Explaining The Universe on Instagram: "A complex harmonic motion is created by adding (superposing) multiple sine waves together, each with its own amplitude, frequency, and phase. Because sine waves are the most basic form of periodic motion—pure, smooth oscillations—any more complicated vibration can be built by stacking them on top of each other. This idea is called superposition and is the foundation of Fourier analysis. • #explore #reels #explaining #viral #universe #space"

RBR.Music on Instagram: "Archaeologist demonstrates an ancient Lithophone. The lithophone is one of the earliest known musical instruments, a fascinating link between humanity and sound. Essentially, it’s a collection of stones sometimes a single rock, other times carefully arranged sets of stones crafted to produce musical tones when struck.
