 suggested that the interaction between liquid particles extends only to inaccessible distances. He studied for a clean liquid the type of surface that liquids take on drops and proved that the height of such a surface is inversely proportional to the radius of the curvature.

In 1805 Thomas Young presented to the Royal Society of London a discussion on the cohesion of liquids. Assuming the existence of a special force on the surface layer of the liquid, Young brought out the surface equilibrium, limiting heavy liquid, and found a constant the angle at which this surface meets with the walls of the tube. In addition, he examined many specific questions of this theory, and reached almost all those you conclude; to which scientists were subsequently led further research in this area. I was stopped in my research to give a detailed deveelopment of Young's by the appearance of world of Lalapce's theory of capillarity, to which I limited only some comments.

Laplace explained the capillarity phenomena by the mutaul attaction of particles and therefore created a theory that is completely consistent with the general principles of classical mechanics. But he did not find the constant angle at which the liquid surface meets the surface of the vessel. This gap was filled by Gauss, who retaining the basic assumptions of
