s, for example, the lack of proof for the convergence of the series used in the context of problems which are not self adjoint, nor even linear. The results thus obtained must consequently be submit ted to an exacting confrontation with experimental observations. - Even though, the ‘1 imited information obta978-3-642-82097-7978-3-642-82095-3

Flow Stability of Non-Newtonian Fluidslar weight polyethylene oxide (PEO) in water, … The addition of such small quantities of polymer causes only little perceptible change in the viscosity or to other measurable rheological properties, relative to that of the pure solvent. Thus it is rather astonishing that the addition of minute quant

Solar Models and Helioseismologyn an experiment the initial conditions cannot be reproduced with infinite accuracy and these infinitesimal differences produce finite effects after some time. Therefore, turbulent flows are very difficult to study and the physics involved in the transition from laminar to turbulent flows remains an

An Introduction to Helioseismologynvestigation of the circumstances which determine whether the motion of water shall be direct or sinuous”. One would say today that the laminar flow cannot be observed if some dimensionless group of parameters (the Reynolds number) exceeds a critical value, close to 2200. One has thus to search for
