Hello, my background is in chemistry and physics, with a main interest in explosives and home made rocket engines. I live on Brazil, speak English, Portuguese and a little of Spanish. In my off-time, I read a lot on books and on the internet, and I have discovered that Wikipedia is a good, growing, source for information in that department. I'm not very good at writting about my self, so that's it.
