Memory Storage in a Sphere

How does one selectively read or write to these nanoparticles, particularly to the nanoparticles not visibly at the surface of the sphere? My concern is in selecting these nanometer-scale particles.

There are videos out now that show electrical circuits that, while still wired up, are actually energized by the field that is created, and that information tends to flow through that field, not through the wires. Therefore I think that the short answer is Field Modulation. Provided that the sphere is contained within a field, then the signal can get through. It is not necessarily about contact or conduction. just for fun, try this one, or others like it. https://www.youtube.com/watch?v=oI_X2cMHNe0

Something along this line of thinking is being utilized today. See the Wiki sub article Holographic Data Storage/Two Color Recording.

As with everything, there appear to be advantages and disadvantages to the scheme.

That has been around and evolving for a while. Back in the late 80’s early 90’s. It was been looked at using biologically that was sensitive to light that where the color did that color change red/green (1 & 0) by the speed of light?…

It would be binary type of storage/communications.. as far as intensity of color, that would be interesting, kinda like ‘fuzzy logic’ catchphrase from back in the 90’s

as far as using it as a memory storage, the obvious issues is retrieval… what alternative is there to a FAT

Nothing about sphere or nanpartical. but there appears to be working on it which I’m sure you already know.

I’m sure DARPA is on it…
