Analysis of Kramnik-Svidler, Tal Memorial Chess Tournament 2009 round 3















I have just completed some analysis of the third round chess  game
between former World Chess Champion Vladimir Kramnik and Peter Svidler, from the 2009 Tal Memorial Chess tournament, and posted the analysis below on page one of my blog using the program Chess Viewer Deluxe. I used the World's strongest chess program, Deep Rybka 3 to assist me in my analysis of this game.  I hope you enjoy playing through this analysis.Playing through a game played by chess professionals in which the Grunfeld Defense was used, it always a very interesting and educational experience, because the Grunfeld defense is a hypermodern opening, involving lots of piece play.

"Vladimir Kramnik  (photo above on the left)  was Classical World Chess Champion from 2000 to 2006, and undisputed  World Chess Champion from 2006 to 2007. In October 2000, he defeated Garry Kasparov  in a match played in London, and became the Classical World Chess Champion. In late 2004, Kramnik successfully defended his title against challenger  Peter Leko  in a drawn match  played in Brissago, Switzerland."


In October 2006, Kramnik, the Classical World Champion, defeated reigning FIDE World Champion Veselin Topalov  in a unification match, the  World Chess Championship 2006. As a result Kramnik became the first undisputed World Champion, holding both the FIDE and Classical titles, since Kasparov split from FIDE in 1993."
"In 2007, Kramnik lost the title to Viswanathan Anand,   who won the World Chess Championship tournament ahead of Kramnik. He challenged Anand at the World Chess Championship 2008  to regain his title, but lost."
(source:http://en.wikipedia.org/wiki/Vladimir_Kramnik) Kramnik's official website is at: http://www.kramnik.com/. Kramnik is currently the fifth-highest-rated chess player in the world with an elo of 2772. (Source: http://ratings.fide.com/top.phtml?list=men)


Peter Svidler (photo above on the right)  is a multi-year time of the Russian Chess Championship.He loves to play complicated games "On the November 2009 FIDE  rating list he has an ELO rating of 2738, making him the thirteenth-highest-rated player  the world. Svidler is a  exponent of Fischer Random Chess  (also called Chess960). He won the first edition of the Chess960 Open held in Mainz, Germany. At the 2003 Mainz Chess Classic, he became Chess960 World Champion by defeating Peter Leko  in an eight-game match. He successfully defended his title twice, defeating Levon Aronian in 2004 and Zoltan Almasi in 2005, before losing it to Aronian in 2006." (source:http://en.wikipedia.org/wiki/Peter_Svidler) .

Tal Memorial 2009:Round 5 results and standings,round 6 pairings

Here are the results from round 5 of the Tal Memorial Chess Tournament being played in Moscow. One game of the four played today had a decisive result, in it Kramnik defeated Svidler with Kramnik having the white pieces. Kramnik began the game by playing the Queen's Gambit, and as usual Svidler played his favorite Grunfeld Defense. The game was very complex, and Svidler made some mistakes which cost him the game.

Carbon trading: How to save a forest

Projects in Madagascar could provide a model for stemming deforestation. But first these efforts must deal with the poverty and political upheaval that threaten forests, reports Anjali Nayar.


 The photo, taken by Rhett A. Butler shows Deforested patches near Makira

"We record all the numbers — the trees, the dead wood and the leaf litter," says Ratelolahy, looking up from his clipboard. "And then back in the capital, poof, the computer calculates the amount of carbon in the forest."

"Over the years, Ratelolahy has watched subsistence farmers slash and burn away the margins of the forest to grow rice. And he has come across gangs pillaging the forest for rosewood, ebony and quartz. "It looks as though bombs have fallen on the place," says Ratelolahy about the ransacked areas."


"Makira is on the front line of the war being waged to slow global warming. As one of Madagascar's largest forests, it stores millions of tonnes of carbon. But as in most forests in the country, that carbon is being rapidly released to the atmosphere as trees are cut down for agriculture, timber, mining and firewood. The WCS, in collaboration with the government and other organizations, is hoping to protect Makira and, at the same time, generate money to support local communities by 'renting' the forest to rich countries."

"The idea is that wealthy nations could meet their greenhouse-gas emissions targets in part by buying carbon credits from developing countries such as Madagascar. The poorer nations could earn money by keeping their forests standing, rather than cutting them down."


"This strategy, known as reducing emissions from deforestation and forest degradation (REDD), is one of the topics up for discussion at the UN climate-change summit in Copenhagen this December. Countries will negotiate whether REDD should be included in the climate deal that takes over from the Kyoto Protocol when it expires in 2012."

"Proponents for REDD say that this mechanism is key to cutting deforestation, which accounts for around 20% of greenhouse-gas emissions. It is also estimated that REDD could generate billions of dollars each year for forest conservation, far more than is currently spent. Hoping to cash in on the future market, projects have burgeoned around the developing world, with those in Madagascar being some of the earliest to take shape.

"The projects are also helping to establish technical standards and methodologies for carbon accounting.
REDD projects must keep the promised forests standing. To succeed, this means addressing the poverty and political instability in developing countries that often lead to deforestation. These problems are particularly acute in Madagascar, where a coup earlier this year disrupted conservation efforts and raised questions about the future of REDD there."

"Madagascar is one of the wealthiest countries in terms of biodiversity, but its people are among the world's poorest. Around 85% of the population live below the World Bank's $2-a-day poverty line and most rely heavily on the country's natural resources."


"The hilly countryside is scarred by slash-and-burn agriculture, locally known as tavy. Once people fully exploit the fertile river valleys, they head uphill, clearing the forests to cultivate rice, the country's staple food. These rain-fed fields are harvestable for only a few seasons before productivity drops and villagers clear new land for their crops."

"Estimates of Madagascar's original forested areas vary widely, but some studies suggest that trees once blanketed 90% or more of the island. Since aerial photographs of the country were taken in the 1950s, forests have decreased by more than 40% and by about 2005, they covered only around 15% of the country.
Over the past two decades, deforestation has been decreasing slowly with the creation of protected areas. Grants from the World Bank and USAID helped Madagascar to become one of the first countries in Africa to develop and implement a national environmental action plan."

"By 2000, the nation had protected 17,000 square kilometres of forest, mainly as national parks. But further expansion of the park system stalled because the funding stream from donors dried up. So, in 2001, the government teamed up with non-governmental organizations and started exploring the idea of selling carbon credits from their forests. "It was clear that there was a carbon market emerging and that avoided deforestation could be a very powerful way of protecting forests in Madagascar," says Frank Hawkins, vice-president for Africa and Madagascar of Conservation International in Washington DC. Hawkins was part of the team that popularized REDD on the island."

"The efficacy of a REDD project depends on how much carbon the project will prevent from being released in the absence of protective measures. Calculating that number requires first measuring the current carbon content of a forest — as Ratelolahy and his crew are currently doing — and then projecting future deforestation rates with and without the project in place. The WCS is doing that by using past satellite imagery and making forecasts that account for factors such as the proximity of the forest to roads and villages.
A study in 2004, conducted in collaboration with the non-profit organization Winrock International in Little Rock, Arkansas, estimated that the annual rate of deforestation was 0.15% in Makira. The analysis projected that the rate would rise to 0.2% a year by 2034 without any intervention. But with the REDD project in place, the deforestation rate would slow to about 0.07%. These preliminary estimates indicated that the 30-year project would avert the release of more than 9 million tonnes of CO2 equivalent, similar to taking 2 million cars off the road in the United States for a year."




"It could be years before carbon payouts come through a UN-regulated REDD system. The WCS and its donors have already spent $1.9 million to establish the Makira REDD project, and the support going to local communities will increase when the carbon funds arrive. But for the people of Andaparaty, the support can't come soon enough. "People are wondering where the money from REDD is, or if it will ever come," says Ratelolahy."

"Political unrest in Madagascar makes the future of REDD projects there even less certain. On 17 March this year, following two months of protest, the 35-year-old mayor of Antananarivo, Andry Rajoelina, took the presidency in a military-backed coup."
“Because of the instability people feel more liberated, which translates into more exploiting.”


"The ensuing political instability caused a surge in illegal wildlife trafficking, mining and logging activities, threatening the country's forests. "Because of the political instability, people feel liberated, which translates to more exploiting," says Haja Salava, the director of Masoala National Park, adjacent to Makira.
Armed gangs are ravaging the northeastern region for its valuable rosewood and ebony. The park rangers and community members who have tried to impede the illegal trade have been threatened with death, says Salava.
In the past few months, thousands of illegal loggers have been raiding his national park, Salava estimates. In his dilapidated office in the regional capital Maroantsetra, he scrolls through his monthly reports to the government. The pages are a collage of photos of men posing with freshly cut wood. The loggers aren't afraid of being caught because, despite Salava's repeated calls for assistance, the government police do not stop the trade, he says. "It's a free-for-all."
Mariot Rakotovao, who led the country's Ministry of the Environment and Forests at the time, said his department had ramped up police patrols in the region and had fined illegal loggers.

Scientists unearth evidence of centuries-old aftershocks

Some interesting new research concerning the process of what occurs before and after an earthquake to the earth was revealed today. According to a news article at the following website: http://www.independent.co.uk/news/science/scientists-unearth-evidence-of-centuriesold-aftershocks-1814689.html, it has been revealed that

Written by Steve Conner
"Some of the most violent earthquakes that have occurred unexpectedly in places with no recent record of tremors may be the aftershocks of previous earthquakes that took place decades or even centuries ago, scientists have discovered.Earthquakes usually occur at the boundary of two or more tectonic
plates – the massive chunks of the earth’s crust that grind slowly against one another. However, they can also occur many hundreds of miles from a fault line and it is these earthquakes that scientists believe may be the result of long aftershocks rather than background seismic activity."

"A laboratory study that tested how tectonic faults work has found that the further away an earthquake is from such fault line, the stronger the likelihood that it could be the long aftershock of a previous earthquake that has taken many years to make itself felt in terms of a second series of violent ground movements."

Why are athletes above the law?

Today, another video, in which an athlete commits criminal offences against another player was released to the world. No this did not happen in a men's North American football or  hockey game, but rather, it happened in a women's college soccer game!


"A U.S. college soccer player who was once rookie of the year has been suspended indefinitely for punching, kicking, and pulling the hair of an opposing player during a game.
Elizabeth Lambert, 20, a defender who played for the women's team at the University of New Mexico, was suspended on Friday.
In a viral video that has already received more than 2 million hits in just three days on Youtube, Lambert is shown pulling another player to the ground by her ponytail in Thursday's game against Brigham Young University in Utah.
Lambert has been banned from practices, games, and training sessions.
Lambert has apologized, saying "I let my emotions get the best of me in a heated situation."
"I take full responsibility for my actions and accept any punishment felt necessary," she said.
Darnell Dickson, the sports editor of the Provo Daily Herald in Utah told CTV News Channel that there is no rivalry or history of bad blood between the two teams, and Lambert has no history of aggressive playing.
He said the referee will now have to answer for his officiating. Lambert was given just a yellow card in the 76th minute, apparently for tripping, but her other actions went ignored.
"I think the official does need to be held accountable," he said."

Watch the video, do you think she deserved more than a suspension?





What is with athletes? They are pampered by their parents, their coaches, their universities, their clubs, and they have come to believe they can do anything they want to during a game, or even off of the field. This soccer incident comes on the heels of an incident in an American College football game, in which one player punched an opponent after the game:



I have simply stopped watching all sports on television. These athletes are out of control, they think they can do anything on or off the field, regardless of whether their actions are against the law or not. The sad part of this situation, is that impressionable children and even adults, see this kind of behavior, and begin to copy it or begin to believe that  they can do anything they want to, to anyone they want to.   Even though in the second video, this University of Oregon player punched the Boise State player, I found out today reading the news that the University of Oregon has reinstated the player who punched the Boise State player in the video.!!! After the incident ,the Oregon player had been kicked off the team. Now for some reason the coach of the University of Oregon thinks that his player has had enough punishment. Regardless of what happened during the interaction of the Boise State player and the Oregon player, the Oregon player had no right to take the law into his own hands. Sadly,this is type of behavior is happening more and more in the world. How long will athletes be able to be above the laws of their countries? How many more children will learn to commit crimes by watching pro athletes or reading about the behavior of these athletes?  I am not conservative in myviews at all!  I am very liberal in my thinking, and in truth, my father was a professional athlete for part of his working career!   If I think there is something wrong with the way athletes are behaving on and off the playing field,then there must be a problem.


Here are some links to some websites which describe athletes who think they are above the law:

NASA Instruments Reveal more water on the moon than previously thought

On September 24th,2009 NASA released the following image which indicated that water existed on the Moon:



Image:Shows water on a crater on the moon

NASA then released a news article concerning this find:

"NASA scientists have discovered water molecules in the polar regions of the moon. Instruments aboard three separate spacecraft revealed water molecules in amounts that are greater than predicted, but still relatively small. Hydroxyl, a molecule consisting of one oxygen atom and one hydrogen atom, also was found in the lunar soil. The findings were published in Thursday's edition of the journal Science. "

"NASA's Moon Mineralogy Mapper, or M3, instrument reported the observations. M3 was carried into space on Oct. 22, 2008, aboard the Indian Space Research Organization's Chandrayaan-1 spacecraft. Data from the Visual and Infrared Mapping Spectrometer, or VIMS, on NASA's Cassini spacecraft, and the High-Resolution Infrared Imaging Spectrometer on NASA's Epoxi spacecraft contributed to confirmation of the finding."

"The confirmation of elevated water molecules and hydroxyl at these concentrations in the moon's polar regions raises new questions about its origin and effect on the mineralogy of the moon. Answers to these questions will be studied and debated for years to come.

"Water ice on the moon has been something of a holy grail for lunar scientists for a very long time," said Jim Green, director of the Planetary Science Division at NASA Headquarters in Washington. "This surprising finding has come about through the ingenuity, perseverance and international cooperation between NASA and the India Space Research Organization."

"From its perch in lunar orbit, M3's state-of-the-art spectrometer measured light reflecting off the moon's surface at infrared wavelengths, splitting the spectral colors of the lunar surface into small enough bits to reveal a new level of detail in surface composition. When the M3 science team analyzed data from the instrument, they found the wavelengths of light being absorbed were consistent with the absorption patterns for water molecules and hydroxyl."

"For silicate bodies, such features are typically attributed to water and hydroxyl-bearing materials," said Carle Pieters, M3's principal investigator from Brown University, Providence, R.I. "When we say 'water on the moon,' we are not talking about lakes, oceans or even puddles. Water on the moon means molecules of water and hydroxyl that interact with molecules of rock and dust specifically in the top millimeters of the moon's surface."

"The M3 team found water molecules and hydroxyl at diverse areas of the sunlit region of the moon's surface, but the water signature appeared stronger at the moon's higher latitudes. Water molecules and hydroxyl previously were suspected in data from a Cassini flyby of the moon in 1999, but the findings were not published until now."

For additional information and images from the instruments, visit:

http://www.nasa.gov/topics/moonmars

For more information about the Cassini mission, visit:
http://www.nasa.gov/cassini

Now NASA has released new information which indicates  that there  is more water on the moon in more locations than originally thought, a discovery that may bolster NASA's long-held goal of setting up an outpost there.





"One ton of the moon's surface -- in which the water's ingredients are held -- could yield as much as 32 ounces, or one This most recent information is far more precise than any previous data, Mustard said. Previous measurements were "the size of Texas, say, and now are the size of Providence."
"We find it (water) distributed more broadly," he added., of water, according to three reports from research teams who studied data from three spacecrafts."
"Although that amount isn't large, said geological sciences professor Jack Mustard, the findings show "there are ways you could convert these amounts of water into higher amounts" that could support human activity."
"The water was discovered in rocky environments and in craters, Mustard said."
"It's in more places and in different places than were inferred previously," he said.
"Since the Apollo missions began in the 1960s, scientists have believed the moon was virtually dry. Only trace amounts of water were found in rocks and soil brought back to Earth, and that water may have resulted from contamination during the retrieval process, scientists said."



So where can we sign up to be the first humans to exist on a colony on the moon?

Great Whites hang out in Pacific's 'shark cafe'


  


Photo by Terry Goss, copyright 2006. Taken at Isla Guadalupe, Mexico, August 2006 Source:http://simple.wikipedia.org/wiki/File:White_shark.jpg

 

Some fascinating new research has been announced concerning the behavior of Great White Sharks.Scientists at one time thought Great White sharks were loners exclusively.However, new research indicates this theory is incorrect. According to an article posted online:


"Great Whites may be loners, but the ocean's most feared predators also hang out together between Mexico and Hawaii at a deep sea watering hole known as the "White Shark Cafe," a study reveals.
No animals inspire more fascination and frissons, but scientists admit to knowing precious little about how the endangered Great Whites get around and get it on as they navigate the globe's oceans."

"Like other open water sharks prized for their meat -- and, in Asia, especially for their fins -- the magnificent hunting machines are threatened with extinction, according to experts.

"The new study identifies a distinct population and a major new genetic grouping of the Great White in the eastern Pacific, only the third such "clade" ever found.
The other two concentrations of Carcharodon carcharias are off the coast of South Africa, and in the waters between Australia and New Zealand."

"It had long been assumed shark species at the top of the ocean food chain that roam the high seas looking for food and mates did so almost randomly.
But using satellite tagging, acoustic monitoring of shark "hot spots" and genetic samples, a research team led by Barbara Block of Stanford University found -- to their surprise -- that the eastern Pacific's Great Whites are real homebodies.
Over an eight year period, nearly 100 sharks were electronically tagged, and even more had tissue samples taken by scientists working from a ship."

"Not only do the sharks consistently migrate along the same paths, they stick to a schedule too.
Between August and December, the Great Whites -- which can grow up to six metres (20 feet) and three tonnes -- stalk waters off the coast of central and northern California, feasting on seals and sea lions.
Their preferred hunting grounds in this area are known as the "red triangle", notes the study, published in the British journal Proceedings of the Royal Society B."
"Starting in January, they head for the deep blue around Hawaii some 4,000 kilometers (2,500 miles) to the west, where they are found in largest numbers between April and July."
"But some -- especially males -- loiter at a halfway point known as the "White Shark Cafe", with females coming and going for what scientists presume is a bit of shark intimacy."

"The new findings will help conservation efforts, the study concludes: "The population's fidelity to predictable locations offer clear population assessment, monitoring and management options."
A third of the world's open water sharks -- including the Great White and hammerhead -- face extinction, according to the largest ever shark survey, completed earlier this year by the International Union for the Conservation of Nature (IUCN)."
"For decades, significant numbers of sharks -- including blue and mako -- have perished as "by-catch" in commercial tuna and swordfish operations.
More recently, the soaring value of shark meat has prompted some of these fisheries to target sharks as a lucrative sideline."
"Europe is the fastest growing market for meat from the porbeagle and another species, the spiny dogfish.
Around 100 million sharks are caught in commercial and sports fishing every year, and several species have declined by more than 80 percent in the past decade alone, according the International Fund for Animal Welfare (IFAW)."


"Satellite tracking systems and acoustic sensors are giving researchers insights into the behavior and lifestyles of some very elusive animals in the ocean, including the fabled white shark."

"Researchers from several institutions, including Stanford University, have joined their efforts in a Census of Marine Life project called Tagging of Pacific Predators (TOPP). Since the project began in 1999, they have attached more than 3,000 tags to sharks, seals, whales, tunas, squids, turtles, albatross and more. For the first time, these TOPP researchers are getting a glimpse of a pelagic ecosystem from the California Current to the North Pacific at daily, seasonal and yearly time scales."
"Along with the white shark, the TOPP researchers also have been studying the routes and habits of two cousins of the white shark: the salmon shark, whose range extends from the glaciers of Alaska down to Baja California, where it crosses over the white sharks' territory along the continental coast, and the mako shark, which resides along the continental shelf off California. The team also has tagged thresher sharks and blue sharks."
"Sharks are a vital part of oceanic ecosystems. As the top predators in the food chain, they regulate the populations of the species below them. If shark populations get in trouble, it can trigger a cascading effect all the way down the food chain. The TOPP team has used several distinct tag technologies to get a simultaneous view of how these sharks divide up the ocean turf."
"Salvador Jorgensen, a postdoctoral researcher at Stanford University's Hopkins Marine Station and the Monterey Bay Aquarium, is part of the group that has been tagging and monitoring white sharks, more popularly known as great white sharks."
"Jorgensen discussed the team's work Sunday, Feb. 17, at the American Association for the Advancement of Science (AAAS) annual meeting in Boston."
"What they have found has opened up a whole new vista in the white shark's world. It turns out white sharks are quite the sightseers.
"Jorgensen and his colleagues have tagged more than 100 white sharks along the central California coast. Home to numerous seal and sea lion rookeries, the area along the continental shelf is practically one long lunch counter for the white sharks. But in spite of the fine dining available there, the sharks exhibit an urge to roam."
"Through tracking the tagged sharks, the TOPP team has found two distant destinations that the sharks favor, both of which they visit on a regular, annual travel timetable. Each winter the white sharks head out from the California coast, with some going to the Hawaiian Islands. Most, however, head to another hotspot, out in the middle of the Pacific Ocean. This second location is roughly 1,300 miles from the mainland—about half the distance to Hawaii—and a few hundred miles to the south of the direct route to the islands. Dubbed "the white shark café" by the researchers, just what the attraction is out there remains something of a puzzle. But what is clear is that all the sharks that summer along the California coast show remarkable fidelity; when they return to the mainland, they head for the same local neighborhoods that they favor every summer."
"These animals appear again and again at very specific areas," Jorgensen said. Despite the sharks' ability to move through the ocean to wherever they please, they stick to consistent routes and destinations. It is a striking finding, because white sharks are found off South Africa and Australia, in addition to the West Coast of North America, but what the TOPP team and other researchers have found is that the populations do not appear to mix. New data presented by the TOPP team indicate that even between Pacific Ocean basin populations there are genetic differences. This means that white sharks, at least the females, have maintained long term isolation in the Eastern Pacific."
"This is really important in terms of management, so that management can focus on these population units," Jorgensen said. "And this really sets the stage for us to census the population, now that we know it is a confined population in the eastern Pacific."
There is another group of white sharks that tend to congregate near Guadalupe Island, offshore from Baja California, south of the California population that the TOPP team has been studying, but it is not yet clear whether they are distinct from the central California group.
Most of the tags used by the TOPP researchers have been electronic tags that are monitored by satellite. Those tags provide location data when the sharks are on the high seas. The other tags are acoustic tags; sensors installed along the California coast pick up the signal whenever one of the tagged sharks swims by.
"The TOPP program maintains a live access server that gives regular updates on the locations of the sharks that have been tagged. "My favorite activity is to wake up and check where the sharks are," said Barbara Block, the Charles and Elizabeth Prothro Professor in Marine Sciences at Hopkins Marine Station."
"Block is one of the researchers on the TOPP team and Jorgensen is doing postdoctoral research in Block's lab. TOPP partners in the shark research consortium include scientists from the University of California-Davis, the National Oceanic and Atmospheric Administration, PRBO and the Pelagic Shark Research Foundation."

A glimpse of the future: Robots aid Japan's elderly residents

According to a news story written by Calum MacLeod of USA Today,

"It looks like a scene from Robocop or one of the Terminator movies: A human steps into a sleek robot suit and is miraculously transformed, suddenly capable of astonishing feats of strength.

But this is no sci-fi film — it's a promotional video by Cyberdyne, a Japanese electronics company. It shows an elderly male patient with Parkinson's disease being strapped into a robotic skeleton that, using sensors attached to the wearer's skin, reacts to nerve impulses and moves its "arms" and "legs" accordingly.

The robotic suit, known as the Hybrid Assisted Limb (or HAL), is designed to boost its wearer's strength by a multiple of 10. In July, it allowed the patient at the Seiko En nursing home in Tsurugashima, Japan, to walk for the first time in two years, Cyberdyne CEO Yoshiyuki Sankai says.

"I was surprised," Sankai admits. "I expected him to stand up, but not to walk."

To read the remainder of this article and to view the video aboutHAL  talked about above please click on this link:

--------------------------------------------------------------------------------------------

It is great to see that scientists are using their creativity and talents to help people in need. The media seems to inundate  us with news stories which emphasize  the negative uses of technology by humans!

How does HAL work you ask?

The answer is:


  • When a person attempts to move, nerve signals are sent from the brain to the muscles via motoneuron, moving the musculoskeletal system as a consequence. At this moment, very weak biosignals can be detected on the surface of the skin. "HAL" catches these signals through a sensor attached on the skin of the wearer. Based on the signals obtained, the power unit is controlled to move the joint unitedly with the wearer's muscle movement, enabling to support the wearer's daily activities. This is what we call a 'voluntary control system' that provides movement interpreting the wearer's intention from the biosignals in advance of the actual movement. Not only a 'voluntary control system' "HAL" has, but also a 'robotic autonomous control system' that provides human-like movement based on a robotic system which integrally work together with the 'autonomous control system'. "HAL" is the world's first cyborg-type robot controlled by this unique Hybrid System.
  • "HAL" is expected to be applied in various fields such as rehabilitation support and physical training support in medical field, ADL support for disabled people, heavy labour support at factories, and rescue support at disaster sites, as well as in the entertainment field.

University of Alberta Physicist identifies a young neutron star

A physicist from the University of Alberta in Edmonton  is part of a team that has identified a neutron star left over from a supernova first observed over 330 years ago.


Physicist Craig Heinke (pictured)

and his associate Wynn Ho at the University of Southampton, U.K., both agree that the remnant of the supernova Cassiopeia A is a very young neutron star, 20 times heavier than the sun, but only 20 kilometres wide.

Here is a photo of the   The supernova remnant Cassiopeia A as seen by the Chandra X-Ray Observatory. The blue dot in the centre of the image is identified as a young neutron star. (Source of image: NASA/CXC/Southampton/W. Ho)




A neutron star can be defined as "  a massive star which  goes through a supernova and all remaining particles within the star collapse." (source:http://physics.about.com/od/glossary/g/neutronstar.htm).The  term "supernova"  refers to " the death explosion of a massive star, resulting in a sharp increase in brightness followed by a gradual fading. At peak light output, supernova explosions can outshine a galaxy. The outer layers of the exploding star are blasted out in a radioactive cloud. This expanding cloud, visible long after the initial explosion fades from view, forms a supernova remnant (SNR)." (source:http://space.about.com/od/glossaries/g/supernova.htm).



"The majority of a neutron star, according to predictive models, is composed of neutrons, hence the name. Sir James Chadwick discovered the neutron as an elementary particle in 1932, earning the 1935 Nobel Prize in Physics for this work. Astronomers Walter Baade and Fritz Zwicky proposed the existence of a neutron star as early as 1933. In their prediction, the release of gravitational binding energy in the formation of a neutron star is what powers the visible supernovae. A typical neutron star is between 30,000 to 70,000 times smaller than the sun, but much more massive, reaching up to over twice the mass of the sun.  (source:http://physics.about.com/od/glossary/g/neutronstar.htm)

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed

Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein

Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia

A person's true wealth is the good he or she does in the world. - Mohammed

The best way to find yourself, is to lose yourself in the service of others. - Ghandi

The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller

Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165
