Darwinian evolution of computers and other inorganic machines

One of the most important discoveries of the last 200 years was Darwin’s theory of evolution. You are almost certainly educated in the ways and whys and wherefores of evolution, but here’s a quick recap: through multiple generations of a species, there is a process which ensures the survival of the fittest and the demise of the weakest. At its most basic, this process whittles out bad DNA mutations and embraces the good — but extrapolated out through billions of years, and it is the reason that girls prefer taller boys, and why we instinctively revere the leaders and generals of our society.

Why We Crave Creativity but Reject Creative Ideas
ScienceDaily (Sep. 5, 2011) — Most people view creativity as an asset -- until they come across a creative idea. That's because creativity not only reveals new perspectives; it promotes a sense of uncertainty.

Olber's Paradox
In astrophysics and physical cosmology, Olbers' paradox is the argument that the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe. It is one of the pieces of evidence for a non-static universe such as the current Big Bang model. The argument is also referred to as the "dark night sky paradox" The paradox states that at any angle from the Earth the sight line will end at the surface of a star, so the night sky should be completely white. This contradicts the darkness of the night sky and leads many to wonder why we do not see only light from stars in the night sky (see physical paradox).MORE HERE

Impossible motion: magnet-like slopes - Koukichi Sugihara
Top 10 finalist of the Best Visual Illusion of the Year Contest 2010
Koukichi Sugihara
Meiji Institute for Advanced Study of Mathematical Sciences, Japan
In this video, wooden balls roll up the slopes just as if they are pulled by a magnet. The behavior of the balls seems impossible, because it is against the gravity. The video is not a computer graphic, but a real scene. What is actually happening is that the orientations of the slopes are perceived oppositely, and hence the descending motion is misinterpreted as ascending motion. This illusion is remarkable in that it is generated by a three-dimensional solid object and physical motion, instead of a two-dimensional picture.
