The goal of this book is to show how potential flows enter into the general theory of motions of viscous and viscoelastic fluids. Traditionally, the theory of potential flows is thought to apply to idealized fluids without viscosity. Here we show how to apply this theory to real fluids that are viscous. The theory is applied to problems of the motion of bubbles; to the decay of waves on interfaces between fluids; to capillary, Rayleigh-Taylor, and Kelvin-Hemholtz instabilities; to viscous effects in acoustics; to boundary layers on solids at finite Reynolds numbers; to problems of...

The Malankara Mar Thoma Church s ecumenical outlook marked by twin facets of openness and autonomy has been the underlying ethos guiding its history, helping it to establish a unique identity. The book retells the church s ecumenical history dating back to its founding in 52 CE. This study throws ample light on the period between the significant changes of 1889 and the present times. It deals with questions such as: How did the church start practising an ecumenical outlook even before the word ecumenism was coined? Could this have resulted from the church s interaction with Indian...
