...increasing specialization of the tutorial staffs is due, no doubt, to the fact that unlike the poles of a magnet, like scholars attract like. A Master who is a professor in the sciences will surround himself with young scientists both students and tutors. And once a dominant field is established in a House by the accumulation of several good tutors in that field, applicants for the Houses flock to that House which offers them the best tutorial instruction in their field. As soon as this academic specialization in a House has become a fact it tends to become almost self...
General Electric Co.'s laboratories in Schenectady last week demonstrated (see cut, p. 23) a tiny magnet, about the size of a pellet of buckshot, holding aloft a five pound flatiron. The magnet weighs about one-sixteenth of an ounce. The maximum ratio of lifted load to magnet weight is 1,500 to i, highest in the annals of engineering. Thus General Electric's mighty mite is the most powerful permanent magnet on record...
Before the development of Alnico and other "age-hardening" alloys like it, permanent magnets were all quenched steels. In the newer alloys "magnetic hardness" is obtained by slow, controlled cooling. They provide more magnetic force at lower cost. The increased power of the Alnico magnet shown last week, designed by Physicist Wayne E. (for nothing) McKibben, is due to a steel sheath around it, which efficiently concentrates the magnetic flux very much as an optical lens focuses rays of light...
...SILVER MAGNET-Grant Shepherd -Button...
...Silver Magnet Grant Shepherd does not answer these questions, or explain exactly what finally happened to the mine. Midway through his book he begins to write less about the lost pleasures of Batopilas, and more about long vacations, about sprees, about squabbles with mean-spirited natives, about the petty thievery among workmen, the stupidity of newcomers, the pusillanimity of the Wilson administration, etc. His story becomes a monotonous recital of how the Shepherd brothers put tough customers in their places, of his political opinions and longings for good days long-past. But if its final impression is one of confusion...
