Living Code: The importance of visual programming
Python has a well-earned reputation for being easy to use and to learn, at least for people who have learned programming in other languages first. Lately my kids have been very interested in programming, and I've found that Python doesn't come as easily to 6-11 year olds as it does to adult programmers. So I see two approaches to this problem, if it is a problem. One, let them use other languages than Python.

I usually don’t blog about my personal shopping experience, but a recent experience forced me to publish this post. I travel a lot for business, so for Valentine’s Day I decided to order a bouquet of flowers for my wife. Well knowing that online flower delivery is a trivial online commodity these days, I opened up Google and searched for “flower delivery”. One of the first hits was an allegedly Australian company, ReadyFlowers.com.au , which promoted their special same-day Valenti ne’s Day delivery of high quality roses.
Instances of Fractal Evolution « Mindsoul’s Weblog
When couple of years ago (Nov 2006) I experienced author and biologist Dr. Bruce Lipton ‘s 2-day presentation in his seminar produced by Spirit 2000 in San Francisco, I was totally blown away by the depth of insight I got into how my biology, my health, and how my health at the cellular level, is in my complete control through my beliefs (both conscious and subconscious). But one new thing Bruce added at the end of his presentation was his talk about how patterns of life and evolution are similar to patterns of fractal geometry. Dr. Lipton who has done decades of research on cellular biology, talks about this in detail in the article called Fractal Evolution he wrote and published on his site . Fractal geometry is derived by a recursive mathematical formulas, and incredible shapes were produced when computers were strong and fast enough to be able to execute these very computing-intensive formulas.
In general usage, complexity tends to be used to characterize something with many parts in intricate arrangement. The study of these complex linkages is the main goal of complex systems theory . In science [ 1 ] there are at this time a number of approaches to characterizing complexity, many of which are reflected in this article.

Self-similarity of complex networks
(Submitted on 3 Mar 2005) Abstract: Complex networks have been studied extensively due to their relevance to many real systems as diverse as the World-Wide-Web (WWW), the Internet, energy landscapes, biological and social networks \cite{ab-review,mendes,vespignani,newman,amaral}. A large number of real networks are called ``scale-free'' because they show a power-law distribution of the number of links per node \cite{ab-review,barabasi1999,faloutsos}. However, it is widely believed that complex networks are not {\it length-scale} invariant or self-similar. This conclusion originates from the ``small-world'' property of these networks, which implies that the number of nodes increases exponentially with the ``diameter'' of the network \cite{erdos,bollobas,milgram,watts}, rather than the power-law relation expected for a self-similar structure. Nevertheless, here we present a novel approach to the analysis of such networks, revealing that their structure is indeed self-similar.Chaos - Scholarpedia
Chaos describes a system that is predictable in principle but unpredictable in practice. In other words, although the system follows deterministic rules, its time evolution appears random. In dynamical systems theory, the term chaos is applied to deterministic systems that are aperiodic and that exhibit sensitive dependence on initial conditions.
The complexity of a physical system or a dynamical process expresses the degree to which components engage in organized structured interactions. High complexity is achieved in systems that exhibit a mixture of order and disorder (randomness and regularity) and that have a high capacity to generate emergent phenomena. Complexity across Scientific Disciplines Despite the importance and ubiquity of the concept of complexity in modern science and society, no general and widely accepted means of measuring the complexity of a physical object, system, or process currently exists.
