Hi:

I am working on a quantum dynamics simulator that can perhaps be used to learn quantum mechanics without resorting to the formalism. This approach may have a great potential. Here are some links to some results:

1. http://mw.concord.org/modeler1.3/mirror/quantum/coulomb.html

Fundamentally important concepts in chemistry, such as electrostatic attractions, bound state, polarization, covalent bonding, and ionization, emerge from these simulations.

2. http://mw.concord.org/modeler1.3/mirror/quantum/tunneling2d.html

Quantum tunneling effect.

3. http://mw.concord.org/modeler1.3/mirror/quantum/doubleslit.html

A simulaiton of the electron double-slit experiment.

4. http://mw.concord.org/modeler1.3/mirror/quantum/box.html
5. http://mw.concord.org/modeler1.3/mirror/quantum/circle.html
6. http://mw.concord.org/modeler1.3/mirror/quantum/ellipse.html

For fun.

Comments are welcome. Also check out my blog for progresses:

I tried to 'launch the model' in your references above, but my vista (with java) did not know a jnlp extension, so I could not run the simulations.
 
You can visit http://mw.concord.org and download the Molecular Workbench software (using the third button on that page) to your disk and double-click on the mw.jar file. It will launch the application. Then you can explore within it.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
