At the core of good science and engineering is the careful and respectful treatment of data. We calibrate our instruments, scrutinize the algorithms we use to process the data, and study the behavior of the models we use to interpret the data or simulate the phenomena we may be observing. Surprisingly, this careful treatment of data often breaks down when we visualize our data.
"The observers of this unusual visual stimulus reported seeing the borders between the stripes gradually disappear, and the colors seem to flood into each other. Amazingly, the image seemed to override their eyes' opponency mechanism, and they said they perceived colors they'd never seen before."
"...we see on the ground a number of spots of light, scattered irregularly, some large, some small..."
The Nature of Light and Color in the Open Air "Moreover, this book is written for all those who love Nature; for the young people going out into the wide world and gathering together round the camp-fire; for the painter who admires but does not understand the light and colour of the landscape; for those living in the country; for all who delight in travelling; and also for town-dwellers, for whom, even in the noise and clamour of our dark streets, the manifestations of Nature remain." - Marcel Minnaert [more inside]
The "terminator" is the dividing line between day and night as seen from on high. This shadow line is diffuse and shows the gradual transition to darkness we experience as twilight. [more inside]
Da gebt der Natur die Ehre/ Froh, an Aug' und Herz gesund/ Und erkennt der Farbenlehre/ Allgemeinen ewigen Grund!
Goethe's Theory of Colors: example of a "research style" that has "played a crucial role in the history of physics", or "tedious heap of mythical, uninformed or impressionistic color anecdotes"? Learn more about "Goethian science", then miss the point entirely by viewing a PDF recreating his experiments photographically, or playing with his triangle online. [more inside]
i began cataloging the colors, and put the color list on the web. over time, the paint catalog turned into a web site.
Not settled after all partial genetic explaination of eye color. it's not one classic dominant/recessive allele a la the monk Mendel. three known + unknown genes involved, everybody's still beautiful.
