A hallmark of complex systems are the presence of order and randomness. The interplay between them allows for robust function. A mathematical framework for uncovering structure and randomness is found in information theory. As one example I will illustrate how information measures help uncover the mechanism of glass formation. I will also discuss protein dynamics and other examples from biochemistry. No background in information theory required to attend.
