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.

    The “5-dimensional” descriptor is only a marketing term, since the device has 3 physical dimensions and no exotic higher dimensional properties. The fractal/holographic nature of its data storage is also purely 3-dimensional. The size, orientation and three-dimensional position of the nanostructures comprise the so-called five dimensions.

      It sounds kinda like the “trick” on the internet for fitting more notes onto a note-sheet for an exam. You’re still using the same physical space to store information, but you’re introducing a new degree of freedom that allows you to increase storage density.

      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.

      It makes me think about how the 2.5d glass screen protectors with bevelled edge eventually became 3d for curved screen phones, then 5d, then 9d, and I’ve seen some silly 1000d and 9999d because clearly none of these marketing idiots remember what the d numbers even referred to in the first place. They used to explain what each d gave you and now its just a number and higher is better.
