Simple Magic Square - History

History

Magic squares were known to Chinese mathematicians as early as 650 BCE, and to Arab mathematicians possibly as early as the 7th century CE, when the Arabs conquered northwestern parts of the Indian subcontinent and learned Indian mathematics and astronomy, including other aspects of combinatorial mathematics. The first magic squares of order 5 and 6 appear in an encyclopedia from Baghdad circa 983 CE, the Encyclopedia of the Brethren of Purity (Rasa'il Ihkwan al-Safa); simpler magic squares were known to several earlier Arab mathematicians. Some of these squares were later used in conjunction with magic letters, as in (Shams Al-ma'arif), to assist Arab illusionists and magicians.

Famous quotes containing the word history:

    Social history might be defined negatively as the history of a people with the politics left out.
    —G.M. (George Macaulay)

    The greatest horrors in the history of mankind are not due to the ambition of the Napoleons or the vengeance of the Agamemnons, but to the doctrinaire philosophers. The theories of the sentimentalist Rousseau inspired the integrity of the passionless Robespierre. The cold-blooded calculations of Karl Marx led to the judicial and business-like operations of the Cheka.
    Aleister Crowley (1875–1947)

    The history of our era is the nauseating and repulsive history of the crucifixion of the procreative body for the glorification of the spirit.
    —D.H. (David Herbert)
