Inge Lehmann

Biography

Inge Lehmann was a Danish seismologist who discovered that Earth has a solid inner core within its liquid outer core. By analyzing seismic waves from earthquakes, she proposed in 1936 that the Earth's core is not a single molten sphere, as previously believed, but has a solid inner part. She lived to 104, making her one of the longest-lived scientists in history, and continued publishing research into her 70s.

英格·莱曼是一位丹麦地震学家，她发现地球在液态外核内有一个固态内核。通过分析地震产生的地震波，她于1936年提出地球的核心不像之前认为的那样是单一的熔融球体，而是有一个固态的内部。她活到了104岁，成为历史上最长寿的科学家之一，70多岁仍在发表研究。
