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 ...

The hashtag makes clear that this was a reference to the show Marvel's Agents of S.H.I.E.L.D., which isn't something I watch regularly. It seems that in last week's episode, a particular magic sound ...

Parametric oscillators are a driven harmonic oscillator that based on nonlinear process in a resonant cavity, which are widely used in various areas of physics. In the past, parametric oscillators ...

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 ...

Many applications call for wide-range-tunable LC oscillators that can deliver a nearly constant-frequency, nearly harmonic-free output even when the circuit's output load changes. From a design ...

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 ...
