In 1960, R. Byron Bird published his ground-breaking textbook entitled “Transport Phenomena”, which has then become the classical in classrooms and been translated into many different foreign languages. This book was a milestone in the classroom for generations of chemical engineers to come, bridging chemical engineering from an empirical practice into a rigorous science. I still remember how shocked I was when I first deep dived into this book: I considered this book as the “Mathematical Principles of Natural Philosophy” in chemical engineering. For the first time, I clearly saw how those complicated phenomena in chemical engineering could be explained mathematically based on a few elegant fundamental equations. We all know that if we have a model complex enough to capture the essentials of the system that we are interested in, and a computer powerful enough to produce a result within an acceptable time frame, we could essentially run our experiments in our virtual laboratory: the computer. In the 1960s, what a computer could achieve seems to be trivial by the standard of modern computers. However, scientists and engineers clearly saw that this was the future: tomorrow most of our experiments conducted in the laboratory would happen in the virtual world of a computer.
