Quantum Chemistry and Spectroscopy - Quantum Chemistry 1.7 - Uncertainty Principle in Measurement

Short lecture on the Heisenberg uncertainty principle in measurement. The Heisenberg uncertainty principle states that during measurement of a particle's position and momentum, the product of the uncertainty in position and uncertainty in momentum must be greater than or equal to the reduced Planck constant divided by 2. The more accurately we measure the value of one, the less accurately we can measure the value of the other. This is inconsequential for large, macroscopic objects, but very important for small, microscopic objects. The Bohr model of the hydrogen atom does not obey the Heisenberg uncertainty principle, motivating the need for a more general quantum theory which will be appropriate for all quantum model systems.
