The Colour of the Sky
The Colour of the Sky

Alfred Russel Wallace;

摘要(Abstract):

<正>1If we look at the sky on a perfectly fine summer’s day we shall find that the blue colour is the most pure and intense overhead,and when looking high up in a direction opposite to the sun.Near the horizon it is always less bright, while in the region immediately around the sun it is more or less yellow.
