Mechanical resonance Mechanical resonance Mechanical resonance is the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system's natural frequency of vibration (its "resonance frequency" or "resonant frequency") than it does at other frequencies. It may cause violent swaying motions and even catastrophic failure in improperly constructed structures including bridges, buildings and airplanes. This is a phenomenon known as resonance disaster. Avoiding resonance disasters is a major concern in every building, tower and bridge construction project. The Taipei 101 building relies on a 660-ton pendulum—a tuned mass damper—to modify the response at resonance.
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
