b'Computer scientist Bernard Chazelle has an original take on what music works in us \\u2014 especially the music of Johann Sebastian Bach. Just as mathematicians talk about discovering rather than inventing great equations, so, he says, Bach set out to \\u201cdiscover\\u201d the musical rules behind the universe. After hearing this conversation, you may never listen to any piece of music \\u2014 whether Bach or Jay-Z \\u2014 in quite the same way again.'
