It’s a way to encode a block of text that can be read with today’s mobile devices, but the underlying binary nature of a QR code should be understood by any sufficiently advanced society in a post-human future. You’ve probably seen them on product packaging and in advertisements. The optical disk developed by the researchers employs an increasingly common type of 2D matrix barcode called a QR code. This inert solid is durable and is transparent to light, which allows the tungsten pattern to be visualized. Tungsten is somewhat malleable, though, so the researchers encapsulated the metal in silicon nitride. Basically, if you build something out of tungsten, it will remain mostly unchanged over time. The DISH WHEEL DISC and the SHAPING DISC.The team settled on elemental tungsten because it has a very high melting point of 3,422 degrees Celsius and low thermal expansion.
