mathswithmuza on Instagram: "The Costa surface is a remarkable example of a minimal surface—a surface that locally minimizes area, meaning its mean curvature is zero everywhere. Discovered by the Brazilian mathematician Celso Costa in 1982, this surface beautifully bridges the geometry of classical minimal surfaces like the catenoid and helicoid. It has the topology of a torus with three punctures, which can be thought of as a donut shape with three holes extending to infinity. What makes it esp

These natural forces can range from small surface swirls to massive, ship-stirring maelstroms—reminding us of the ocean’s raw, untamed energy. 🌍 #NorthSea #OceanPower #NatureIsMetal #StormChasers #SeaLovers #ViralVideo #EpicNature #NorthSeaVibes #WavesOfWonder #ReelNature #OceanAddict #NatureReels #WePostSea 🌍🌊🌬️"
