Part 2/10:
This article serves as an introduction to a comprehensive series focused on learning how to think in four dimensions. We will explore how our perception of three dimensions can be extended to visualize and understand 4D shapes, delving into the geometry involved and employing lower-dimensional analogies for better comprehension. The journey will take us through various concepts such as hypercubes, hyperspheres, and the intricacies of curved space, leading to discussions on more advanced mathematical ideas such as quaternion and complex functions.
