A mind reading machine has edged closer to reality after scientists found a way of converting thoughts into words.

Line segments in the golden ratio A golden rectangle with longer side a and shorter side b , when placed adjacent to a square with sides of length a , will produce a similar golden rectangle with longer side a + b and shorter side a . This illustrates the relationship The golden ratio ( ) is also called the golden section (Latin: sectio aurea ) or golden mean .
