This boundary is known as the Bullen discontinuity, or sometimes as the Lehmann discontinuity. A few years later, in 1940, it was hypothesized that this inner core was made of solid iron; its rigidity was confirmed in 1971.

ROMAN: As a young woman, OâConnor went to the Iowa Writers Workshop, to the exclusive Yaddo artistâs colony in Saratoga Springs, and then to New York City and Connecticut, writing all the way. Then, at the age of 25, she was forced to return home because, like her father before her, she was dying of lupus.ince OâConnorâs death, more than 50 books have been written about her, one of them by Ralph Wood of Baylor University.
