Nanotech

“Declaring that “nanotechnology has the potential for unintended consequences, which is precisely why we can’t allow the societal implications to be an afterthought,” National Science Foundation Director Rita Colewell announced two new grants have been awarded that are worth more than one million each”2. These grants are for studies on the impact on society. The grant recipients will be studying things like impacts of manufactured material on our health and the environment.

On the medical side, nanotechnology will be able to “monitor, repair, construct and control the human biological system at the molecular level” 3. This won’t be possible, however, until the machines and robots are developed. This is being actively pursued by a number of different companies. One is the Institute for Molecular manufacturing. They are a nonprofit foundation that rese

Holographic data storage has evolved from other optical media like the CD and DVD. However, “it allows on million bits of data to be stored in a single flash of light”11. Light from a laser is split into two beams. One beam carries data and the other is a reference. These two beams will intersect on the recording medium and the hologram is formed. The major challenge lies in the development of suitable storage medium. InPhase Technologies is taking a storage medium to market. It says the medium has a 50-year archival life and can store from 2 gigabyte, on the size of a postage stamp, to 100 gigabyte on a disk12.

The optical computer uses photons that travel on optical fibers to perform the same functions as today’s silicon-based processors. It is supposed to be able to solve a problem in 1 hour that would take 11 years for a computer today to solve. Optics use light to carry the information. Several pieces of data can be sent down the same fiber using different colors of light as opposed to sequentially9. The result is parallel processing.

Quantum computers differ from what we use today. Today’s computers rely on the laws of physics while qu
