Cartesian Coordinates

The video explores the concept of four-dimensional space, which is challenging to visualize. It explains that the fourth dimension involves moving at right angles to three-dimensional space. Modern technology and computer simulations aid in visualizing 4D space. The video describes how dimensions are defined by the number of coordinates needed to specify a point, with 4D space requiring four coordinates: w, x, y, and z. It introduces the tesseract, a 4D hypercube with 16 vertices, 24 faces, and 32 edges, and discusses its geometric properties. The video also highlights architectural attempts to incorporate 4D concepts, such as the design of La Grande Arch in Paris, which resembles a tesseract.
