SUMMARY:Structure and Dynamics from Random Observations\, Physics Depa
 rtment Colloquium\, Abbas Ourmazd\, University of Wisconsin-Milwaukee
DESCRIPTION:Don’t be a control freak. 
\n
\nAt weddings\, the bridal
  photo is taken under bright lights\, with the happy couple holding st
 ill. Traditionally in science\, the “best” observations are those 
 with the largest signal from the most tightly controlled system. Like 
 bridal photos\, the results are not always exciting. In a wide range o
 f phenomena – from the dance of proteins during their function\, to 
 the breaking of molecular bonds on the femtosecond scale – tight con
 trol is neither possible\, nor desirable. Modern data-analytical techn
 iques extract far more information from random sightings than usually 
 obtained from set-piece experiments.
\n
\nI will describe on-going eff
 orts to extract structural and dynamical information from noisy\, rand
 om snapshots. Examples will include YouTube videos\, the structure and
  conformations of molecular machines such as the ribosome\, and the ul
 trafast dynamics of bond-breaking in small molecules like nitrogen.
\n
 
\nLess can be more\, but only if there is plenty of it.
