When people think of dinosaurs with feathers, they typically think of winged dinosaurs, such as the four-winged Microraptor. However, many dinosaurs that didn’t have wings also had feathers on their bodies. For instance, research indicates that the wingless, speedy Ornithomimus likely had feathers.

Women like Minnie McNeal Kenny made important early contributions to the history of US cryptology, a field concerned with secure data communication and storage. Kenny worked for the National Security Agency (NSA) and received the NSA’s two highest awards. She also held administrative positions at the National Cryptologic School. In this way, Kenny and others like her helped make it possible for more women—such as Anna Lysyanskaya, who currently works in and teaches digital cryptography—to enter the field of cryptology.

Mauricio Drelichman and Hans-Joachim Voth’s research into the debt defaults of Philip II (who ruled an empire including Spain and Northern Catalonia from 1556 to 1598) relates to other work on European early modern state finance, including John Brewer’s research on taxation and warfare. But Drelichman and Voth’s unique contribution to the field is their reconstruction of the earliest extant set of annual fiscal records for any sovereign state, demonstrating in turn that Philip’s defaults were caused by short-term cash shortages, not long-term unsustainable debts.

The following text is from María Amparo Ruiz de Burton’s 1885 novel The Squatter and the Don.

Don Mariano Alamar was silently walking up and down the front piazza of his house at the rancho; his hands listlessly clasped behind and his head slightly bent forward in deep thought. He had pushed away to one side the many arm-chairs and wicker rockers with which the piazza was furnished. He wanted a long space to walk. That his meditations were far from agreeable, could easily be seen by the compressed lips, slight frown, and sad gaze of his mild and beautiful blue eyes.

The following text is from Julia Alvarez’s 2000 novel In the Name of Salomé. The narrator and her sister, daughters of a famous poet, are being tutored by Alejandro Román.

Our tutor, Alejandro Román, would bring his younger brother, Miguel, to class one day. By now I was eighteen and had turned down enough suitors to acquire a reputation of being aloof. Miguel also was studying poetry, and he had heard from his brother that the Ureña girls were none other than the daughters of Nicolás Ureña, and they were smart as clockwork. Miguel was hoping not only to meet us but to make the acquaintance of the poet himself at Mamá’s house.
