Some molecules are so small that they contain only one atom. Some are so large that they contain hundreds, thousands, possibly millions of atoms. Although they cannot be seen under the microscope, the giant, complex molecules of proteins are among the most important targets of current research in biological chemistry. Until recent years not much was known about them except that they were very big; that they contained carbon, hydrogen. oxygen, nitrogen and sometimes sulphur and phosphorus; that in such animal processes as digestion they were broken down by protein-wreckers called enzymes and that they were composed of polypeptide...
Last week Harvey O'Connor (Mellon's Millions) offered The Guggenheims, a well-documented unraveling of the complex history of the Guggenheim mining fortune that made U. S. novelists' omission seem even more remarkable. Like the Buddenbrooks and Forsytes, the Guggenheim family began with sober business men, many of whose latest descendants forsook business for the arts, involved complicated family relationships, fierce squabbles. But unlike their counterparts in European fiction, the Guggenheims pictured by Harvey O'Connor have operated on a scale calculated to dazzle the most imaginative novelists...
Modern radium extraction is a highly complex process, started with big ovens, reaction vats, filter presses and decanters, working down to delicately controlled processes in vessels hardly larger than thimbles. When the concentration of radium is as high as 1%, trained chemists take over the job, wearing protective gloves and clothing and working intermittently to avoid injury from the potent gamma, beta and alpha rays. The final product is not pure radium but 90 to 94% pure radium bromide...
...complex intrigue behind the scenes, while sergeants-at-arms were struggling on the Chamber stage with irate but inconsequential legislators, the efforts of the Communists to get something Moscow really wanted in return for their support penetrated via new French Premier Chau-temps even as far as London. His Majesty's Government were extremely near the point of extending "belligerent rights" to the Spanish Rightists last week (see p. 24), when Downing Street received frantic word from the Quai d'Orsay that Premier Chautemps, in order to get his Cabinet over its first rocks in the Chamber, must...
...rapidly passed about from hand to hand by the inhabitants of each conforming world. But if we are to reject this false metal we must be prepared each one of us to mint our own--we must be prepared to make our own judgments of the most intricate and complex situations. To do this with any degree of success requires, indeed, "a rich background and a disciplined insight...
