WS is a professional, living on and playing with chemistry, biochemistry and molecular biology (and biology, electronics and computers, if in doubt). Actually, it's hard for him to draw hard lines and -more important- he strongly believes that it's absolutely unnecessary and impossible, too: Problems want to be solved and unknown things lurk for discovery!

Who dares to care about disciplines? It's all chemistry, anyway *^_^*

As in the past, I have learned a lot from various scientific newsgroups and mailing lists, I hope that I am now able to return to the community a bit of the knowledge and experience that I was able to obtain in 15 years of working as scientist. I encourage you to do the same!
