This invention describes a 4-dimensional periodic table of elements (4D PT) based on the 4 known quantum numbers of the atom, namely, n (principal), l (azimuthal), m (magnetic) and s (spin), which determine the 4D Cartesian co-ordinates (n,l,m,s) of a 4-dimensional cubic lattice. Since the four quantum number combinations of each element are unique by Pauli's exclusion principle, each chemical element occupies a different vertex of this lattice and has a unique location in 4D space. The 4 quantum numbers are used as independent vectors of a 4-dimensional vector space so that quantum numbers can be added in the same manner as vectors are added. The 4D PT displays complementarity and the principle of zero cyclic sum in numbers associated with elements. The 4D PT of elements and their coordinates extend to chemical molecules and compounds by adding coordinates of individual elements into composite coordinates of molecules and compounds in a larger expansive PT. The higher-dimensional table of elements and compounds can be represented in any digital media where they can be manipulated graphically and interactively by various input devices including virtual reality. The 4D PT can be displayed in print media as 2D charts, or 2D cards that can be combined in various ways. It can be physically built in different materials as 3D model kits for teaching, learning, research and practice of chemistry in academia and industry. The 3D model kits can be like space frames comprising nodes and connecting struts or 3D blocks or connected 2D panels.

Disclosed are mortise and tenon joint structures for Chinese characters formed by building members having the same or different configurations, and a method for inputting Chinese characters by using the building members. The Chinese characters are de-structured such that each Chinese character consists one or more radicals which are formed by the mortise and tenon joint structures or variants thereof. The variants of the mortise and tenon joint structures are formed by shift, rotation or combination of shift and rotation of the building members of the mortise and tenon joint structures. This establishes an inputting method between the Latin letters and Chinese characters.

A system and method for teaching children in the field of music, and more particularly to teach children to play the piano and read musical notes using physical objects with images of characters assigned to fingers and animals assigned to musical notes, with assigned colors and shapes, and all incorporated within themed environments presented in continuing stories.

Training labs for training linemen and other power or utility technicians are disclosed. The training labs can be configured to provide equipotential zone (EPZ) grounding training in overhead and/or underground power scenarios. In some instances, the training labs can be mobile. For example, a mobile training lab can comprise an overhead training side that comprises one more deployable overhead power poles and/or an underground side comprising one or more component cabinets.

Disclosed are a Chinese character structuring member, a system of mortise and tenon joint structures of Chinese characters formed by the Chinese character structuring member and a method for inputting Chinese characters. An entity component of Chinese characters includes the following three structures: an entity component provided with a connecting mechanism at a middle and/or one end or both ends of the entity component configured to join with other entity components of the Chinese characters; an entity component provided with a connecting mechanism entity component extending from one end of the entity component to the other end of the entity component without exceeding the entity component of the Chinese characters; and an entity component provided with at least one connecting mechanism on the entity component that includes a plurality of sub entity components connected end to end and rotatable at the joint.
