-L8 is new today.
+Today is [[http://www.worldmetrologyday.org/|World Metrology Day]], and we have a new kilogram standard!  Read about it at the [[https://www.nist.gov/si-redefinition|National Institute of Standards and Technology (NIST)]] site. Here is a [[https://www.vox.com/science-and-health/2019/5/17/18627757/kilogram-redefined-world-metrology-day-explained|Vox article]] that does a reasonable job of discussing it for the layperson (but note the error in the discussion of the units of Planck's constant!).
-HW2 solutions on BB (documents); HW1 grades on BB (grades).
+=== 5/20/2019 ===
+Some solid state physics in the news - ice-XVIII.
+[[https://physicstoday.scitation.org/do/10.1063/PT.6.1.20190517a/full/|https://physicstoday.scitation.org/do/10.1063/PT.6.1.20190517a/full/]]
-Wien account info on BB (grades)
+=== 5/12/2019 ===
+The first part of hwk 5 has been posted.
-Mathematica worksheets posted on Links page (2-d dispersion and 5-atom chain)
+=== 5/6/2019 ===
+The final exam will be held at the advertised time of Thursday June 13 in Weniger 304. Please bring a prepared sheet of notes, one side of one 8.5 x 11" paper.
-=== 4/16/2013 ===
+=== 5/2/2019 ===
-HW 3 is posted
+Midterm from 3-4 Friday May 3 in Weniger 304. Please bring a prepared sheet of notes, one side of one 8.5 x 11" paper.
-=== 4/15/2013 ===
+=== 4/24/2019 ===
-L7 is new at 10:23 am. L8 onwards still old
+I uploaded a new version of the density of states notes to try to make clear the distinction between D(k) and D(E).
-=== 4/7/2013 ===
+=== 4/17/2019 ===
-HW 2 is posted
+[[https://www.cambridge.org/core/journals/mrs-bulletin/news/rare-earth-topological-insulator-reveals-its-thermoelectric-properties|Here]] is some fun news about topological insulators with good thermoelectric properties.
-=== 4/6/2013 ===
+=== 4/16/2019 ===
-L4,5,6 now current.
+There is a new worksheet on the 4/15 day under "assignments" - you don't need t oturn it in, but it summarizes what we did in class and you should be able to construct it for the molecular orbitals of chain of any number of atoms.
-=== 4/5/2013 ===
+=== 4/15/2019 ===
-L3 lecture reloaded after class Friday - fixed typo on matrix slide.
+There will be a make-up class on Tuesday 4/16 at 8am for those of you who will miss Mon 4/15 for the lunch with Dr. Wineland.
-L4,5,6 are from last year - I will update them this weekend.
-=== 3/22/2013 ===
+=== 4/4/2019 ===
-The Physics department comp exam is on Friday 4/5/2013.  There WILL be class on the day (there are many students from other departments) but we will use it to review material with which PH students will be quite familiar.  A make-up class will be held MON 8 APRIL at 10am in Weniger 304.
+The [[https://physics.oregonstate.edu/dirac-electrons-one-two-and-three-dimensions|physics colloquium on Monday 4/8 at 4pm in Wngr 328]] (right after our class) is of interest.  Prof. Vikram Deshpande of University of Utah will talk about topological insulators, 2D materials and carbon nanotubes.
+=== 3/29/2019 ===
+The comprehensive exam for physics graduate students overlaps PH575 class time on Monday 4/1. In the Monday 4/1 class, there will be a review of mathematical concepts used in the class that should not be necessary for the physics grads (though I will repeat the class upon request). Others should attend. The first "official" class is on Wednesday 4/3.
+=== 2/28/2019 ===
+is the [[https://www.iypt2019.org/|International Year of the Periodic Table]], celebrating 150 years since Mendeleev discovered the period system. [[http://www.nisenet.org/events/other/IYPT2019|Explore this amazing scientific achievement]].
