What science software is popular with schools, either for use with students or technical staff.

I have rasmol for both windows and Linux,

RasMol, http://www.umass.edu/microbio/rasmol/index2.htm , and the derived browser plug-in Chime are excellent pieces of software; they put a very friendly face on horribly difficult problems. (I've tried myself to write code to parse the same datafiles RasMol handles and it is extraordinarily difficult.) There are plenty of tutorials for RasMol/Chime---from elementary up to postgraduate level ---available on the Web: http://molvis.sdsc.edu/visres/ Unfortunately Protein Explorer, the new generation of RasMol-derived software, is Windows-only.

I also have a titration program (in french) and a program to calcuate molecular weight from a given formula.

If some could also please point me in the direction of sites for science technicians I would also be grateful, something on laboratory procedures, relating to schools.

At the MRC HGMP-RC, http://www.hgmp.mrc.ac.uk/ , we keep pages of useful links for lab workers in our Genome Web resource: http://www.hgmp.mrc.ac.uk/GenomeWeb/other-lists.html . The most useful of these for school-level use is probably this one: http://biobenchelper.hypermart.net/ . The BioBenchHelper main page links among other places to a small molecule section: http://biobenchelper.hypermart.net/small_m/small_molecules.htm . This includes links to pages on acids and bases, measurement and standards, chemical glossaries, calculation and periodic table pages. Hope this is useful. -- Damian COUNSELL http://www.counsell.com/
