Serageldin could not attend the inauguration of the conference on Unknown Aspects Of Arab Contributions To The History Of Science. He expressed deep regret that urgent duties required his attendance in Cairo. He specifically mentioned that this was a topic of particular interest for which he had prepared with a disquisition on the nature of evolving scientific paradigms and the contributions of Arabs specifically and Muslims generally to the structure of scientific thought in the Middle Ages. However, it was not possible to be there, much to his regret.
