Large Hadron Collider Update

Thursday, August 20th, 2009

Atom SmasherCERN’s super-expensive Large Hadron Collider (LHC) was shut down last September due to one badly-soldered electrical connection, with the expectation that it would be up and running this September. This will not be the case. After inspecting the entire system, technicians found 5,000 faulty electrical connections, apparently due to poor workmanship. In an effort to get something in the way of results, CERN will run the collider at half-power starting this November. Then in late 2010 it will shut down the system to make the repairs necessary for full-power usage. So it may be years before we see the ground-breaking results that were originally expected.

Gyroscopes in Zero-G

Tuesday, May 26th, 2009

ScientistThe video in the linked article is from the International Space Station, and shows the stabilizing effect of gyroscopes. The demonstration is done in zero-gravity, and the “gyroscopes” are portable CD players.

Thinking Outside the Universe

Tuesday, April 7th, 2009

SpaceThis article is one of the more readable explanations that I’ve seen of how universes are created. It’s short and concise, yet manages to cover topics from quantum multiverses to what may exist outside of our universe.

DNA Encryption

Monday, March 23rd, 2009

CryptoDNA can be used to make a one-way process suitable for encryption. I don’t completely understand the details, but the concept is interesting. I’m also thinking that DNA cryptography might be easier to implement than quantum cryptography.

Insurance Based on Genetics

DNA HelixIs Gattaca the future? It will be if insurance companies have their way. I’ve read about pending legislation making it illegal to discriminate based on genetic predispositions. I’m not sure, however, if anything’s been made into law yet.

Is the Universe a Giant Hologram?

Tuesday, February 10th, 2009

PixellationThis theory contends that the interior of the universe is simply a replication of the information on its outer surface. And since the 3-D (okay, 4-D but let’s keep this simple) interior can hold much more data than the 2-D surface, the internal information has a granularity, sort of like what happens when you expand a bitmap image. It sounds pretty bizarre, but there are mathematical and experimental results that may back it up. The “blurring” threshold is believed to be about 10-16 meters, which is measurable by existing equipment.

Do You Feel Lucky Punk?

Monday, January 19th, 2009

ScientistProfessor Richard Wiseman decided to research luck. He found that “lucky” people have attitudes/habits that actually create their luck, without their realizing it. He also determined it’s possible to increase a person’s luck by having him/her perform exercises to strengthen those attitudes and habits. I was astounded by the fake newspaper advertisement that went unnoticed by the “unlucky” group.

Scientists Prove That Mass Comes From Nothing

Saturday, December 13th, 2008

ScientistAt the level of quantum vacuum (or quantum foam), elementary particles just pop into and out of existence from nothing. But it turns out that these “virtual” particles comprise the majority of what we know as matter. Note also that some theorists believe the Big Bang, and the existence of space and time, came from a similar sort of quantum fluctuation.

Large Hadron Collider

Saturday, September 13th, 2008

ScientistThe new Large Hadron Collider (LHC) has been making the news over concerns it will spawn a black hole and destroy the world. Some enterprising individuals have even created websites to let us know whether or not Earth has been destroyed. But this is all tangential stuff. For those interested, the linked video contains a concise and clear explanation of how the LHC works.
