equals

There was a short piece on Today, today about design once again holding up the excellent tube map as a design classic due to the way it displays a complex system in a simple and easily usable way. However it was the invention of the equal sign “=” that caught my ear. How lucky we are that Robert Record did not patent that. It's hard to imagine a world without “=”. We could not have “==” without “=”. Makes me wonder who invented “!” as not and gave us “!=”.
