Diabolical cube Diabolical cube The diabolical cube is a three-dimensional dissection puzzle consisting of six polycubes (shapes formed by gluing cubes together face to face) that can be assembled together to form a single 3 × 3 × 3 cube. The six pieces are: one dicube, one tricube, one tetracube, one pentacube, one hexacube and one heptacube, that is, polycubes of 2, 3, 4, 5, 6 and 7 cubes. There are many similar variations of this type of puzzle, including the Soma cube and the Slothouber–Graatsma puzzle, two other dissections of a 3 × 3 × 3 cube into polycubes which use
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
