Hello to all the members of Chemistry Forum, I am an ancient engineer stumbling around the fringes of chemistry. Re; white phosphorous blog, I totally agree with Mir's comments on the subject. I find it sad that postings like that one are allowed on a forum for science, especially as the recipients of the W.P. use much worse methods, more indiscriminately, for their own selfish ends. As a total newbie to chems', other than a little dabbling as a schoolboy some 50 odd years ago and messing about of late. Its a whole new world to me that seems fascinating, if approached wisely and sensibly. My interest in chem' came about because of my part time hobby of old engines and motorcycles, I wanted to learn how to 'plate' the metal parts, however there are a lot of chem' formulas, so I am now learning to understand the various mixtures and re-actions. I have found some very interesting information on this forum, it is very easy to understand, mainly because the compounds are usually described by their common names, unlike other sites where they quote a whole string of numbers and distorted letters, a bit like a plate of spahgetti and then leave me to try and decipher the contents. Its a shame my first posting is marred by W.P.comments,but in all truthfulness, it does not help me at all, it is not relevant to the the information I am trying to find,so is really a pointless exercise to try and push their insane opinions in the wrong forum. I hope next time to be more posotive about the contents, kind regards, Bob.
