The Large Hadron Collider and Single Points of Failure

Sunday, February 22nd, 2009

ColliderWhen I was in the military working with critical systems, we put a lot of emphasis on single points of failure. We dealt with satellites, and it wasn’t unusual for a new spacecraft to have multiple failures caused by the stresses of being launched. Nearly every piece of hardware was redundant, however, so we would just route processing around the failed components.

Apparently the folks at CERN have not learned this lesson. The Large Hadron Collider, a $5.4 billion atom-smasher is expected to be out of commission for a year due to a single, badly soldered electrical connection along its 17-mile length. Repairs will cost about $20 million. Now that is an example of error-intolerant design.

Gecko-Inspired Tape

Friday, November 7th, 2008

GeckoIt wasn’t that long ago that scientists discovered how a Gecko is able to climb sheer walls. The neat thing about gecko adhesion is that it has a strong grip in one direction but can easily be peeled off. Several variations of gecko-inspired tape have already been created, and researchers have now duplicated the effect with sheets holding carbon nanotubes—resulting in a stronger bond than other materials. I think we may see it as a consumer product in the not-too-distant future.

CNN’s Holograms Were Not

Thursday, November 6th, 2008

HologramCNN’s election-night coverage had a new special effect that it called “holograms.” I had my doubts about this, and the linked article sets the record straight. The 3D “hologram” images were special effects added to the video feed and were not visible to the newscasters in the studio (even though they appeared to be).

A Commercial Quantum Computer

Saturday, August 9th, 2008

ScienceA company named D-Wave Systems has produced a working 28-qubit quantum computer and plans to sell time on it. This is a big deal. Quantum computers can solve problems that are too complex or time-consuming for conventional computers, and they have the potential to change the world.

Say Goodbye to LCD Televisions

Wednesday, August 6th, 2008

HDTVThinking about purchasing one of those monster-sized LCD/plasma TVs for thousands of dollars? Well you may want to hold off for a couple years and get an OLED TV instead.

Textron Systems BLU-108 Submunition

Wednesday, June 11th, 2008

BoomThis weapon is capable of identifying and destroying multiple ground targets. The first link is a video explaining how the weapon works, including real film footage. The second link has an embedded video showing a reconstruction of an Iraq war event where the BLU-108 played a major part. It’s just amazing how far weapons technology has come.

Building a Supercomputer with Graphics Cards

Monday, June 2nd, 2008

ScientistBack in November, Chad’s News discussed the possibility of using GPUs to perform computations. Well, now it’s been done officially. According to the linked article, a PC with four graphics cards (8 GPUs total) has the computational power of 300 dual-core CPUs. This comes with a caveat, of course, as GPUs only excel at certain types of problems. But still, I think it’s a pretty impressive accomplishment.

Wall-climbing Robot

Wednesday, May 21st, 2008

RobotResearchers from SRI International have created a robot that can climb walls made of common building materials. From the article: “The as-yet-unnamed robot uses electro-adhesion to cling to the wall, generating electrostatic charges between the wall substrate and itself to keep from falling.” The linked article has a video of the robot in action.

…and the World is Consumed By Self-replicating Machines

Thursday, April 10th, 2008

PrinterChad’s News has previously discussed 3D “printers,” but a team of engineers is designing one that will be inexpensive, open-source, and capable of replicating itself. This makes me wonder how long it will be until we have functioning Von Neumann machines

Self-contained Micro Nuclear Reactors

Thursday, December 20th, 2007

EnvironmentToshiba is creating micro nuclear reactors that are capable of powering a single building (or a city block). They’re self-contained and totally automatic, and last for about 40 years.
