A Test for String Theory After All? Or Just PR? | Wired Science from Wired.com
At last? String Theory has been around for a while. However, most authorities considered it as only an interesting speculation as there was thought to be no way to test the theory, therefore taking it out of the realm of science.
See the Wikepedia entry below:
Problems and controversy
Although historically string theory is an outgrowth of physics, some contend that string theory should (strictly speaking) be classified as something other than science. For a scientific theory to be valid it must be verified empirically, i.e. through experiment or observation. Few avenues for such contact with experiment have been claimed.[20] With the construction of the Large Hadron Collider in CERN some scientists hope to produce relevant data, though it is widely believed that any theory of quantum gravity would require much higher energies to probe directly. Moreover, string theory as it is currently understood has a huge number of equally possible solutions.[21] Thus it has been claimed by some scientists that string theory may not be falsifiable and may have no predictive power.[22][23][24][25]"

There is one question that persistently circles the community of Unidentified Flying Object (UFO) true-believers: If the government has nothing to hide, UFO fans often ask, then why is it keeping so many UFO records under lock and key?"
Yes, UFO's are probably just goofy, but there is just enough out their to tease our minds.

Origins: CERN: Ideas: The Higgs Boson
The Search for the Higgs Boson. What is it? See below. Also, see CERN
There, you will learn about the Swiss-French particle accelerator that will open in April to find both the Higgs Boson and perhaps create a very small black hole!
Origins: CERN: Ideas: The Higgs Boson: "An oft-cited analogy describes it well: Imagine you're at a Hollywood party. The crowd is rather thick, and evenly distributed around the room, chatting. When the big star arrives, the people nearest the door gather around her. As she moves through the party, she attracts the people closest to her, and those she moves away from return to their other conversations. By gathering a fawning cluster of people around her, she's gained momentum, an indication of mass. She's harder to slow down than she would be without the crowd. Once she's stopped, it's harder to get her going again.
This clustering effect is the Higgs mechanism, postulated by British physicist Peter Higgs in the 1960s. The theory hypothesizes that a sort of lattice, referred to as the Higgs field, fills the universe."

Windbelt - Third World Power - Wind Generator - Video - Breakthrough Awards - Popular Mechanics
"Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don't scale down well—there's too much friction in the gearbox and other components. "With rotary power, there's nothing out there that generates under 50 watts," Frayne says. So he took a new tack, studying the way vibrations caused by the wind led to the collapse in 1940 of Washington's Tacoma Narrows Bridge (aka Galloping Gertie)."
The new alternative energy sources keep coming on line. Any of you from the Seattle Tacoma area will be very familiar with Gertie.

Big Radio From the Stars -- Berardelli 2007 (927): 1 -- ScienceNOW
Blast from the Past!
Big Radio From the Stars -- Berardelli 2007 (927): 1 -- ScienceNOW
"By Phil Berardelli
ScienceNOW Daily News
27 September 2007
Astronomers have a new mystery on their hands. A team studying data from a recent sky survey has spotted a huge burst of radio waves that came and went in the blink of an eye and has not returned since. Figuring out what caused the cosmic broadcast could provide new insights into the dynamics of neutron stars and black holes and perhaps give astronomers another tool to figure distances to the farthest galaxies."
From Science Magazine
comes this report about a blast from the past, a giant radio signal. No signs of intelligence in the signal, though. However, what would Art Bell say??

The Themis instruments on the Mars Odyssey, in orbit around Mars, shows what seem to be cave entrances. A number of proponents of manned exploration/settlement of Mars have long speculated about these features and hope to turn them into living and work quarters. However, these seem to be at high altitutes and not around the Martian equator as many have hoped. You can also see the Journal of Geophysical Research Letters for more information. See also the Mars Society's proposal or the Powerpoint proposal by Gus Frederick of Silverton, Oregon.

Antimatter molecule could lead to ultra-powerful laser - tech - 18 September 2007 - New Scientist Tech
Just in time for talk like a pirate day! A pirate could sure make use of this short-lived anti-matter ray. This is from the magazine New Scientist.
"Antimatter molecule could lead to ultra-powerful laser
An exotic molecule built from electrons and antimatter is being touted as a route to powerful gamma-ray lasers.
An electron can hook up with its antiparticle, the positron, to form a hydrogen-like atom called positronium (Ps). It survives for less than 150 nanoseconds before it is annihilated in a puff of gamma radiation. It was known that two positronium atoms should be able to bind together to form a molecule, called Ps2, and now David Cassidy and Allen Mills from the University of California, Riverside, have made that happen. First, they trapped positrons in a thin film of porous silica. Those positrons captured electrons to form positronium atoms, and the pattern of decay rates signalled that some of these atoms had teamed up to form Ps2 (Nature, DOI: 10.1038/nature06094)."

APOD: 2007 August 27 - Huge Void Implicated in Distant Universe
"Explanation: What has created this huge empty volume in the universe? No one is yet sure, and even the extent of the estimated billion-light year void is being researched. The void is not a hole in space like a black hole, but rather a vast region of the universe that appears to be mostly devoid of normal matter and even dark matter. The void is still thought to contain dark energy, though, and is clearly traversable by light. The void's existence is being postulated following scientific curiosity about how unusually cold spots came to appear on WMAP's map of cosmic microwave background (CMB) radiation. One possibility was that this CMB region was not actually very cold but light from the spot somehow became more cosmologically redshifted than normal along the way.'
From NASA's Astronomy Picture of the Day. That void is like my appetite is most of the time!! I still don't grasp the concept of Dark Energy or Dark Matter. Okay, maybe dark matter, but dark energy! These slow down the expansion of the universe. Also, see the Pioneer Anomaly.
Two Pioneer spacecraft, launched 30 years ago on a mission to the outer solar system, are now leaving the immediate vicinity of the solar system. While they are not yet in interstellar space, their speeds and trajectories do not match Newtonian and Einsteinian predictions. Either there is something new in gravity or problems in measurements or math. See the link for some new thoughts on the matter.

Bitter winters blighted much of the northern hemisphere for decades in the second half of the 17th century. The French army used frozen rivers as thoroughfares to invade the Netherlands. New Yorkers walked from Manhattan to Staten Island across the frozen harbour. Sea ice surrounded Iceland for miles and the island's population halved. It wasn't the first time temperatures had plunged: a couple of hundred years earlier, between 1420 and 1570, a climatic downturn claimed the Viking colonies on Greenland, turning them from fertile farmlands into arctic wastelands."

Those Crazy Japanese
Greetings, campers! Yes, I am back. I thought no one was reading this, but occasionally someone does. Besides, it is a good way for me to keep track of my Internet wanderings. In light of the talk about space elevators, one cannot ignore the dreams of one Japanese construction company. The XSEED 4000 is a Utopian skyscraper modeled after Mt. Fuji and would be 4000m tall! Well, we all have to dream! Also see links to other proposed super buildings by clicking here! Keep those cards and letters coming. Please comment or email. I have to use to verification system to stop the pesky robots that cruise blogs and leave messages offering me mortgages and other less mundane things.

Technology Review: Mining for Cheap Flights
Technology Review: Mining for Cheap Flights: "On a flight to his brother's wedding in 2001, Oren Etzioni discovered that the people sitting next to him had bought their tickets later than he did, yet had paid less. For some, this could have been an infuriating revelation, but Etzioni didn't get mad; as a professor of computer science and engineering at the University of Washington, in Seattle, he got inspired. 'I thought, 'Why don't I collect historical data [on airfares] and use that to anticipate ticket prices?''"

Similarities in making solar chips and microchips
Friday, March 23, 2007
The Oregonian
Many Oregon chip-industry veterans possess skills that readily transfer to the solar business, piquing the excitement of state economic officials.
Five categories of production-operator positions common to both industries:
Crystal growing: The same process of growing silicon-crystal ingot is used in both industries, differing mainly in the purity of the polysilicon raw material. The steps: melting and chemically doping polysilicon, dipping seed crystal, extracting ingot from molten polysilicon. Solar usually grows ingots of smaller diameter, but three times longer (about 3 feet).
Grinding: In both industries, ingots are ground to remove surface irregularities. The major differences are grinding specifications and speeds.
Wafer slicing: Both industries use similar wire saw machines to cut ingot into wafers. Solar wafers are about as thin as a business card; chip wafers are about three times as thick. Using longer ingot, the solar business cuts about four times as many wafers at a time.
Diffusion: Both industries turn wafers into an electrical device with a positive and negative side. Typically, phosphorus is diffused into the wafers. The process forms an oxide layer, which must be removed.
Printing: Many solar businesses use a screening technique to print a grid pattern on both sides of cells. In the chip industry, photolithography is extremely complex -- much more so than in solar.

WAVE ENERGY
Previous posts here dealt with wave energy projects off of the
Oregon Coast
The above is a link to an Oregon government website on the current wave projects. Also, see my November 2005 posts by on Oregon wave energy by clicking here.
There was also a recent story on a BBC technology website about a different kind
of wave project off the coast of Portugal named Pelamis. The Pelamis is a sea snake, something
the new Portugal device resembles. The European Union has an aggressive alternative
energy program that includes wave energy. Click here for a link to the BBC World Podcast.
Speaking of energy, it appears that while Al Gore refused to rise to the bait at the Oscar
Awards ceremony and announce for President, former President Jimmy
Carter is bugging his so much about running, Gore is hiding from his calls. See a related story here.
On a closing note, I have hardly been keeping this blog up. I know, however,
that there are some readers. Please comment.

Movie Review: Children of Men
The above review is from the Hollywood Reporter. I do not totally agree. I am a fan of the author of the original book, P.D. James. I really liked the book. I now see why all of the ads for the movie did not tout the author. She probably did not want them to. As a movie, it was pretty good, but not at all what I remember the book to be. I was disappointed.
Now, going to SF books (note: P.D. James is a high class mystery writer and not a SF writer), be sure and read books by the Australian author Greg Egan. He is a computer programmer and holds a math degree from the University of Western Australia.
So far, I have read Teranesia , a very good book based on genetics. I tried reading Schild's Ladder, but it was too highly mathematical for my meager mind. I am now reading Diaspora, a book about computer evolution, consciousness and intelligence. Be sure and see Egan's web page at http://gregegan.customer.netspace.net.au/
