Evolutionary theorists question whether there's an adaptive purpose to dreaming
The neurologist Richard Cytowic discusses what synesthesia can teach us about ordinary perception, creativity and Vladimir Nabokov
In practice, entanglement is an extremely delicate condition. Background disturbances readily destroy the state—a bane for quantum computing in particular, because calculations are done only as long as the entanglement lasts. But for the first time, quantum physicist Seth Lloyd of the Massachusetts Institute of Technology suggests that memories of entanglement can survive its destruction. He compares the effect to Emily Brontë’s novel Wuthering Heights: “the spectral Catherine communicates with her quantum Heathcliff as a flash of light from beyond the grave.”
Daniel Tammet is the author of two books, Born on a Blue Day and Embracing the Wide Sky, which comes out this month. He’s also a linguist and holds the European record for reciting the first 22,514 decimal points of the mathematical constant Pi. Mind Matters editor Jonah Lehrer chats with Tammet about how his memory works, why the IQ test is overrated, and a possible explanation for extraordinary feats of creativity.
The brain can store a vast number of memories, so why can't we find these memories when we need to? A new study provides insights into this question.
Most scientists dismiss the vast majority of ghost sightings as hoaxes. But researchers in Canada, England and elsewhere are exploring what happens in the brain to create the illusion that something is "haunted." So far, they have found evidence that some apparitions may be brain benders caused by spiking EMFs (electromagnetic fields), and possibly even extremely low-–frequency sound waves (known as infrasound) so subtle that the ear does not register them as noise.
Popular tales do far more than entertain, however. Psychologists and neuroscientists have recently become fascinated by the human predilection for storytelling. Why does our brain seem to be wired to enjoy stories? And how do the emotional and cognitive effects of a narrative influence our beliefs and real-world decisions?
Can a lobster ever truly have any emotions? What about a beetle? Or a sophisticated computer? The only way to resolve these questions conclusively would be to engage in serious scientific inquiry—but even before studying the scientific literature, many people have pretty clear intuitions about what the answers are going to be.
A new approach to the decades-old problem of quantum gravity goes back to basics and shows how the building blocks of space and time pull themselves together.
