-Let's quickly pause to give a classification of the types of responses that might be expected from
-materials.
-\subsubsection*{Permanent polarization:}  here, \({\bf P} \neq 0\) even if \({\bf E} = 0\).
-These are the {\bf electrets}.
+For labelling sections and equations, I've preferred to use a semantic
+format instead of traditional numbers.
 </p>
 
 <p>
-\subsubsection*{Nonlinear dielectrics:}
-\[
-P_i = \sum_j \alpha_{ij} E_j + \sum_{jk} \beta_{ijkl} E_j E_k E_l + ...
-\]
-(even-order terms usually absent, but could be there in principle).
-\subsubsection*{Linear dielectrics:}  only linear term is there.  Most general:
-\[
-P_i = \varepsilon_0 \chi_{ij} E_j
-\label{Gr(4.38)}
-\]
-where \({\bf \chi}\) is the {\bf electric susceptibility tensor} (it's a tensor of rank 2),
-which cannot depend on \({\bf E}\) (otherwise we go back to the nonlinear case).
-Common in crystals, leading to for example double refraction.
-\subsubsection*{Linear isotropic dielectrics:}  at a given point, the electrical properties of
-the dielectric are independent of the direction of \({\bf E}\) (isotropy).  Liquids fall into
-this category.  We here have

+This has a number of advantages: the labelling is
 </p>
 
+<ul class="org-ul">
+<li>easier to remember in the long run</li>
+<li>stable under tree structure modifications</li>
+</ul>
+
+
+<p>
+but also come with some things which need getting used to:
+</p>
+
+<ul class="org-ul">
+<li>the loss of clear notion of ordering</li>
+<li>abbreviations being as short as possible, thus needing learning</li>
+</ul>

+<p>
+<b>Section labelling</b>: floated right next to the title of any section, you will see the
+label together with a permalink (pointing to the main site's version
+of that particular section). Under a section's headline, you will also
+sometimes see references (in small gray letters) to corresponding sections
+in complemetary <a href="./a_l.html#a_l">literature</a>.
+</p>
+
+<p>
+<b>Equation labelling</b>: similarly to sections, some (but not all)
+equations also carry a semantic label, given in parentheses to the right
+of the equation. As per sections, a permalink is also given, together
+with corresponding equation numbers in complementary literature.
