By holding back water, dams create reservoirs that can be used for drinking water, irrigation, hydroelectric power generation, flood control, and recreation. There are several types—such as gravity dams (which rely on their weight to resist water pressure), arch dams (curved, transferring force into the val

vt.physics on Instagram: "Why Flour Sticks but Rice Falls Straight Through - The Science of Sifting When particulate materials such as rice or whole grains are passed through a sieve, their relatively large mass and smooth surface texture enable gravitational forces to dominate over any weak adhesive interactions with the mesh. In contrast, flour consists of fine particles with a low mass-to-surface-area ratio. The resulting high specific surface area increases the relative significance of surfa

Explaining a Movie on Instagram: "@explainingamovie teaches you something new about movies everyday! Flow (2024), directed by Gints Zilbalodis, is a dialogue-free animated feature created almost entirely with the open-source software Blender. The story follows a cat navigating a world submerged by floods, forced to join other animals on a raft in a journey of survival and reluctant cooperation.
