Al-Khwarizmi Mug
" The Father of Algebra." (780 - 845 C.E.) Abu Abdullah Muhammad bin Musa Al-Khwarizmi was a Persian mathematician and astronomer. He wrote the famous book "Al-Kitab Al-Mukhtasar fi Hisab Al-Jabr Wa'l-Muqabala" ("The Compendious Book on Calculation by Completion and Balancing") in 830. The book offered a systematic and logical approach to solving linear and quadratic equations. This became the premise of algebra. He is also responsible for introducing the Hindu-Arabic numerals to the West, thus becoming the golden standard in global mathematics. He also refined Ptolemy's theories on geography to design the first map of the then "known world", wrote on spacial, time-mechanical devices such as the clock, astrolabe, and sundial, made a table of trigonometric functions, and geometrically interpreted the conic sections.

Great product

They managed to squeeze the (edited down) definition onto the side of the mug in its entirety, so no complaints! Was worried it was going to cut off in the middle of a word or something.
The definition really makes it
Very prompt order fulfillment, and all the messaging was perfect!! Looks great! Thank you!
