More Noise

This time using random numbers from random.org.





I still see periodic patterns, but, again, maybe this should be double-blind.

The human brain never ceases to amaze me.

"A huge fraction of our brain is devoted to vision. One of the neglected features of our visual system is that the raw image falling on the retina is severely blurred: while most people can see with a resolution of about 1 arcminute (one sixtieth of a degree) under any daylight conditions, bright or dim, the image on our retina is blurred through a point spread function of width as large as 5 arcminutes (Wald and Grin, 1947; Howarth and Bradley, 1986). It is amazing that we are able to resolve pixels that are twenty-five times smaller in area than the blob produced on our retina by any point source."

David MacKay, Information Theory, Inference and Learning Algorithms, p. 565
