How Everything Is Made on Instagram: "In the 1930s, a few pioneering builders experimented with houses constructed by machines that poured concrete in continuous, layered forms — functioning almost like an early precursor to modern 3D printing. Instead of stacking bricks or erecting wooden frames, these systems used slip-form or contour-crafting–style rigs that traveled along rails, shaping walls directly on-site as they deposited wet concrete. This technique made it possible to create flowing c

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"
