==== Changes to the Book as a whole ====

The later chapters for the [[toc:symmetries:|Symmetries table of contents]] do
not exist.

We should surely have a section or sections that record the formulas that are
on the inside front cover of Griffiths.  This should be nicely formatted when
printed.  Sections like [[book:math:laplacian|Laplacian]] should link to it.
\\\\
//TD: This section exists in the guide!  See [[book:guide:divgradcurl]].//

Consider whether some sections (such as the
[[book:physics:intro|introduction]]) should occur outside of
units devoted to individual courses.  Are separate introductions to the
courses and/or a separate introduction to the book needed?

Use a consistent voice: "Physicists/Scientists/Mathematicians/Professionals",
"you" (for students), "we" (for either authors alone or authors and readers).

Construct framework for homework

Construct framework for parallel Maple/Mathematica

Decide how to number figures (and equations?)

Choose format(s) for figures -- all boxed? not boxed when full line? don't use
full line figures?

==== New Sections Needed ====

Description of "chopping and adding", emphasizing the relationship between
chopping in all directions (surface and volume elements) and chopping in some
directions only due to symmetry (e.g. surfaces of revolution).

==== Symmetries ====

=== Unit 1: Point Charges ===

[[book:physics:intro|Introduction]]
  * Add a paragraph discussing our philosophy about geometric reasoning.  //~~Drafted (TD)//

[[book:physics:dimensions|Dimensions]]
  * Add easy hw
  ** consider moving the last paragraph on special functions to somewhere in the power series unit.  \\\\ (Already done in [[book:math:seriesdimension]] --- so consider removing from here.)

[[book:math:vectors]]
  * Consider switching from $\ihat$ etc to $\xhat$ etc, taking into account that this section lives in the math book.
  * Add expert remark about bases and the history of quaternions
  * <del>Change $\aa$ to $\ww$</del>.  //~~Done (TD)//

[[book:math:dot]]
  * Add expert remark on orthogonality of zero vector.  //~~Added as footnote (TD)//
  * Add expert remark on linearity.  //~~Added as footnote (TD)//
  ** <del>Fix "This" is a useful strategy;</del> add relevant hw problem?  //~~Partially done (TD)//
  * <del>Make Law of Cosines a separate section</del> (and expand proof?) //~~Partially done; good enough? (TD)//
  * Turn cube question into hw problem

[[book:physics:potentials]]
major rewrite needed (CAM)

[[book:physics:scalarfields]]
discuss so as to ensure OK for both math and physics

[[book:math:mapleintro]]
update for Mathematica!

[[book:physics:visv]]
  * <del>Needs figures: fns of 1,2 variables</del>  //Done (TD)//

[[book:physics:position]]
  * <del>Redo figure: $\rr$ points the wrong way,</del> and needs angle $\gamma$  //~~Partially done (TD)//
  * Number equations
  * Expand comment about Law of Cosines and make it an expert remark

[[book:physics:superposition]]
rewrite (CAM)

Create [[book:physics:vpoints2hint]] (and correct toc)

=== Unit 2: Power Series ===

[[book:math:powertheory]]
  * Decide which function to use

[[book:math:powerapproxhint]]
  * Figure needs to be in color (and clarify which is which in caption)
  * Consider adding a discussion of series not expanded at origin

[[book:math:powermemorize]]
  * Add expert remark about the $\Gamma$ function

[[book:math:convergence]]
  * Needs simple and expert version; current version is neither

[[book:math:seriesthms]]
  * Don't just number; use "Theorem 1", etc.

[[book:physics:vpoints]]
  * In Portfolios Wiki, ensure dipole activity split in two, as here.

=== Unit 3: Continuous Charges ===

[[book:math:intreview]]
  * Add this section to toc ( (ss)10.5? )

=== Unit 4: Potentials ===

=== Unit 5: Electric Fields ===

=== Unit 6: Electrostatic Energy ===

=== Unit 7: Review ===

==== Static Vector Fields ====

=== Unit 1: Gauss's Law ===

=== Unit 2: Current and Magnetic Fields ===

=== Unit 3: Ampere's Law ===

[[book:math:stokes|Stokes' theorem and/or Ampere's law]] (or maybe
in the physics section somewhere, or both (yeah wikis!)).  Add a regular
problem, using Stokes' theorem (i.e. Ampere's law) on a thick cylindrical
wire.  Add challenge problems, using Stokes' theorem (i.e. Ampere's law) on a
thin wire (the limit of the previous problem with delta functions), an open
cylinder, and a Moebius strip.  What do these problems tell you about the
necessary conditions for Stokes' theorem to be true?

=== Unit 4: Conductors and Boundary Conditions ===

=== Unit 5: Conservative Fields and Energy ===

(Many of these are actually from Derivatives section of Math Book.)

[[book:math:rules|Product Rules]] Add some comments about what possible things
del can do. Add a comment about how these rule might be proved.  Add a deep
link to actual proofs?

[[book:math:parts|Integration by Parts]] Expand.  Add a diagram showing a
volume and a surface.  Add words showing the geometry of the "surface" term.

[[book:physics:energy|Electrostatic Energy]] Fix wikitex, check if this
section needs expansion/clarification.

[[book:math:mmm|Murder Mystery Method]] How do we want to handle the curl
test?  Where should a discussion of this go?  How should the wiki links work
for multiple routes through the book?

[[book:physics:find|Finding Potential Functions]] Does this section have the
right physics examples?

[[book:math:second|Second Derivatives]] Add diagrams!!!!

[[book:physics:second2|Second Derivatives and Maxwell's equations]] Expand and
clarify this section

=== Unit 6: Review ===
