Higgs boson

Higgs boson

particle detector

– I follow a lot of stuff and one area I like to look in on occasionally is physics.  

– The biggest story there,of course, is the decades long conundrum of how to resolve General Relativity and Quantum Mechanics to yield a Theory of Everything.   So far as I know, the String Theorists and the Quantum Loop Gravity folks are still pounding away on those doors but they haven’t budged.

– But there’s another area that’s looking like it is about to yield to our inquiries and that is the ongoing efforts at CERN to locate the last undetected particle in the Standard Model’s table of fundamental particles; the Higgs Boson.

CERN‘s particle accelerator is thought to be able to smash particles together at energy level sufficient to resolve the Higgs Boson and everyone who follows this stuff is quite excited.   As, as always, when the particle smashers take us into new energy realms, there’s always a good chance that we’ll see something new that could upset our previous best guesses at how things work – and that’s exciting.

– Most folks how no idea what the Higgs boson is and I’m the first to admit that it is all a bit obscure.   But, I found a nice cartoon that tells the story in a way that interesting and entertaining.

Let’s just say it: The Republicans are the problem.

Monday, April 30th, 2012

– For my American friends … because politics have become such fun there.

– Dennis

– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –

By Thomas E. Mann and Norman J. Ornstein, Published: April 28 in the Washington Post

Rep. Allen West, a Florida Republican, was recently captured on video asserting that there are “78 to 81” Democrats in Congress who are members of the Communist Party. Of course, it’s not unusual for some renegade lawmaker from either side of the aisle to say something outrageous. What made West’s comment — right out of the McCarthyite playbook of the 1950s — so striking was the almost complete lack of condemnation from Republican congressional leaders or other major party figures, including the remaining presidential candidates.

It’s not that the GOP leadership agrees with West; it is that such extreme remarks and views are now taken for granted.

We have been studying Washington politics and Congress for more than 40 years, and never have we seen them this dysfunctional. In our past writings, we have criticized both parties when we believed it was warranted. Today, however, we have no choice but to acknowledge that the core of the problem lies with the Republican Party.

The GOP has become an insurgent outlier in American politics. It is ideologically extreme; scornful of compromise; unmoved by conventional understanding of facts, evidence and science; and dismissive of the legitimacy of its political opposition.

When one party moves this far from the mainstream, it makes it nearly impossible for the political system to deal constructively with the country’s challenges.

“Both sides do it” or “There is plenty of blame to go around” are the traditional refuges for an American news media intent on proving its lack of bias, while political scientists prefer generality and neutrality when discussing partisan polarization. Many self-styled bipartisan groups, in their search for common ground, propose solutions that move both sides to the center, a strategy that is simply untenable when one side is so far out of reach.

It is clear that the center of gravity in the Republican Party has shifted sharply to the right. Its once-legendary moderate and center-right legislators in the House and the Senate — think Bob Michel, Mickey Edwards, John Danforth, Chuck Hagel — are virtually extinct.

The post-McGovern Democratic Party, by contrast, while losing the bulk of its conservative Dixiecrat contingent in the decades after the civil rights revolution, has retained a more diverse base. Since the Clinton presidency, it has hewed to the center-left on issues from welfare reform to fiscal policy. While the Democrats may have moved from their 40-yard line to their 25, the Republicans have gone from their 40 to somewhere behind their goal post.

What happened? Of course, there were larger forces at work beyond the realignment of the South. They included the mobilization of social conservatives after the 1973Roe v. Wadedecision, the anti-tax movement launched in 1978 by California’s Proposition 13, the rise of conservative talk radio after a congressional pay raise in 1989, and the emergence of Fox News and right-wing blogs. But the real move to the bedrock right starts with two names:Newt Gingrich and Grover Norquist.

From the day he entered Congress in 1979, Gingrich had a strategy to create a Republican majority in the House: convincing voters that the institution was so corrupt that anyone would be better than the incumbents, especially those in the Democratic majority. It took him 16 years, but by bringing ethics charges against Democratic leaders; provoking them into overreactions that enraged Republicans and united them to vote against Democratic initiatives; exploiting scandals to create even more public disgust with politicians; and then recruiting GOP candidates around the country to run against Washington, Democrats and Congress, Gingrich accomplished his goal.

Ironically, after becoming speaker, Gingrich wanted to enhance Congress’s reputation and was content to compromise with President Bill Clinton when it served his interests. But the forces Gingrich unleashed destroyed whatever comity existed across party lines, activated an extreme and virulently anti-Washington base — most recently represented by tea party activists — and helped drive moderate Republicans out of Congress. (Some of his progeny, elected in the early 1990s, moved to the Senate and polarized its culture in the same way.)

Norquist, meanwhile, founded Americans for Tax Reform in 1985 and rolled out his Taxpayer Protection Pledge the following year. The pledge, which binds its signers to never support a tax increase (that includes closing tax loopholes), had been signed as of last year by 238 of the 242 House Republicans and 41 of the 47 GOP senators, according to ATR. The Norquist tax pledge has led to other pledges, on issues such as climate change, that create additional litmus tests that box in moderates and make cross-party coalitions nearly impossible. For Republicans concerned about a primary challenge from the right, the failure to sign such pledges is simply too risky.

Today, thanks to the GOP, compromise has gone out the window in Washington. In the first two years of the Obama administration, nearly every presidential initiative met with vehement, rancorous and unanimous Republican opposition in the House and the Senate, followed by efforts to delegitimize the results and repeal the policies. The filibuster, once relegated to a handful of major national issues in a given Congress, became a routine weapon of obstruction, applied even to widely supported bills or presidential nominations. And Republicans in the Senate have abused the confirmation process to block any and every nominee to posts such as the head of the Consumer Financial Protection Bureau, solely to keep laws that were legitimately enacted from being implemented.

Fukushima to Burn Highly-Radioactive Debris

Sunday, April 29th, 2012

Japan is Poisoning Other Countries By Burning Highly-Radioactive Debris

Fukushima will start burning radioactive debris containing up to 100,000 becquerels of radioactive cesium per kilogram. As Mainchi notes:

The state will start building storage facilities for debris generated by the March 2011 tsunami as early as May at two locations in a coastal area of Naraha town, Fukushima Prefecture, Environment Ministry and town officials said Saturday.

***

About 25,000 tons of debris are expected to be brought into the facilities beginning in the summer, according to the officials.

***

If more than 100,000 becquerels of radioactive cesium are found per kilogram of debris, the debris will be transferred to a medium-term storage facility to be built by the state. But if burnable debris contains 100,000 becquerels of radioactive cesium or less, it may be disposed of at a temporary incinerator to be built within the prefecture, according to the officials.

Within the 20-km-radius no-go zone spanning across Naraha and five other municipalities along the coast, debris caused by the magnitude 9.0 quake and the subsequent tsunami has amounted to an estimated 474,000 tons, much of remaining where it is.

How much radiation is that?

It is a lot.

Nuclear expert Arnie Gundersen has said that much lower levels of cesium – 5,000-8,000 bq/kg (20 times lower than what will be allowed to be burned at Fukushima) – would be sent to a special facility in the United States and buried underground for thousands of year. See this and this.

It is comparable to the levels of radioactivity found within the Chernobyl Exclusion Zone. See this and this.

And even the Japanese – who have raised acceptable levels of radiation to absurd levels – would normally demand that material with this radioactivity be encased in cement and buried:

According to plans by the Ministry of Environment, if the radioactive cesium concentration is less than 8,000 Bq/kg, then it is possible to dispose of it by burying it. Rubble that has 8,000 ~ 100,000 Bq must be encased in cement in order to prevent contact with water before being dumped. For rubble that exceeds 100,000 Bq, it must be encased in concrete walls and stored temporarily. The disposal place must be approved of by the Prefectural Governor.

In addition, some allege that debris surpassing 100,000 bq/kg of cesium will be burned, after being mixed with less-radioactive materials.

And many of the incinerators are located smack dab in the middle of crowded cities, and are not equipped to contain radiation.

Intelligence Study Links Low I.Q. To Prejudice, Racism, Conservatism

Wednesday, April 4th, 2012

Are racists dumb? Do conservatives tend to be less intelligent than liberals? A provocative new study from Brock University in Ontario suggests the answer to both questions may be a qualified yes.

The study, published in Psychological Science, showed that people who score low on I.Q. tests in childhood are more likely to develop prejudiced beliefs and socially conservative politics in adulthood.

I.Q., or intelligence quotient, is a score determined by standardized tests, but whether the tests truly reveal intelligence remains a topic of hot debate among psychologists.

Dr. Gordon Hodson, a professor of psychology at the university and the study’s lead author, said the finding represented evidence of a vicious cycle: People of low intelligence gravitate toward socially conservative ideologies, which stress resistance to change and, in turn, prejudice, he told LiveScience.

Why might less intelligent people be drawn to conservative ideologies? Because such ideologies feature “structure and order” that make it easier to comprehend a complicated world, Dodson said. “Unfortunately, many of these features can also contribute to prejudice,” he added.

Dr. Brian Nosek, a University of Virginia psychologist, echoed those sentiments.

“Reality is complicated and messy,” he told The Huffington Post in an email. “Ideologies get rid of the messiness and impose a simpler solution. So, it may not be surprising that people with less cognitive capacity will be attracted to simplifying ideologies.”

But Nosek said less intelligent types might be attracted to liberal “simplifying ideologies” as well as conservative ones.

In any case, the study has taken the Internet by storm, with some outspoken liberals saying that it validates their suspicions about conservatives and conservatives arguing thatthe research has been misinterpreted.

Why the world is running out of helium

Wednesday, April 4th, 2012

– I’ve been following this for years since one of my long-term hobbies has been a deep interest in The Elements of the Periodic Table.    

– The situation with Helium just screams ‘investment opportunity’ to me.   I just wish I has some cash to do something about it.

– Dennis

– – – – – – – – – – – –

A US law means supplies of the gas – a vital component of MRI scanners – are vanishing fast

It is the second-lightest element in the Universe, has the lowest boiling-point of any gas and is commonly used through the world to inflate party balloons. But helium is also a non-renewable resource and the world’s reserves of the precious gas are about to run out, a shortage that is likely to have far-reaching repercussions.

Scientists have warned that the world’s most commonly used inert gas is being depleted at an astonishing rate because of a law passed in the United States in 1996 which has effectively made helium too cheap to recycle.

The law stipulates that the US National Helium Reserve, which is kept in a disused underground gas field near Amarillo, Texas – by far the biggest store of helium in the world – must all be sold off by 2015, irrespective of the market price.

The experts warn that the world could run out of helium within 25 to 30 years, potentially spelling disaster for hospitals, whose MRI scanners are cooled by the gas in liquid form, and anti-terrorist authorities who rely on helium for their radiation monitors, as well as the millions of children who love to watch their helium-filled balloons float into the sky.

Health chief warns: age of safe medicine is ending

Thursday, March 29th, 2012

This story has been building for decades.  From nearly the time when the first antibiotic, penicillin, was put into use.  

– I’ve commented before that I believe one of the answers to the general question:

What is wrong with we Human beings that we are so dysfunctional and self-destructive?

involves an inborn bias.  

– I.e., in acting out our evolutionarily derived nature, we tend to over value things that are concrete, now and near.  

– And, correspondingly, we tend to under value things that are abstract, then and far. 

– Hence, I use the word ‘bias‘ because rationally and logically, all of these things should have equal value.

– That we’d have a bias makes good sense because while we were evolving, in a survival of the fittest world, those of us that tended to favor the concrete, now and near aspects of their environment, probably survived better than those who did not.

– But, this is a new world now and the threats to ourselves and our futures are much more dependent on the abstract, then and far aspects of our world. 

– So, our inborn short-shortsightedness is shown clearly in the problems we’re having now with antibiotics and the growing bacterial resistance to them.  

– Most of us don’t understand why bacterial resistance to antibiotics arises (too abstract).  And when the problem does arise (which it will, whether we understand it or not), it will arise in some future time and place (then and far).  So, all of these factors tend to cause us to devalue the problem’s potential.

– But abstract, then and far as the issue of bacterial antibiotic resistance might have seemed in the past, it is manifesting now and we will unavoidably reap what we’ve sown.

– Personally, I find the idea that we might start dying again from diseases we’d already largely conquered like Tuberculosis, completely repugnant.

The world is entering an era where injuries as common as a child’s scratched knee could kill, where patients entering hospital gamble with their lives and where routine operations such as a hip replacement become too dangerous to carry out, the head of the World Health Organisation (WHO) has warned.

There is a global crisis in antibiotics caused by rapidly evolving resistance among microbes responsible for common infections that threatens to turn them into untreatable diseases, said Margaret Chan, director-general of the WHO.

Addressing a meeting of infectious disease experts in Copenhagen, she said that every antibiotic ever developed was at risk of becoming useless.

“A post-antibiotic era means, in effect, an end to modern medicine as we know it. Things as common as strep throat or a child’s scratched knee could once again kill.”

She continued: “Antimicrobial resistance is on the rise in Europe, and elsewhere in the world. We are losing our first-line antimicrobials.

“Replacement treatments are more costly, more toxic, need much longer durations of treatment, and may require treatment in intensive care units.

“For patients infected with some drug-resistant pathogens, mortality has been shown to increase by around 50 per cent …”

Britain has seen a 30 per cent rise in cases of blood poisoning caused by E. coli bacteria between 2005 and 2009, from 18,000 to more than 25,000 cases.

Those resistant to antibiotics have risen from 1 per cent at the beginning of the century to 10 per cent.

The most powerful antibiotics are carbapenems, which are used as a last line of defence for the treatment of resistant infections.

In 2009, carbapenem-resistant K. pneumoniae, a bug present in the gut, were first detected in Greece but by the following year had spread to Italy, Austria, Cyprus and Hungary.

The European Centre for Disease Control and Prevention reported that the percentage of carbapenem-resistant K. pneumoniae had doubled from 7 per cent to 15 per cent. An estimated 25,000 people die each year in the European Union from antibiotic-resistant bacterial infections.

400 Chernobyls: Solar Flares, Electromagnetic Pulses and Nuclear Armageddon

Sunday, March 25th, 2012

– That’s a pretty over-the-top headline, yes?   I know, but I’ve read this article and several others and I can find nothing speculative or slanted about them.   They are describing simple matters of fact.   We’re not talking about the (as deniers call it) ‘soft’ science of Global Climate Change.

Fact:  There have been more than 100 significant solar Geomagnetic Disturbance (GMD) events in the last 150 years including two; in 1859 (the Carrington Event) and 1921, that, if they occurred today, would cripple our high-tech world severely.

Fact: events like the 1921 event occur regularly every 70 to 100 years and the 1859 about every 500.

Fact: a single nuclear weapon exploded sub-orbitally above the USA could create an ElectroMagnetic Pulse (EMP) capable of bringing down virtually every power grid and piece of electronic equipment within one million square miles or about 50% of the continental USA.

– Governments world wide should be implementing programs (are you listening, New Zealand) to protect against solar GMDs because they will happen and no one know when beyond the statistical statement that bad ones seem to occur every 70 to 100 years.

– And, IMHO, the USA is right to be doing all that it can to prevent Iran and/or North Korea from developing nuclear weapons and military rocket lofting techniques.   All it will take is one mad-man to take out half the USA.  Sorry, but when I listen to Iran’s ranting or look at the face of the new North Korean leader, they both give me the willies.

There are nearly 450 nuclear reactors in the world, with hundreds more being planned or under construction. There are 104 of these reactors in the United States and 195 in Europe. Imagine what havoc it would wreak on our civilization and the planet’s ecosystems if we were to suddenly witness not just one or two nuclear meltdowns, but 400 or more! How likely is it that our world might experience an event that could ultimately cause hundreds of reactors to fail and melt down at approximately the same time? I venture to say that, unless we take significant protective measures, this apocalyptic scenario is not only possible, but probable.

Consider the ongoing problems caused by three reactor core meltdowns, explosions and breached containment vessels at Japan’s Fukushima Daiichi facility and the subsequent health and environmental issues. Consider the millions of innocent victims who have already died or continue to suffer from horrific radiation-related health problems (“Chernobyl AIDS,” epidemic cancers, chronic fatigue, etcetera) resulting from the Chernobyl reactor explosions, fires and fallout. If just two serious nuclear disasters, spaced 25 years apart, could cause such horrendous environmental catastrophes, it is hard to imagine how we could ever hope to recover from hundreds of similar nuclear incidents occurring simultaneously across the planet. Since more than one-third of all Americans live within 50 miles of a nuclear power plant, this is a serious issue that should be given top priority.[1]

In the past 152 years, Earth has been struck by roughly 100 solar storms, causing significant geomagnetic disturbances (GMD), two of which were powerful enough to rank as “extreme GMDs.” If an extreme GMD of such magnitude were to occur today, in all likelihood, it would initiate a chain of events leading to catastrophic failures at the vast majority of our world’s nuclear reactors, similar to but over 100 times worse than, the disasters at both Chernobyl and Fukushima. When massive solar flares launch a huge mass of highly charged plasma (a coronal mass ejection, or CME) directly toward Earth, colliding with our planet’s outer atmosphere and magnetosphere, the result is a significant geomagnetic disturbance.

The last extreme GMD of a magnitude that could collapse much of the US grid was in May of 1921, long before the advent of modern electronics, widespread electric power grids, and nuclear power plants. We are, mostly, blissfully unaware of this threat and unprepared for its consequences. The good news is that relatively affordable equipment and processes could be installed to protect critical components in the electric power grid and its nuclear reactors, thereby averting this “end-of-the-world-as-we-know-it” scenario. The bad news is that even though panels of scientists and engineers have studied the problem, and the bipartisan Congressional electromagnetic pulse (EMP) commission has presented a list of specific recommendations to Congress, our leaders have yet to approve and implement any significant preventative measures.

Most of us believe that an emergency like this could never happen, and that, if it could, our “authorities” would do everything in their power to prevent such an apocalypse. Unfortunately, the opposite is true. “How could this happen?” you might ask.

New process could revolutionize electron microscopy

Wednesday, March 21st, 2012

Researchers at the University of Sheffield have created what sounds impossible – even nonsensical: an experimental electron microscope without lenses that not only works, but is orders of magnitude more powerful than current models. By means of a new form of mathematical analysis, scientists can take the meaningless patterns of dots and circles created by the lens-less microscope and create images that are of high resolution and contrast and, potentially, up to 100 times greater magnification.

In a recent paper published in Nature on March 6, 2012 under the daunting title of “Ptychographic electron microscopy using high-angle dark-field scattering for sub-nanometre resolution imaging,” University of Sheffield scientists M.J. Humphry, B. Kraus, A.C. Hurst, A.M. Maiden and principal investigator John M. Rodenburg outlined their achievements in overcoming some of the limitations that have held back the potential of the electron microscope since its invention by Max Knoll and Ernst Ruska in 1931.

They demonstrated that the way to improve the electron microscope was by removing the thing that is at the very heart of the device – the lens. The difficulty in creating an electromagnetic lens of sufficient quality to allow the electron microscope to work close to its theoretical limits have kept it operating at magnifications 100 times less than what it could be. They found that the way to improve the electron microscope was to eliminate the lens and replace it with a virtual lens, created by applying a new form of mathematical algorithm to diffraction patterns.

Wave Glider aquatic robots set world record

Sunday, March 18th, 2012

Prediction time.  Drug runners and others are going to begin to use these for smuggling.   A small bit of extra technology can make these units able to receive instructions via satellite Internet.  They can be programmed to put their antennas up at night and down in the daytime and with the right coloration and low profile, they will be able to travel unseen from virtually any coast in the world to any other coast.

– Given the huge profit margins involved in smuggling, if they loose a few along the way, it’ll just be the cost of doing business.

– In fact, a secondary industry might spring up among people who want to find them before they deliver their goods to the smugglers.

A group of four autonomous underwater vehicles have just set a world distance record, by traveling from San Francisco to Hawaii

On November 17th of last year, a group of four wave-powered autonomous aquatic robots set out from San Francisco, embarking on a planned 37,000-mile (60,000-km) trip across the Pacific ocean. Recently, the fleet of Wave Gliders completed the first leg of their journey, arriving at Hawaii’s Big Island after traveling over 3,200 nautical miles (5,926 km). By doing so, they have set a new distance record for unmanned wave-powered vehicles – that record previously sat at 2,500 nautical miles (4,630 km).

The Wave Gliders are made by California- and Hawaii-based Liquid Robotics, and each consist of a floating “boat” tethered to an underwater winged platform. The motion of the waves causes these wings to paddle the boat forward, while solar cells on the deck of the boat provide power to its sensors and transmitters. These sensors measure oceanographic data such as salinity, water temperature, wave characteristics, weather conditions, water fluorescence, and dissolved oxygen. GPS and a heading sensor also help the craft to orient themselves.

To the Chinese and the Indians go … the spoils of war

Sunday, March 18th, 2012

– Ah, where did all those billions spent on Afghanistan go and what were they for?   So the Chinese and others could come in and reap the mineral wealth of the country and the Afghan women could be returned to the Taliban for another round of fundamentalist abuse.   Beautiful work USA.

The money and blood pit that is Afghanistan – where the United States and Britain have spent more than 2100 lives and £302 billion ($580 billion) – is about to pay a dividend.

But it won’t be going to the countries which have made this considerable sacrifice. The contracts to open up Afghanistan’s mineral and fossil-fuel wealth, and to build the railways that will transport it out of the country, are being won or pursued by China, India, Iran, and Russia.

The potentially lucrative task of exploiting Afghanistan’s immense mineral wealth – estimated to be worth around £2 trillion, according to the Kabul Government – is only in the early stages. But already China and India in particular are doing deals and beginning work.

Facilities already established are being protected by local army and police, part of whose funding, and most of whose training, has been a US/British responsibility.
