Owen,

The answer to your question was meant to be in the post.    I have added
some stuff to try to make it clearer.


Hempel and Oppenheim are big on the deductiive nomological account of
explanation.  
 
For example, let it be the case that I am curious why the brick fell on my
toe when I let go of it
 
If I have a theory that says that all unsupported objects fall, and the
observations that I let go of the brick and my toe was under it, then I
have an adequate explanation for my damaged toe.  Notice I didnt have to
mention gravity once

The form of the explanation is deductive syllogism:  

LAW:All sunsupported oBjects fall (This is the nomological part).  e
ANTECEDENT: This brick was  an unsupported object
ANTECEDENT:  My toe was under the brick
CONCLUSION:  Therefore, this brick fell on my toe.
