New Tech Item of the fucking Decade (or more!)
See here (simpler), here (more complete) Edit: Even better link
The really short version: Back in the 70s, a really smart guy theorized that there were four basic electronic components: resistors, capacitors, inductors, and another thingy called a memristor, a device that stores the previous value put into it. The math proved that this gadget should exist, but nobody knew how to make one.
Until the early 90s, when some other really smart dudes at HP figured it out.
Today their article was published in the latest issue of Nature, describing the memristors they were able to construct. They’re made of titanium oxide, and they’re 15 nanometers wide. (Hint: That’s really small.)
The simplest of all possibilities for these things is that they could make a solid-state, long term storage device that stores data when it’s powered down (like a hard drive) but has very fast access (like RAM.) Think about that for a second. Try and visualize the concepts behind creating a program with one single data store. No limitations on what you can store in memory. No worrying about updating what’s being written to disk. No memory requirement printed on the side of the box.
This is very likely the revolution of our time. No joke. If they can make these things work in mass production it will cause a dramatic change in the way operating systems work. Computing will never be the same ever again. It could be sanely argued that it will be the most fundamental change to computing since the invention of the transistor.
If any of the two or three or so of you who actually read this have access to a college library, see if you can get the article in question from Nature. I would really, really love to read it. The name of the article is “Electronics: The fourth element,” by James M. Tour & Tao He, Nature, vol. 453, num. 7191.
