Topics: Modern Physics, Nanotechnology, Quantum Mechanics, Superconductors

A theory that describes how quantum particles interact with each other in 1D has been put to the test by two independent teams of physicists. In one experiment, aspects of the Tomonaga–Luttinger theory were verified using laser-trapped ultracold atoms. The other study made use of superconducting devices. Confirmation of the theory could lead to the development of new technologies based on nanowires and other 1D systems. Applications include electronics, sensing, energy harvesting and quantum information.

Tomonaga–Luttinger theory describes a 1D ensemble of interacting quantum particles in terms of a Tomonaga–Luttinger liquid (TLL). It predicts properties of 1D quantum systems such as how electrons behave in a nanowire. Testing these predictions in a systematic way has not been possible, however, because it is very difficult to control how particles interact in 1D systems such as nanowires.

Mori's family adventure Kick-starter

https://www.kickstarter.com/projects/2140728215/moris-family-adventures-kids-international-travel/descriptionMori’s Family Adventures is a family traveling book narrated by my son Mori. The series follows my family as we travel the world, enjoying family fun, and learning a thing or two about the regional cultures.Our goal is to get this book series in front of early grade school students who are just starting to read on their own. We feel that students this age have little to no cultural experiences do to the great cost of traveling abroad. Also the narrow educational direction we commonly see. Mori’s Family Adventures provides children and their teachers a median to show other cultures in an immersive way. The educational goal of the series is to expose different cultures to kids. Show the fun family activities their family can have at these locations. Lastly, to teach some historical information about the region, and get children excited about seeing new things outside of the U.S.https://youtu.be/aGV7QoUXHS0

Oligarchy...

Image Source: Foundations of Government, Slide Player, Slide 5

Topics: Commentary, Existentialism, History, Politics

I let the previous post last Friday stand without any other comment. I'm also working on reports for three projects in graduate school. I have a limited amount of hope that things will change. It is partly the subject of today's commentary.

I read "Letters at 3 AM: 'O' is for Oligarchy" in the print version of The Austin Chronicle when I lived in Austin, Texas. As in the date in the online version, I remember reading it in 2010. The premises it raised have aged very well, unfortunately.

*****

The US is dominated by a rich and powerful elite.

So concludes a recent study by Princeton University Prof Martin Gilens and Northwestern University Prof Benjamin I Page.

This is not news, you say.

Perhaps, but the two professors have conducted exhaustive research to try to present data-driven support for this conclusion. Here's how they explain it:

Multivariate analysis indicates that economic elites and organised groups representing business interests have substantial independent impacts on US government policy, while average citizens and mass-based interest groups have little or no independent influence.

In English: the wealthy few move policy, while the average American has little power. Source: BBC News, Study: US is an oligarchy, not a democracy, 17 April 2014

*****

The U.S. government does not represent the interests of the majority of the country's citizens, but is instead ruled by those of the rich and powerful, a new study from Princeton and Northwestern universities has concluded.

The report, "Testing Theories of American Politics: Elites, Interest Groups, and Average Citizens" (PDF), used extensive policy data collected between 1981 and 2002 to empirically determine the state of the U.S. political system.

After sifting through nearly 1,800 U.S. policies enacted in that period and comparing them to the expressed preferences of average Americans (50th percentile of income), affluent Americans (90th percentile), and large special interests groups, researchers concluded that the U.S. is dominated by its economic elite.

Ganesh Sitaraman carried on this traditional observation of the obvious in The Guardian:

While the ruling class must remain united for an oligarchy to remain in power, the people must also be divided so they cannot overthrow their oppressors. Oligarchs in ancient Greece thus used a combination of coercion and co-optation to keep democracy at bay. They gave rewards to informants and found pliable citizens to take positions in the government.

These collaborators legitimized the regime and gave oligarchs beachheads into the people. In addition, oligarchs controlled public spaces and livelihoods to prevent the people from organizing. They would expel people from town squares: a diffuse population in the countryside would be unable to protest and overthrow government as effectively as a concentrated group in the city.

They also tried to keep ordinary people dependent on individual oligarchs for their economic survival, similar to how mob bosses in the movies have paternalistic relationships in their neighborhoods. Reading Simonton’s account, it is hard not to think about how the fragmentation of our media platforms is a modern instantiation of dividing the public sphere, or how employees and workers are sometimes chilled from speaking out.

Greece, the birthplace of our ideas on democracy as Rome was our ideals of a republic is an apropos historic comparison.

In my March 31 post, The Shattering, oligarchy wasn't mentioned, but implied. I observe the former head of the KGB, he and the other former members of the Politburo have abandoned the ideals of the Communist Manifesto. They don't appear at all interested in "sharing their wealth," but in its avaricious accumulation.

Perhaps their American counterparts have left the "quaint" notion of a federal republic.

Ventrella Quest Cartoon - Free Speech

"We have 'given them the store' of white supremacist bigotry, and our republic. I'm concerned apathy, racism, stupidity and tribalism may well not allow us... to get it back." The Shattering, March 31, 2017

“The really dangerous American fascist... is the man who wants to do in the United States in an American way what Hitler did in Germany in a Prussian way. The American fascist would prefer not to use violence. His method is to poison the channels of public information. With a fascist the problem is never how best to present the truth to the public but how best to use the news to deceive the public into giving the fascist and his group more money or more power... They claim to be super-patriots, but they would destroy every liberty guaranteed by the Constitution. They demand free enterprise, but are the spokesmen for monopoly and vested interest. Their final objective, toward which all their deceit is directed, is to capture political power so that, using the power of the state and the power of the market simultaneously, they may keep the common man in eternal subjection."

Check out my latest book: Justine Mingana!

The peaceful occupation of Earth by the benevolent Calaar opened avenues of opportunity for Justine Mingana and hundreds of millions of other humans trapped in poverty. Mingana achieved what she never thought possible as a child: she became a starship captain. Another alien race arrived in Earth's skies, this one hostile and aggressive, offering a brutal contrast to Calaar altruism. Now, Mingana must make a show of loyalty to a new set of occupiers while pursuing a hidden agenda, one that may lead to the demise of her ship and crew. For the sake of Earth's liberation from the clutches of tyrants, Alien and human alike, Mingana is prepared to make that sacrifice...and she is just as prepared to kill.

future dwelling technology

OK, my latest thinking. The quonset has dormers on each side which is connected to stacked shipping containers. The sea-cons can be porches or room expansion. The quonset ends are flat so you can attach dome-like extensions. I used an octagonal shaped dome in keeping with standard 90 degree building technology. And yes, you don't have to use shipping containers, but they are ready-made steel frames. And you could just as well dock your tiny house on the side of the quonset.

Someone asked me what kind of people would live in my dwellings. I am a bungalow person, smallish but bigger than a tiny house. How to live in a smallish house is living in your mind instead of living by your body. The body requires space and stuff, both of which can be costly. But you can do whatever you imagine, so make choices. Yoda could live with the Hulk (they both are green and powerful) but the Hulk (a big guy) changes into human (a tech stuff buff) who requires lots of space and Yoda ("mind" you) requires less space. If you figured it out, I'm am hooked on what can be built from available stuff today because even if you become super-human, housing design moves like a glacier. I'm just breaking the ice (for tea). You must enlist your powers and "built to suit."

Polite Society...

Image Source: Cap Times, Amy Goodman, Dennis Moynihan related article

Topics: Commentary, Politics, Research

"An armed society is a polite society. Manners are good when one may have to back up his acts with his life." Robert A. Heinlein

"The only thing that stops a bad guy with a gun is a good guy with a gun." NRA Executive Vice President Wayne LaPierre

On the night of October 1, 2017, a gunman opened fire on a large crowd of concertgoers at the Route 91 Harvest music festival on the Las Vegas Strip in the State of Nevada, leaving 58 people dead and 489 injured. Between 10:05 and 10:15 p.m. PDT, 64-year-old Stephen Paddock of Mesquite, Nevada, fired hundreds of rifle rounds from his suite on the 32nd floor of the nearby Mandalay Bay hotel. About an hour after Paddock fired his last shot, he was found dead in his room from a self-inflicted gunshot wound. His motive is unknown.

The incident is the deadliest mass shooting committed by an individual in the United States. The crime reignited the debate about gun laws in the U.S., with attention focused on bump firing, a technique Paddock used to allow his semi-automatic rifles to fire at a rate similar to that of a fully automatic weapon. Source: Wikipedia

  • The claim that gun ownership stops crime is common in the U.S., and that belief drives laws that make it easy to own and keep firearms.
  • But about 30 careful studies show more guns are linked to more crimes: murders, rapes, and others. Far less research shows that guns help.
  • Interviews with people in heavily gun-owning towns show they are not as wedded to the crime defense idea as the gun lobby claims.

Guns took more than 36,000 U.S. lives in 2015, and this and other alarming statistics have led many to ask whether our nation would be better off with firearms in fewer hands. Yet gun advocates argue exactly the opposite: that murders, crimes and mass shootings happen because there aren't enough guns in enough places. Arming more people will make our country safer and more peaceful, they say, because criminals won't cause trouble if they know they are surrounded by gun-toting good guys.

Is there truth to this claim? An ideal experiment would be an interventional study in which scientists would track what happened for several years after guns were given to gun-free communities and everything else was kept the same. But alas, there are no gun-free U.S. communities, and the ethics of doing such a study are dubious. So instead scientists compare what happens to gun-toting people, in gun-dense regions, with what happens to people and places with few firearms. They also study whether crime victims are more or less likely to own guns than others, and they track what transpires when laws make it easier for people to carry guns or use them for self-defense.

Most of this research—and there have been several dozen peer-reviewed studies—punctures the idea that guns stop violence. In a 2015 study using data from the FBI and the Centers for Disease Control and Prevention, for example, researchers at Boston Children's Hospital and Harvard University reported that firearm assaults were 6.8 times more common in the states with the most guns versus those with the least. Also in 2015 a combined analysis of 15 different studies found that people who had access to firearms at home were nearly twice as likely to be murdered as people who did not.

This evidence has been slow to accumulate because of restrictions placed by Congress on one of the country's biggest injury research funders, the CDC. Since the mid-1990s the agency has been effectively blocked from supporting gun violence research. And the NRA and many gun owners have emphasized a small handful of studies that point the other way.

Carbon Nanotube FET...

Figure 1. A three-dimensional integrated circuit, made possible with carbon nanotubes (CNTs). The circuit senses and classifies ambient gases using a multilayered stack of devices that are connected by platinum wires known as interlayer vias. In the top layer, roughly 1 million CNT field-effect transistors (FETs) register a change in electrical resistance when the gas molecules adsorb on a CNT. The second layer hosts memory cells that read and store the signals created by the FETs just above them. The third layer contains another million FETs that process the sensor data and implement a machine-learning algorithm to identify the type of gas picked up. Conventional silicon CMOS circuitry on the bottom acts as an interface to external devices. (Adapted from ref. 2.)

Topics: Carbon Nanotubes, Computer Engineering, Nanotechnology, Quantum Mechanics

In 2013 graduate student Max Shulaker, his adviser Subhasish Mitra, Philip Wong, and their Stanford University colleagues built the first computer made entirely of carbon nanotube (CNT) field-effect transistors (FETs). 1 The achievement was eagerly anticipated. Even before their first incorporation into FETs in 1998, CNTs had been touted as a superior substitute for the silicon channel that shuttles current between the traditional FET’s source and drain electrodes.

The intrinsic thinness of single-wall CNTs—essentially graphene sheets rolled into hollow cylinders a nanometer wide—enables superb control over power dissipation in the transistor’s off state and allows the transistor to switch off and on with much lower energy consumption than is possible with any other material. Moreover, thanks to that one-dimensionality, which suppresses scattering, charge carriers in CNTs have a much higher velocity for a given electric field than in Si. (See the article by Phaedon Avouris, Physics Today, January 2009, page 34.)

The 2013 computer was modest: It contained fewer than 200 FETs, ran at a clock speed of just 1 kHz, and implemented a single instruction. Nonetheless, the instruction was a conditional statement that qualified the computer as “Turing complete,” able to make any calculation given enough memory and time. The achievement also reassured Shulaker, now a professor at MIT, and his Stanford colleagues that CNTs could form the foundation for a much more complex system.

The researchers have now built a prototype system that embodies a vision of a transformative computer architecture—one in which computing, data storage, and input and output technologies are each fabricated into two-dimensional layers that are built up into a 3D integrated circuit.2 Shown schematically in figure 1, the circuit consists of more than 2 million CNT FETs and more than 1 million memory cells. The components are divided among three layers—stacked on the same chip atop a layer of Si CMOS circuitry and interconnected by a forest of fine platinum wires.

The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 2017 was awarded to Richard H. Thaler "for his contributions to behavioural economics".

Integrating economics with psychology
Richard H. Thaler has incorporated psychologically realistic assumptions into analyses of economic decision-making. By exploring the consequences of limited rationality, social preferences, and lack of self-control, he has shown how these human traits systematically affect individual decisions as well as market outcomes.

Our Dreams are not Big Enough

It was a sunny hot day. It was an Alabama sunny hot day in August. I sat in the parking lot of the U.S. Space and Rocket Center debating to myself whether I should go thru with this.

 

After several minutes, I decided that I came this far, I might as well go all the way. So over my shorts and T-shirt, I placed the thin aluminum style suit on. Not much people noticed me. When I was done and zipped the suit up, I became very warm and unusually uncomfortable. I placed the other accessories on like an old Army pistol belt and boots. The suit was made to resemble a Mercury silver spacesuit. There were no african-american astronauts that were part of the Mercury 7 team, but a person can still dream. They fueled the imagination of many Americans regardless of race and gender.

As I proudly walked to the entrance of the Space and Rocket Center, I then noticed the stares. Little children were pointing their finger at me. All I could do was to wave back at them with a nervous grin.

 

About sixty years ago, other men wore similar suits like mine. The only difference is that theirs was the real McCoy and they were the real pioneers of this new frontier of space.

 

It started with a dream from individuals like Copernicus, Katherine Johnson and Werner Von Braun. They  had a dream and their contributions helped us to the land a man on the moon.

 

In pursuing their wildest dreams, there are setbacks and sacrifices. Many lives were lost in the launch pad for both the United States and the former Soviet Union.

 

But the dream didn’t die.

 

They learned from their mistakes and paid homage to those we lost who dared to believe.

 

The dream went on. From it, it launched new innovations and sciences. From it, we built a shuttle and then a space station where human beings has spent over a year in orbit. We have sent probes to Mars and to the very boundaries of our Solar system and beyond.

 

Those were big dreams.

 

As I walked through the rocket center taking video I would use later on, people began to come up to me to shake my hand. Some employees, who never saw me thought I worked there also. Every person I saw greeted me with a smile.

 

Soon my nervousness went away and I did what I determined to do.

 

My goal is nothing to compare with landing on the moon. But it’s still worthwhile. To show those that anyone, I mean anyone, can fly on a rocket or have impossible dreams. It becomes possible when you begin to believe that you can do it.

 

I left with a sense of accomplishment and pride.

 

From the video footage I filmed, I was able to craft a science fiction short film called Opportunity 7.

 

Dare to Dream.
