The idea of a fourth dimension, a concept essential to complicated physics topics such as special relativity, is extraordinarily difficult to comprehend in our three-dimensional world. This complex topic gets broken down in a beautiful and easy-to-follow way in The Fourth Dimension app. The app is set up like an interactive booklet, where users flip through a guided explanation of dimensional space with short activities at each step along the way. Users can rotate and manipulate a representation of a four-dimensional cube, called a tesseract, and read about how this shape changes in each dimension below it. The app is beautifully designed and easy to use and provides a fun and interesting way to conceptualize this inherently difficult topic.
