Sopdet (Spdt, lit. 'Triangle' or 'Sharp One')
In modern transcription, her name usually appears as Sopdet (Spdt, lit. 'Triangle' or 'Sharp One'), after the known Greek and Latin form Sothis (Σῶθις, Sō̂this). During the Old Kingdom, she was an important goddess of the annual flood and a psychopomp guiding deceased pharaohs through the Egyptian underworld. During the Middle Kingdom, she was primarily a mother and nurse and, by the Ptolemaic period, she was almost entirely subsumed into Isis.

Sothis

(Sopdet) Sothis is the way the Greeks wrote the name of the Goddess whose name appears in hieroglyphic Egyptian as ‘Sopdet’. Sothis is the deity immanent in the star Sirius, which in addition to being the brightest star in the sky, also played a key role in the Egyptian calendar. The Egyptian new year was fixed to the heliacal rising of Sirius, that is, the first day on which Sirius is visible before dawn after a period of invisibility which, in the case of Sirius, is about seventy days. The heliacal rising of Sirius varies depending upon the observer’s latitude; at Egypt’s latitude, this event would have occurred in late July. The heliacal rising of Sirius was particularly significant for Egyptians because it marked the beginning of the period within which the Nile’s annual inundation could be expected, and all Egyptian agriculture depended upon the Nile’s inundation. Sothis is depicted as a woman wearing a crown like the White Crown of Upper Egypt, but with antelope horns at the sides, like the crown worn by Satis, with the addition of a five-pointed star at the top. Sothis has for consort Sah, the deity immanent in the constellation of Orion, and is the mother of Soped. Both Sirius and Orion undergo a period of invisibility during which they are in the netherworld, but they emerge again and thus are symbols of resurrection.

PT utterance 216 says that Orion (Sah) and Sothis are “swallowed up by the Netherworld, pure and living in the horizon,” i.e., they depart alive; so too the deceased king says “I am swallowed up by the Netherworld, pure and living in the horizon. It is well with me and with them, it is pleasant for me and for them, within the arms of my father, within the arms of Atum.” In the Pyramid Texts, the relationship between the deceased king and Sothis is either that of the son or of the consort, in which latter case the Morning Star is said to be their offspring. This union is frequently identified with that of Isis and Osiris, as in PT utterance 366: “Your sister Isis comes to you [the deceased] rejoicing for love of you. You have placed her on your phallus and your seed issues into her, she being ready [seped] as Sothis [Sopdet], and Horus-Soped has come forth from you as Horus who is in Sothis.” In PT utterance 477 Sothis is called the beloved daughter of Osiris “who prepares yearly sustenance for you [Osiris; not here identified with the deceased king] in this her name of ‘Year’ and who guides me [the deceased king] when I come to you.” In PT utterance 509, the deceased king affirms that “I ascend to the sky among the Imperishable Stars [i.e., the northern circumpolar stars], my sister is Sothis, my guide is the Morning Star, and they grasp my hand at the Field of Offerings,” a location in the northeastern sky. In CT spell 467 (cp. BD spell 110), for becoming lord of the Field of Offerings, and which details a number of sites within this place, it is said of the “Town of the Great Lady” that “Sothis speaks to me [the deceased] in her good time,” perhaps the heliacal rising of Sirius. PT utterance 569 indicates that the heliacal rising of Sirius could be seen as the “birth” of Sothis. PT utterance 609 says of the deceased king, “Your sister is Sothis, your offspring is the Morning Star, and you shall sit between them on the great throne which is in the presence of the Two Enneads [a general term conveying the sense of ‘all the Gods’],” while it is said in PT utterance 691A of Re that “his brother is Orion [Sah], his sister is Sothis, and he sits between them in this land forever.” CT spell 6, which speaks of the resurrection of the deceased at the new moon festival, it said of the deceased that “You suck at your mother Sothis as your nurse who is in the horizon, while CT spells 36 and 37 affirm that the deceased has been “ennobled in the House of Sothis.” CT spell 44 invokes Sah, Sothis, and the Morning Star to encircle the deceased, saying “may they set you within the arms of your mother Nut, may they save you from the rage of the dead who go head-downwards,” an idiom in Egyptian afterlife literature for those lacking awareness in the netherworld, “for you are not among them and you shall not be among them, you shall not go down to the butchery of the first of the decade,” referring to the ‘death’ suffered by decanal stars when they disappear for seventy days, as is explained in a text from Papyrus Carlsberg I, where it is said of these stars that “one dies and another life every ten days,” in a cycle of death and rebirth which is “the life of [these] stars,” (Neugebauer and Parker, vol. I, 68). This death of stars each decan might trigger the ‘second death’ of souls who do have not the means of fixing their state. The stars themselves suffer no ill fate for undergoing this cycle, however, as is clear from the deceased’s affirmation in BD spell 149 that “I have eaten of the foods of the field of offerings, being gone down to the meadow of the stars that set.” The role of certain stars, such as Sirius, the stars in Orion, and the Morning Star, was apparently to assist in the transition to a state of permanence. CT spell 469 and its much-abbreviated version, CT spell 470, serve to equip the operator to be among the spirits “belonging to … He of the Dawn,” who is “ever between the two great Gods when they are in the sky, one of them in the west of the sky and one of them in the east of the sky.”

Soped: Phonemogram spd (Sopdu)

(Sopd, Sopdu, Sopedu) Soped’s name apparently comes from an Egyptian word meaning, literally, ‘sharp’, but which also bore a similar range of metaphorical meanings to that which ‘sharp’ has in English, i.e., ‘skilled’ or ‘effective’. The literal ‘sharpness’ which is said of Soped is that of his beak (e.g., “sharp of teeth” in PT utterance 222), for he is depicted often as a hawk, especially with a headdress of two tall plumes (these plumes possibly an astral phenomenon of some kind, viz. CT spell 61, “you shine in the plumes of Soped”) and a flail perched at his shoulder. Soped is also depicted anthropomorphically in the manner of a native of what was the far east for Egyptians, namely the Sinai and Arabia, for Soped characteristically represents the direction of the east in all of its connotations, both political and cosmological. When he appears in anthropomorphic form, Soped wears the beaded-and-tasselled shesmet belt (see Shesmetet) and his plumed headdress. Soped is regarded as the son of Sah (the constellation Orion) and Sothis (Sopdet; the star Sirius). His consort is Khensut.

In a text spoken by Geb in PT utterance 306, it is said of the deceased king that “the Fields of Rushes worship you in this your name of Dwaw [‘dawn’] as Soped who is under his ksbt-trees,” the Fields of Rushes being a marshy place in the east of the sky from which the sun emerges at dawn, while the ksbt is a type of fruit-bearing tree frequently associated with Soped but not readily identifiable. A significant reference to Soped begins in PT utterance 578 with an address to the deceased king as Osiris, saying “you shall not go into these eastern lands, you shall go into those western lands by the road of the Followers of Re,” apparently referring to an undesirable eastern entry to the netherworld which is referred to in certain other texts (e.g., CT spell 548/BD spell 93, “Not to ferry a man to the east in the realm of the dead,” also called, “Spell for not dying again in the realm of the dead”). The entourage of Osiris is charged with announcing him (i.e., the deceased) to Re “as one whose left arm is raised,” an apparent reference to the gesture of the raised arm which has the power to ward off evil forces and which is symbolically represented by the flail poised over the upraised arm, a symbolism especially associated with Min. The text goes on to identify the deceased king with Soped, in whose name the king takes into his embrace certain unidentified persons, of whom it is said only that “You [the deceased] do not know them … You it is who prevent them from becoming inert in your embrace; you go up to them empowered, effective … in this your name of Soped. Your flail is in your hand, your sceptre is at your hand, the slayers fall on their faces at you, the Imperishable Stars [the northern circumpolar stars] kneel to you.” Apparently, the eastern realm of the netherworld, in which certain unfortunate dead are slain a second time, and which is not a suitable place for Osiris, is to be penetrated by Soped, who subdues the slayers and rescues the anonymous dead from oblivion. CT spell 458, however, “Not to die a second time in the realm of the dead,” opposes Horus and Soped: the deceased affirms, “the messengers of Soped have no power over me, for I am Horus, son of Osiris,” and Soped is clearly charged with performing executions in the netherworld in an ancient commentary on BD spell 17 and in BD spell 130. CT spell 783 affirms of the deceased, “your son Soped the sharp-toothed acts as a protector from whoever would harm you in the eastern desert.”

(Rest/Vesper) West 🢦 East (Dawn/Rise)

According to ancient traditions such as वास्तु शास्त्र, vāstu śāstra — the "science of architecture" — the best direction to sleep in is toward the south, a theory also supported by recent research.


When in bed the head is pointed south and the feet are pointed north

Research has found that animals, such as cattle and deer, naturally align their bodies in a north-south direction when they are eating or resting. Additionally, preliminary research shows that when people switch to sleeping in a southward-facing direction, their blood pressure lowers and their sleep quality improves.

The Earth’s electromagnetic field may offer an explanation for this, according to some research and वास्तु शास्त्र, vāstu śāstra.

वास्तु शास्त्र, vāstu śāstra is an ancient architectural tradition, texts on the traditional Indian system of architecture. Practitioners view buildings as living organisms that can be designed in harmony with the energy of the universe. The concept leans on Hindu mythology and beliefs, such as the human body has its own north and south poles, similar to the Earth.

While there is no research connecting headaches and sleep direction, there is some evidence that sleeping toward the south may reduce the risk of high blood pressure. One study compared people who slept in an east-west direction versus a north-south direction. After a period of three months, those who slept in the north-south orientation had lower blood pressure, better sleep quality, and longer sleep overall. As a result, the researchers concluded that sleeping in alignment with the Earth’s electromagnetic field could improve sleep quality.

When sleeping toward the south, according to वास्तु शास्त्र, vāstu śāstra, we line up our body’s magnetic energy with that of the Earth. Our “north pole,” or our head, is oriented towards the Earth’s south pole, so opposite poles can attract. When we lie the other way, we have two similar poles facing each other, which practitioners believe may contribute to headaches and high blood pressure.

The past and present wilt—I have fill'd them, emptied them.
And proceed to fill my next fold of the future.

Listener up there! what have you to confide to me?
Look in my face while I snuff the sidle of evening,
(Talk honestly, no one else hears you, and I stay only a minute longer.)

Do I contradict myself?
Very well then I contradict myself,
(I am large, I contain multitudes.)

I concentrate toward them that are nigh, I wait on the door-slab.

Who has done his day's work? who will soonest be through with his supper?
Who wishes to walk with me?

Will you speak before I am gone? will you prove already too late?




I Contain Multitudes
 Bob Dylan, Track 1 on Rough and Rowdy Ways, 2020

Today, and tomorrow, and yesterday, too
The flowers are dyin' like all things do
Follow me close, I’m going to Bally-na-Lee
I'll lose my mind if you don't come with me
I fuss with my hair, and I fight blood feuds
I contain multitudes

Got a tell-tale heart like Mr Poe
Got skeletons in the walls of people you know
I’ll drink to the truth and the things we said
I'll drink to the man that shares your bed
I paint landscapes, and I paint nudes
I contain multitudes
A red Cadillac and a black moustache
Rings on my fingers that sparkle and flash
Tell me, what's next? What shall we do?
Half my soul, baby, belongs to you
I rollick and I frolic with all the young dudes
I contain multitudes

I'm just like Anne Frank, like Indiana Jones
And them British bad boys, the Rolling Stones
I go right to the edge, I go right to the end
I go right where all things lost are made good again
I sing the songs of experience like William Blake
I have no apologies to make
Everything's flowing all at the same time
I live on a boulevard of crime
I drive fast cars, and I eat fast foods
I contain multitudes

Pink pedal-pushers, red blue jeans
All the pretty maids, and all the old queens
All the old queens from all my past lives
I carry four pistols and two large knives
I'm a man of contradictions, I'm a man of many moods
I contain multitudes

You greedy old wolf, I'll show you my heart
But not all of it, only the hateful parts
I’ll sell you down the river, I’ll put a price on your head
What more can I tell you? I sleep with life and death in the same bed
Get lost, madame, get up off my knee
Keep your mouth away from me
I'll keep the path open, the path in my mind
I’ll see to it that there's no love left behind
I'll play Beethoven's sonatas, Chopin’s preludes
I contain multitudes

The Universe Is Not Locally Real,
and the Physics Nobel Prize Winners Proved It
Elegant experiments with entangled light have laid bare a profound mystery at the heart of reality

By Daniel Garisto on October 6, 2022

John Stewart Bell (1928-1990), was the Northern Irish physicist whose work sparked a quiet revolution in quantum physics.

One of the more unsettling discoveries in the past half-century is that the universe is not locally real. “Real,” means that objects have definite properties independent of observation—an apple can be red even when no one is looking; “local” means objects can only be influenced by their surroundings, and that any influence cannot travel faster than light. Investigations at the frontiers of quantum physics have found that these things cannot both be true. Instead, the evidence shows objects are not influenced solely by their surroundings and they may also lack definite properties prior to measurement. As Albert Einstein famously bemoaned to a friend, “Do you really believe the moon is not there when you are not looking at it?”

This is, of course, deeply contrary to our everyday experiences. To paraphrase Douglas Adams, the demise of local realism has made a lot of people very angry and has been widely regarded as a bad move.

Blame for this achievement has now been laid squarely on the shoulders of three physicists: John Clauser, Alain Aspect and Anton Zeilinger. They equally split the 2022 Nobel Prize in Physics “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.” (“Bell inequalities” refers to the pioneering work of the Northern Irish physicist John Stewart Bell, who laid the foundations for this year’s Physics Nobel in the early 1960s.) Colleagues agreed that the trio had it coming, deserving this reckoning for overthrowing reality as we know it. “It is fantastic news. It was long overdue,” says Sandu Popescu, a quantum physicist at the University of Bristol. “Without any doubt, the prize is well-deserved.”

“The experiments beginning with the earliest one of Clauser and continuing along, show that this stuff isn’t just philosophical, it’s real—and like other real things, potentially useful,” says Charles Bennett, an eminent quantum researcher at IBM. 

“Each year I thought, ‘oh, maybe this is the year,’” says David Kaiser, a physicist and historian at the Massachusetts Institute of Technology. “This year, it really was. It was very emotional—and very thrilling.”

Quantum foundations’ journey from fringe to favour was a long one. From about 1940 until as late as 1990, the topic was often treated as philosophy at best and crackpottery at worst. Many scientific journals refused to publish papers in quantum foundations, and academic positions indulging such investigations were nearly impossible to come by. In 1985, Popescu’s advisor warned him against a PhD in the subject. “He said ‘look, if you do that, you will have fun for five years, and then you will be jobless,’” Popescu says.

Today, quantum information science is among the most vibrant and impactful subfields in all of physics. It links Einstein’s general theory of relativity with quantum mechanics via the still-mysterious behaviour of black holes. It dictates the design and function of quantum sensors, which are increasingly being used to study everything from earthquakes to dark matter. And it clarifies the often-confusing nature of quantum entanglement, a phenomenon that is pivotal to modern materials science and that lies at the heart of quantum computing.

“What even makes a quantum computer ‘quantum’?” Nicole Yunger Halpern, a National Institute of Standards and Technology physicist, asks rhetorically. “One of the most popular answers is entanglement, and the main reason why we understand entanglement is the grand work participated in by Bell and these Nobel Prize–winners. Without that understanding of entanglement, we probably wouldn’t be able to realize quantum computers.”

FOR WHOM THE BELL TOLLS

The trouble with quantum mechanics was never that it made the wrong predictions—in fact, the theory described the microscopic world splendidly well right from the start when physicists devised it in the opening decades of the 20th century.

What Einstein, Boris Podolsky and Nathan Rosen took issue with, laid out in their iconic 1935 paper, was the theory’s uncomfortable implications for reality. Their analysis, known by their initials EPR, centred on a thought experiment meant to illustrate the absurdity of quantum mechanics; to show how under certain conditions the theory can break—or at least deliver nonsensical results that conflict with everything else we know about reality. A simplified and modernized version of EPR goes something like this: Pairs of particles are sent off in different directions from a common source, targeted for two observers, Alice and Bob, each stationed at opposite ends of the solar system. Quantum mechanics dictates that it is impossible to know the spin, a quantum property of individual particles prior to measurement. When Alice measures one of her particles, she finds its spin to be either up or down. Her results are random, and yet, when she measures up, she instantly knows Bob’s corresponding particle must be down. At first glance, this is not so odd; perhaps the particles are like a pair of socks—if Alice gets the right sock, Bob must have the left.

But under quantum mechanics, particles are not like socks, and only when measured do they settle on a spin of up or down. This is EPR’s key conundrum: If Alice’s particles lack a spin until measurement, how then when they whiz past Neptune do they know what Bob’s particles will do as they fly out of the solar system in the other direction? Each time Alice measures, she effectively quizzes her particle on what Bob will get if he flips a coin: up, or down? The odds of correctly predicting this even 200 times in a row are 1 in 1060—a number greater than all the atoms in the solar system. Yet despite the billions of kilometres that separate the particle pairs, quantum mechanics says Alice’s particles can keep correctly predicting, as though they were telepathically connected to Bob’s particles.

Although intended to reveal the imperfections of quantum mechanics, when real-world versions of the EPR thought experiment is conducted the results instead reinforce the theory’s most mind-boggling tenets. Under quantum mechanics, nature is not locally real—particles lack properties such as spin up or spin down prior to measurement, and seemingly talk to one another no matter the distance.

Physicists sceptical of quantum mechanics proposed that there were “hidden variables,” factors that existed in some imperceptible level of reality beneath the subatomic realm that contained information about a particle’s future state. They hoped in hidden-variable theories, nature could recover the local realism denied to it by quantum mechanics.

“One would have thought that the arguments of Einstein, Podolsky and Rosen would produce a revolution at that moment, and everybody would have started working on hidden variables,” Popescu says.

Einstein’s “attack” on quantum mechanics, however, did not catch on among physicists, who by and largely accepted quantum mechanics as is. This was often less a thoughtful embrace of nonlocal reality, and more a desire to not think too hard while doing physics—a head-in-the-sand sentiment later summarized by the physicist David Mermin as a demand to “shut up and calculate.”

The lack of interest was driven in part because John von Neumann, a highly regarded scientist, had 1932 published a mathematical proof ruling out hidden-variable theories. (Von Neumann’s proof, it must be said, was refuted just three years later by a young female mathematician, Grete Hermann, but at the time no one seemed to notice.)

Quantum mechanics’ problem of nonlocal realism would languish in a complacent stupor for another three decades until being decisively shattered by Bell. From the start of his career, Bell was bothered by the quantum orthodoxy and sympathetic toward hidden variable theories. Inspiration struck him in 1952 when he learned of a viable nonlocal hidden-variable interpretation of quantum mechanics devised by fellow physicist David Bohm—something von Neumann had claimed was impossible. Bell mulled the ideas over for years, as a side project to his main job working as a particle physicist at CERN.

In 1964, Bell rediscovered the same flaws in von Neumann’s argument that Hermann had. And then, in a triumph of rigorous thinking, Bell concocted a theorem that dragged the question of hidden variables from its metaphysical quagmire onto the concrete ground of experiment.

Normally, hidden-variable theories and quantum mechanics predict indistinguishable experimental outcomes. What Bell realized is that under precise circumstances, an empirical discrepancy between the two can emerge. In the eponymous Bell test (an evolution of the EPR thought experiment), Alice and Bob receive the same paired particles, but now they each have two different detector settings—A and a, B and b. These detector settings allow Alice and Bob to ask the particles different questions; an additional trick to throwing off their apparent telepathy. In local hidden-variable theories, where their state is preordained and nothing links them, particles cannot outsmart this extra step, and they cannot always achieve the perfect correlation where Alice measures spin down when Bob measures spin up (and vice versa). But in quantum mechanics, particles remain connected and far more correlated than they could ever be in local hidden-variable theories. They are, in a word, entangled.

Measuring the correlation multiple times for many-particle pairs, therefore, could prove which theory was correct. If the correlation remained below a limit derived from Bell’s theorem, this would suggest hidden variables were real; if it exceeded Bell’s limit, then the mind-boggling tenets of quantum mechanics would reign supreme. And yet, in spite of its potential to help determine the very nature of reality, after being published in a relatively obscure journal Bell’s theorem languished unnoticed for years.

THE BELL TOLLS FOR THEE

In 1967, John Clauser, then a graduate student at Columbia University, accidentally stumbled across a library copy of Bell’s paper and became enthralled by the possibility of proving hidden-variable theories correct. Clauser wrote to Bell two years later, asking if anyone had actually performed the test. Clauser’s letter was among the first feedback Bell had received.

With Bell’s encouragement, five years later Clauser and his graduate student Stuart Freedman performed the first Bell test. Clauser had secured permission from his supervisors, but little in the way of funds, so he became, as he said in a later interview, adept at “dumpster diving” to secure equipment—some of which he and Freedman then duct-taped together. In Clauser’s setup—a kayak-sized apparatus requiring careful tuning by hand—pairs of photons were sent in opposite directions toward detectors that could measure their state or polarization.

Unfortunately for Clauser and his infatuation with hidden variables, once he and Freedman completed their analysis, they could not help but conclude that they had found strong evidence against them. Still, the result was hardly conclusive, because of various “loopholes” in the experiment that conceivably could allow the influence of hidden variables to slip through undetected. The most concerning of these was the locality loophole: if either the photon source or the detectors could have somehow shared information (a plausible feat within the confines of a kayak-sized object), the resulting measured correlations could still emerge from hidden variables. As Kaiser puts it pithily, if Alice tweets at Bob which detector setting she’s in, that interference makes ruling out hidden variables impossible.

Closing the locality loophole is easier said than done. The detector setting must be quickly changed while photons are on the fly—“quickly” meaning in a matter of mere nanoseconds. In 1976, a young French expert in optics, Alain Aspect, proposed a way for doing this ultra-speedy switch. His group’s experimental results, published in 1982, only bolstered Clauser’s results: local hidden variables looked extremely unlikely. “Perhaps Nature is not so queer as quantum mechanics,” Bell wrote in response to Aspect’s initial results. “But the experimental situation is not very encouraging from this point of view.”

Other loopholes, however, still remained—and, alas, Bell died in 1990 without witnessing their closure. Even Aspect’s experiment had not fully ruled out local effects because it took place over too small a distance. Similarly, as Clauser and others had realized, if Alice and Bob were not ensured to detect an unbiased representative sample of particles, they could reach the wrong conclusions.

No one pounced to close these loopholes with more gusto than Anton Zeilinger, an ambitious, gregarious Austrian physicist. In 1998, he and his team improved on Aspect’s earlier work by conducting a Bell test over a then-unprecedented distance of nearly half a kilometre. The era of divining reality’s nonlocality from kayak-sized experiments had drawn to a close. Finally, in 2013, Zeilinger’s group took the next logical step, tackling multiple loopholes at the same time.

“Before quantum mechanics, I actually was interested in engineering. I like building things with my hands,” says Marissa Giustina, a quantum researcher at Google who worked with Zeilinger.  “In retrospect, a loophole-free Bell experiment is a giant systems-engineering project.” One requirement for creating an experiment closing multiple loopholes was finding a perfectly straight, unoccupied 60-meter tunnel with access to fibre optic cables. As it turned out, the dungeon of Vienna’s Hofburg palace was an almost ideal setting—aside from being caked with a century’s worth of dust. Their results, published in 2015, coincided with similar tests from two other groups that also found quantum mechanics as flawless as ever.

BELL’S TEST REACHES THE STARS
 
One great final loophole remained to be closed, or at least narrowed. Any prior physical connection between components, no matter how distant in the past, has the possibility of interfering with the validity of a Bell test’s results. If Alice shakes Bob’s hand prior to departing on a spaceship, they share a past. It is seemingly implausible that a local hidden-variable theory would exploit these loopholes, but still possible.

In 2017, a team including Kaiser and Zeilinger performed a cosmic Bell test. Using telescopes in the Canary Islands, the team sourced its random decisions for detector settings from stars sufficiently far apart in the sky that light from one would not reach the other for hundreds of years, ensuring a centuries-spanning gap in their shared cosmic past. Yet even then, quantum mechanics again proved triumphant.

One of the principal difficulties in explaining the importance of Bell tests to the public—as well as to sceptical physicists—is the perception that the veracity of quantum mechanics was a foregone conclusion. After all, researchers have measured many key aspects of quantum mechanics to a precision of greater than 10 parts in a billion. “I actually didn’t want to work on it. I thought, like, ‘Come on; this is old physics. We all know what’s going to happen,’” Giustina says. But the accuracy of quantum mechanics could not rule out the possibility of local hidden variables; only Bell tests could do that.

“What drew each of these Nobel recipients to the topic, and what drew John Bell himself, to the topic was indeed [the question], ‘Can the world work that way?’” Kaiser says. “And how do we really know with confidence?” What Bell tests allow physicists to do is remove the bias of anthropocentric aesthetic judgments from the equation; purging from their work the parts of human cognition that recoil at the possibility of eerily inexplicable entanglement, or that scoff at hidden-variable theories as just more debates over how many angels may dance on the head of a pin. The award honours Clauser, Aspect and Zeilinger, but it is a testament to all the researchers who were unsatisfied with superficial explanations about quantum mechanics, and who asked their questions even when doing so was unpopular.

“Bell tests,” Giustina concludes, “are a very useful way of looking at reality.”
