What is the role of memory in a digital age? - BBC News - 0 views

  • The digital age is also raising broader philosophical questions about memory. How much do we need to remember when it can be effortlessly recalled for us by a machine? If the use of search engines for retrieving facts is allowed at some point in the future, exams themselves might have to change.

How do you memorise an entire symphony? - BBC News - 0 views

  • Memorised music performance has interested scientists since as far back as the 1800s. One type of memory that musicians use is commonly called "muscle memory", but the memories are not actually stored in the muscles. Muscle memory instead refers to a type of "procedural" memory called motor learning, in which memories for movement patterns are acquired through repetition. Procedural memory is separate from other types of memory, such as our memory for events (autobiographical memory) or general knowledge about the world (semantic memory).

BBC - Future - The surprising downsides of being clever - 1 views

  • The first steps to answering these questions were taken almost a century ago, at the height of the American Jazz Age. At the time, the new-fangled IQ test was gaining traction, after proving itself in World War One recruitment centres, and in 1926, psychologist Lewis Terman decided to use it to identify and study a group of gifted children. Combing California’s schools for the creme de la creme, he selected 1,500 pupils with an IQ of 140 or more – 80 of whom had IQs above 170. Together, they became known as the “Termites”, and the highs and lows of their lives are still being studied to this day.
  • The harsh truth, however, is that greater intelligence does not equate to wiser decisions; in fact, in some cases it might make your choices a little more foolish. Keith Stanovich at the University of Toronto has spent the last decade building tests for rationality, and he has found that fair, unbiased decision-making is largely independent of IQ. Consider the “my-side bias” – our tendency to be highly selective in the information we collect so that it reinforces our previous attitudes. The more enlightened approach would be to leave your assumptions at the door as you build your argument – but Stanovich found that smarter people are almost no more likely to do so than people with distinctly average IQs.
  • A tendency to rely on gut instincts rather than rational thought might also explain why a surprisingly high number of Mensa members believe in the paranormal; or why someone with an IQ of 140 is about twice as likely to max out their credit card.Indeed, Stanovich sees these biases in every strata of society. “There is plenty of dysrationalia – people doing irrational things despite more than adequate intelligence – in our world today,” he says. “The people pushing the anti-vaccination meme on parents and spreading misinformation on websites are generally of more than average intelligence and education.” Clearly, clever people can be dangerously, and foolishly, misguided.

Aboriginal legends reveal ancient secrets to science - BBC News - 0 views

  • Scientists are beginning to tap into a wellspring of knowledge buried in the ancient stories of Australia's Aboriginal peoples. But the loss of indigenous languages could mean it is too late to learn from them.
  • "They describe this gigantic wave coming very far inland and killing everybody except those who were up on the mountaintops, and they actually name all the different locations where people survived," says Mr Hamacher. He and Mr Goff took core samples from locations between 500m and 1km (0.6 miles) inland, and at each spot, they found a layer of ocean sediment, about 2m down, indicating that a tsunami likely washed over the area hundreds, or possibly thousands, of years ago. The samples need further analysis but Mr Hamacher says it is a "very exciting" result that suggests the legend could be true.
  • They also employ a rigid kin-based, cross-generational system of fact-checking stories, involving grandchildren, parents, and elders, which Mr Reid says doesn't seem to be used by other cultures.

  • But there is a problem - Indigenous languages are dying off at an alarming rate, making it increasingly difficult for scientists and other experts to benefit from such knowledge. More than 100 languages have already become extinct since white settlement.

Does the digital era herald the end of history? - BBC News - 0 views

  • Data specialist EMC estimates that in 2013 the world contained about 4.4 zettabytes (4.4 trillion gigabytes) of data. By 2020, it expects this to have risen tenfold.History, in other words, has gone online. While this means unprecedented instant access to vast stores of human knowledge and culture, it also means that mountains of digital data of crucial importance to archivists and future historians are potentially under threat from deletion, corruption, theft, obsolescence and natural or man-made disasters.

The man who missed killing Hitler by 13 minutes - BBC News - 2 views

  • On 8 November 1939, Hitler was making his annual speech at a Munich beer hall. The event commemorated early Nazi struggles in the 1920s. This time Hitler used it to mock his international enemies, and boast about Germany's successful start to the war.But what neither Hitler nor the Nazi top brass and loyal audience realised was that, a few feet away from where the Fuehrer was standing, a bomb was about to go off . Its ticking timers carefully muffled in cork casing, it had been assembled and planted secretly over many weeks by Georg Elser. He had started making his plans the previous year, after deciding that, under Hitler, "war was unavoidable".Hitler began this speech at the same time every year, but on this occasion, eager to return to Berlin and his military planners, the Fuehrer left early.Thirteen minutes later, the bomb exploded, causing eight deaths and massive damage. The ceiling collapsed just above where Hitler had been standing.

BBC News - Stalin wiped from Soviet Gulag prison museum - 9 views

  • The director of a Russian museum at a Stalin-era prison camp says local officials have taken over the site and removed references to the Soviet dictator's crimes.
  • Millions of Soviet citizens were sent to labour camps in the notorious Gulag system, or shot, during Joseph Stalin's hardline communist rule. The worst repressions took place in the 1930s.
  • Portraits of Stalin - taboo after the scale of his crimes was revealed - have become more common since the collapse of the Soviet Union in 1991. Surveys indicate that many Russians now regard Stalin as a hero.

BBC News - A Point of View: The writer who foresaw the rise of the totalitarian state - 2 views

  • The 19th Century Russian novelist Fyodor Dostoyevsky wrote about characters who justified murder in the name of their ideological beliefs. For this reason, John Gray argues, he's remained relevant ever since, through the rise of the totalitarian states of the 20th Century, to the "war against terror".

The schools that had cemeteries instead of playgrounds - BBC News - 0 views

  • Canada's Truth and Reconciliation Commission has released its findings into more than a century of abuse in Indian Residential Schools. Between the 1880s and 1990s 150,000 aboriginal children were sent to institutions where they were stripped of their language and culture. Many faced emotional, physical and sexual abuse.
  • He said that seven generations of children were "stripped of the love of their families, their self-respect and … identity" over the course of a century.
  • He said there had been "discrimination, deprivation and all manner of physical, sexual, emotional and mental abuse".

Five bizarre 'lessons' in Indian textbooks - BBC News - 0 views

  • India, which has a literacy level well below the global average, has intensified its efforts in the field of education. In 2012 the country passed the Right to Education act which guarantees free and compulsory education for all children until the age of 14.However, some of the "facts" that have been found in textbooks around the country have given rise to speculation over what exactly passes for "education" in India.Glaring mistakes, downright lies and embellishments in textbooks are often featured in local media. A trend that is all the more worrying, given that India's education system promotes rote learning at the cost of analytical thinking.

Have 1,200 World Cup workers really died in Qatar? - BBC News - 0 views

  • But the Indian Government says in a press release: "Considering the large size of our community, the number of deaths is quite normal."The point officials are making is that there are about half a million Indian workers in Qatar, and about 250 deaths per year - and this, in their view, is not a cause for concern. In fact, Indian government data suggests that back home in India you would expect a far higher proportion to die each year - not 250, but 1,000 in any group of 500,000 25-30-year-old men. Even in the UK, an average of 300 for every half a million men in this age group die each year.Tim Noonan from the ITUC believes the comparison is misleading. The migrant workers in Qatar are not only young, they are fit. "Qatar requires them to be given a medical examination to screen them for pre-existing conditions, so this is comparing apples and pears," he says. Of course, India is a very poor country and Qatar is a very rich country - the richest in the world in terms of GDP per capita - so it's perfectly reasonable to say that Qatar should do better by its migrant workers. But then it is. So is the figure of 1,200 Qatar World Cup deaths just meaningless? No, says Tim Noonan. He denies the ITUC came up with the figure just to get headlines. In fact he thinks the real figure may well be higher. "To describe a problem is the correct thing to do," he says. "And we believe we've described it accurately and conservatively."

BBC World Service - Hardtalk, Medical Ethicist - Julian Savulescu - 1 views

  •  
    "From genetic engineering to bioscience, human beings are close to acquiring the ability not just to combat disease, but to enhance and perfect our species. But should we seek to do it, or should we shy away from a path that led to Nazi eugenics? Hardtalk speaks to the Australian born, Oxford based medical ethicist Julian Savulescu. Can we trust ourselves to be wise masters of our own biology?"

BBC - Culture - How the English language became such a mess - 0 views

  • First, the greed: invasion and theft. The Romans invaded Britain in the 1st Century AD and brought their alphabet; in the 7th Century, the Angles and Saxons took over, along with their language. Starting in the 9th Century, Vikings occupied parts of England and brought some words (including they, displacing the Old English hie). Then the Norman French conquered in 1066 – and replaced much of the vocabulary with French, including words which over time became beef, pork, invade, tongue and person.
  • Once the English tossed out the French (but not their words) a few centuries later, they started to acquire territories around the world – America, Australia, Africa, India. With each new colony, Britain acquired words: hickory, budgerigar, zebra, bungalow. The British also did business with everyone else and took words as they went – something we call “borrowing,” even though the words were kept. Our language is a museum of conquests.
  • Sometimes sounds just change capriciously. The most significant instance of this in English was the Great Vowel Shift. From the 1400s to about 1700, for reasons that remain unclear, our long vowels all shifted in our mouths like cream swirling slowly in a cup of tea. Before it, see rhymed with "eh"; boot was said like “boat”; and out sounded like “oot.” But when the sounds shifted, the spelling stayed behind.

  • One more layer of snobbery has added further complications across the Atlantic over the last couple of centuries: national pride. The (relatively few) American simplifications of spelling – color for colour, center for centre – largely owe their existence to Noah Webster’s desire to create a distinctive American English. Canadian preference for keeping many British spellings, on the other hand, has the same nationalistic origins… just in reverse.And now? Now we don’t even want to spell things as they sound. How do spellings like hed, hart, lafter, dotter, and det look to you? Uneducated, perhaps? Annoyingly simplistic? Exactly. We enjoy our discomforts – and we really enjoy arbitrary practices that allow us to tell who are and aren’t the “right sort”. We’ve taken a useful tool and turned it into a social filter.

BBC News - Artists 'have structurally different brains' - 1 views

  • Artists have structurally different brains compared with non-artists, a study has found. Participants' brain scans revealed that artists had increased neural matter in areas relating to fine motor movements and visual imagery. The research, published in NeuroImage, suggests that an artist's talent could be innate. But training and environmental upbringing also play crucial roles in their ability, the authors report. As in many areas of science, the exact interplay of nature and nurture remains unclear.
