George Musser in Science:
Nearly 60 years ago, the Nobel Prize–winning physicist Eugene Wigner captured one of the many oddities of quantum mechanics in a thought experiment. He imagined a friend of his, sealed in a lab, measuring a particle such as an atom while Wigner stood outside. Quantum mechanics famously allows particles to occupy many locations at once—a so-called superposition—but the friend’s observation “collapses” the particle to just one spot. Yet for Wigner, the superposition remains: The collapse occurs only when he makes a measurement sometime later. Worse, Wigner also sees the friend in a superposition. Their experiences directly conflict.
Now, researchers in Australia and Taiwan offer perhaps the sharpest demonstration that Wigner’s paradox is real. In a study published this week in Nature Physics, they transform the thought experiment into a mathematical theorem that confirms the irreconcilable contradiction at the heart of the scenario. The team also tests the theorem with an experiment, using photons as proxies for the humans. Whereas Wigner believed resolving the paradox requires quantum mechanics to break down for large systems such as human observers, some of the new study’s authors believe something just as fundamental is on thin ice: objectivity. It could mean there is no such thing as an absolute fact, one that is as true for me as it is for you.
“It’s a bit disconcerting,” says co-author Nora Tischler of Griffith University. “A measurement outcome is what science is based on. If somehow that’s not absolute, it’s hard to imagine.”

IN 1953, ISAIAH BERLIN published his long essay “The Hedgehog and the Fox,” outlining his now-famous Oxbridge variant on there are two kinds of people in this world. He drew the title from an ambiguous fragment attributed to the ancient lyric poet Archilochus of Paros: “The fox knows many things, but the hedgehog one big thing.” Written with the aim of pointing out tensions between Tolstoy’s grand view of history and the artistic temperament that saw such a view as untenable, Berlin’s essay became an unlikely hit, although less for its argument about Russian literature than for its contention that two antithetical personae govern the world of ideas: hedgehogs, who view the world in terms of some all-embracing system, seeing all facts as fitting into a grand pattern; and foxes, those pluralists or particularists who refuse “big theory” for reasons either intellectual or temperamental.
Physicists have traditionally simplified systems as much as possible, in order to shed light on fundamental properties. But small, simple parts build up into large, complex wholes. Are there new rules and laws of nature that apply specifically to the realm of complexity? This has been a popular question for a few decades now, and we have some answers but not as many as we would like. Neil Johnson is an expert on complex systems generally, and information networks in particular. We discuss how self-organization can arise from individual units following their own agendas, and how we can mathematically characterize such behavior. Then we talk about information networks in the modern world, including how they have been used to spread disinformation and find recruits for radical fringe groups.

That the Latin name for the caper flower, Capparis spinosa, is related to the Italian word capriolare (meaning ‘to jump in the air’), is a droll enough visual/verbal play to suggest that Titian is intentionally teasing us with the placement of the prickly perennial plant directly under the bouncing Bacchus. But it is the plant’s medicinal use, since antiquity, as a natural carminative (or remedy for excessive flatulence) that reveals the artist is truly letting rip with some mischievous fun. In the context of Titian’s carefully deployed caper, Bacchus’s explosive propulsion from his seat appears more wittily, if crudely, choreographed by Titian, who demystifies the lovestruck levitation by providing us with a more down-to-earth explanation for the cheeky lift-off. In Titian’s retelling of Ovid’s myth, Bacchus has been hoisted by his own pungent petard, as Shakespeare, who likewise loved toilet humour, might have said.
The original Garden of Emptiness, Kyle Chayka explains in his pugnacious whistlestop tour of minimalism, is to be found in the 16th-century rock garden of the Kyoto Zen temple Ryoan-Ji. Chayka journeys to this sacred spot in search of the philosophical minimalism that has been obscured by today’s commodified decluttering. His book, which ranges from the Stoics and Buddhism to Mies van der Rohe, is a rebuke to the Shintoistic declutterer Marie Kondo, whose bestselling Netflix-powered KonMari method urges us to retain only those possessions that ‘spark joy’ and to practise such techniques as folding trousers vertically and not – heavens! – horizontally. Chayka warms to Donald Judd’s Plexiglas, Philip Johnson’s Glass House and Brian Eno’s ‘Discreet Music’. He is irked by minimalist hipsters’ all-grey uniforms and the solipsistic sensory deprivation of the Soulex company’s amniotic ‘float spas’. But such businesses are booming. In hard times, many go minimal by default, yet others pay handsomely for the ultimate postmodern lifestyle commodity, which, Kayla observes, they can of course never possess: nothing.
In 1994, the term ‘straight to TV movie’ was used mostly as an insult. So when a small film called The Last Seduction premiered on HBO, nobody expected much. But those who caught it were floored by a darkly comic noir thriller with a knockout performance from Linda Fiorentino as Bridget Gregory. Bridget is a smart-talking New Yorker who hits ‘cow country’ with a suitcase of cash her husband Clay (Bill Pullman) had acquired in a drug deal. Advised to lie low for a while, Bridget shacks up with smitten local Mike (Peter Berg) and uses him to enact a devious plan. Directed by John Dahl and written by Steve Barancik, The Last Seduction is bitterly funny and deliciously clever – the razor-sharp dialogue is loaded with one-liners. It’s also sexy in a way that appeals to both women and men. With its manipulative femme fatale, it touches on similar themes to the big-budget Basic Instinct – but many believe it does it much better.

This, Clive James’s final book, is a collection of his writings on Larkin and his work. James takes his title from the final words of Larkin’s ‘The Whitsun Weddings’ (1959). The ninety four pages, which include copies of one manuscript letter and two typed letters from Larkin to James, don’t offer very much book for your money, but you do get Clive James, who’s always good value. His explanation of why Jack Nicholson is the only Hollywood actor appropriate to play Larkin onscreen justifies the price of admission.
In July 1925, Margaret Mead, a doctoral student at Columbia University, set off on a cross-country train journey with a young faculty member, Ruth Benedict. Mead was bound for the west coast and then American Samoa, her first fieldwork expedition as a junior anthropologist. Benedict was stopping in New Mexico to study myth and ritual in the Zuni Pueblo. The journey took them through Ohio to Illinois, across the prairie, then south toward the deserts. It was the longest the two of them had ever spent together, certainly the longest without their husbands in tow.
Recently, researchers at MIT published a study that looks into autonomous vehicle mobility, employment and policy. The research found that self-driving vehicles will happen later than sooner.
It is becoming clear that many of our nation’s children could be attending school from home for this school year and possibly longer. If educators and families aren’t empowered with the right support and tools, this will evolve from an education crisis to an education catastrophe.
Since 1964, the presidential candidate who has won Florida and its 29 electoral college votes has also won the White House in every election except 1992. In that time, the constant has not been whether Florida goes for Republicans or Democrats – both parties have been in power in the past three decades – but that the vote has been close. In 2016, Donald Trump won with 48.6 per cent of the vote compared to Hillary Clinton’s 47.4 percent. In 2008, Barack Obama had 51 percent, compared to John McCain’s 48.2. And no one, of course, can forget the 2000 election, which
