Contemporary Examples. 1  dangle mere feet from one of these behemoths to feel very small indeed. 2  And, like it or not, those are exactly the types of players at whom the Yankees like to dangle money, yearly. 3  Plenty of novels can dangle the facts well enough to merit our page-turning interest.
Bloch theorem. A theorem that specifies the form of the wave functions that characterize electron energy levels in a periodic crystal. Electrons that move in a constant potential, that is, a potential independent of the position r, have wave functions that are plane waves, having the form exp(i k Â· r).he theorem that the lowest state of a quantum-mechanical system without a magnetic field can carry no current. (solid-state physics). The theorem that, in a periodic structure, every electronic wave function can be represented by a Bloch function.
Locus Theorem 2: The locus of points at a fixed distance, d, from a line, l, is a pair of parallel lines d distance from l and on either side of l. Locus Theorem 3: The locus of points equidistant from two points, P and Q, is the perpendicular bisector of the line segment determined by the two points.
