Indeed, researchers have previously observed them in four dimensions, but they did so by mapping a 4D system to a 2D one. The latest work instead involves the direct creation of a 4D topological ...

Leader and Physics Contemplating the mysteries of the fourth dimension is time well spent. From what it is and why it only goes one way to how we perceive its passage and whether we could live ...
