How a movie changed one man’s vision forever

How a movie changed one man’s vision

Good movies change people’s view of the world all the time, but how many can say a movie has fundamentally altered their vision forever? One person who can is Bruce Bridgeman. In terms of how he sees the world, there is life before Hugo, and life after Hugo.
On 16 February this year, Bridgeman went to the theatre with his wife to see Martin Scorsese’s 3D family adventure. Like everyone else, he paid a surcharge for a pair of glasses, despite thinking they would be a complete waste of money. Bridgeman, a 67-year-old neuroscientist at the University of California in Santa Cruz, grew up nearly stereoblind, that is, without true perception of depth. “When we’d go out and people would look up and start discussing some bird in the tree, I would still be looking for the bird when they were finished,” he says. “For everybody else, the bird jumped out. But to me, it was just part of the background.”
All that changed when the lights went down and the previews finished.Almost as soon as he began to watch the film, the characters leapt from the screen in a way he had never experienced. “It was just literally like a whole new dimension of sight. Exciting,” says Bridgeman.
But this wasn’t just movie magic. When he stepped out of the cinema, the world looked different. For the first time, Bridgeman saw a lamppost standing out from the background. Trees, cars and people looked more alive and more vivid than ever. And, remarkably, he’s seen the world in 3D ever since that day. “Riding to work on my bike, I look into a forest beside the road and see a riot of depth, every tree standing out from all the others,” he says. Something had happened. Some part of his brain had awakened.
Conventional wisdom says that what happened to Bridgeman is impossible. Like many of the 5-10% of the population living with stereoblindness, he was resigned to seeing a world without depth. What Bridgeman experienced in the theatre has been observed in clinics previously – the most famous case being Sue Barry, or “Stereo Sue”, who according to the author and neurologist Oliver Sacks first experienced stereovisionwhile she was undergoing vision therapy. Her visual epiphany came during the course of professional therapy in her late-forties. The question is why after several decadesof living in a flat, two-dimensional world did Bridgeman’s brain spontaneously begin to process 3D images?

The truth about technology’s greatest myth

(Thinkstock)

Lecturing in late 1968, the American sociologist Harvey Sacks addressed one of the central failures of technocratic dreams. We have always hoped, Sacks argued, that “if only we introduced some fantastic new communication machine the world will be transformed.” Instead, though, even our best and brightest devices must be accommodated within existing practices and assumptions in a “world that has whatever organisation it already has.”
As an example, Sacks considered the telephone. Introduced into American homes during the last quarter of the 19th Century, instantaneous conversation across hundreds or even thousands of miles seemed close to a miracle. For Scientific American, editorializing in 1880, this heralded “nothing less than a new organization of society – a state of things in which every individual, however secluded, will have at call every other individual in the community, to the saving of no end of social and business complications…”
Yet the story that unfolded was not so much “a new organization of society” as the pouring of existing human behaviour into fresh moulds: our goodness, hope and charity; our greed, pride and lust. New technology didn’t bring an overnight revolution. Instead, there was strenuous effort to fit novelty into existing norms.
The most ferocious early debates around the telephone, for example, concerned not social revolution, but decency and deception. What did access to unseen interlocutors imply for the sanctity of the home – or for gullible or corruptible members of the household, such as women or servants? Was it disgraceful to chat while improperly dressed? Such were the daily concerns of 19th-century telephonics, matched by phone companies’ attempts to assure subscribers of their propriety.
As Sacks also put it, each new object is above all “the occasion for seeing again what we can see anywhere” – and perhaps the best aim for any writing about technology is to treat novelty as not as an end, but as an opportunity to re-scrutinize ourselves.
I’ve been writing this fortnightly column since the start of 2012, and in the last two years have watched new devices and services become part of similar negotiations. By any measure, ours is an age preoccupied with novelty. Too often, though, it offers a road not to insight, but to a startling blindness about our own norms and assumptions.
Take the litany of numbers within which every commentary on modern tech is couched. Come the end of 2014, there will be more mobile phones in the world than people. We have moved from the launch of modern tablet computing in mid-2011 to tablets likely accounting for over half the global market in personal computers in 2014. Ninety per cent of the world’s data was created in the last two years. Today’s phones are more powerful than yesterday’s supercomputers. Today’s software is better than us at everything from chess to quiz shows. And so on.
Singularity myth
It’s a story in which both machines and their capabilities increase for ever, dragging us along for the exponential ride. Perhaps the defining geek myth of our age, The Singularity, anticipates a future in which machines cross an event horizon beyond which their intellects exceed our own. And while most people remain untouched by such faith, the apocalyptic eagerness it embodies is all too familiar. Surely it’s only a matter of time – the theory goes – before we finally escape, augment or otherwise overcome our natures and emerge into some new phase of the human story.
Or not. Because – while technological and scientific progress is indeed an astonishing thing – its relationship with human progress is more aspiration than established fact. Whether we like it or not, acceleration cannot continue indefinitely. We may long to escape flesh and history, but the selves we are busy reinventing come equipped with the same old gamut of beauties, perversities and all-too-human failings. In time, our dreams of technology departing mere actuality – and taking us along for the ride – will come to seem as quaint as Victorian gentlemen donning evening dress to make a phonecall.
This is one reason why, over the last two years, I’ve devoted a fair share of columns to the friction between the stories we tell about tech and its actual unfolding in our lives. From the surreptitious erosion of digital history to the dumbness of “smart” tech, via email’s dirty secrets and theimportance of forgetfulness, I love exploring the tensions between digital tools and analogue selves – not because technology is to be dismissed or deplored, but because it remains as mired in history, politics and human frailty as everything else we touch.
This will be the last regular Life:Connected column I write for BBC Future. Instead, I’ll be writing a book about one of my obsessions: attention, and how its quantification and sale have become a battleground for 21st Century selves. I will, however, continue examining technology’s impact here and elsewhere – and asking what it means to watch ancient preoccupations poured into fresh, astounding moulds.
On which note: what do you think is most ripe for abandonment ar

The surprising downsides of being clever

It's hard to be the smartest person in the room (Credit: Getty Images)

If ignorance is bliss, does a high IQ equal misery? Popular opinion would have it so. We tend to think of geniuses as being plagued by existential angst, frustration, and loneliness. Think of Virginia Woolf, Alan Turing, or Lisa Simpson – lone stars, isolated even as they burn their brightest. As Ernest Hemingway wrote: “Happiness in intelligent people is the rarest thing I know.”
The harsh truth is that greater intelligence does not equate to wiser decisions — In fact, it can make you more foolish
The question may seem like a trivial matter concerning a select few – but the insights it offers could have ramifications for many. Much of our education system is aimed at improving academic intelligence; although its limits are well known, IQ is still the primary way of measuring cognitive abilities, and we spend millions on brain training and cognitive enhancers that try to improve those scores. But what if the quest for genius is itself a fool’s errand?

The strangest sounds in the world

(Credit: Thinkstock)


“You know you were told to be nice and not to heckle?” Sophie Meekings asks her audience in the dingy cellar of the North London pub. “Well, you can heckle me if you want – it’s just there’s not much point, because I won’t be able to hear you.”
In the phantom word illusion, people hear everything from ‘rainbow’ to ‘mango’  — What do you hear? (see below)
She’s only partly joking. Meekings is profoundly deaf and would struggle to make out the conversations around her. The subject of her talk is, in fact, hearing – and the strange tricks our ears can play on the mind.
To explore the theme, she plays some auditory illusions, which are among the strangest sounds I have ever heard. What strikes me is just how easily the eerie and futuristic sounds divide the audience. Like the viral furore #TheDress, which prompted radically different interpretations of colour, the audio clips she played – and others like them – challenge our assumptions about how we each perceive the world.
We’re often told that seeing isn’t believing, but I had never realised just how fragile and deceptive our hearing can be, too. Once I have left the pub’s cellar and made my way to the hustle and bustle of King’s Cross Station, I begin to wonder just how much of what I hear is created by my brain. My soundscape will never be quite the same way again.

Ceres' bright spots back in view

Ceres


The mysterious bright spots on the dwarf planet Ceres are back in view.
Nasa's Dawn spacecraft, which arrived at the mini-world on 6 March, is now settling into its first science orbit some 13,500km above the surface.
The probe's approach took it around the back of the dwarf and on to the night side, hiding the spots from the camera system and remote sensing instruments.
But with each passing day, Dawn is seeing more sun-lit terrain - including now its most enigmatic features.
The newly released sequence of images were acquired a week ago when the probe was still some 22,000km from the surface.
Nonetheless, they clearly show the brightest spot and its companion standing out against the darker landscape.
The science team on the US space agency mission do not yet have a name for the location, referring to it simply still as Region, or spot, 5.
Quite why the spots should reflect sunlight so efficiently in comparison to their surroundings is uncertain. It hints at the presence of ice - but ice would not be stable on an airless body. Another suggestion is salts, perhaps left behind after exposed ices had vaporised.
What is intriguing is that not all bright spots on Ceres are the same in nature. Another spot location, known as region 1, is very much cooler than the terrain that surrounds it. Region 5 displays no such behaviour.
Chris Russell, the principal investigator on Dawn, told BBC News last week: "It may be a surface composition situation in that the different material at that particular spot conducts heat differently than in the other area. So, the first thing you go to when you see different temperatures is the different thermal conductivity of the surface material."
Dawn will conduct an intense observational campaign starting this week, with the data being downlinked in early May. Scientists should then have something more definitive to say about Ceres and its enthralling spots.

Mediterranean capsized migrants' boat's captain charged


The Tunisian captain of a boat that capsized off Libya on Sunday, killing hundreds of migrants, has been charged with reckless multiple homicide, Italian officials say.
He has also been charged along with a Syrian member of the crew with favouring illegal immigration.
The two were among 27 survivors who arrived in Sicily late on Monday.
A UNHCR spokeswoman has told the BBC the migrants' boat capsized after merchant vessels came too close to it.
Carlotta Sami of the United Nations High Commissioner for Refugees in Italy was at the Sicilian port of Catania to meet the survivors. Some 800 people are thought to have died in the disaster, she said.
There were nationals of Syria, Eritrea, Somalia, Mali, Sierra Leone and Senegal on board, kept in three different layers in the boat.
"They left on Saturday morning around eight o'clock in the morning from Tripoli, and they started to have problems, and they were approached by merchant vessels during the night around 10 o'clock.
"They were big merchant vessels and probably in the wrong place; they went too close and at some point crashed, and the little boat lost its balance, and people started to move around.
"Those that were down wanted to come up and vice-versa, and many people fell into the water, and then the boat capsized."

South Korea in turmoil over corruption scandal


Sometimes things just don't run right for politicians.
Lee Wan-koo only became prime minister of South Korea in February after a tough parliamentary fight for confirmation, during which a recording of him surfaced in which he boasted of his ability to suppress bad press coverage.
The recording of how he could soften bad news became... bad news.
And then, two months into the job, a construction tycoon, Sung Wan-jong,committed suicide amid swirling allegations of corruption.
Mr Sung left a suicide note - a suicide accusation, would be more accurate - in which he named those whom he claimed had taken his tainted money.
The South Korean prime minister's name was on that list.
The resignation came shortly after the prime minister had declared an "all-out war" on corruption, saying the government would mobilise all its resources to root it out.
Mr Lee initially showed no sign of vacating his seat, denying the allegations - and then after a weekend of feverish speculation - he offered his resignation, still denying the allegations.

Damage to president

It should be said that the prime minister is not the most powerful person in the land - that is the president - but the prime minister is her right-hand man.
He recommends ministers and oversees the daily routine of government. He is next in line if she falls in an emergency.

How Gareth Bale and Real Madrid sleep their way to the top



At 1pm every afternoon, the hustle and bustle of Real Madrid's Valdebebas training ground grinds to a halt and the facility resembles a ghost town.
A silence descends over the complex for the following two hours as players and staff close their eyes and drift into a siesta before waking and resuming their day - but they're not sleeping on the job.
The scene is a window into football's relentless pursuit of marginal gains as clubs across Europe turn to technology, purpose-built facilities and sleep experts to recharge their multi-million pound assets and gain a competitive advantage.

You snooze, you win

Tennis great Roger Federer and basketball star LeBron James are both advocates of sleeping for upwards of 10 hours per night  and research shows the performance benefits of proper rest for athletes.
A study by Stanford University sleep expert Cheri Mah  showed basketball players who increased their sleep duration to those levels improved shot accuracy by 9% in tests and recorded improved sprint and reaction times.
Take recovery for granted and the risks are great. One restless night is enough to weaken the immune system and increase the risk of illness. Sleep poorly for 64 hours or more and strength and power is reduced.

Profile: Oskar Groening, 'bookkeeper of Auschwitz'



Age poses a challenge for prosecutors trying to bring suspected Nazi war criminals to justice.
More than 70 years have passed since the liberation of the death camps and many of those involved have now died.
So the trial of Oskar Groening will be one of the last of its kind.
A former Nazi death camp guard, the 93-year-old is charged with at least 300,000 counts of accessory to murder.
Mr Groening, known as the "bookkeeper of Auschwitz", was allegedly responsible for counting banknotes confiscated from prisoners.
Prosecutors in Lueneburg, northern Germany, also allege that he hid victims' luggage away from new arrivals, to disguise the victims' fate.

Horrors of Auschwitz

Mr Groening, who began work at Auschwitz aged 21, admits witnessing the mass killing of Jews, but denies he was an "accomplice".
He has spoken publicly about his role in the camp - and it is that aspect of his case that observers such as Nazi hunter Efraim Zuroff say makes it particularly important.
"It's the first in recent history in which a defendant has talked [publicly] about the horrors of Auschwitz, that's something you almost never see," Mr Zuroff told the Wall Street Journal. last year.
Mr Groening was born in 1921 in Lower Saxony in Germany, and his mother died when he was four, Germany's Der Spiegel magazine reports.
His father, a proud nationalist, joined the Stahlhelm paramilitary group after Germany's defeat in World War One. His anger at how Germany had been treated under the Treaty of Versailles increased when his textile business went bankrupt in 1929.
The young Groening joined the Stahlhelm Youth in the early 1930s, and then the Hitler Youth. He later spoke of taking part in the Nazi burning of books written by Jews and others deemed "degenerate".

Need to speak up

British historian Laurence Rees says Mr Groening began training as a bank clerk at 17, but after war was declared, he decided he wanted to follow in his grandfathers' footsteps and join an "elite" unit in the German army.
He signed up to the Waffen SS and arrived in Auschwitz in 1942.
For about two years, Mr Groening allegedly counted money taken from the luggage of murdered Jews and sent it back to SS headquarters in Berlin. He also supervised luggage of prisoners being transported to the camp.
But when the war was over - and he was released from a British prison - he did not speak of his role at Auschwitz.
Instead he began a normal, middle-class life in Lueneburg Heath in Lower Saxony, where he worked at a glass-making factory until retirement.
It was not until he heard people denying the Holocaust had ever happened, decades later, that he suddenly felt the need to speak up.
"I saw the gas chambers. I saw the crematoria," he told the BBC in the 2005 documentary Auschwitz: the Nazis and the "Final Solution".

Russia sets its sights on Middle East




Russia's decision to go ahead with the sale of the advanced S-300 surface-to-air missile system to Iran has angered its critics in the West and alarmed the Israeli government in equal measure.
For some it has raised additional question-marks over the fate of any putative nuclear deal between Iran and the international community.
But more significantly it may also mark a renewed effort by Moscow to bolster its diplomatic profile in the Middle East.
The decision to sell the S-300 to Iran is not new, the contract goes back to at least the latter part of 2010.
But for a variety of reasons - concern about Iran's nuclear activities and with intense lobbying from Israel and the West - the Russians never went ahead and delivered the system.
It is not yet clear exactly which version of the S-300 will be sold to Iran.
It is no longer the most sophisticated of Russia's air defences, but it is nonetheless a highly capable system and much better than those the Israelis and Western air forces have faced in the region during recent campaigns.

Nuclear deal fears

Critics argue sophisticated air defences weaken the military threat against Iran, and thus weaken the pressure upon it to make and abide by a final nuclear deal.

Mediterranean migrant crisis: EU sets out measures



The EU has set out a package of measures to try to ease the migrant boat crisis in the Mediterranean.
Its Triton patrolling service will be strengthened and a military mandate sought to destroy people-smugglers' boats. An emergency summit of EU leaders will be held on Thursday.
As the EU ministers met, fresh distress calls from migrant boats were received.
The crisis worsened at the weekend when hundreds of migrants were feared drowned as a boat capsized off Libya.
Libyan question
The EU's foreign policy chief, Federica Mogherini, said the 10-point package set out at talks in Luxembourg was a "strong reaction from the EU to the tragedies" and "shows a new sense of urgency and political will".
"We are developing a truly European sense of solidarity in fighting human trafficking - finally so."
