 Acquiring knowledge is not bound to a particular person, place, field or thing.  The process has become much easier for any person who knows how to read, living any where in the world, from any religion, with any family background, working in any professional field.  Thanks to all hi-tech contributors, who used their knowledge and talent to bring technology up to this advancement.  All we need to do is to use it properly and positively to take maximum advantage.  Reading ability and a will for betterment is the base of all advancement and progress.
