"Here is a more curious case: white cats, if they have blue eyes, are almost always deaf."
Organic semiconductors span from quantum mechanics to human disease. For example, like Schroedinger's Cat, Darwin's deaf white kitty illustrates a macro quantum phenomenon. This is strong electron-phonon coupling in potent sound-absorbing organic semiconductors such as inner-ear melanin. Likewise, these materials promise exciting new technology such as light-emitting diode ( OLED ) displays, as well as literal "printed" circuits. Finally, the conducting polymer melanin figures in (e.g.) melanoma, deafness, and Parkinson's disease.
