This series of mind maps contain knowledge of physical quantities and measurement techniques, wave,current electricity, deformation and nucleus physics, while it excludes the units of kinematics, as we have already known it well in mechanics. Despite some brief information of key definitions (in my point of view), diagrams are drawn to help both remembering and understanding. Some of the necessary information is listed, for instance, the wavelengths, frequencies, uses and hazards of the 7electromagnetic waves are required to be learnt. Also, the method of connecting the knowledge by mind maps is beneficial for reviewing.
