**Abstract: **
In 1789, the otherwise obscure Slovenian Major Jurij Vega announced
that he had calculated pi to 140 decimal places, breaking De Lagny's
record of 127 decimal places that had stood for 72 years. We will look
at how and why Vega performed his famous calculation, and what makes
it important.

This talk will be accessible to undergraduates.
