ACCORDING to quantum mechanics, an oscillator possesses a definite zero-point energy of vibration, and an attempt has been made to express this result directly in terms of some general principle. It ...

When a musician strums a guitar, the vibration of the strings creates sound waves that human ears hear as music. When a guitar string is plucked, it moves a certain distance, depending on how hard the ...

Everything is blocks on springs. Pull the block, let go, and, as far as friction-agnostic physicists are concerned, it bounds back and forth forever. So will a pendulum bob---not just in a similar-ish ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Imagine plucking a guitar string. It vibrates, the sound lingers, and then fades away as the energy drains into the air. Now bring this scene down to the scale of an atom. Can an atom vibrate in the ...

A plucked guitar string can vibrate for seconds before falling silent. A playground swing, emptied of its passenger, will gradually come to rest. These are what physicists call "damped harmonic ...

Often, one needs a simple low voltage sinusoidal oscillator with good amplitude and frequency stability and low harmonic distortion; here, the Peltz oscillator becomes a viable candidate. Please see ...
