I had been impressed by the fact that biological systems were based on molecular machines and that we were learning to design and build these sorts of things. K. Eric Drexler
As the number of unexplained, irreducibly complex biological systems increases, our confidence that Darwin's criterion of failure has been met skyrockets toward the maximum that science allows. Michael Behe
Coherent behavior is the characteristic feature of biological systems. Ilya Prigogine
Few scientists acquainted with the chemistry of biological systems at the molecular level can avoid being inspired. Donald Cram
Biological engineering is not necessarily understanding systems but rather, I want to be able to design and build biological systems to perform particular applications. Drew Endy
Biological systems are dynamical, not easily predicted, and are creative in many ways... In the old equilibrium worldview, ideas about change were dominated by the action-reaction formula. It was a clockwork world, ultimately predictable in boring ways. Chris Langton
