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.

    Digitize all national history, literature, and culture. Put them on a hundred of these and distribute them all over the world. Refresh every 6 mos. Keep one on a server that all the kids can access.

    Next time there’s war or whatever intolerant culture comes into power, and loots the museums, stops culture, or blows up statues, at least you’ve kept the history alive.

    Think of it as the Library of Alexandria in horcrux form.

    P.S. Important to include a user’s guide, reference schematics for the reader, and FAQs, etched into something semi-permanent alongside all the copies.

    Only headache is assuming whoever found it could read it, and parse it.

    Requires microscopy and a compute model of the right standard, right?

    Like to actually parse the bits…

    Sure super aliens could but could post apocalyptic humans in a few centuries, who have regained enough stability to care about such things?

      Plot twist: it destroys your child. Not physically, morally.

      With these new indestructible powers, your child enslaves the entirety of mankind. Forced to adopt a bewildered child’s point of view, humans spend all day with their families and friends, get ample sleep, share food and housing, laugh, cry, and find unbeatable protection just by being near those they love.

      People love and lift each other to new heights of unshackled peace. Sciences and arts flourish and humanity enters unprecedented phases of discovery, health, and empathy.

      But because your child is the villain of this story, all the politicians and capitalists declare war on your indestructible child. They all lose and die. The villain wins. Everyone celebrates.

      The end.

        He would force everybody to be kind to animals and each other, eat raw vegetables, spend more time in the play park and participate in bushcraft activities. He would also ban chromebooks if his opinion of the school computers is anything to go by.

    The ‘5D’ in the name comes from the fact that, unlike 2D markings on a piece of paper or tape, this method uses two optical dimensions and three spatial coordinates to write throughout the material.

    Went to the article seeking answers but got only more questions.

      https://en.m.wikipedia.org/wiki/5D_optical_data_storage

      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.

      ☹️

      /edit

      Further down in the article it is a little clearer…

      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.

      The website even lists a little more…

      In order to increase the data capacity of optical storage, there is the potential of storing more than one bit in a single voxel by implementing multiplex technology. The recently developed 5D optical storage technique uses birefringence as an extra degree of freedom – the property of a medium whereby its refractive index varies depending on the polarization and direction of incident light. Birefringence generated by the orientation and size of optical nano-gratings offers two extra dimensions, providing much higher storage capacities.

      So, it’s supposedly three dimensions of position plus angle and (maybe?) polarity. So, it seems to be more than just a marketing gimmick, but I can’t find any information about the resolution of those additional two parameters, so I can’t tell if a single voxel stores two bits or two terabits.

        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.

        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.

      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.

    Nice. We need something like this. Digital archiving is still best done on magnetic tape as disk and flash drives all fail after a few decades. But even for regular users, it’d be nice to keep a digital copy of family photos that lasts forever.

    They say “billions of years” but that sounds like just the sort of thing a stray cosmic ray would ruin.

    Maybe they’re planning on using a checksum for error correction like they do with RAID.

      This isn’t a “this is your home PCs future storage” news. The read & write rates are probably abysmally slow and the intention here is for actual knowledge databases that may survive us as a species.

        And fair enough but as it stands we’re going to lose a huge amount of data if we cant get “permanent” storage solved soon.
