Focuses on some of the properties of the regular tetrahedron and the cube. Number of edges of the tetrahedron as compared to the number of the cube's faces; Assertion that any two face diagonals issuing from the same vertex of a cube form a 60-degree angle; Assertion that the altitudes ...

摘要: We give rigorous, computer assisted proofs of a number of statements about the effect on the volume of lengthening various edges of a tetrahedron. Our results give new and sharp polynomial inequalities concerning the Cayley–Menger determinant and its partial derivatives....
In fact, 5 is the minimum number of tetrahedra required to compose a cube. Inscribing tetrahedra inside the regular compound of five cubes gives two more regular compounds, containing five and ten tetrahedra. Regular tetrahedra cannot tessellate space by themselves, although it seems likely enough ...
of various D-branes and open strings attached to them can be naturally associated with the vertices, edges and faces of a tetrahedron, we will call these instantons thetetrahedron instantons. We carefully work out the moduli space of tetrahedron instantons, which can be viewed as an interpolation...
The basic structural unit of physical Universe quantation, tetrahedron has the fundamental prime number oneness.” Buckminster Fuller “Within it (tetrahedron) lies the energy that holds all life together. The bonds that hold atoms, particles and molecules together, all the way down to nanoparticles...
For a tetrahedron with four spin (1/2) particles, I know there are three separate energy levels at $$l=2,l=1,and l=0$$. My question is how I would go about finding the degeneracy of each level. I know that the number of states must be $$2^4$$. Any clues on where to start...
Consider the same 3D solid structure as Figure 9.1, whose domain is divided in a proper manner into a number of tetrahedron elements with four nodes and four surfaces, as shown in Figure 9.2. A tetrahedron element has four nodes and each node has three DOFs (u, v, and w), which makes...
