The Language of Music A painter hangs his or her finished pictures on a wall, and everyone can see it. A composer writes a work, but no one can hear it until it is performed. Professional singers and players have great responsibilities, for the composer is utterly dependent on them. A student of music needs as long and as arduous a training to become a performer as a medical...

Choosing An Occupation Hodeslea, Eastbourne, November 5, 1892 Dear Sir, I am very sorry that the pressure of other occupations has prevented me from sending an earlier reply to your letter. In my opinion a man’s first duty is to find a way(1) of supporting himself, thereby relieving other people of(2) the necessity of supporting him. Moreover, the learning to do work o...
The Rainy Day The day is cold,and dark,and dreary; It rains,and the wind is never weary; The vine still clings to the moldering wall, But at every gust the dead leaves fall, And the day is dark and dreary. My life is cold and dark and dreary; It rains and the wind is never weary; My though still cling to the moldering past, But the hopes of youth fall thick in the blast, And...

Oil and Water To understand the emulsifying process, we must first accept the scientific principle that oil and water do not naturally mix. Quite literally, they find each other’s presence repulsive. A good illustration of this aversion is homemade oil and vinegar salad dressing.When you shake or beat your salad dressing, you do more than disperse the oil throughout th...
Suburbanization If by “suburb” is meant an urban margin that grows more rapidly than its already developed interior, the process of suburbanization began during the emergence of the industrial city in the second quarter of the nineteenth century. Before that period the city was a small highly compact cluster in which people moved about on foot and goods were con...
Nitinol Nitinol is one of the most extraordinary metals to be discovered this century: A simple alloy of nickel and titanium, nitinol has some perplexing properties. A metal with a memory, it can be made to remember any shape into which it is fashioned, returning to that shape whenever it is heated. For example, a piece of nitinol wire bent to form a circle that is then heat...
Chimpanzee The most striking single fact about chimpanzees is the flexibility of their social life, the lack of any rigid form of organization. It represents about as far a departure from the baboon type of organization as one can find among the higher primates, and serves to emphasize the great variety of primate adaptations. Chimpanzees are more human than baboons, or rath...
Modern American Universities Before the 1850’s, the United States had a number of small colleges,most of them dating from colonial days. They were small, church connected institutions whose primary concern was to shape the moral character of their students. Throughout Europe, institutions of higher learning had developed, bearing the ancient nameof university. In Germa...
Statistics There were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of governmental units (state and statistics come from the same Latin root status) and a gentlemanly gambling father who relied on mathematics to increase his skill at playing the odds in games of chance. ...
The Revolution in American Higher Education To produce the upheaval in the United States that changed and modernized the domain of higher education from the mid 1860’s to the mid 1880’s, three primary causes interacted. The emergence of a half dozen leaders in education provided the personal force that was needed. Moreover, an outcry for a fresher, more practical...
Skyscrapers and Environment In the late 1960’s,many people in North America turned their attention to environmental problems,and new steel-and-glass skyscrapers were widely criticized.Ecologists pointed out that a cluster of tall buildings in a city often overburdens public transportation and parking lot capacities. Skyscrapers are also lavish consumers, and wasters, o...
Sleep Sleep is part of a person’s daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you first drift off into slumber, your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing well slow and become qui...
The Origin of Sports When did sport begin? If sport is, in essence, play, the claim might be made that sport is much older than humankind, for, as we all have observed, the beasts play. Dogs and cats wrestle and play ball games.Fishes and birds dance.The apes have simple, pleasurable games. Frolicking infants, school children playing tag, and adult arm wrestlers are emonstra...

Growth That Starts From Thinking It seems to me a very difficult thing to put into words the beliefs we hold and what they make you do in your life. I think I was fortunate because I grew up in a family where there was a very deep religious feeling. I don’t think it was spoken of a great deal. It was more or less taken for granted that everybody held certain beliefs and nee...
A Lesson Learned at Midnight By James Q. DuPont Ever since one midnight, in nineteen hundred and nine, when I first heard my mother crying, I have been groping for beliefs to help me through the rough going and confusions of life. My dad’s voice was low and troubled as he tried to comfort Mother. And in their anguish, they both forgot the nearness of my bedroom. And so, I ov...
Police and Communities Few institutions are more important to an urban community than its police, yet there are few subjects historians know so little about. Most of the early academic interests developed among political scientists and sociologists, who usually examined their own contemporary problems with only a nod toward the past. Even the public seemed concerned only dur...
