About Universal RuleThis weblog is a personal notebook. I'll write about working in the information technology (IT) environment: notes and hints on how to survive in this rapidly changing world.
This weblog is work in progress. I'll focus on science, IT, and writing. These are the three topics I have been involved for the most of my working life.
In addition to short daily entries, I'm planning on including longer texts. Here are links to some examples:
I have noticed that some of the opinion pieces do not feel like I had written them. That is partly due to my lack of English, and partly due to writing without polishing. Usually I read, edit, and rewrite my texts 4-7 times. Here I'm not doing that, partly because of lack of time, and partly because I don't want blogging to be too serious. So far I have written 4852 postings to this weblog.
About Cellular AutomataI studied cellular automata (CA) for my masters thesis about ten years ago. Now the topic is again popular due to Stephen Wolfram's book A New Kind of Science. However, I'm a sceptic of the promises made by Wolfram.
In any case, the name I gave to this site is from CA terminology, pointing to a cellular automaton which is capable of universal computation. Here is an illustration of a CA in action (using Mathematica software):
About the AuthorMy science background is in physics and applied mathematics. Since graduating I have worked for about 12 years in the field of computational science: supercomputers, applied mathematics, numerical analysis, programming, and mathematical software.
My name is printed on the cover of about 50 books. I have published about 300 articles in journals, newspapers and magazines. I have also organized about two dozen courses, some short 1-5 day courses, some longer full semester courses and seminars.
Currently I manage a multi-disciplinary group of experts. I also have a small career as a columnist for an IT magazine in Finland.
