Image of the Week: Chemical Flowers This photomicrograph reveals a floral-like pattern formed by absorption around a central nucleation point in a crystallizing chemical film. The observed colors arise from variations in the orientation and thickness of the crystal grains as viewed through crossed-polarizers and a wave plate. The intricate structure results from molecular charges. —Karl Gaff, Art of Science Photography, Dublin, Ireland *Link in Bio #Chemical #Flowers #photomicrograph #film #colors #crystal
