mathswithmuza on Instagram: "The pseudosphere is a fascinating geometric surface that represents constant negative curvature—meaning that every point on the surface curves away from itself in all directions, similar to a saddle shape. It is generated by rotating a tractrix (a special curve where the tangent length to an asymptote is constant) around its asymptote. This process creates a surface that serves as a model for hyperbolic geometry, where the usual rules of Euclidean geometry no longer

Explaining The Universe on Instagram: "All of Earth’s water, known as the hydrosphere, covers about 71% of the planet’s surface and exists in many forms — oceans, lakes, rivers, ice, groundwater, and even water vapor in the atmosphere. About 97% of it is salt water found in the oceans, while only about 3% is fresh water. Most of that fresh water is locked in glaciers and ice caps, mainly in Antarctica and Greenland. Less than 1% of Earth’s total water is available as liquid fresh water in rivers
