I'm here to answer questions in my area of expertise when I have spare time. I guess this knowledge database is set up to answer some common questions that we all have in our minds. Knowledge is for share, however I dislike finishing homework for others, so I'll never answer those questions. Familar areas: Science: bio, biochem, chem, phys chem, stats, pharmacology, chem engineering Academia and research Other interests: desserts, paranormal, entertainment news, hk news..... and many others Questions are welcome.
