New app lets you touch the fourth dimension
Posted by Xeno on July 27, 2012
The Fourth Dimension is a new app for iPad and iPhone. This app is a 30-page interactive book that explains the fourth dimension and lets you directly manipulate a 4D object called a tesseract using a unique touch-based interface.
This is the closest you will ever get to holding a chunk of the fourth dimension in your hand without using dangerous, expensive, and prohibitively theoretical lab equipment.
