An informal introduction to spin and kets

Subatomic particles have an intrinsic property that is quite strange to us. Called spin, this property has the dimensions of angular momentum. It is a rather strange name because the word spin does not imply that the particle is spinning on its own axis. All we can know is that it's a type of angular… Continue reading An informal introduction to spin and kets

Geogebra Activity: Wag the dog method for the Harmonic Oscillator

This method shows numerically, how the Schrodinger equation for a particle in a potential well V( x ) has physical solutions only for certain values of energy. The geogebra application for this activity can be found at wagthedogDownload
