All four fundamental forces (ie strong, weak, gravitational and electrostatic) are considered. "Mindocular' is a fictional character who has a 'minds eye' with excellent magnification and resolution and can 'see' individual particles in matter, and determine their behaviour. He looks at metallic, ionic and covalent solids.
