Just a Few More Thoughts
Now... while I am not the sharpest knife in the drawer... I am smart enough to realize that this is plain stupid and the people who this hurts the most are the general public who basically live from one paycheck to another...
I also understand that 50% of the American population has the relentless desire to go GREEN and while that is a noble quest, it would seem more reasonable to me to go GREEN gradually rather than all at once.
- I think smoking should stop all at once
- I think wars should stop all at once
- I think child abuse should stop all at once
- I think racism should stop all at once
But, I think our energy consumption should stop gradually... but it should stop.
And, I am all for going green and buying an electric car to stop my dependence on fossil fuels.
An electric car has a price tag of anywhere from $60,000 to $80,000 and higher... the distance that an electric car can travel on a charge averages around 400 miles... but, the recharging time is HIGH...

Hybrid Atomic Quantum Computers
But to make a quantum computer out of neutral atom qubits, many individual atoms must be trapped in place by many laser beams. So far, these arrays have only been constructed from atoms of a single element, out of concern that making an array out of two elements would be prohibitively complex.
But for the first time, University of Chicago researchers have created a hybrid array of neutral atoms from two different elements, significantly broadening the system's potential applications in quantum technology. The results were funded in part by the NSF Quantum Leap Challenge Institute Hybrid Quantum Architectures and Networks (HQAN), and published in Physical Review X.
"There have been many examples of quantum technology that have taken a hybrid approach," said Hannes Bernien, lead researcher of the project and assistant professor in University of Chicago's Pritzker School of Molecular Engineering. "But they have not been developed yet for these neutral atom platforms. We are very excited to see that our results have triggered a very positive response from the community, and that new protocols using our hybrid techniques are being developed."
Double the potential
While manmade qubits such as superconducting circuits require quality control to stay perfectly consistent, neutral atoms made from a single element all have exactly the same properties, making them ideal, consistent candidates for qubits.
But since every atom in the array has the same properties, it's extremely difficult to measure a single atom without disturbing its neighbors—they're all on the same frequency, so to speak. READ MORE...
Stopping Constant Complaints
You think you’re doing your best to get everything done to your partner’s satisfaction, whether it’s managing the finances or preparing a 5-star dinner. Much to your dismay, though, your partner continues to find reasons to complain. Maybe you forgot to run the dryer and now have nothing but drenched towels when it’s time for your partner’s shower.
As you think about these situations, it might strike you that some complaints can be reasonable and others can be totally out of line. Everyone forgets things from time to time, and most people get over their annoyance at these minor missteps. Your partner, though, isn’t particularly accepting and, if anything, seems to find something to complain about even when everything is going fine.
Based on new research in the workplace on abusive supervision by Wilfred Laurier University’s Lindie Liang and colleagues (2022), it may be possible to view the constant litany of complaints that your partner engages in as comparable to an overly demanding boss. Although workplace dynamics aren’t exactly the same as those that take place in a romantic relationship, there are still lessons from this research that you can apply to your relationship.
What Effects Can Constant Complaints Have on You?
The Canadian research team’s focus on abusive supervision provides some guidance into understanding the reactions that people have to being the target of someone else’s constant criticism. Fundamental to their analysis is the idea of “interpersonal justice,” a term defined in the literature as your “need to believe that we live in a ‘just world’ where one gets what one deserves and, in turn, deserves what one gets.” Adding to your sense of justice is the idea of “equity,” meaning that you believe what you put into a relationship is equal to the other person’s contributions.
Viewed from this perspective, if you believe that you’re doing your level best to give as much to your relationship as does your partner, your partner’s complaints will feel not only hurtful, but unfair. Unstated, but also expected as part of equity, is the idea that you will be treated with “politeness, dignity, and respect.”
Culture 40,000 Years Old
The migration of homo sapiens from Africa to the rest of the globe is an enduring point of fascination for archaeologists, who have been piecing together human movements across history since the dawn of the discipline. A new study published in Nature last week has helped unlock another piece of the puzzle.
That study, conducted by a research team led by Fa-Gang Wang, is an examination of Xiamabei, a 40,000-year-old archaeological site in northern China. At this site, researchers discovered evidence of a culture that processed ochre, which is used to make pigments. The discovery may seem like a small one, but it led the researchers to rethink how modern humanity evolved.
Ochre is a pigment found in clay, and its presence at archaeological sites suggests the people who lived in Xiamabei had advanced cognitive skills, partly because its points to creativity. However, the pigment can also be used to more practical ends, such as tanning hides.
At Xiamabei, researchers discovered that the humans at the site brought different deposits of ochre there and processed it through pounding and abrasion. This resulted pigments of varying color and consistency. Evidence of the pounding was found on a limestone slab where this processing took place. These humans produced such large quantities of ochre that the slab was stained with pigment.
The unique nature of the tools and processing method found at Xiamabei suggest that instead of one continuous wave of migration across Asia, colonization of this territory happened in distinct phases, the researchers said. “Our findings show that current evolutionary scenarios are too simple,” Michael Petraglia of the Max Planck Institute said in an interview with Science Daily. “Modern humans, and our culture, emerged through repeated but differing episodes of genetic and social exchanges over large geographic areas, rather than as a single, rapid dispersal wave across Asia.”
Another clue as to this disjointedness is what the researchers didn’t find: formal bone tools and ornaments, which were available at the time, but which evidently were not used by some of Xiamabei’s oldest inhabitants.

From the Back Porch
East Tennessee, as I have mentioned before and in my opinion, is a great place to live for a variety of reasons?
- less traffic
- less polution
- less crime
- less wokeness
- less expensive
- more reacreational lakes
- close to airport
- close to Smoky Mtns
- lots of farmland
- excellent healthcare
- calming lifestyle
In my backyard, I can watch squirrels and rabbits play and interreact with their environment. Across the street from the front porch is an open field where families of deer roam free and easy without the fear of being hunted. On either side of the house, I see birds of all sorts such as:
- Cardinals
- Blue birds
- Blue jays
- Doves
- Black birds
- Crows
- Purple martins
- Hawk
- Woodpeckers
- Robins
- Finches
Coming from the Piedmont of North Carolina, I can honestly say that I prefer East Tennessee after living here for over 30 years.
On Being White
Born with a Scorpion horoscope, I found myself the most happy when I am alone in the desert, living a life of isolation and self-reflection.
Let's be clear...
I was born CAUCASIAN... 82 years after the Civil War and the conclusion of slavery in the United States; therefore, I am not a part of slavery nor will I ever be a part of slavery and resent people telling me that because I am white, I am associated with slavery...
If you think I am a racist, then the fact that you think that about me, MAKES YOU A RACIST... I am an American just as you are an American... and, trying to identify or classify us in any other way, is not only misleading but ignorant because you are allowing the past influencing your future rather than using the past to make your future better.
MLK Jr. said that we should judge people by their actions not by their color...
Explain to me what is incorrect about that statement...
As a WHITE MAN living in the USA, I live my life as I want it to be lived, not as how you want me to live my life. As a RETIRED WHITE MAN, I see us all as one group of people, some of which are good and some of which are bad... Some of us live in the city, some of us live in the country, and some of us live in the suburbs. Some of us live on the east coast or west coast, some of us live in the middle while some of us live in the north or south.
We have educated and non educated Americans, religious Americans, and non-religious Americans. We have tall Americans, short Americans, fat Americans, and thin Americans, but we are all Americans.
- I had no choice about my birth
- I have no choice about my parents
- I had no choice about my birth country or state
- I had no choice about my birth body
- I had no choice about my birth mentality
- I had no choice about my birth personality
I suggest you think about this the next time you try and judge me...
Math and Machine Learning
Machine learning makes it possible to generate more data than mathematician can in a lifetime
For the first time, mathematicians have partnered with artificial intelligence to suggest and prove new mathematical theorems. While computers have long been used to generate data for mathematicians, the task of identifying interesting patterns has relied mainly on the intuition of the mathematicians themselves. However, it’s now possible to generate more data than any mathematician can reasonably expect to study in a lifetime. Which is where machine learning comes in.
Two separate groups of mathematicians worked alongside DeepMind, a branch of Alphabet, Google’s parent company, dedicated to the development of advanced artificial intelligence systems. András Juhász and Marc Lackenby of the University of Oxford taught DeepMind’s machine learning models to look for patterns in geometric objects called knots. The models detected connections that Juhász and Lackenby elaborated to bridge two areas of knot theory that mathematicians had long speculated should be related. In separate work, Williamson used machine learning to refine an old conjecture that connects graphs and polynomials.

“The most amazing thing about this work and it really is a big breakthrough is the fact that all the pieces came together and that these people worked as a team,” said Radmila Sazdanovic of North Carolina State University.
Some observers, however, view the collaboration as less of a sea change in the way mathematical research is conducted. While the computers pointed the mathematicians toward a range of possible relationships, the mathematicians themselves needed to identify the ones worth exploring.
A Spectacular Universe
Just 12 million light-years away, the galaxies Messier 81 and 82 offer a nearby preview of the Milky Way-Andromeda merger.
Right in our cosmic backyard, a preview of the Milky Way’s future unfolds.
The galaxy Messier 81, also known as Bode’s Galaxy, is one of the brightest and closest galaxies to Earth not found in our Local Group. By connectng the lower-left corner of the Big Dipper’s cup to the upper-right corner and then traveling that same distance in the same direction, you can find M81 and the other major galaxies of its group all clustered together.

Just outside the Big Dipper’s “cup,” Bode’s Galaxy, Messier 81, lingers.
This optical image of Bode’s Galaxy, M81, comes courtesy of the Hubble Space Telescope. The spiral arms are littered with hot, young, blue stars, while large extent of the arms indicates a gravitational interaction with one or more nearby neighbors. A wider-field and multiwavelength view supports that. (Credit: NASA, ESA and the Hubble Heritage Team (STScI/AURA))
12 million light-years away, it’s a naked eye object for those with acute vision and exceptionally dark skies.
The two largest, brightest galaxies in the M81 Group, M81 (right) and M82 (left), are shown in the same frame in these 2013 and 2014 photos. In 2014, M82 experienced a supernova, visible in the 2014 (blue) image just above the galactic center. (Credit: Simon in the Lakes)
The largest galaxy in the M81 group moves ever-so-slightly towards us. READ MORE...
Magnetic Fluid Engines
China is reportedly developing and testing its hypersonic technology at an unprecedented pace. It claims to have added another engine to its arsenal that can propel it to the forefront of the hypersonic race.
China’s hypersonic weapons program hopes to springboard itself into the future with an “air-breathing” magnetic fluid engine that might make it commercially possible to go anywhere on Earth in under an hour.
By 2035, China intends to construct a hypersonic passenger fleet that will use near-Earth orbit to go to any destination in the world in under an hour. Even though this program has been ridiculed by Western observers, China remains committed to developing an aircraft of this caliber and expanding the fleet in over a decade after a successful operation.
The program’s lead scientist claimed that the super-quiet engine with no moving parts will also aid in the construction of the next-generation launch vehicle, which is expected to enhance China’s space capability tremendously.
The ‘Next Generation Launch Vehicle’ is likely to launch a crewed mission to space and could potentially make its first flight in 2026. An advanced engine powering it could turn out to be a technological space milestone for the communist nation. READ MORE...
