No woman has yet won one of the three top mathematics awards–the Fields, the Abel, or the Wolf. It’s part of what’s often called the math gender gap, which in the United States starts early—at least twice as many boys as girls score in the 99th percentile on state-level math assessment tests.

Asad Madni and the Life-Saving Sensor

In 1992, Asad M. Madni sat at the helm of BEI Sensors and Controls, overseeing a product line that included a variety of sensor and inertial-navigation devices, but its customers were less varied—mainly, the aerospace and defense electronics industries.

And he had a problem.

The Cold War had ended, crashing the U.S. defense industry. And business wasn’t going to come back anytime soon. BEI needed to identify and capture new customers—and quickly.
