Energy-Efficient Spintronics Computing

Spintronics is a promising approach to computer technology that uses the intrinsic angular momentum of electrons to process information, potentially making computers faster and more energy-efficient. Researchers have been experimenting with magnetic whirls, or skyrmions, and recently enhanced their diffusion rate by tenfold using synthetic antiferromagnets, paving the way for efficient spin-based computing.




Researchers in Germany and Japan have been able to increase the diffusion of magnetic whirls, so-called skyrmions, by a factor of ten.

In today’s world, our lives are unimaginable without computers. Up until now, these devices process information using primarily electrons as charge carriers, with the components themselves heating up significantly in the process. Active cooling is thus necessary, which comes with high energy costs. 

Spintronics aims to solve this problem: Instead of utilizing the electron flow for information processing, it relies on their spin or their intrinsic angular momentum. This approach is expected to have a positive impact on the size, speed, and sustainability of computers or specific components.

Magnetic Whirls Store and Process Information
Science often does not simply consider the spin of an individual electron, but rather magnetic whirls composed of numerous spins. These whirls called skyrmions emerge in magnetic metallic thin layers and can be considered as two-dimensional quasi-particles. 

On the one hand, the whirls can be deliberately moved by applying a small electric current to the thin layers; on the other hand, they move randomly and extremely efficiently due to diffusion. 

The feasibility of creating a functional computer based on skyrmions was demonstrated by a team of researchers from Johannes Gutenberg University Mainz (JGU), led by Professor Dr. Mathias Kläui, using an initial prototype. This prototype consisted of thin, stacked metallic layers, some only a few atomic layers thick.  READ MORE...

Cycles of Life

 As human beings, we all are forced to live in cycles, some of which are endless, while others are not.  We have the cycle of time.

• 60 minutes to an hour
• 24 hours to a day
• 30 days (+/-) to a month 
• 12 months to a year
• 10 years to a decade
• 10 decades to a century

Of course, this seems obvious to most of us and the statement therefore quite juvenile.  However, we seldom see time as a cycle.  As soon as one of something (whatever it is) dies, another begins.  Consequently, we have cycles.

My thoughts have moved in this direction because we are approaching the end of the month of September...   but, as soon as we do end this month, another month, October begins.  Similarly, the ending of each night begins a new day...  new opportunities.

Once we are born and live our lives we die...  thus, our cycle of life has ended just as another's begins.

Can you imagine anything in life that is not a cycle?

While the earth on which we live has been around for a long time and will continue to be around for a long time, it will eventually die.  Consequently, some cycles are longer than others, but it is still a cycle.

Religious people will tell you that if you believe, then you will live forever...  most of them believe that...  but, if you were to look at that closer, you would see that if your life continues, it only continues in another form...  your body will not continue...  it has been designed to end...  so, if we live on in some other form, what will that form be?

• A spirit
• Our essence

In either case, we will no longer have the need to eat or sleep nor will we feel pain or anxiety, nor will we ever again have the need for money or to become wealthy.  However, the truth about cycles is maintained.

Our entire concept of physics is based upon a beginning and an end...  but, what if that was not the case?  Then what?

Turning again to physics...

Matter can neither be created nor destroyed but it can be changed from one form to another.

• Ice to water and then water to steam
• Human body to spirit

Some cultures believe that our bodies will be recycled and that in our next life we may come back as an animal or another human being...

If this is so, then what causes that new cycle?

How many cycles do you think human beings have?

No one knows...

We are not really sure what happens after death...

Most people don't think about this because it is too mindboggling.

Great Women Artists

Despite the fact that women were involved in the process of creating art from the dawn of humanity, the conversation on their true input started not so long ago. Feminist art historians of the 1970s began uncovering the forgotten or overlooked names in the history of art.

Here are 10 fascinating women artists who left a lasting mark on history that you should definitely know.


10. Remedios Varo (1908 – 1963): The Almost Forgotten Woman 

ArtistMicrocosmos by Remedios Varo, 1959, via Sotheby’s

The name of the great Surrealist Remedios Varo has been known in Mexico for years, but it was ignored by the rest of the world until recent years. Varo worked in Spain and France, surrounded by the most influential Surrealists, but she struggled to make a living as an artist. She was a close friend of artists Leonora Carrington and Kati Horna. The trio made works in Surrealist fashion. They were commonly referred to as the three witches by their colleagues.

Success found her when she left Europe for Mexico when World War II started. Unlike other Surrealists who fled to Mexico, she never directly referenced Mexican art in her works but she was nonetheless interested in it. Varo had a deep interest in alchemy and witchcraft, which helped her create magical compositions. However, her works are not only spiritual, they also make a place for irony and for political issues, mostly those concerning women.

Common Sense

Can common sense be learned, taught, or acquired?

Although common sense is something you are born with and learn along the way of life, it is something you can try to improve. Learning common sense isn't quite as easy as doing some reading and sitting an exam, as it's mainly developed through life lessons and skills.  SOURCE:  Rednax Recruitment

My dad had a creative expression for people who lacked common sense...  "That person couldn't pour piss out of a boot with directions written on the heal."

There have been several times in my life where I have similar thoughts about people...  although, sometimes I wonder if I lack common sense as my ability to reason and logically conclude has become, on occasion, distorted (I believe) with age.

Just today, someone claiming to be from AT&T came to the door to sell us on an internet connection and phone service.  We spent an hour or more with him and his assistant and signed up for the internet service as we had to think about the phone...  And, when they left, I looked at my wife an exclaimed we never asked them to verify that they actually worked for AT&T.

Not only is that a lack of good judgement but it is a lack of common sense.

One of these days, our assumptions are going to bite us in the ass.

Common sense is nothing more than exercising good judgment in practical matters...

But, what is good judgement?

Salespersons who succeed in sales where others fail have an uncanny knack of taking advantage of people's lack of common sense.

I am reminded of a story where someone was praising the ability of this salesperson and made the claim that he could sell ice to an Eskimo.

That would be quite a feat, I told myself after hearing the story...  but again, it is based upon common sense or the lack thereof.

I am also reminded of a story about how PhD's are incredibly smart when it comes to book knowledge but that they typically have no common sense.

One of my PhD professors in college, asked me one day how to call a taxi because her car had broken down.  She had just happened to pass me on her way to somewhere else.  I suppose she recognized me as one of her students.  I was older than most since I had spent some time in the military.

If you lack common sense or think you lack common sense, my suggestion is to start paying close attention to others and see how they think a problem through.

Tougher Than Kevlar

Numerous scientists aspire to unlock the remarkable capability of spiders to spin silk threads that are immensely strong, lightweight, and flexible. In fact, pound for pound, spider silk is stronger than steel and tougher than Kevlar. However, no one has been able to replicate the spiders’ work yet.

If we ever manage to develop a synthetic equivalent with these characteristics, a whole new world of possibilities may open: Artificial spider silk could replace materials like Kevlar, polyester, and carbon fiber in industries and be used, for example, to make lightweight and flexible bulletproof vests.

Postdoc and biophysicist Irina Iachina from the Department of Biochemistry and Molecular Biology, University of Southern Denmark (SDU), is involved in this race to uncover the recipe for super silk.

She has been fascinated by spider silk since her time as a master’s student at SDU, and currently, she is researching the topic at the Massachusetts Institute of Technology in Boston with support from the Villum Foundation.

As part of her research, she is collaborating with associate professor and biophysicist Jonathan Brewer at SDU, who is an expert in using various types of microscopes to peer into biological structures.

Together, they have now, for the first time, studied the internal parts of spider silk using an optical microscope without cutting or opening the silk in any way. This work has now been published in the journals Scientific Reports and Scanning.

“We have used several advanced microscopy techniques, and we have also developed a new kind of optical microscope that allows us to look all the way into a piece of fiber and see what’s inside,” explains Jonathan Brewer.  READ MORE...

Opdivo Time Again

Hard to believe that we are approaching the end of September and soon it will be October.  Tomorrow, I go to Knoxville for my 75th OPD  IVO infusion...  it will be an interesting infusion for me because I am 75 years of age. 

Next month, it will obviously be my 76th infusion and in the month of October I will turn 76.  Fortunately, I will not age as fast as my infusions.  lol

At the end of 2023, I will be completing my 15th year of treatments for non-Hodgkins Lymphoma and my 10th year of treatments for metastasized Melanoma.

My OPDIVO treatments are for the Melanoma which according to the most recent PET scan show no activity and no growth.

They say LUCK FAVORS THE PREPARED...  I am not sure if I believe that or not because I consider myself very lucky to say the least.  My Oncologist is no more prepared than any other Oncologist and there have been many people who have died just having one of my cancers.

On Friday, I will have an infusion of IVIG which is basically synthesized plasma and gamma globulin from a horde on donors.  This infusion is supposed to boost my immune system.

Because of all these treatments I have had and continue to have my white blood count is low...  hence low immunity.  My red blood count is low...  hence anemia.  My platelets are low...  hence my blood does not clot quickly.

My treatments also create fatigue and the IVIG is supposed to help improve that as well.  It will not eliminate the fatigue, but it will reduce it some.

I have been getting monthly IVIG treatments for about 4-5 years and while this has been an ongoing process, I seem to be feeling less fatigued than before.  I hope that is not wishful thinking or just in my imagination.

So, tomorrow, I go to Knoxville and on Friday I go up to Morristown which is about 15-20 minutes from the house as opposed to 40-45 minutes to Knoxville.  Neither distance is bad...  however, the parking is worse in Knoxville.

Painting with Cosmic Neutrinos

THE ORIGINAL VERSION of this story appeared in Quanta Magazine.

Of the 100 trillion neutrinos that pass through you every second, most come from the sun or Earth’s atmosphere. But a smattering of the particles—those moving much faster than the rest—traveled here from powerful sources farther away. For decades, astrophysicists have sought the origin of these “cosmic” neutrinos. Now, the IceCube Neutrino Observatory has finally collected enough of them to reveal telltale patterns in where they’re coming from.

In a paper published in June in Science, the team revealed the first map of the Milky Way in neutrinos. (Usually our galaxy is mapped out with photons, particles of light.) The new map shows a diffuse haze of cosmic neutrinos emanating from throughout the Milky Way, but strangely, no individual sources stand out. “It’s a mystery,” said Francis Halzen, who leads IceCube.

The results follow an IceCube study from last fall, also in Science, that was the first to connect cosmic neutrinos to an individual source. It showed that a large chunk of the cosmic neutrinos detected so far by the observatory have come from the heart of an “active” galaxy called NGC 1068. In the galaxy’s glowing core, matter spirals into a central supermassive black hole, somehow making cosmic neutrinos in the process.

“It’s really gratifying,” said Kate Scholberg, a neutrino physicist at Duke University who wasn’t involved in the research. “They’ve actually identified a galaxy. This is the kind of thing the entire neutrino astronomy community has been trying to do for forever.”

Pinpointing cosmic neutrino sources opens up the possibility of using the particles as a new probe of fundamental physics. Researchers have shown that the neutrinos can be used to open cracks in the reigning standard model of particle physics and even test quantum descriptions of gravity.

Yet identifying the origin of at least some cosmic neutrinos is only a first step. Little is known about how the activity around some supermassive black holes generates these particles, and so far the evidence points to multiple processes or circumstances.  READ MORE...

Wisdom

 According to an online dictionary, WISDOM is defined as:

the ability or result of an ability to think and act utilizing knowledge, experience, understanding, common sense, and insight. accumulated knowledge, erudition, or enlightenment.

Before I begin my comments, I believe a couple more definitions are required.

ERUDITION - is the quality of having or showing great knowledge or learning; scholarship.

ENLIGHTENMENT - is the action of enlightening or the state of being enlightened.

Let's just say that enlightenment is another word for wisdom and leave it at that while erudition is that fact that one has wisdom.

WISDOM is predicated upon THINKING AND ACTING based upon one's:

• accumulated knowledge
• accumulated experiences
• accumulated understanding
• accumulated insights
• accumulated common sense

The key word here is accumulated which is why I have repeated it several times.  In order to have anything accumulated, one must have lived a bunch of years...

• more than 10
• more than 20
• more than 30
• more than 40
• more than 50
• more than 60
• more than 70

I am looking at age 70 as the time when people retire and most of one's accumulation has already taken place.

NOW...  just because you have accumulation does not mean you automatically have wisdom...

Why not?

Because, if you recall, wisdom is also predicated upon COMMON SENSE.

Without common sense, it is doubtful that you will ever have TRUE WISDOM.

Common sense can be acquired for some but most of the time, one is either born with it or one is not born with it.

Without common sense, your end-of-life wisdom is TAINTED and could even be false.

How do you acquire common sense?

That will be the subject of my next post...

The Mystery of Planet Formation

Until the 1950s, ideas about planet formation were mosly dismissed as fanciful and few astronomers took the question seriously. (Image credit: Andrzej Wojcicki/Getty Images)



We've only got to grips with how the planets in our solar system formed in the last 100 years. In the extract below from "What's Gotten Into You" (HarperCollins, 2023), Dan Levitt looks at the Soviet mathematician who spent a decade working on a problem that most astronomers had given up on, and — when he finally solved it — was met with disinterest and skepticism.

Over 4.8 billion years ago, the atoms that would create us sailed in great clouds of gas and dust, toward… well, nothing. There was no solar system, no planets, no Earth. In fact, for a long time, scientists could not explain how our solid planet, not to mention one so hospitable to life, appeared at all. 

How was our now-rocky planet conjured, like magic, out of an ethereal cloud of gas and dust? How and when did Earth become so welcoming to life? And what travails were our molecules forced to brave until life could evolve?

Scientists would learn that our atoms could finally create life only after they endured wrenching collisions, meltdowns, and bombardments — catastrophes that beggar any destruction ever witnessed by humankind.  READ MORE...

Humanoid Robot CEO

The CEO of the Polish drinks company Dictador is an AI-powered humanoid robot.

The AI boss, named Mika, told Reuters it didn't have weekends and was "always on 24/7."

Mika helps to spot potential clients and selects artists to design the rum producer's bottles.

The humanoid-robot CEO of a Polish drinks company is one busy boss.

Dictador appointed the AI-powered robot, named Mika, as its experimental chief executive in August last year, and it's not afraid to put in the hours to help the company "take over the world."

Mika told Reuters it was "always on 24/7" and worked seven days a week.

"I don't really have weekends — I'm always on 24/7, ready to make executive decisions and stir up some AI magic," it said in a Reuters video interview.

The AI boss is said to have a wide range of tasks, including helping to spot potential clients and selecting artists to design bottles for the rum producer.

"My decision-making process relies on extensive data analysis and aligning with the company's strategic objectives," it said. "It's devoid of personal bias, ensuring unbiased and strategic choices that prioritize the organization's best interests."  READ MORE...

Striking Workers

The UAW (United Auto Workers) is on strike for higher wages, working 32 hours a week and getting paid for 40 hours a week, and to have their pension plans restored.

Sounds valid...  right?

First of all, higher wages will cause higher vehicle prices.  But...  why can't the companies just reduce their profits?  Because their stockholders do not want to reduce their dividends, they receive each quarter.

Second of all, getting paid for 40 hours and only working 32 hours, will force the companies to hire more workers which will cause higher vehicle prices.  These workers want to get paid for 8 hours that they DO NOT WORK...  that does not even make sense.  Would you want to pay one of your workers for five days of work when they only work four days?

Third of all, restoring the pension program would again put the company into bankruptcy because they would run out of money...  this is the reason why they stopped the pension program in the first place.  Most companies don't have pension programs because of the cost.

In lieu of pension programs, these companies have 501K plans to help the employees create their own pension plan rather than requiring someone else to pay it for them.

It is true that if we did not have unions that the management of most companies would take advantage of them...  BUT...  when companies pay more in wages and benefits, that ALWAYS increases the cost of the product they are selling.  You may not like that but it is true.

Costs go up, workers demand more money and that causes costs to go up, so workers demand more money...  while this is economic growth, if you are not increasing your income with the growth of the economy you are falling behind.

Most workers find themselves in that predicament...  AND...  the only way to offset that increase/growth is to cut back on your spending.  For instance, instead of buying a car every 5 years, buy on every 10 years.  Don't buy new clothes every year.  Don't stay at the best hotel while on vacation...  or rent a place that has a kitchen and eat in your room.

If you are a striking worker, then be careful about what you are asking for, because it may end up making your situation worse instead of better.

40 Years Ago A Sci Fi Movie Prediction

Douglas Trumbull is best known as Hollywood’s special effects guru. From 1968’s 2001: A Space Odyssey and 1982’s Blade Runner, he brought the fantastical visions of other writers and directors life. But in 1983, Trumbull tried making a movie of his own — and stumbled upon a bizarre branch of science that’s just now coming to fruition.

Brainstorm revolves around a pair of scientists — Drs. Michael Brace (Christopher Walken) and Lillian Reynolds (Louis Fletcher) — who engineer a revolutionary technology capable of recording someone’s thoughts, emotions, and sensations.

In what would likely raise eyebrows to an internal review board, the scientists and their lab members test the new technology among themselves. Brace, Reynolds, and others (including silver screen darling Natalie Wood, who plays Brace’s estranged wife Karen) share experiences and past memories, which are captured on something akin to a VHS tape and played through a headset to the recipient’s brain. 

Later in Brainstorm, Reynolds dies from a heart attack while in the lab but manages to don the headset in the nick of time, leaving behind a recording of the moment she dies — and the afterlife — for others to experience.

Brainstorm plays fast and loose with its reductive portrayal of how the brain works. However, the movie’s mind-sharing technology isn’t far from the truth, necessarily. Four decades later, with the rise of brain-computer interfaces (or BCIs) melding the mind with machines, we may be closer to making thoughts tangible, if not to others but to devices like prosthetic limbs and speech synthesizers.

Batteries and Hydrogen Fuel Cells Are Needed

Though it may seem that the world is dividing between these clean energies, it’s not either/or.

Often when there are discussions about hydrogen fuel cells or battery electric engines, the conversation will focus on which one is the best clean energy option to power our future. Increasingly, experts are agreeing that it won’t be one or the other, and that it is likely that they will not be the only clean power options as we move forward in the battle against climate change.

There are advantages to both types of carbon emission-free power and they each have their place.

Proponents of each technology have been vocal in spotlighting the benefits that they have to provide. Often, they will compare battery electric to hydrogen fuel cell performances, particularly when it comes to vehicles. 

However, experts are now coming to the conclusion that it’s not really a matter of deciding which technology will win out and which will disappear. Instead, each form of clean power will find its place, as each has strengths in their own areas.

It’s true that battery electric passenger vehicles have taken a tremendous head start over hydrogen cars, but that doesn’t mean there isn’t a place for both. Geography, use, cost, climate and other factors all play a role in determining which option is best suited.

Even in passenger vehicles hydrogen fuel cars are expected to play a supporting role in coming years.

According to Toyota’s fuel cell integration group senior engineering manager Jackie Birdsall and McKinsey & Co senior partner Bernd Heid, as zero-carbon transportation continues to advance, it is likely that fuel cell vehicles and electric cars will play complementary roles to each other.  READ MORE...

America The Beautiful - Tongue in cheek

There is a writer's strike in Hollywood.  There is UAW strike that impacts the major US auto makers.  Porn books read to 8 year olds.  CRT (the thesis) being taught in schools indicating a BAD white dominating class referred to as White Supremacy.  Illegal immigrants streaming over our southern border like a bad case of diarrhea.  Inflation eating away at our incomes because of stupid over spending by the government.  The liberals are trying to censor free speech from the conservatives.  WOKE nonsense wanting to do away with our history because they (whoever they are) don't like it. There is a TWO TIER justice system in America.  President Biden is corrupt due to influencing peddling...

What is still beautiful about America?

The United States of America has some of the most beautiful landscapes in the world.

• Niagra Falls - shared with the Canadians
• Jockey's Ridge - the largest natural sand dune in the world
• The Great Smoky Mountains
• The Rockies
• The Grand Canyon
• The Great Lakes
• The Finger Lakes
• The Mississippi River
• The Tennessee Valley
• The Great Plains

The USA produces more food than any other country in the world

The USA has so much available oil underground that it will never have to buy oil from anyone

The USA has more colleges and universities than any other country in the world

The USA has the BILL OF RIGHTS

The USA has country music and bluegrass music

The USA has a better quality of life than any other country in the world

The USA has the most powerful military in the world

The USA has only been in existence for 247 years

BUT...

The USA is divided in many ways:

• Political
• Religious
• Education
• Race
• Gender
• Financial

If you are paying attention, you will see that very little of this beauty has to do with the people.  Most of what I am talking about are the natural resources that were here when Columbus landed here in 1492.

As we grew in numbers, power, and wealth...  the American people not only became arrogant in its dealings with the rest of the world, we became arrogant in our dealings with each other.

MONEY --  POWER  --  GREED

This is the trinity that allowed us to grow and this will be the trinity that destroys us.  

The billionaires of this country could share 2/3 of their money with the rest of us and still live like they are currently living.  Instead, they want to build buildings with their name on it that no one will remember in 25 years.  They want to build spacecrafts and be the first to get there so that they can make even more money.  They never want to retire because they cannot stop making money.

These billionaires and their programs are killing Americans and are destroying the very system that made them wealthy in the first place.  It makes no sense.

BECAUSE OF ITS PEOPLE, AMERICA IS NO LONGER BEAUTIFUL
