DESCRIPTION:In this talk I will discuss some basic ideas in quantum measur
 ement from the perspective of experiments that are readily available today
  in the circuit quantum electrodynamics architecture. We will focus on a r
 ecent experiment where we test an entropic uncertainty relation involving 
 weak and projective measurements. Our story spans some of the oldest ideas
  in quantum mechanics (uncertainty relations)\, involves some of the most 
 controversial (weak values)\, pulls on ideas in information theory (entrop
 ies)\, and will be presented from the humble perspective of an experimenta
 list trying to make his way through the fascinating world of quantum physi
