Hi! I'm going through this post now, adding explanations of terms that are undefined, and fixing grammar and formatting:

* [Blog - quantum superposition](http://www.azimuthproject.org/azimuth/show/Blog+-+Quantum+superposition)

A question: is it really wise to use $\psi_+$ as the name for the state whose energy is $E_0 - \Delta$, and $\psi_-$ as the name for the state whose energy is $E_0 + \Delta$? I guess I know why you're doing this, but it could be a bit confusing. Maybe I'll add an explanation.

By the way, the term 'superposition' is never defined. I'll add a definition, since that's the topic of the post!
