you say 'galazio', i say 'blue'

from physorg:

'dr athanasopoulos explains: “our language forces us to cut up the world in different ways. greek speakers systematically use two different terms to refer to blue: the sky is ghalazio (light blue), never ble (dark blue), and a blue pen is ble but can never be ghalazio. english speakers would have no problem calling both the sky and a pen blue in an instant.”'

and

'the researchers found differences in visual processing of light and dark blues between greek and english speakers as early as 100 milliseconds, suggesting that indeed, speakers of different languages literally have differently structured minds.'

the rest just a click away.
