A central goal that modern physicists share is finding a single theory that can explain the entire universe and unite the forces of nature. The standard model, for example, leaves , , and even gravity ...

Researchers have succeeded in measuring the influence of a single electron on a vibrating carbon nanotube. This research can be important for work such as the development of ultra-small measuring ...

Usually a vibrating string produces a sound whose frequency is constant. Therefore, since frequency characterizes the pitch, the sound produced is a constant note. Vibrating strings are the basis of ...

A string is driven by a function generator that is attached to an oscillator. By adjusting the frequency of the oscillation, the string can be used to demonstrate standing waves. A strobe light is ...
