If a mother pushes her small son in a swing, giving only a light force each time he returns, eventually he will be swinging quite high. The child can do this for himself by using his legs to increase the motion, but both the mother’s push and the child’s leg movements must occur at the proper moment, or the extent of the swing will not increase. In physics, increasing the swing is increasing the amplitude; the length of the rope on the swing determines its natural oscillation period. This ability of an object to move periodically or to vibrate when stimulated by a force operating in its natural period is called resonance. Resonance is observed many times without consciously thinking about it; for example, one may find an annoying vibration or shimmy in an automobile, caused by a loose engine mount vibrating with increasing amplitude because of an out-of-round tire. The bulge on the tire slaps the pavement with each revolution; at the natural resonance point of the engine mount, it will begin to vibrate. Such vibrations can result in considerable damage if allowed to persist. Another destructive example of resonance is the shattering of a crystal goblet by the production of a musical tone at the natural resonant point of goblet. The energy of the sound waves causes vibration in the glass; as its amplitude increases, the motion in the glass exceeds the elasticity of the goblet, and it shatters. An instrument called a tachometer makes use of the principle of resonance. It consists of many tiny bars, loosely fastened together and arranged so that each bar can slide independently of the others. Movement of the bars causes changes in a dial. When placed next to a rotating motor or engine, the tachometer picks up slight vibrations which are transferred to the resonant bars. These bars begin to move, and the resulting dial may be read to find the revolutions per minute of the motor very quickly.

Since the first brain scanner was constructed several years ago, computed tomography or computed medical imagery, has become fairly widely used. Its rapid acceptance is due to the fact that it has overcome several of the drawbacks of conventional X-ray technology. To begin with, conventional two-dimensional X-ray pictures cannot show all of the information contained in a three-dimensional object. Things at different depths are super imposed, causing confusion to the viewer. Computed tomography can give three-dimensional information. The computer is able to reconstruct pictures of the body’s interior by measuring the varying intensities of X-ray beams passing through sections of the body from hundreds of different angles. Such pictures are based on series of thin “slices“. In addition, conventional X-ray generally differentiates only between bone and air, as in the chest and lungs. They cannot distinguish soft tissues or variations in tissues. The liver and pancreas are not discernible at all, and certain other organs max only be rendered visible through the use of radio paque dye. Since computed tomography is much more sensitive, the soft tissues of the kidneys or the liver can be seen and clearly differentiated. This technique can also accurately measure different degrees of X-ray absorption, facilitating the study of the nature of tissue. A third problem with conventional X-ray methods is their inability to measure quantitatively the separate densities of the individual substances through which the X-ray has passed. Only the mean absorption of all the tissues is recorded. This is not a problem with computed tomography. It can accurately locate a tumor and subsequently monitor the progress of radiation treatment, so that in addition to its diagnostic capabilities, it can play a significant role in therapy.

When imaginative men turn their eyes towards space and wonder whether life exists in any part of it, they may cheer themselves by remembering that life need not resemble closely the life that exists on Earth. Mars looks like the only planet where life like ours could exist, and even this is doubtful. But there may be other kinds of life based on other kinds of chemistry and they may multiply on Venus or Jupiter. At least we cannot prove at present that they do not. Even more interesting is the possibility that life on their planets may be in a more advanced stage of evolution. Present-day man is in a peculiar and probably temporary stage. His individual units retain a strong sense of personality. They are, in fact, still capable under favorable circumstances of leading individual lives. But man’s societies are already sufficiently developed to have enormously more power and effectiveness than the individuals have. It is not likely that this transitional situation will continue very tong on the evolutionary time scale. Fifty thousand years from now man’s societies may have become so close-knit that the individuals retain no sense of separate personality. Then little distinction will remain between the organic parts of the multiple organism and the inorganic parts(machines)that have been constructed by it. A million years further on man and his machines may have merged as closely as the muscles of the human body and the nerve cells that set them in motion. The explorers of space should be prepared for some such situation. If they arrive on a foreign planet that has reached an advanced stage(and this is by no means impossible), they may find it being inhabited by a single large organism composed of many closely cooperating units. The units may be “secondary“—machines created millions of years ago by a previous form of life and given the will and ability to survive and reproduce. They may be built entirely of metals and other durable materials, if this is the case, they may be much more tolerant of their environment multiplying under conditions that would destroy immediately any organism made of carbon compound and dependent on the familiar carbon cycle. Such creatures might be relics of a past age, many millions of years ago, when their planet was favorable to the origin of life or they might be immigrants from a favored planet.

Before the 1870’s, trained nurses were virtually unknown in the United States. Hospital nursing was an unskilled occupation, taken up by women of the lower classes, some of whom were from the charity house. The movement for reform originated not with doctors, but among upper-class women, who had taken on the role of guardians of a new hygienic order. Though some doctors approved of the women’s desire to establish a nurses’ training school, which would attract the daughters of the middle class, other medical men were opposed. Plainly threatened by the prospect, they objected that educated nurses would not do as they were told. When resisted, as they were at Bellevue in efforts to install trained nurses on the maternity wards, they went over the heads of the doctors to men of their own class of greater power and authority. Professional nursing, in short, emerged neither from medical discoveries nor from a program of hospital reform initiated by physicians; outsiders saw the need first. Questions 21-25 are based on the passage you have just heard. 21. According to the passage, what could best describe nurses in the United States in the 1850’s? 22. Who is the first advocate of nursing training in the United States? 23. According to the passage, why some doctors objected to the establishment of nursing schools? 24. Which of the following is discussed in the passage? 25. What can be inferred from the passage? Poor, untrained women. Young medical students. Wives of military officers. Middle-class men and women.
