How did Muslims in Medieval times contribute to our life today?

Answer 1

Muslims lived in great numbers in Spain from about the year 711 AD, when they invaded, to the year 1492, when they were expelled. During that time, they made a series of important contributions in mathematics and science that deeply influenced European civilization to this day. Many of the words in English that begin with "al-" are derived from Arabic, and the influence can actually be traced by looking at these words.

Alcove is one. It exists in English because of contributions of Muslims to architecture.

Alchemy is another. It was the study from which modern chemistry is derived, and in fact the later word is derived from the earlier. It exists in English because of contributions by Muslims to chemistry. Some chemicals have names derived from Arabic. Alcohol came from an Arabic word meaning demon.

Algebra is another word, resulting from Muslim contributions in mathematics, and, in fact, algebra was invented by Muslims.

The number system we use, which replaced the old Roman Numerals, is called the Arabic number system. If you try multiplying CXCVII times XIX, you might just be thankful for contributions of Muslims every time you do math after that.

Most of the common names we have for stars are Arabic, and exist in our language because of contributions in astronomy and navigation by Muslims.

Nearly all the works that came from ancient Greek and were available to Western medieval scholars were translate into Latin from Arabic. The Almagest of Ptolemy got the "Al-" in its name because of this.

These are examples from one country during one period of history. The time and place are very important for the answer, but there were times and other places where Muslims contributed to European culture in important ways.
