This article reviews recent developments in tests of fundamental physics using atoms and molecules, including the subjects of parity violation, searches for permanent electric dipole moments, tests of the C P T theorem and Lorentz symmetry, searches for spatiotemporal variation of fundamental constants, tests of quantum electrodynamics, tests of general relativity and the equivalence principle, searches for dark matter, dark energy, and extra forces, and tests of the spin-statistics theorem.

An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid , liquid , gas , and plasma is composed of neutral or ionized atoms. They are so small that accurately predicting their behavior using classical physics —as if they were tennis balls, for example—is not possible due to quantum effects. Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons. Only the most common variety of hydrogen has no neutrons.

Atom , smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry. Most of the atom is empty space. The rest consists of a positively charged nucleus of protons and neutrons surrounded by a cloud of negatively charged electrons.

The rest consists of a positively charged nucleus of protons and neutrons surrounded by a cloud of negatively charged electrons. The nucleus is small and dense compared with the electrons, which are the lightest charged particles in nature.

Atoms and Molecules describes the basic properties of atoms and molecules in terms of group theoretical methods in atomic and molecular physics. The book reviews mathematical concepts related to angular momentum properties, finite and continuous rotation groups, tensor operators, the Wigner-Eckart theorem, vector fields, and vector spherical harmonics. The text also explains quantum mechanics, including symmetry considerations, second quantization, density matrices, time-dependent, and time-independent approximation methods. The book explains atomic structure, particularly the Dirac equation in which its nonrelativistic approximation provides the basis for the derivation of the Hamiltonians for all important interactions, such as spin-orbit, external fields, hyperfine. Along with multielectron atoms, the text discusses multiplet theory, the Hartree-Fock formulation, as well as the electromagnetic radiation fields, their interactions with atoms in first and higher orders. The book explores molecules and complexes, including the Born-Oppenheimer approximation, molecular orbitals, the self-consistent field method, electronic states, vibrational and rotational states, molecular spectra, and the ligand field theory. The book can prove useful for graduate or advanced students and academicians in the field of general and applied physics.

На ВР последняя стена стала уже тоньше яичной скорлупы. Джабба поднял брови. - Хорошо, это ничего не дает. Начнем вычитание. Я беру на себя верхнюю четверть пунктов, вы, Сьюзан, среднюю.

Но одно не давало Фонтейну покоя - то, что Стратмор решил прибегнуть к услугам Халохота.

И повернулся к офицеру. - Вы уверены, что в коробке все его вещи. - Да, конечно, - подтвердил лейтенант.

Он поднял глаза на видеомониторы, и у него закружилась голова. Одна и та же картинка смотрела на него со всех двенадцати мониторов наподобие какого-то извращенного балета. Вцепившись руками в спинку стула, Бринкерхофф в ужасе смотрел на экраны.

 Все произойдет, как булавочный укол, - заверила его Сьюзан.  - В тот момент, когда обнаружится его счет, маяк самоуничтожится.
