Bartosz Ciechanowski's Interactive Guide to Sound: From Air Molecules to Pressure Waves

In this interactive article, Bartosz Ciechanowski explains what sound is and how it travels. Starting with air molecules, he shows how collisions create pressure, then demonstrates how a moving plate generates pressure waves that we perceive as sound. You can play with simulations and a mini keyboard to hear how frequency affects pitch.

When those pressure waves reach our ears we perceive them as sound.

    So we have Turing test. We now need Bartosz test for AI for general intelligence. give it concept, get it explained like this :)

    The progression here is what impressed me most... You start with individual air molecules bouncing around and somehow end up understanding harmonics, interference and etc. Love this kind of articles!

    I've seen a lot more of these types of visualizations pop up in blogs recently but they don't feel as high quality as the ones on this site.

More from this day
