Red Sea, Knob Coral, 1997
"Illuminated by ultraviolet light, a knob coral pulsates with color as if lit from within. The coral absorbs the invisible ultraviolet light, then emits wild orange visible light. This is called fluorescence, a phenomenon of physics and biology that borders on pure magic."
—From "A New Light in the Sea," August 1997, National Geographic magazine
“一株环菊珊瑚在紫外线的照射下,随着色彩而颤动好像被从里面照亮着。这种珊瑚吸收不可见的紫外光,然后发出纷乱的橘色可见光。这叫做“荧光”——种近乎纯魔术的物理学和生物学现象。”
