Western civilization has made invaluable contributions to the development of the sciences. However, so have numerous other cultures. Unfortunately, Westerners have long been credited with discoveries made many centuries before by Islamic scholars. Thus, many of the basic sciences were invented by non-Europeans. For instance, George Sarton states that modern Western medicine did not originate from Europe and that it actually arose from the (Islamic) orient.

The data in this section concerning dates, names and topics of Western advances has been derived from three main sources: World Book Encyclopedia, Encyclopaedia Britannica and Isaac Asimov's 700 page book, Chronology of Science and Discovery. Supportive data for the accomplishments of Islamic scholars is derived from the miscellaneous references listed in the bibliography of this book.
