The Light on Instagram: "In mathematics, a space is not just a set of points it is a set equipped with rules that define how the elements behave, interact, or relate to each other. Change the rules and you get a different space. That’s why modern maths has many spaces. 🔸 Euclidean Space A space where you can measure distance using straight-line geometry. It’s not limited to 3D — 4D, 10D, 100D also follow the same geometric rules. 💡 Used in physics to describe real-world positions and movements
