PH 575 Introduction to Solid State Physics, 3 credits, Spring 2019



Today is World Metrology Day, and we have a new kilogram standard! Read about it at the National Institute of Standards and Technology (NIST) site. Here is a 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!).


Some solid state physics in the news - ice-XVIII.


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.
