Tibetan singing bowls
We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behaviour is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl’s natural vibrational modes ...
متن کاملBuilding Bowls for Miscellaneous Media
The features we present of the augmented bowl have been designed to exploit our commonsense understandings and everyday uses of container-like objects. As we’ll explain, in choosing the features, we’ve attempted to build on the ways in which physical content can be casually added to or retrieved from a bowl with little to no thought. We’ve also tried to capture the way bowls loosely contain the...
متن کاملInteraction between anions and substituted molecular bowls.
Complexes formed by anions and substituted molecular bowls were studied by means of computational methods. The bowls consisted of corannulene molecules substituted with five or ten F, Cl, or CN groups, whereas Cl(-), Br(-) and BF(4)(-) were the anions considered. Substitution with F, Cl and CN hardly affects the geometry of the bowl, but produces an inversion of the molecular electrostatic pote...
متن کاملSuper Bowls: serving bowl size and food consumption.
To the Editor: Obesity has been linked in part to the expanding portion sizes of prepackaged or preserved foods. However, adults frequently serve themselves the food they will eat for a meal or snack. We investigated how the size of serving bowls influences how much food a person decides to serve and consume in a natural environment. Methods. Graduate students were recruited to attend a Super B...
متن کاملBOWLS, f-FIBER BUNDLES, AND THE ALTERATION OF CRITICAL VALUES.
The following is a modification of the first four sections of a paper with the same title published in the Anais da Academia Brasileira de Ciencias (volume 36, 245-259 (1964)), referred to herein as M [O]. The aim is to clarify the hypotheses of the original paper. The principal results are Theorems 4.1 and 4.2. Proofs of these theorems are found in §§5-10 of M [0]. Parts II and III are in M [O...
