  • Mathematics Education in Iran from Ancient to Modern
    Mathematics Education in Iran From Ancient to Modern Yahya Tabesh Sharif University of Technology Shima Salehi Stanford University 1. Introduction Land of Persia was a cradle of science in ancient times and moved to the modern Iran through historical ups and downs. Iran has been a land of prominent, influential figures in science, arts and literature. It is a country whose impact on the global civilization has permeated centuries. Persian scientists contributed to the understanding of nature, medicine, mathematics, and philosophy, and the unparalleled names of Ferdowsi, Rumi, Rhazes, al-Biruni, al-Khwarizmi and Avicenna attest to the fact that Iran has been perpetually a land of science, knowledge and conscience in which cleverness grows and talent develops. There are considerable advances through education and training in various fields of sciences and mathematics in the ancient and medieval eras to the modern and post-modern periods. In this survey, we will present advancements of mathematics and math education in Iran from ancient Persia and the Islamic Golden Age toward modern and post-modern eras, we will have some conclusions and remarks in the epilogue. 2. Ancient: Rise of the Persian Empire The Land of Persia is home to one of the world's oldest civilizations, beginning with its formation in 3200–2800 BC and reaching its pinnacle of its power during the Achaemenid Empire. Founded by Cyrus the Great in 550 BC, the Achaemenid Empire at its greatest extent comprised major portions of the ancient world.

    Sociedade Internacional Para a História da Otorrinolaringologia Robert J. Ruben Introdução As doenças otológicas sempre existiram, mas foram apreciadas de maneiras muito diferentes ao longo do tempo e do local. Como parte de um projeto em andamento, surgiu a questão de qual era o estado da Otologia na época, chamada antiguidade tardia1 de 200 a 600, da Crise do Império Romano no Terceiro Sécu- lo2 (235-284) para, no Oriente, o período do início do Islã (séculos VII-IX), após as conquistas muçulmanas em meados do século VII? Foi realizada uma pesquisa e análise sistemática usando-se 15 (quinze) palavras de pesquisa das traduções originais do material para este período. A antiguidade tardia é considerada como um período de pouco avanço inte- lectual e acadêmico e de agitação social, política e militar. Houve poucos avanços no que consideramos a Europa. Existe a tradição de São Cadoc3, 497 - 580 d.C., do País de Gales, que se acreditava ser capaz de prevenir ou restaurar a perda auditiva. Vários santuários em todo o País de Gales e Bretanha foram dedicados a ele. Estes se encontravam geralmente perto da água, do mar ou de uma fonte. Um exemplo é encontrado na Igreja de São Cadoc, no estuário de Etel, no sul da Bretanha, que é chamado de ‘cama de St. Cadoc’, uma grande estrutura de pedra com uma pequena cavidade em um lado no qual o suplicante aperta a cabeça e pressiona o ouvido afetado contra o leito. Outras intervenções eram derramar água, mel, etc. no ou- vido afetado e oferecer as orações apropriadas4.

  • Pharmacopoeia) in Greeco-Arabian Era : a Historical and Regulatory Perspective Mohd Akhtar Ali1, Hamiduddin2
    International Journal of Human and Health Sciences Vol. 05 No. 04 October’21 Review Article Qarābādhīn (Pharmacopoeia) in Greeco-Arabian era : A Historical and Regulatory Perspective Mohd Akhtar Ali1, Hamiduddin2 Abstract Qarābādhīn can be termed as pharmacopoeia, contains compiled form of compound formulations or recipes. Importance of Qarābādhīn gradually increased and acquired an imperative status. The history of Qarābādhīn starts from Chiron, Aesculapius, Hippocrates, Dioscorides and Galen in Greco-Roman era. Many of early and medieval Islamic and Arab physicians play vital role and immense original contribution in this discipline and authored important and essential Qarābādhīn with systemic and scientific approaches. Although some of them could not reach the present day, many of the manuscripts can be found in various libraries across the world. Since the Arab Caliphates appreciated and patronized the fields of medicine acquired from Greeks and worked for its development, this period also known as “Greco-Arabic era”. In this work the evaluation of Qarābādhīn (particularly written in Arabic or Greek language) was done in historical and regulatory perspective particularly in Greek era and later on in Medieval Islamic era. The findings of the review indicate the importance and regulatory status of Qarābādhīn and provide information about it. It can be helpful to explore Qarābādhīn and related publications of Greek and Medieval Islamic Arabic period, which gives foundations for the present-day pharmacopeias. Since these documents also take into account ethical considerations, its utility in the fields of medicine and medical ethics should be investigated. Keywords: Qarābādhīn, Pharmacopoeia, Greek, Medieval Islamic Medicine, Kūnnāsh, Unani Medicine. International Journal of Human and Health Sciences Vol.
