-===== Articles =====
-  * Roald Hoffmann, How chemistry and physics meet in the solid state, Angew. Chem. Int. Ed. Engl. 26 (1987) 846-878 [[http://onlinelibrary.wiley.com.proxy.library.oregonstate.edu/doi/10.1002/anie.198708461/abstract|Link via OSU Library]]
-(a comprehensive look at the first part of this course from a chemist's perspective)

-(beyond the scope of this course, but a nice extension of the above to surfaces)
-===== Journals =====
+===== Journals =====
+Some links are through the OSU Library Proxy Server; others are direct.  Try linking through the OSU Library if you can't read or download journal content.
   * [[http://arjournals.annualreviews.org/loi/conmatphys|Annual Review of Condensed Matter Physics]] is a new addition to the "Annual Review" Series of journals (also Mat. Sci , Chemistry etc).  A good place to find summaries of quickly-developing fields by very respected authors.

   * [[http://pubs.acs.org.proxy.library.oregonstate.edu/journal/nalefd|Nanoletters]] is a monthly journal specifically addressing physics and chemistry, of nanomaterials and nanodevices.
-  * [[http://prola.aps.org.proxy.library.oregonstate.edu/|Physical Review Online]] (through OSU Library). Phys. Rev. Lett. usually features articles on hot, new materials, but materials is by no means its focus.  Phys. Rev. B is devoted to solid state.

+===== Mathematica =====
+Mathematica (by Wolfram) is one of several extremely useful software programs that is useful for simple visualization of functions, computer-aided algebra, and is also a vehicle for very sophisticated programming.  I highly recommend you use it for classwork, for research and for fun.  As long as you are an OSU student, you are permitted a free copy for use on your own computer.  [[http://www.physics.oregonstate.edu/~tate/COURSES/ph424/Mathematica_info.html|Here]] is a link to a page I wrote for my PH424 physics class describing how to get access, how to use Wolfram's fantastic documentation and tutorials, and I added a few simple templates.
+Here are some Mathematica notebooks that I wrote that are relevant to PH575.
+  * {{:ylm_visualization.nb|visualization of spherical harmonics}}
+  * {{:ylm_sp_linear_combinations.nb|visualization of s and p orbitals}} - real combinations of spherical harmonics
+  * {{:lcaoapproximationtobondingmolecularorbitalinhydrogen-mod4.nb|molecular orbitals}} - MOs of 5 atoms in a line.  Use s or p, and pick mode.
+  *{{:2d_dispersion_squarelattice.nb|2D square lattice dispersion}}
+===== OSU seminars =====
+Not part of the course, but watch these for relevant topics ...
+    * The physics [[http://www.physics.oregonstate.edu/events-SSO|Solid State and Optics Seminar]]  meets W 4:00 - 5:00 pm in WGR 304.
+    * The [[http://matsci.oregonstate.edu/seminars.php|Materials Science Seminar]] meets Th 3:00 - 4:00 pm in Covell 117.
