Nature has given us tremendous inspirations since the beginning of the human civilization. Scientific progress has resulted often when new experiments have directly contradicted a well-established and verified theory. In this talk I will discuss an example of how progress was made in understanding the growth of thin films by molecular beam epitaxy when a seemingly paradoxical challenge was presented to existing theories that had been developed over a period of more than three decades. I will present an overview of the problem and how theory, simulation and experiments all played an important role in resolving this challenging problem.
