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.

    So, as I understand it, and I don’t, 5D is just fancy marketing due to the really weird properties of the crystals used to store the data in. They are just calling properties of the crystal, dimensions.

    I found the wiki page on it https://en.wikipedia.org/wiki/5D_optical_data_storage

    According to the University of Southampton:

    The 5-dimensional discs [have] tiny patterns printed on 3 layers within the discs. Depending on the angle they are viewed from, these patterns can look completely different. This may sound like science fiction, but it’s basically a really fancy optical illusion. In this case, the 5 dimensions inside of the discs are the size and orientation in relation to the 3-dimensional position of the nanostructures. The concept of being 5-dimensional means that one disc has several different images depending on the angle that one views it from, and the magnification of the microscope used to view it. Basically, each disc has multiple layers of micro and macro level images.[16]

      It’s actually cromulent technical terminology to call those extra degrees of freedom “dimensions”, it’s only in common parlance that “dimension” is restricted specifically to spatial dimension. Having hundreds or even thousands of dimensions is not unknown in data science.
