Hartree Energy
The Hartree energy (Eh) is a unit of energy used in atomic physics, representing the total energy of an electron in a hydrogen atom in its ground state.
History/Origin
Named after the American physicist Douglas Hartree, the Hartree energy was introduced in the early 20th century as a fundamental atomic unit of energy within the system of atomic units, facilitating calculations in quantum mechanics.
Current Use
The Hartree energy is primarily used in theoretical and computational chemistry and physics to express energies at the atomic and molecular scale, especially in quantum chemistry calculations and atomic physics research.
Erg
The erg is a unit of energy in the centimeter-gram-second (CGS) system, defined as the amount of work done when a force of one dyne displaces an object by one centimeter.
History/Origin
The erg was introduced in the late 19th century as part of the CGS system of units, primarily used in physics to measure small amounts of energy before the adoption of the SI system.
Current Use
Today, the erg is largely obsolete and rarely used outside of specific scientific contexts, with the SI unit joule being the standard for energy measurement. It remains relevant in some fields like astrophysics and theoretical physics.
