Camels, ruminant mammals of the family Camelidae, are well adapted to desert life, as they can live for several days without drinking and their broad, flat, two-toed feet do not sink in the sand. There are two species of true camel, the single-humped Arabian camel, a domesticated animal used in Arabia and N Africa, and the two-humped Bactrian camel of central Asia. The humps, fat stores that provide energy and water when metabolized, also aid in desert survival. How fast can a camel run?

During this coup d'Ã©tat, General Bonaparte overthrew the weakened government of the Directory, replaced it with the Consulate, and secured his own election as First Consul. This marked a major turning point in the history of the French Revolution, replacing earlier experiments in democracy with a more stable but autocratic rule. The coup was instigated by Emmanuel SieyÃ¨s as an attempt to prevent a return to Jacobinism, but Bonaparte soon seized control. What was the "coup within a coup"?

Weyl, a German physicist and mathematician, was one of the first scientists to combine general relativity with the laws of electromagnetism. His work on the topics of space, time, matter, philosophy, logic, and symmetry has earned him consideration as one of the most influential 20th century mathematicians. Early in his career, Weyl worked alongside Albert Einstein, whose work left a lasting impression on the former. In 1918, what prediction did Weyl make concerning the future of mathematics?
