It is common knowledge that water runs down an incline, so do other liquids. I will begin by showing some interesting things that may happen as they flow down, followed by a discussion on the motivation for studying such flows. One of the observations on such flows is the propagation of waves, and I will briefly explain the mechanism behind their formation. The problem of flow down an incline is related to a few others, for example the flow of air past vocal cords generating speech. For the second part, I will allude to the mechanism of processes like speech generation in somewhat detail and conclude by mentioning some future work and open problems.
