</span>You adopt the position that theory is only justified if it is in<br>
agreement with an experiment. There are many people adopting that point<br>
of view, but it is *not* the only one. An excellent article can examine<br>
deeply which are the factors that control the property you are interested<br>
in, for instance. Or explaining why those factors are important. A<br>
tinkertoy model can be the main contribution to an extraordinary Physical<br>
Review Letters.<br>
<br>
Remember that theory contributes to knowledge, and only when theory is<br>
so well polished that it can compete in agreement and precision with<br>
experimental measurements it can contribute to databases of properties.<br>
<br>
Being realistic, a careful examination of the articles published<br>
lately (a few years) in the journal you want to send your research is<br>
the best step in determining the orientation of your contribution.<br>
Many contributions tend to use "results pending confirmation" and the<br>
referee answer may be 'let us wait to the experiments' ... ;-)<br>
<br>
