#### INTERNET EXPLORER and WINDOWS USERS

You may download mathematics software here. Load the file into a new directory and run it. For details of use see install.htm

Recent developments: Linear cellular Automata, and health and nutrition data. Download DNA.EXE to a new folder, and then run it. You will see a scrolling dna molecule. Press CTRL-C when you are bored and you will see some pull down menus. From these you can access the documentation. There is also the full text of the General Public Licence (GPL)

You can download the latest source code and documentation on Windows/Linux compatability and other features. For that matter the file RNA.EXEis almost the same as DNA.EXE, except that there is mouse support, and the application runs a common linux/windows script.

#### Introduction to Life

Conway's Cellular Automata Game
http://www.radicaleye.com/lifepage
This site contains many links. CAs are now getting onto the maths syllabus in many schools and colleges. Various people think that CAs can provide the theory of everything. Although early simulations were practiced on a Go board it is very hard to design a CA to play Go. The 19x19 Go board became obsolete for tracking life generations once people could more easily use computers. Much modern research has been on positions where even a 1024x1024 high resolution display is no longer adequate to display the interesting areas.

Mathematics and Justice ? Well counting and so on is culture independent. There should be less influence of race, class and wealth in most of the World's justice systems.

#### AMERICAN PRESIDENTIAL ELECTIONS 2000

Ralph Nader's campaign was the razor which cut asunder the much hyped Amercan version of democracy. Since the 1890s combinatorial analysis has been used to analyse results from exit polls and rolling counts, while weighted voting systems have been seriously analysed since the inception of the UN Security Council in the 1940s. Mark Livingston of the University of North Carolina has written an excellent theoretical page.

#### DENOUNCE THE SINGLE CONVENTION ON NARCOTIC DRUGS

This is one of the more moronic pieces of legislation passed by the 'great and good' of the World. Prohibition was popular in the 1920s in the USA because they wanted to stop drinking, and also in the then colonial world since nationalist leaders in much of Asia were in great emotional pain because of the actions of the British capitalist classes in using Opium to balance the books of their then extensive overses empires. The Japanese control of Opium distribution in China during the 1930s lead to a reinforcement of these opinions.

Despite the UN CONVENTION intravenous drug use is rife in Eastern Europe and many people are catching AIDS/SIDA. The UN CONVENTION is a good example of a "harm maximisation" policy.

Your government signed you up to this treaty which requires the possession of a huge list of drugs including cannabis, ecstasy and heroin to be a criminal offence punishable by "imprisonment or other penalties of deprivation of liberty". The British foreign secretary, Robin Cook has been pleased to exhort countries such as Singapore and Malaysia to be yet more vigourous in enforcing these laws despite the fact that the Death Penalty is still fashionable for drug offences in these places.
