Task: The user wants to browse books related to chaos theory. The actual text of the goal statement submitted to CoLiDeS was "I am searching for a link for chaos theory. Chaos theory is the hottest scientific theory since relativity, a new paradigm in the realm of mathematics, mathematicians' and scientists' breakthrough discovery of order in chaos, and a mathematical formalism for describing complex, indeterminate physical systems in complicated equations. Chaos theory overturns deterministic theories of classical physics, showing that systems obeying precise laws can behave in a random fashion, and showing the emergence of order from disorder and the generation of random patterns from chaos and uncertainty."
