Study Notes
Measurement of Amount of Substance
- The mole (mol) is the unit of measurement for the amount of substance.
- One mole contains exactly 6.02214076 × 10^23 elementary entities.
Avogadro Constant
- The Avogadro number is the number of particles in one mole.
- The numerical equivalence of the Avogadro constant is approximately 6.02214076 × 10^23.
de Broglie-Bohm Theory
- The de Broglie-Bohm theory is an interpretation of quantum mechanics that postulates the existence of an actual configuration of particles even when unobserved.
- The theory is named after Louis de Broglie and David Bohm.
- The guiding equation, which governs the evolution of the wave function over time, is a fundamental aspect of the de Broglie-Bohm theory.
- The de Broglie-Bohm theory is deterministic and non-local, meaning that the position of particles is determined and can be instantaneously affected by events at a distance.
- The de Broglie-Bohm theory attempts to resolve the measurement problem in quantum mechanics by providing a clear and causal explanation of the collapse of the wave function.
