Elbaz, Stephen Hawkings disabilities work against him rather than for him. Through political correctness out the window for a moment. Have you ever heard the man as he has to speak? Personally, I get bored with the waiting for the next word and sentence to make a complete whole. He has an assistant to help with the translations among other things. This does not take away from his brilliance but rather adds to it that he has been able to make such impressions inspite of his limitations. That he has been able to make such contributions to his field in spite of the handicaps speaks for itself. Do not think for a minute that his colleagues o easy on him for his theories because of his limitations. His theories must still stand to the rigors of scientific method.
