“In an atmosphere of uniform density the most distant things seen through it, such as the mountains, in consequence of the great quantity of atmosphere which is between your eye and them, will appear blue. Therefore you should make the building... wall which is more distant less defined and bluer... five times as far away, make five times as blue.” ShouldEyeFiveBuildingWallMountainConsequenceBlueDefinedAtmosphereQuantityFar AwayUniformsDensityBuilding Walls Author:Leonardo da Vinci
“However small we are, we should always fight for what we believe to be right. And I don’t mean fight with the power of our fists or the power of our swords…I mean the power of our brains and our thoughts and our dreams. And as small and quiet and unimportant as our fighting may look, perhaps we might all work together…and break out of the prisons of our own making. Perhaps we might be able to keep this fierce and beautiful world of ours as free for all of us as it seemed to be on that blue afternoon of my childhood.” WorldShouldBelieveLooksMayMeanDreamMightAbleTogetherBeautifulFightingBrainBreakChildhoodQuietBluePrisonWorking TogetherAfternoonFierceOur ThoughtsOur DreamsFistsUnimportantBreak OutBeautiful World Author:Cressida Cowell
