quantum biology

Monday, February 4th, 2013

Anyone feel daring enough to make a fool of himself, to venture a guess that anything we recognize as psychic phenomenon (by that, I mean the things which aren’t total bullshit to begin with) and the soul might come out of the research in quantum biology? The New Age quacks will be all over this, building elaborate systems out of these fragments of information that will rival any role playing game. However, simple universal mechanism isn’t going to work for explaining every biological system much longer.

And honestly, I look forward to the weird mess that results.

The Hadron Collider

Friday, February 12th, 2010

The Large Hadron Collider (LHC) is the world’s largest and highest-energy particle accelerator complex, intended to collide opposing beams of protons charged with approximately 7 TeV of energy. Its main purpose is to explore the validity and limitations of the Standard Model, the current theoretical picture for particle physics. It is theorized that the collider will produce the Higgs boson, the observation of which could confirm the predictions and missing links in the Standard Model, and could explain how other elementary particles acquire properties such as mass. The LHC was built by the European Organization for Nuclear Research (CERN), and lies underneath the Franco-Swiss border near Geneva, Switzerland. It is funded by and built in collaboration with over eight thousand physicists from over eighty-five countries as well as hundreds of universities and laboratories. The LHC is already operational and is presently in the process of being prepared for collisions. The first beams were circulated through the collider on 10 September 2008, and the first high-energy collisions are planned to take place after the LHC is officially unveiled on 21 October 2008. Although a few individuals have questioned the safety of the planned experiments in the media and through the courts, the consensus in the scientific community is that there is no conceivable threat from the LHC particle collisions. Concerns have been raised in the media and through the courts about the safety of the particle physics experiments planned to take place at the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator to date, built by the European Organization for Nuclear Research (CERN) near Geneva, in Switzerland. The claimed dangers of the LHC particle collisions, which are scheduled to begin on 21 October 2008, include doomsday scenarios involving the production of stable micro black holes or the creation of hypothetical particles called strangelets. The potential risks of these unprecedented experiments were reviewed in 2003 by the LHC Safety Study Group, a group of independent scientists, who concluded that, like current particle experiments such as the Relativistic Heavy Ion Collider (RHIC), the LHC particle collisions pose no conceivable threat.A second review of the evidence commissioned by CERN in 2008 reaffirmed the safety of the LHC collisions in light of further research conducted since the 2003 assessment. The 2008 report was reviewed and endorsed by CERN’s governing body and by the Division of Particles & Fields of the American Physical Society and was published in the Journal of Physics G. It concludes that any doomsday scenarios at the LHC are ruled out because the physical conditions and events that will be created in the LHC experiments occur naturally in the universe without hazardous consequences.

26 Things That Don’t Make Sense

Wednesday, September 9th, 2009

(via mefi.)

13 Here13 There.

They range from pretty neat to WTF, viz.:

The GEO600 gravitational wave detector in Hanover, Germany, has not yet detected any gravitational waves. As a consolation prize, it may instead have uncovered the ultimate nature of reality.

In 2008, physicist Craig Hogan at the Fermi National Accelerator Laboratory in Batavia, Illinois, was trying to work out how we might test the idea that everything we see as physical reality is the result of a kind of projection from the boundary of the universe. This is known as the holographic principle.

The information held at the boundary is not smooth, but composed of “bits”, each one occupying an area that corresponds to the most fundamental quanta of distance in the universe. This is the Planck length, around 10-35 metres – far too small for us to see the individual bits. When this information is projected into the volume of the universe, however, each bit gets magnified. That means we might just be able to see pixellation in space-time.

The kinds of scales involved still mean it would only be detectable in the most sensitive instruments we have – such as the gravitational wave detectors looking for the ripples in space-time caused by violent cosmological events such as the collision of two black holes. Hogan worked out how the pixellation might manifest itself for GEO600 and sent his result to the researchers there.

By strange coincidence, the GEO600 team had been having problems with “noise” in their detectors. But here’s the kicker: the noise had uncannily similar characteristics as Hogan’s anticipated signal. Is it indeed the result of information that resides at the edge of the universe? “The issue is still unresolved,” says Karsten Danzmann, principal investigator for GEO600. “The noise is still there and we have no explanation.”

The answer may only come after the instrument is upgraded to make it even more sensitive, a step that is due to be completed this time next year.


Let me keep my tachyons!

Wednesday, March 18th, 2009

The math would be completely over my head, and some of the thought models that are thrown out in the article are a little tricky. (Light cones? Easy to picture, but… ) However, tachyons are absolutely necessary to keep us sane. Why? Without tachyons, the universe is deterministic. Time is an illusion. Free will does not exist.

Someone needs to refute Wheeler and Spencer’s paper just for my peace of mind.

barrier of speed of light broken?

Thursday, August 16th, 2007

Some physics were investigating a phenomenon called “quantum tunnelling,” and believe that they have found a way to break the barrier of the speed of light. They are having microwaves photos travel “instantaneously” between prisms as much as three feet apart.

I don’t know. This all sounds very familiar. There have been a bunch of stories about teleportation in recent years, and this seem to be a similiar principle. My science is very rusty though. It just sounds like old news. Information seeming to travel faster than light via quantum entanglement that is…

levitation now feasible as well

Tuesday, August 7th, 2007

Casimir force is not something that i’m overly familiar with, but apparently scientists at the University of St. Andrews in Scotland have managed to find a way to get it to repel instead of attract. Apparently they can use this to levitate small objects to an extent.

Yeah. Levitation.

More please. The article points out that these are the same researchers who show that invisibility cloaks are possible.
