Why does the western world, who are proudly descended from the Romans, use the Arabic Numeral system instead of the Roman one? You can find out why and when that change happened in this short and simple animated documentary.

The dead famous come to life in this animated history show based on the popular “Corpse Talk” graphic novel series by Adam and Lisa Murphy. Ibn Al Haytham’s stopping by to talk about his life and times as a scientist and philosopher, back at the turn of the last millennium. Born in 965AD during the Islamic Golden Age, Al Haytham spent ten years under house arrest but made the most of his time, writing over 100 books and…Well, let’s let him tell you.

The 7th to the 13th century was the golden age of Muslim learning. In mathematics they contributed and invented the present arithmetical decimal system and the fundamental operations connected with it: addition, subtraction, multiplication, division, exponentiation, and extracting the root. They also introduced the ‘zero’ concept to the world. Some of the famous mathematicians of Islam are: AL-KHWARIZMI (780 – 850 CE) Muhammad Ibn Musa Al-Khwarizmi, the father of algebra, was a mathematician and astronomer. It is generally assumed that Al-Khwarizmi was born around 780 CE in the town of Kath in the oasis of Khorzen. Kath is now buried in the sand. Al-Khwarizmi was summoned to Baghdad by Al-Mamun and appointed court astronomer. From the title of his work, Hisab Al-Jabr wal Mugabalah (Book of Calculations, Restoration and Reduction), Algebra (Al-Jabr) derived its name. AL-KINDI (801-873 CE) Abu Yusuf Yaqub Ibn Ishaq Al-Kindi, was born around 801 CE in Kufa during the governership of his father. The surname indicates ancestry in the royal tribe of Kindah of Yemenite origin. To his people he became known as Faylasuf Al-Arab (the philosopher of the Arabs) the first one in Islam. Among his contributions to arithmetic, Al-Kindi wrote eleven texts on numbers and numerical analysis. AL-KARAJI Abu Bakr ibn Hussein was born in Kharkh, a suburb of Baghdad. His works covered arithmetic, algebra and geometry. His book ‘Al-Kafi fi Al-Hisab’ (Essentials of Arithmetic) covers the rules of computation. His second book, ‘Al- Fakhri’ derived its name from Al- Kharki’s friend, the Grand Vizier of Baghdad. Al-BATTANI (850-929 CE) Muhammad Ibn Jabir Ibn Sinan Abu Abdullah, the father of trigonometry, was born in Battan, Mesopotamia and died in Damascus in 929 CE. An Arab prince and governor of Syria, he is considered to be the greatest Muslim astronomer and mathematician. Al-Battani raised trigonometry to higher levels and computed the first table of cotangents. AL-BIRUNI (973-1050 CE) Al-Biruni was among those who laid the foundation for modern trigonometry. He was a philosopher, geographer, astronomer, physicist and mathematician. Six hundred years before Galileo, Al-Biruni discussed the theory of the earth rotating about its own axis. Al-Biruni carried out geodesic measurements and determined the earth’s circumference in a most ingenious way. With the aid of mathematics, he enabled the direction of the Qibla to be determined from anywhere in the world. In the domain of trigonometry, the theory of the functions; sine, cosine, and tangent was developed by Muslim scholars of the tenth century. Muslim scholars worked diligently in the development of plane and spherical trigonometry. The, trigonometry of Muslims is based on Ptolemy’s theorem but is superior in two important respects: it employs the sine where Ptolemy used the chord and is in algebraic instead of geometric form.

And despite the remarkable complexity of these designs, they can be created with just a compass to draw circles and a ruler to make lines within them. Eric Broug covers the basics of geometric Islamic design. Lesson by Eric Broug, animation by TED-Ed.

In 2011, The Metropolitan Museum of Art opened the New Galleries for the Art of the Arab Lands, Turkey, Iran, Central Asia, and Later South Asia, which house the Museum's renowned collection of Islamic art. A vital part of the installation was the Patti Cadby Birch Court, a Moroccan court built by a team of experts—from curators and historians to designers and craftsmen—over many months. Complementing the works on view, which span the past fourteen hundred years, the Moroccan Court provides an experience of space and architecture while demonstrating artistic traditions that still thrive in the Islamic world. This video documents a marvelous journey from Fez to New York, and the creation of a twenty-first-century court using traditional fifteenth-century methods. The court was made possible by the Patti and Everett B. Birch Foundation.
