., 2005).
On a solid--usually dark--background, they meet and separate, open and close, overlap, and move away from each other, or crash together with a sudden impact that produces its own movement and luminous energy
. The lines might grow in volume or acquire more curves, but they still glide over the solid background, cross each other, and weave together, carrying a dynamic all their own.
