Last Friday, Donald Trump signed an executive order temporarily halting travel from seven Muslim-majority countries. Although several federal judges have stayed deportations of valid visa holders already in the United States, the ban remains in effect nationwide. Much of Trump's presidential campaign relied on strengthening American borders — literally, in the case of his oft-spoken-of wall along the Mexican border — but without immigration and trade, technological progress tends to slow to a crawl. In fact, many inventions Americans use every day wouldn't exist without the countries encompassed in the immigration ban.
The Department of Homeland Security Secretary John Kelly was adamant that the 90-day travel ban is "not a ban on Muslims," but critics have pointed out that all seven countries in question (Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen) are Muslim-majority countries. Each is located in or near the Middle East, an area with a rich history dating back tens of thousands of years. Modern societies owe numerous inventions to Islamic culture, particularly during the Islamic Golden Age, which occurred between the mid-7th and mid-13th centuries. During that time, Muslim culture was at the center of innovations in science, medicine, literature, philosophy, and more. Without these advancements, modern societies would look much different today.
With that in mind, here are seven inventions we still use today from the countries Trump's immigration ban targets.
