Inge Lehmann: Discoverer of the Earth's Inner Core

Danish seismologist Inge Lehmann used seismic signals to study the thousands of earthquakes that occur every year and offer a brief glimpse of what is happening deep inside the Earth. This article profiles a pioneer among women and scientists. It provides an overview of the P-waves and S-waves found in seismic signals and why they are important to our understanding of the Earth's interior, the educational and career struggles Inge Lehmann faced as a woman, and how Lehmann theorized that the Earth's center consisted of both a solid inner core and an outer liquid core.
