Shubunkin Shubunkins. Blue is the most prized colour in Shubunkins. Calico originally denoted three coloured varieties of goldfish that did not include blue. The best blues are produced from line breeding of good blue specimens of Shubunkins. Sometimes good blues may be obtained by breeding bronze (metallic) with "pink" (matte-scaled) goldfish, but a grey slate colour may result instead. It may take several months for the nacreous coloration to develop on a young fry (baby fish). Shubunkins are excellent pond fish because they reach a length of at adulthood. A Shubunkin goldfish is considered an adult at 2 to 3 years
A New Kind of Science of traffic, material fracture, crystal growth, biological growth, and various sociological, geological, and ecological phenomena. Another feature of simple programs is that, according to the book, making them more complicated seems to have little effect on their overall complexity. "A New Kind of Science" argues that this is evidence that simple programs are enough to capture the essence of almost any complex system. In order to study simple rules and their often complex behaviour, Wolfram argues that it is necessary to systematically explore all of these computational systems and document what they do. He further argues that this study should
