The following branches have especially felt his influence: - chemical physics, capillarity and viscosity, theory of gases, flow of liquids, photography, optics, colour vision, wave theory, electric and magnetic problems, electrical measurements, elasticity, sound and hydrodynamics.
Capillarity and Surface Tension.-Reference should be made to the article Capillary Action for the general discussion of this phenomenon of liquids.
Not only does water move upwards, but it is transferred by capillarity in all directions through the soil.
It tends to improve the tilth and the capillarity of the soil by binding sands together somewhat and by opening up clays.
If a number of small enough holes be drilled through a solid substance which is not wetted by the liquid, our knowledge of the phenomena of capillarity shows us that it needs pressure to force the liquid into the holes.
Gay-Lussac's earlier researches were mostly physical in character and referred mainly to the properties of gases, vapourtensions, hygrometry, capillarity, &c. In his first memoir (Ann.
The dependency of capillarity upon abruptness of transition.

In its full extension the subject of capillarity is very wide.
