  • In “Consciousness Explained,” a 1991 best-seller, he described consciousness as something like the product of multiple, layered computer programs running on the hardware of the brain. Many readers felt that he had shown how the brain creates the soul. Others thought that he’d missed the point entirely. To them, the book was like a treatise on music that focussed exclusively on the physics of musical instruments. It left untouched the question of how a three-pound lump of neurons could come to possess a point of view, interiority, selfhood, consciousness—qualities that the rest of the material world lacks. These skeptics derided the book as “Consciousness Explained Away.”
  • The physicalists believe, with Dennett, that science can explain consciousness in purely material terms. The dualists believe that science can uncover only half of the picture: it can’t explain what Nabokov called “the marvel of consciousness

    "Memory plays a big part in shaping our identity, but can we rely on what we recall about ourselves and about others? Mike Williams finds out how human memory works and why some memories flood back more easily than others. He also explores whether different senses trigger different types of memories. Mike speaks to memory experts Martin Conway, Elizabeth Loftus, Gisli Gudjonsson, Maria Larsson and Simon Chu. The reader is Roberto Pistolesi."

    "Mikael Vejdemo-Johansson, a mathematician in Stockholm, recently led a small team on a quest to discern how many tie knots are possible. Their results, uploaded to arXiv, say there are 177,147 different ways to tie the knot of a necktie. That is 177,062 more ways than were found in 1999 by Cambridge mathematicians Yong Mao and Thomas Fink, who arrived at 85 possible ways to tie a tie. Why the discrepancy?"

  • As Cooke first set out developing his idea, he turned to his former classmate at Oxford University, Princeton neuroscientist Greg Detre, to help update his tried-and-tested techniques with the latest understanding of memory. Together, they came up with some basic principles that would guide Memrise’s progress over the following years. The first is the idea of “elaborative” learning – in which you try to give extra meaning to a fact to try to get it to stick in the mind. These “mems”, as the team call them, are particularly effective if they tickle the funny bone as well as the synapses – and so for each fact that you want to learn, you are encouraged to find an amusing image or phrase that helps plant the memory in your mind.
  • Unsurprisingly, it was the friendly competition element that captured the attention of Traynor's primary school pupils learning Spanish. “As soon as they come into the classroom, they want to see where they are on the leader board,” he says. And there are other advantages. Each lesson, Traynor tends to split the class into two – while half are doing the “spade work” on vocabulary learning on the school's iPads, he can teach the others – before the two halves switch over. By working with these smaller groups, he can then give more individual attention to each child's understanding of the grammar.Even more powerfully, Traynor recently began encouraging his class to record and upload their pronunciation of the words onto the app – which they can then share with their classmates using the course. The sound of their classmates seems to have spurred on their enthusiasm, says Traynor. “They're constantly trying to work out whose voice they're hearing,” he says. “So they're giving more attention to the different sounds. I think it's improved their speaking and listening dramatically.”Although most courses on Memrise deal with foreign languages, teachers in other subjects are also starting to bring the technology to their classroom. Simon Birch from The Broxbourne School in Hertfordshire, for instance, uses it to teach the advanced terminology needed for food technology exams, while his school’s English department are using it to drill spelling. "The benefits for literacy can't be overstated," Birch says.

    "Researchers today are no less interested in how physical appearance shapes political and economic outcomes. Half a century after Kennedy debated Nixon, the economist Daniel Hamermesh, from the University of Texas, coined the portmanteau pulchrinomics, the economic study of beauty. Hamermesh and his colleagues have produced a large body of research that is fascinating, if disconcerting: the basic principle of pulchrinomics is that beauty drives economic success."

  • n revamping its SAT test for college admission, the College Board is making the essay portion optional. The written assessment was controversial since it was introduced in 2005, with some college officials expressing little confidence in what it demonstrated or how it was scored. But since an increasing number of college students are taking remedial reading and writing classes, shouldn’t the essay be mandatory? Is the bigger question, how can, or should, writing be judged?

    "As a young man James's girlfriends were flavoured of rhubarb and melted wine gums. And his schoolmates had a strong essence of sliced potatoes and strawberry jam. He chose his companions not based on their personality or looks, but because of how their names tickled his taste buds. James Wannerton has synaesthesia - a condition in which the senses mix together so that sensations we normally consider separate start to intermingle."

  • "Time" is something that both philosophers and physicists have been wondering for about, well, a long time. And now, the neuroscientists have joined in. They have found a man who, when he looks at you, hears what you are saying to him before your lips move.
  • Now you might not realise this, but in terms of vision you are always living 0.3 second (or 300 milliseconds) behind reality. That's how long it takes between when the incoming light lands on the cells in your retina, and you get that full magnificent wraparound 3D colour sensation that we call vision.
  • We don't notice this delay in reality because we have evolved to be able to deal with this. We can anticipate actions or patterns through experience.
  • ...1 more annotation...
  • So how come we normally see the lips moving at the same time as we hear the voice? Almost certainly, it's because our brain deliberately inserts a delay of about 200 milliseconds on the audio circuit. Now sure, there would be an advantage in being able to hear dangerous things, such as the killer kangaroo bearing down upon you that extra 200 milliseconds earlier. But all of us are a product of an evolutionary pathway that decided it was more important for us to be able to easily communicate with our fellow humans, than to hear the killer kangaroo that 200 milliseconds sooner. After all, we humans are quite pathetic as a hunting animal. We can't run very quickly, our eyes are not very sharp, and neither is our sense of smell. Our claws are silly little fingernails, and our teeth are not very good at ripping and tearing. But thanks to our amazing brain, we can organise ourselves into groups and so we have become masters of the planet. So, getting back to Mr PH, if the sound of the outside world was deliberately electronically delayed by 200 milliseconds, suddenly audio and vision were in sync for him again. And when the neuroscientists did an MRI scan on his brain, they found damage in areas that were well-placed to disrupt audition and/or timing.

    ""A lot of people think intuition is general purpose, but intuition is actually domain specific," said Massimo Pigliucci, a philosophy professor at City University of New York, and author of Answers for Aristotle: How Science and Philosophy Can Lead Us to A More Meaningful Life. "Intuition is the result of your subconscious brain picking up on clues and hints and calculating the situation for you, and that's based solely on experience.""
