  2. Hydrogen line - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_line

    An atom of neutral hydrogen consists of an electron bound to a proton.The lowest stationary energy state of the bound electron is called its ground state.Both the electron and the proton have intrinsic magnetic dipole moments ascribed to their spin, whose interaction results in a slight increase in energy when the spins are parallel, and a decrease when antiparallel.

  3. Particle in a spherically symmetric potential - Wikipedia

    en.wikipedia.org/wiki/Particle_in_a_spherically...

    Hydrogen atomic orbitals of different energy levels. The more opaque areas are where one is most likely to find an electron at any given time. In quantum mechanics, a spherically symmetric potential is a system of which the potential only depends on the radial distance from the spherical center and a location in space.

  4. Hodge theory - Wikipedia

    en.wikipedia.org/wiki/Hodge_theory

    In mathematics, Hodge theory, named after W. V. D. Hodge, is a method for studying the cohomology groups of a smooth manifold M using partial differential equations.The key observation is that, given a Riemannian metric on M, every cohomology class has a canonical representative, a differential form that vanishes under the Laplacian operator of the metric.

  5. Morse potential - Wikipedia

    en.wikipedia.org/wiki/Morse_potential

    The Morse potential, named after physicist Philip M. Morse, is a convenient interatomic interaction model for the potential energy of a diatomic molecule.It is a better approximation for the vibrational structure of the molecule than the quantum harmonic oscillator because it explicitly includes the effects of bond breaking, such as the existence of unbound states.

  6. Anharmonicity - Wikipedia

    en.wikipedia.org/wiki/Anharmonicity

    An oscillator is a physical system characterized by periodic motion, such as a pendulum, tuning fork, or vibrating diatomic molecule.Mathematically speaking, the essential feature of an oscillator is that for some coordinate x of the system, a force whose magnitude depends on x will push x away from extreme values and back toward some central value x 0, causing x to oscillate between extremes.

    en.wikipedia.org/wiki/Dream_board

    A dream board or vision board is a collage of images, pictures, and affirmations of one's dreams and desires, designed to serve as a source of inspiration and motivation. [1] The usefulness of vision boards has been endorsed by celebrities such as Oprah Winfrey , [ 2 ] [ 3 ] [ 4 ] Steve Harvey , [ 5 ] and John Pierre . [ 6 ]
