But ability and opportunity did not always go hand in hand. As an African American and a girl growing up in an era of brutal racism and sexism, Katherine faced daily challenges.

She worked on many of NASA’s biggest projects including the Apollo 11 mission that landed the first men on the moon.

    Yet it is also one of the most puzzling, with an intriguing and sometimes violent history, from the sixth century BCE to the present day. Destroyed by Vesuvius in 79 CE, the ruins of Pompeii offer the best evidence we have of life in the Roman Empire. But the eruptions are only part of the story. In The Fires of Vesuvius, acclaimed historian Mary Beard makes sense of the remains. She explores what kind of town it was--more like Calcutta or the Costa del Sol?--and what it can tell us about ordinary life there. From sex to politics, food to religion, slavery to literacy, Beard offers us the big picture even as she takes us close enough to the past to smell the bad breath and see the intestinal tapeworms of the inhabitants of the lost city. She resurrects the Temple of Isis as a testament to ancient multiculturalism. At the Suburban Baths we go from communal bathing to hygiene to erotica. Recently, Pompeii has been a focus of pleasure and loss: from Pink Floyd's memorable rock concert to Primo Levi's elegy on the victims. But Pompeii still does not give up its secrets quite as easily as it may seem. This book shows us how much more and less there is to Pompeii than a city frozen in time as it went about its business on 24 August 79.
