For three days Jeopardy contestants on the TV show took a beating at the hands (or voice) of IBM’s new supercomputer Watson. “Watson, come here I need you!” was not the call the contestants were making. Rather, it was more like, “Not again. Go away.”

Yes, Watson (not to be confused with Hal) time and again kicked the snot out of the other contestants by answering the questions correctly in his quirky voice. If you happened to have caught the Conan O’Brien spoof of Watson it was pretty entertaining and Watson sucked up to Conan and got personal with his sidekick Andy Richter.

Watson told a few “Yo Mama” jokes followed by a few “I did your wife” jokes after which Richter dismembered Watson with a baseball bat.

Even though Watson showed the superior intellect on Jeopardy, the higher-than-thou voice needs to be retooled. I guess you can’t expect a great amount of social skills from a computer especially one programmed by a bunch of geeks who probably don’t themselves have an overabundance of social skills.

Perhaps giving Watson the voice of comedian Bobcat Goldthwait would have enlisted a bit more empathy towards the supercomputer with a chip on its shoulder (as well as many inside the box). The outside the box thinking by the IBM programmers has to be admired though. In addition, the willingness to put their money where their mouths are in such a public forum was an act of bravery.

But, I have to end this blog quickly now, as my laptop has just started talking back to me and I can’t let this go on too long. Heaven only knows what could happen next. I’m grabbing my baseball bat just in case.

Nanolasers on Silicon Chips Pave Pathway to Supercomputers

Quantum computing isn’t here yet as computers based upon silicon chips are still today’s standard. Bridging the pathway however may be nanolasers on silicon chips developed by researchers at UC Berkeley in Northern California.

The engineers at the university are using III-V materials to create LED’s and lasers. The process they are using is also scalable for mass production since similar technology is already being used to produce thin film solar cells and LED’s.

With the use of nanotechnology the scientists are creating nanopillars upon the silicon chips to help quickly distribute the near infrared light. According to UC Berkeley, “Once the nanopillar was made, the researchers showed that it could generate near infrared laser light – a wavelength of about 950 nanometers – at room temperature. The hexagonal geometry dictated by the crystal structure of the nanopillars creates a new, efficient, light-trapping optical cavity. Light circulates up and down the structure in a helical fashion and amplifies via this optical feedback mechanism.

“The unique approach of growing nanolasers directly onto silicon could lead to highly efficient silicon photonics, the researchers said. They noted that the miniscule dimensions of the nanopillars – smaller than one wavelength on each side, in some cases – make it possible to pack them into small spaces with the added benefit of consuming very little energy.”

This breakthrough could create an optoelectronics revolution within the industry leading to disruptive technology not only in supercomputer and super-networking and super-telecommunications as well.
