The Command of Light
Henry Rowland (1848-1901) was one of the most important figures in the founding of modern physics in the U.S. A principal founder and first pres. of the Amer. Physical Soc., he is best known for his invention of the concave spectral grating for which he won a gold medal and grand prize at the 1890 Paris Exposition. A grad. of Rensselaer Polytechnic Inst. in civil engineering, Rowland was prof. of physics at Johns Hopkins Univ., where he had the principal part in forming the first school of Amer. physicists to be professionally trained in the U.S. In this vol., Sweetnam, using Rowland's papers and those of his colleagues and students, has written the first scholarly exposition of Rowland's work.

The Last Caesar
As Emperor Nero casts his madness over Rome, a loyal soldier is caught in a conspiracy that threatens the empire in this historical epic. Rome, 68 AD: The tyrant emperor Nero has no heir, and whispers of rebellion are spreading fast. As Rome faces the possibility of becoming a republic once more, the ambitions of a few are about to bring untold corruption, chaos, and bloodshed. Aulus Caecina Severus, hero of the campaign against Boudica, has become part of a conspiracy to overthrow Caesar’s dynasty. But is it really all for the good of Rome? The boundary between service and self-preservation is far from clear, and navigating this dangerous path requires all Severus’ skills: as a cunning soldier and, increasingly, a deft politician. As the Year of the Four Emperors unfolds, the mighty Roman empire will be plunged into anarchy and civil war . . .
The Sword and the Throne
As Rome enters the Year of the Four Emperors, a soldier marches into the crucible of battle to meet his uncertain fate in the sequel to The Last Caesar. Rome, 69 AD: In the bloody contest for control of Rome, Aulus Caecina Severus has thrown in his lot with the hedonistic military commander Vitellius. Now he must prepare his legions for a grueling march over the Alps. Severus leads his army against barbarian rebellions and the tough mountain passes in his race to reach Italy before his rival Valens. With the Po valley almost in sight, news comes that Emperor Galba has been killed in a coup, and that Otho has been declared Emperor by the Praetorians. But there is no turning back for Severus: the Rhine legions want their man on the throne, leading Severus down a dark path. Politics is the new battleground, and Severus needs the help of his wife Salonina and his freedman Totavalas if he wants to survive. And as a new power emerges in the east, Severus must decide where his true loyalty lies . . .
