          | Description: 
             These microscope images 
            show portions of a butterfly wing. The microscope views are, clockwise 
            from top left, optical, atomic force, higher-resolution atomic force, 
            and atomic force in acoustic mode. The acoustic mode provides more 
            detail by vibrating the microscope's probe tip at its resonant frequency, 
            which makes it more sensitive. |
