I wish I could play the game. I have the same java applet problem. Hopefully I'll be able to play later. A few words on quantum mechanics - it is very tricky.

I wish I could play the game. I have the same java applet problem. Hopefully I'll be able to play later. A few words on quantum mechanics - it is very tricky. Someone doesn't understand quantum mechanics by taking a class in it or in getting an undergraduate physics degree. I am sure even many (or all) physics professors have limitations in their knowledge. It's not that the rules are complicated, it is the implications when it is applied in the real world. You do seem to have gained a good level of understanding though. I have a comment on the nature of a wave function, as described in the section "It's wavelike, but not watery". It states that wavefuntions can act like particles. This may be wording that I just do not understand, but I would want to clarify it. Take the wave function for an electron - this is not a wave of "electon". It is a wave of probability (sort of) for an electron. The electron itself is always a particle. The motion of the electron is described by the wave. In this way the electron has wave properties. To take an example, let's shoot an electron gun at a target. Suppose the resulting wavefunction of the electron has a uniform amplitude over the target when it "hits". What is the damage to the plate? Is it uniform damage? No. The damage is always at a single point of impact. We see the result of the electron hitting the target, not the wave function hitting the target. Now, if we shoot lots of electrons, the damage will be pretty uniform, since they will be distributed all over the plate. But it will still consist of a bunch of point impacts. I just wanted to be clear about differentiating the wave function from the object whose state (position, momentum, whatever) is described by the wave function.
