The cool quirks of trying to visualize four dimensions in three. After all, we are so used to visualizing three dimensions in two dimensions, but…four into three is quite a bit more difficult.
A couple of weeks ago, I watched a YouTube video from Albert Hwang that talked about visualizing four dimensions by analogy with how we visualize three dimensions in two dimensions (e.g., a drawing of a three-dimensional object). Thirteen-minute video, includes closed captions. Enjoy!
