This lecture continues where the previous one left off in the introduction of numerical simulation of dynamical systems. We spend most of the lecture working through the bacterial growth example and adding a death process. This allows us to better highlight the ways that stocks and different flows can interact. We conclude with a challenge to simulate a toilet-tank example in a spreadsheet, which is a negative feedback loop that very different "flow" formulas but otherwise is simulated in a very similar way to the bacterial growth case.
