A team of Swiss scientists has performed a massive test of one of the strangest paradoxes in quantum mechanics, a huge example of the sort of behavior Albert Einstein skeptically called “spooky action at a distance.”

The story begins more than 80 years ago. Way back in 1935, Einstein and physicists Boris Podolsky and Nathan Rosen found something strange. They entangled two particles- let’s call them Alice and Bob — so that their physical properties were linked even across wide distances, and anything you did to one particle would impact the other. Intuitively, you’d think that if you had access to Alice, you’d know way more about her than you would about Bob, who’s a distance away. This is also what you’d expect given Einstein’s relativistic laws of physics at large scales. But the physicist trio discovered something odd, now called the Einstein-Podolsky-Rosen (EPR) paradox: By studying Alice, you actually learn much more about Bob than you do about Alice.

Later experiments using individual particles proved the physicists correct on this point. But this new experiment, published today (April 26) in the journal Science, shows that the effect still occurs using even a clump of nearly 600 supercooled particles.

It isn’t surprising exactly that a paradox originally framed in terms of two particles also occurs for clumps of hundreds of particles. The same physics at work in a very small system should also work in much larger systems. But scientists perform these ever-more-complex tests because they help confirm old theories and narrow down the ways in which those theories might be wrong. And they also demonstrate the capability of modern technology to put into action ideas that Einstein and his colleagues could think about only in abstract terms. To pull off this experiment, the researchers cooled about590 rubidium atoms (give or take 30 atoms) to the bleeding edge of absolute zero.

At that temperature, the atoms formed a state of matter called a Bose-Einstein condensate, which,  as Live Science has previously reported is a state of matter in which a large group of atoms become so entangled that they start to blur and overlap with one another; they begin to behave more like one large particle than lots of separate ones. Quantum physicists love to experiment with Bose-Einstein condensates because this kind of matter tends to demonstrate the weird physics of the quantum world at a large enough scale for the scientists to observe it directly.

In this experiment, they used high-resolution imaging to measure the spins of different chunks within the soup of rubidium atoms. The atoms in the condensate were so entangled that the physicists were able to predict the behavior of the second chunk by studying only the first. Both chunks of atoms, they showed, were so entangled that the behavior of the second chunk was in fact more knowable when only the first was observed, and vice versa.

The EPR paradox had come to life, on a relatively massive scale for the quantum world.

Robotics is the wave of future.

In a world of hi-tech if cyborgs are seriously pursued as higher state of human ingenuity why not teach robots certain human values? It is cost effective that government shall have an excuse to throw tax-payer’s money into something of value.  Would it not be worthwhile if  our expertise with AI can show us how to live with all in harmony?

I merely inverted the normal usage of man to give robots a pride of place. Instead of Cold War we make them initiators of peace so man is spared from the awful truth as the destroyer. It means for us pressing the nuclear button is not an option. May be robots shall do it for us.  Robots are our handiwork so is money, If we can make money our be-all, why not give value we so long attached to our humanity to AI? Such inversion makes us look at ourselves how much we have undervalued our humanity. It has therefore a shock value is it not?

Our curiosity is boundless that however prevents our body to follow since we as human species are to make the earth our home. It speaks of certain intelligence that we can send workable spacecrafts with the intent of colonizing exoplanets. In fact NASA is about to launch the Tessa mission to explore the new planets. Why should we teleport us if we can send our microbiome to do it for us instead?AI has its value so have cyborg programmed in some lab to perform certain tasks where humans may not do. Into a corrosive vat of acid we can send a cyborg and if it be melted we shall not be unduly cut up for the loss; for we can always go back to our drawing board and come up with a better model. Or send a robot into the centre of the earth where it can be our eyes and hands. Man is not intended for such death defying acts but to live and learn of his kind. AI in shorts cleans up the mess we make.

Microbiome is our solution: having found the earth our home not conducive to peace and harmony let them reconstitute it for us. Do we change our prejudices and everything non essential, to create a peaceable coexistence? No. Since what is in our own hand shall not bend to our will why not we resort to alternative: deconstruct man so we send the worlds that have colonized us instead to speak for ourselves? Our microbiome for example is likely candidate. You’re more microbe than human – if you count all the cells in your body, only 43% are human. The rest is our microbiome and includes bacteria, viruses, fungi and single-celled archaea.The human genome – the full set of genetic instructions for a human being – is made up of 20,000 instructions called genes. But add all the genes in our microbiome together and the figure comes out at between two million and 20 million microbial genes.It’s known as the second genome and is linked to diseases including allergy, obesity, inflammatory bowel disease, Parkinson’s, whether cancer drugs work and even depression and autism.

Man is by force of habit no longer a single entity anymore. Us and Them are what man invented with two good eyes his Maker gave him. Man set about himself as homo sapiens  and what did he come up with? Two Tribes. Mankind is deconstructed into many pigeon holes so we shall know how to deal with each when necessary. (‘Just a dog whistle shall do for Jim Crow to feel top of the Ozark mountains. I mean mood wise, while another needs bourbon’.) If man can be divided it means either he belongs to us or them. It is a kind of logic used by fellows who cannot differentiate left from his right foot. So he adds Alt right as though his gut fora is any wiser than mine. Thus we shuffle and deal marked cards and the Haves and Have-nots, carnivores, herbivores, the believers and kaffirs are all cards we carry around.

The second genome is proven more clever than our first. What shall the third wave be, I wonder.

Human cells make up only 43% of the body’s total cell count. The rest are microscopic colonists. It is a microbiome I may disown but to no avail. My affluenza owes to it. Caravans may come from Honduras and their destination is northwards. President Trump is crying foul. He wants the army and the big guns to put an end to their onward march. If these poor huddled masses could raise the temperatures of well heeled Eastern folks even before they had come, what stuff is man made of? Fear is a strong emotion and the very idea  makes the Big Chief and his isolationist cronies cringe;  even their salads wilt in their plates. Tiny yes yet they do have power, you will have to agree.

Man can be broken up and the elements in his body be set into so many heaps. Man reduced to dollars and cents. Actual cost in dollars is what one carries in his shoes lest he should be mugged in some part of the Kinky Town, he needs some pin money, you will have to agree.

Man  as an idea is a parasite within world of ideas and mostly what he seeks is the comfort of well worn cliches and ideas with which he can lord over the dunghill. Darwin’s ideas passed through Herbert Spencer, whose milk and water veins dilated and he said it was ‘survival of the fittest.’ It got the heads of nations thinking. So man must be tinkered with and his eugenics found votaries who burnt incense before their bleached unwashed bodies to sing a paean for their Aryan supremacy. In terms of ideas man is bit of mush, spud and cackle and bubble when they want to go on a rampage in Charlottesville, Virginia. Such mongrel race has nothing worth boasting over their color you will have to agree.

Think of man as fragmented as a crazy quilt stitched by hands suffering from delirium tremens. All that greed shows out of place for the fellows who are stealing, bluffing and cheating all for feeding microbiome that has no appreciation for it in the first place. His labour to cut a figure among such whitewashed walking sepulchers is ridiculous to the extreme, you will have to agree.

Rain in Spain stays on the plain;

What shall we do with California wine?

It is plain, -what a shame
Gone sour in a tariff war.

 

Wine and blood are red:

Madder than hell is wine gone bad

It is plain-what a shame

Gone sour in a tariff war.

 

Luminum shall wilt,

So shall steel melt,

When China say Boo!

Some shall say: ” Cheese!

There is glut in the Market

But bread in the basket

Shall wait for no man-

Pass some butter please!

Stephen Hawking died today (March 14), leaving behind a massive legacy of work as an astrophysicist, science communicator, activist, and figure of pop culture admiration. And on the day of his death, a question he raised and worked on until the last years of his life remains unanswered: Can information really be lost to the universe?

Hawking’s most famous paper, “Black Hole Explosions?,” published 44 years ago in 1974, took a hatchet to the whole notion of black holes as physicists had previous understood them. And it was Hawking’s first whack at that basic question.

“Classically, a black hole should be ‘perfectly cold’ in the sense that it absorbs everything but emits nothing. This is how they were understood in the early 1970s,” Robert McNees, a physicist at Loyola University in Chicago, wrote in an email.

A black hole like that would radiate energy no matter could escape escape from it. It would just… exist, cold, silent, and eternal. Hawking’s paper made the black holes alive ­— and possibly mortal.

“When Stephen considered quantum mechanical effects in the mid-70s, he discovered that black holes should, in principle, radiate as if they were thermal objects with a temperature,” McNees told Live Science. “If they radiate energy then their mass will decrease. And he found that as this happens, as they shrink, their temperature goes up and they radiate even faster.”

Eventually, perhaps, the black hole would disappear entirely, or shrink to a little nubbin. Without fully reconciling relativity and quantum mechanics in a robust theory of “quantum gravity” (what physicists call a “theory of everything”), the final stage of that black hole evaporation remains a mystery.

“The problem is that, according to his calculations, the radiation is perfectly thermal. It doesn’t retain any information about the state of the material that formed the black hole, and this would violate a fundamental rule in quantum mechanics,” McNees wrote.

Quantum physics requires that the whole future and past of every particle should be, in principle, possible to figure out and link through a series of chained, causal, probabilistic events. But if a black hole release an undifferentiated soup of particles with their information — their histories — unrecoverably erased, then that requirement is fundamentally broken.

“[Physicists call this] the ‘black hole information paradox,’ and attempts to resolve it have driven much of the work in quantum gravity since it was first articulated,” McNees wrote.

Hawking was already an accomplished physicist by 1974. And many brief biographies imply that, following the publication of his 1988 popular science book “A Brief History of Time,” his most important scientific work was behind him. But Hawking continued to produce significant and controversial scientific papers until as recently as this decade, wrangling with the paradox he introduced decades earlier.

The most dramatic late-career paper Hawking wrote suggested the black holes as they’ve classically been understood don’t exist at all.

In “Information Preservation and Weather Forecasting for Black Holes,” published in 2014, he suggested that the “event horizon” around black holes, the point beyond which even light could not escape, doesn’t really exist. Instead, he wrote, there’s simply an “apparent” horizon of trapped light, which could fade away and allow the light to escape.

“The absence of event horizons mean that there are no black holes — in the sense of regimes from which light can’t escape to infinity,” Hawking wrote.

He also suggested some fundamental conceptual problems with a number of features physicists had attributed to black holes, like “firewalls” around their boundaries that destroy observers who try to enter.

That wasn’t Hawking’s final word on science. As recently as 2016, Hawking published a paper with the University of Cambridge physicist Malcolm Perry and Harvard University physicist Andrew Strominger called “Soft Hair on Black Holes.”

The research team argued that black holes are surrounded by “soft” or zero-energy particles, which they call hair. That hair, they wrote, stores the lost information of particles emitted by black holes on “holographic plates” beyond the black holes’ boundary regions. So the information, while displaced, is never truly lost.

“A complete description of the holographic plate and resolution of the information paradox remains an open challenge, which we have presented new and concrete tools to address,” they wrote.

Even near the end of his life, Hawking remained very much a working scientist, presenting ideas that advanced his field, and ideas his colleagues rejected.

“It’s my impression that the 2014 paper is not widely accepted. The 2016 paper, on the other hand, which is work with Perry and Strominger, is a direction that people are still actively working on,” McNees wrote.

“The black hole information paradox has been one of the defining questions for people working on quantum gravity. And, as it remains unanswered, I think it remains the most interesting question that [Hawking] raised.” (Ack: LiveScience/ Stephen Hawking Never Answered His ‘Most Interesting’ Scientific Question/Rafi Letzter of March 14,2018)

He was a visionary alright. I am more concerned with the question that remains unanswered:  the Information Paradox which the existence of black holes threw up shall be vigorously followed yet more riddles grist for the mills namely Scientific Inquiry..

Information can never be lost the idea was first proposed by Einstein. We have black holes, white holes, worm holes. These are all highways, back alleys, hyper loops for information to be sent across. Only problem for Science is that they do not know the addressee. May be out there is a Celestial Post office and one sitting there with a seal ready, Address Unknown, Return to Sender.

“It’s strange how you can get booze on credit but not bread.”This quote is from Pandora’s Box(1929), which sums up Germany’s Weimar Republic.

Can we not sum up the spirit of consumerism in the US? “You have to be 21 years of age if you want to purchase booze. But you can buy and own a gun if you are 19”. (USA, 2018)

That is economics of death. Those who subscribe to consumerism as an indicator of nation’s Happiness would not want to know the economics of life. Life is cheap indeed if you can press lethal gun its hand give blank check to kill as much  with impunity. It is money in the bank for every empty cartridge. The same politicians who pillory  woman caught in economic mire for undergoing abortion turn a blind eye on gun control. These are the ones who make ‘Right to own a gun as a badge of ‘courage’.What is Dutch courage and what we see now: a man feels ‘naked’ without a gun? Where integrity of man has gone to I wonder. It is the ‘bone spur’ of our times  and shake it before the Army so you may excuse from serving the nation when it needs you most.

Would the 19 year school shooter have had the guns had President Trump let safety controls in place?

Tailspin: Decree revoking gun sales to those with severe mental problems was Trump’s own doing. He signed the bill rolling back 2013 Obama era strict back ground checks into law without a photo op or fanfare. The president welcomed cameras into the oval office Tuesday for the signing of other executive orders and bills. The NRA“applauded” Trump’s action (ack: NBC news).

Couple of days ago the news was something shocking as well as tragic: “Thirteen siblings ‘held captive’ by parents in Perris, California: ‘Deeply religious’ couple arrested on torture charges.”

An earlier news reported that all thirteen appeared to be children, so deputies were “shocked” to discover that seven of them are adults. Capt. Fellows of the Riverside County Sheriff’s Department said “If you can imagine being 17 years old and appearing to be a 10-year-old, being chained to a bed, being malnourished and the injuries associated with that — I would call that torture.” The biological parents, David Allen Turpin, 57, and Louise Anna Turpin, 49, have been arrested on charges of torture and child endangerment, authorities said.

Our conventional concept of family has taken a terrible beating and for any thinking person it must lead to soul searching. As a Christian it made me wonder: Is this what a couple deeply religious as reported in the press would do to their own flesh and blood?Deeply religious do sometimes equally bad as the Turpins did.  They will show by example how to keep a lie in circulation and yet be pillars of their Christian community. It is what their activism and evangelicalism would mean to others. Christ is merely a talking point but not believed or followed. Otherwise what is the point in castigating LGBT or abortion laws? What made you a judge, hypocrite, when God alone is the judge?

A family is a snapshot of the nation where the parents in a Christian home are as vital as the President of the nation. He has to set the highest example for others to note and follow. The case of the Turpins is all the more relevant considering the despicable standard the White House has set. Is this what a lie when conceived should look like? The President is the head of all, races ethnic groups rich or poor across the political spectrum; besides being the steward of the citizenry his ‘stable genius’ would lay in nurturing  the environment, health of the sea, rivers and natural resources.

Think of Noah in the ark, which was built according to the specifications God gave him. He also brought the creatures under his care. Think of nations as the ark and while it is negotiating its way across  every governor is to think of a safe haven and not to give postures of their preeminence over others. Suppose Noah or members of his family had created rift in the harmony enjoined on the whole by God what catastrophe it could have caused? Modern nations are no different. Man cannot quite bring it off by his selfishness or greed and expect peace among nations.

“Am I my brother’s keeper?”
