    Abstract

    It is known now, beyond any doubt, that a moving fluid in contact with a solid body13; will not have any velocity relative to the body at the contact point. This condition of not13; slipping over a solid surface has to be satisfied by a moving fluid. This is known as the noslip13; condition and is stated routinely in the text books of Fluid Mechanics. But it remained a13; difficult problem for a long time. We will first give in this article some basic ideas connected13; to this problem so that the historical notes added 13; afterwards will be appreciated better. Some recent experimental data of interest, the phenomenon at the molecular level and the case of turbulent flows will be discussed briefly. We will see that this simple looking13; phenomenon was so difficult to comprehend and even the giants had to struggle. The students today are taught it in one stroke. It is not surprising that some of them get13; bothered about it. If one did not, we will see why one should be.
