02 Schooling and Education
It is
commonly believed in United States that school is where people go to get an education. Nevertheless, it has been said that today children interrupt their education to go to school. The distinction between schooling and education implied by this remark is important.
Education is much more open-ended and all-inclusive than schooling. Education knows no bounds. It can take place anywhere, whether in the shower or in the job, whether in a kitchen or on a
tractor. It includes both the formal learning that takes place in schools and the whole
universe of
informal learning. The agents of education can range from a revered grandparent to the people debating politics on the radio, from a child to a
distinguishedscientist. Whereas schooling has a certain predictability, education quite often produces surprises. A chance conversation with a stranger may lead a person to discover how little is known of other religions. People are engaged in education from
infancy on. Education, then, is a very broad, inclusive term. It is a
lifelong process, a process that starts long before the start of school, and one that should be an integral part of one's entire life.
Schooling, on the other hand, is a
specific, formalized process, whose general pattern varies little from one
setting to the next. Throughout a country, children arrive at school at
approximately the same time, take assigned seats, are taught by an adult, use similar textbooks, do homework, take exams, and so on. The slices of reality that are to be
learned, whether they are the alphabet or an understanding of the working of government, have usually been
limited by the boundaries of the subject being taught. For example, high school students know that there not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. There are definite conditions
surrounding the formalized process of schooling.
03 The Definition of "Price"
Prices determine how resources are to be used. They are also the means by which products and services that are in
limited supply are rationed among buyers. The price system of the United States is a complex
networkcomposed of the prices of all the products bought and sold in the economy as well as those of a
myriad of services, including labor, professional, transportation, and public-utility services. The interrelationships of all these prices make up the "system" of prices. The price of any particular product or service is linked to a broad, complicated system of prices in which everything seems to depend more or less upon everything else.
If one were to ask a group of randomly selected individuals to
define "price", many would reply that price is an amount of money paid by the buyer to the
seller of a product or service or, in other words that price is the money values of a product or service as agreed upon in a market transaction. This
definition is, of course, valid as far as it goes. For a complete understanding of a price in any particular transaction, much more than the amount of money involved must be known. Both the buyer and the
seller should be familiar with not only the money amount, but with the amount and quality of the product or service to be exchanged, the time and place at which the exchange will take place and payment will be made, the form of money to be used, the credit terms and discounts that apply to the transaction, guarantees on the product or service,
delivery terms, return privileges, and other factors. In other words, both buyer and
seller should be fully aware of all the factors that
comprise the total "package" being exchanged for the asked-for amount of money in order that they may evaluate a given price.
04 Electricity
The modern age is an age of
electricity. People are so used to electric lights, radio, televisions, and telephones that it is hard to imagine what life would be like without them. When there is a power failure, people grope about in flickering candlelight, cars hesitate in the streets because there are no traffic lights to guide them, and food spoils in silent refrigerators.
Yet, people began to understand how
electricity works only a little more than two centuries ago. Nature has
apparently been experimenting in this field for million of years. Scientists are discovering more and more that the living world may hold many interesting secrets of
electricity that could benefit humanity.
All living cell send out tiny pulses of
electricity. As the heart beats, it sends out pulses of record; they form an electrocardiogram, which a doctor can study to determine how well the heart is working. The brain, too, sends out brain waves of
electricity, which can be recorded in an electroencephalogram. The electric currents generated by most living cells are extremely small ? often so small that
sensitive instruments are needed to record them. But in some animals, certain muscle cells have become so specialized as
electrical generators that they do not work as muscle cells at all. When large numbers of these cell are linked together, the effects can be
astonishing.
The electric eel is an amazing
storagebattery. It can seed a jolt of as much as eight hundred volts of
electricity through the water in which it live. ( An electric house current is only one hundred twenty volts.) As many as four-fifths of all the cells in the electric eel's body are specialized for generating
electricity, and the strength of the shock it can deliver corresponds
roughly to length of its body.
