### About This Quote

Unsourced

**Source:**"Why Is 'X' the Unknown?" TED2012. Feb. 2012. Conference Presentation.

**Additional Information:**This quote from Terry Moore, director of the Radius Foundation, compares the Arabic language to mathematics. Like the "language" of mathematics, Arabic is a very logical language and this has to do with the ancient Arabic world being the origin of mathematical disciplines such as algebra, says Moore. This connection between the Arabic language and mathematics is also related to why we use the letter "x" to represent the unknown in equations, as Moore explains in the 2012 TED Talk that is the source of this quote.
