Guest Posted June 26, 2014 Posted June 26, 2014 why the grass is green and the sky is blue, etc why the grass is green Chlorophyll only processes the blue and red parts of electromagnetic spectrum radiation so we perceive the green unused bit. why the sky is blue Sunlight is scattered by molecules of atmospheric gas, blue light has the shortest wavelength which is why we perceive it abundantly on a clear sunny day when the sun is directly above us. When it's low on the horizon light waves are travelling through more atmospheric gas and reflective dust before they reach our eyes. Blue is re-scattered more frequently than the longer wavelength red, orange and yellow which accounts for our spectacular golden dawns and rosy dusks. Incidentaly many 19th century artists such the English watercolourist JMW Turner and French impressionist Edgar Degas were known for their spectacular dawn and dusk scenes. Both were working during a prolific period of volcanic eruptions, the so called 'years without summer', or 'eighteen hundred and froze to death'.

Cynical Misanthrope Posted June 26, 2014 Posted June 26, 2014 It's funny how a few keeps saying that everyone has their own preference/taste but then go on and bash how the mouth and nose are aligned wrong xD Just as Sadomaschist said, I found all of them beautiful in their own right.

Well what else to expect of a species that spends it's fleeting, willfully contradictory life mired in oxymora like 'geek chic' and runways full of 'beautiful ugly' people wafting about in clothes we pretend to admire but wouldn't be seen dead in.
