An identification carrier for a toy for replaying music or a spoken story, includes a standing surface, a magnet and an identification, wherein the identification changes a property of an external magnetic field when it enters the magnetic field, and the magnet is arranged closer than the identification to the standing surface and/or at least one surface normal to the standing surface passes only through the magnet or only through the identification.

A stress reduction and/or pain reduction method and system, includes measuring an initial level of user stress, which level is unacceptable, having the user hold a card having multiple single digit math problems therein, the problems being in multiple series of four problems, the math problems comprising at least one of addition, subtraction, and multiplication problems, displaying to and instructing the user to complete a first series of four and only four problems correctly, displaying to and instructing the user to complete a second series of four and only four problems incorrectly, again measuring the user's stress level and repeating the steps of displaying and instructing, and measuring, until the output from the device is acceptable. The same process may be followed using a camera or video camera and analyzing the image(s) for a Duchenne smile, in place of or in addition to measuring the indicator of stress.

This invention describes a 4-dimensional periodic table of elements (4D PT) based on the 4 known quantum numbers of the atomn (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 and hence in the periodic table. The 4D PT of elements extends 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 or print media as 2D charts or cards. The 4D PT #can be physically built as 3D model kits comprising nodes and connecting struts or 3D blocks or connected 2D panels.

An audio demonstration kit encourages understanding of audio concepts by enabling children to construct and study speaker performance. In a particular embodiment, the audio demonstration kit includes a paper speaker and instructions. The paper speaker includes a backplate, a suspension, and a diaphragm cut from a single sheet of paper. The demonstration kit may feature an amplifier that is configurable to accommodate various hardware additions as a child is ready for more progressively challenging construction. For example, the amplifier of an embodiment allows single and dual mode operation, as well as drives a rotary motor and is coordinated with a strobe light. The amplifier of an embodiment is synchronized with the strobe light and a moveable platform to create the impression of that jiggling figures attached to the table are dancing. Interfaces with smart phone, recording, and other technologies further enhances and encourages the learning experience.
