Equation \ref{simple} says that the Hamiltonian operator operates on the wavefunction to produce the energy, which is a scalar (i.e., a number, a quantity and observable) times the wavefunction. Such an equation, where the operator, operating on a function, produces a constant times the function, is called an eigenvalue equation .
10 wrz 2020 · What happens if we mix two substances? If we blast a molecule with a laser, what will it do? If we introduce a biomimetic into a living organism, how will it respond? Experiments produce data that relate to each individual observation.
4 gru 2019 · Coulomb's law is a physical law stating the force between two charges is proportional to the amount of charge on both charges and inversely proportional to the square of the distance between them. The law is also known as Coulomb's inverse square law.
14 paź 2024 · scalar, a physical quantity that is completely described by its magnitude. Examples of scalars are volume, density, speed, energy, mass, and time. Other quantities, such as force and velocity, have both magnitude and direction and are called vectors.
Professor Cathy Drennan introduces this series of lectures about basic chemical principles. She describes her path to becoming a chemist and reveals her first impression of the discipline of chemistry.
This course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis.
