A liquid droplet hovering on a hot surface is commonly referred to as a Leidenfrost droplet. In this study, we discover that a Leidenfrost droplet involuntarily performs a series of distinct oscillations as it shrinks during the span of its life. The oscillation first starts out erratically, followed by a stage with stable frequencies, and finally turns into periodic bouncing with signatures of a parametric oscillation and occasional resonances. The last bouncing stage exhibits nearly perfect…

Parametric Random Vibration

This monograph is a state of the art presentation of parametric random vibration, based on an enormous number of published papers and reports, and provides the necessary tools for deriving response statistical functions and techniques for examining stochastic parameter stability, as required in later chapters.

Theoretical Physics

It is an almost impossible task for the teacher to guide the studies of his pupils so wisely that nothing of importance for exhibiting the unity of physical theory shall be omitted and, at the same time, sufficient time shall be allowed for proper assimilation of principle and application even on the part of the brightest honours man.
