Pesia was a cradle of science in ancient times. Persian scientists contributed to the current understanding of nature, medicine, mathematics, and philosophy. Persians made important contributions to algebra and chemistry, invented the wind-power machine, and the first distillation of alcohol. Trying to revive the golden time of Persian science, Iran’s scientists cautiously reach out to the world. Many individual Iranian scientists, along with the Iranian Academy of Medical Sciences and Academy of Sciences of Iran, are involved in this revival. Iran is an example of a country that has made considerable advances through education and training, despite international sanctions in almost all aspects of research during the past 30 years. Iran’s university population swelled from 100,000 in 1979 to 2 million in 2006. Seventy percent of its science and engineering students are women. Science in Persia evolved in two main phases separated by the arrival and widespread adoption of Islam in the region. Many of the today’s concepts in Science including Helio-Centric model of solar system, finite speed of light, and gravity were first proposed by Persian scientists.
