Abstract:
:The physics of bubbles and of their oscillations is extremely complex and attempts at its mathematical description are generally inaccessible. Yet some idea, in broad descriptive terms at least, is very helpful in understanding bubble phenomena of clinical interest. A brief attempt to provide such a description is given in this article.
