Resonator Resonator A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones. Another example is quartz crystals used in electronic devices such as radio transmitters and quartz watches to produce oscillations of very precise frequency. A cavity
The Trouble with Physics formulation; and that it has not been mathematically proved finite. Some experts in the theoretical physics community disagree with these statements. Smolin states that to propose a string theory landscape having up to 10 string vacuum solutions is tantamount to abandoning accepted science: The scenario of many unobserved universes plays the same logical role as the scenario of an intelligent designer. Each provides an untestable hypothesis that, if true, makes something improbable seem quite probable. The book generated much controversy and debate about the merits of string theory, and was criticised by some prominent physicists including Sean Carroll and string
