I have a suspicion that you are neither a 'Professor' or a 'Sir' based on the spelling and grammar of your comment and on the basis of Google research. I'm leaving the comment because you have as much right as anyone to comment here, but I would warn you that some people take (legal) offense to the probable misrepresentation that you are making here. If you were to provide proof of your identity (and email from an academic address for instance) then I will of course make a full apology.
