Professor's Cube the Eastsheen 5×5×5 and the V-Cube 5 are designed with different mechanisms in an attempt to remedy the fragility of the original design. There are 98 pieces on the exterior of the cube: 8 corners, 36 edges, and 54 centers (48 movable, 6 fixed). Any permutation of the corners is possible, including odd permutations, giving 8! possible arrangements. Seven of the corners can be independently rotated, and the orientation of the eighth depends on the other seven, giving 3 (or 2,187) combinations. There are 54 centers. Six of these (the center square of each face) are fixed in position. The
Lövheim cube of emotion Lövheim cube of emotion Lövheim cube of emotion is a proposed theoretical model, aiming at explaining the relationship between the monoamine neurotransmitters and the emotions. The model was proposed in a paper of 2012 by Hugo Lövheim. In the model, the three monoamine neurotransmitters serotonin, dopamine and noradrenaline form the axes of a coordinate system, and the eight basic emotions, labeled according to the affect theory of Silvan Tomkins, are placed in the eight corners. The origin corresponds to a situation where all three signal substance are low. The eight corners of the cube correspond to the eight possible combinations
