| 31. | Because of Noether's theorem, rotational symmetry of a physical system is equivalent to the angular momentum conservation law.
|
| 32. | The angular momentum operator plays a central role in the theory of atomic physics and other quantum problems involving rotational symmetry.
|
| 33. | The subset of Young's lattice lying below these partitions has both bilateral symmetry and 5-fold rotational symmetry.
|
| 34. | One could speak of symmetry breaking of the translation symmetry of the lattice, although rotational symmetry may be lost simultaneously.
|
| 35. | Plants often have radial or rotational symmetry, as do many flowers and some groups of animals such as sea anemones.
|
| 36. | All equations and effects of special relativity can be derived from this rotational symmetry ( the Poincar?group ) of Minkowski spacetime.
|
| 37. | Since each of its faces has point symmetry ( equivalently, 180?rotational symmetry ), the truncated icosidodecahedron is a zonohedron.
|
| 38. | However, five point groups are assigned to two lattice systems, rhombohedral and hexagonal, because both exhibit threefold rotational symmetry.
|
| 39. | The Sobel Feldman operator, while reducing artifacts associated with a pure central differences operator, does not have perfect rotational symmetry.
|
| 40. | Of these, " n " can be attributed to available translational symmetry, and the remaining to rotational symmetry.
