Welcome to the world of abbrevations and mind forgetting topics.indeed chemistry is a very volatile subject that can lead one to madness if not handled with care so anything that seems difficult should be brought to the board to break down into smaller particles through electrolysis.thank you

The world is gradually changing and we are now in the jet age where technology has taken over everything.still there is no way we can under stand everything so feel free to ask questions

As homosapiens,there is no way we can understand everything in the word because it is not part of our programming from god so when we dont know something,we ask people who do and that is what we are here for.thank you

this class has been made for and only for physics..any body who has a problem in any topic in physics only should bring their problem to the board for answers.please no link should be posted and nothing should be advertised here.if you are not satisfied with the answers you can send an email to me personally or visit my blog in the study page.thank you
