Researchers at the University of Southampton in the UK successfully stored the entirety of the human genome sequence onto an indestructible 5D optical memory crystal no bigger than a penny. The indestructibility claims are no joke since the discs can withstand temperatures up to 1,000°C, cosmic radiation, and even direct impact forces of 10 tons per cm2.
Seems more like 5 axis than 5 dimensions.
Sounds like a slice through the crystal that can be moved up and down and rotated through 2 angles (eg roll and pitch)
5 axis and 5 dimensions are essentially the same thing, right? A 2D graph has 2 axes, a 3D one has three, 4D graph can be shown with colour representing the 4th axis, etc.
