...from one orbit to another. Such excited atoms, according to quantum theory, should have energy levels differing from each other by precise amounts. Drs. Menzel & Boyce expressed a number of these energy levels mathematically. Then (by extrapolation of the 43-year-old Rydberg method) they mathematically expressed the light-wave frequencies represented by the five mysterious spectrum lines. Last, they brought the two sets of mathematical expressions together. In three cases the correspondence was close enough to remind them of keys fitting into locks, to enable them to say that most of "coronium" is oxygen...

Even a green safety lamp cannot be used; all work is done by the touch system...

They wanted to see the Gran Sasso (''Big Rock") as he trained for his ''fight" in Rome with Paulino Uzcudun. Bustling importantly, Carnera's father tried to wave the crowds away. "Let Primo alone!" he shrilled. But the crowds hung on, grateful for an occasional glimpse of the monstrous, slow-witted champion as he trotted out with his trainers for roadwork, or shambled into a backyard garage through a door topped by Juvenal's maxim. MENS SANA...
...happen to Marc in the post-War maelstrom, but her cool head warns her to keep her hands off. They are very poor, and Annette steadfastly refuses to take money from her half-sister Sylvie. who as the shrewd mistress of a millionaire is riding high on the tidal wave. When Marc finishes school, he and his mother part-she to go to Rumania as companion in a rich family, he to sink or swim for himself in Paris.
