## History of Mathematical Symbols

This is a great resource:  a brief history of many mathematical symbols.

Ever wonder where the symbol for $\pi$ comes from?  Or why we use ‘%’ for percent?  Or who first used $\infty$ to first represent infinity?

There’s all that, and much more!  Although, I would like to know more about the bar used to represent repeating decimals.
