Into the Unknown
Quantum MechanicsUniversity of Colorado Boulder If you’re with mechanical or aerospace engineering backgrounds and looking for a course that presents an introduction to quantum mechanics, this course is right for you. The course covers the most fundamental concepts and plenty of stuff. I have to say the pace of this course is fast, you need…
Unfortunately, real atoms (including hydrogen atoms) are not very well described by the simple theory. There are more things contribute to the actual atomic structure: Higher order effects Spin-orbit coupling Relativistic Nuclear spin Zeman Identity particles, that leads to the Pauli exclusion principle. Multiple electrons, the electromagnetic fields associated with the electrons can interact. Spin-Orbit…
External Motion Particle in a box is the simplest problem in quantum mechanics. A particle is just translating back and forth between the walls of the box. If there is no external field acting on the particle, i.e. no force acting on the particle except at the walls, then you can decompose the problem into…
Quantum mechanics is the mathematics of atomic and molecular structure. We seek to determine allowed quantum states and their energies. A Short History A definite understanding that atoms are composed of separate particles (nuclei and electrons) did not really occur till toward the end of the 19th century. The development of quantum mechanics is strongly…
