The thermal spring Agnikunda, in eastern India, is characterized by spontaneous emission of helium bearing natural gases. Temporal variation of the concentration of this helium has been observed for a fairly long period of time and seen to be random in nature. This irregular variation of helium...

The classic theory to derive the characteristic Rayleigh wavelength, i.e., the distance between neighbouring droplets into which an originally cylindrical liquid body disintegrates, as a consequence of Rayleigh instability, is analysed in terms of the phenomenon of self-organization due to the...
