RE: Reference 

Thanks for your concern on references. For the sake of record, I'm one of the early Wikipedians (13th or so) and English is not my native language. The major problems with Wikipedians are that 1. Majority of them believes in Google and wants references (Tamil and related topics are one of the worst affected in these aspect; as olden Tamil people were so adverse to document their names and many Tamil articles are not yet translated and can't stand for Google Test), 2. Others are always wrong mentalityinstead of trying to contribute or improve, 3. Reverting without reading the articlejust because it contradicts their belief (Remember Science itself is a changing thing and olden theories are now lies). Sorry for the lengthy lamentation; but, I hope you can understand the problems and solutions. Thanks.
