One of the styles that is particular to Isaac Asimov is that he used to give description in his works mentioning the historical contexts when the concept was being come into force. He used to go to that stage when the scientific concept he was describing was in its simplest form. When you read his work, you will find that when he was mentioning about a scientist, he gave his birth dates also. It is not only birth date; he also mentioned the nationalities and the date of the death of the person. The other unique feature about his work is that he also included the pronunciation guide also of the technical terms that he used in his work. The best example of this kind of work is Understanding Physics and Guide to Science where he followed al the rules that he set for himself.
