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!).

=== 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.
