Martha had been working for Miller Laboratories for two years, but she was not happy there. Nothing significant had happened in the way of promotions or salary increases. Martha felt that her supervisor, a younger and less experienced person than she, did not like her. In fact, the supervisor often said unpleasant things to her. One day, while talking with her friend Maria, she mentioned how discouraged she was. Maria gave her the name of a cousin of hers who was director of Human Resources Department for a large chemical company. Martha called him the next day and set up an interview on her lunch hour. During the interview, Mr. Petri said, "You're just the kind of person we need here. You're being wasted in your other job. Give me a call in a day or two. I'm sure we can find a place for you in our organization." Martha was so happy she almost danced out of the building. That afternoon, Ruth Kenny, her supervisor, saw that Martha had come in ten minutes late from her lunch hour and she said, "Oh, so you finally decided to come back to work today?" This was . She could not take another insult. Besides, Mr. Petri was right: she was being wasted in this job. "Look," she said angrily, "if you don't like the way I work, I don't need to stay here. I'll go where I'm appreciated! Good-bye!" She took up her things and stormed out of the office. That night she called Maria and told her what had happened and then asked Maria, "What do you think?" "Well," said Maria carefully, "are you sure about the other job?" "Well, not exactly, but..." Maria continued, "Will you be able to get a recommendation from Mrs. Kenny if you need one?" "A recommendation?...from Mrs. Kenny?" hesitated Martha, in a worried tone. "Martha, I hope you didn't burn your bridges." Maria said. "I think I would have handled it differently."

Probably no other musical instrument is as popular as the guitar around the world. Musicians use the guitar for almost all kinds of music. Country and western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. And rock and roll music would almost be impossible without this instrument.

Music experts do not agree about where the guitar was first played. Most agree it is ancient. Some experts say an instrument very much like a guitar was played in Egypt more than 1,000 years ago. Most experts say that the ancestor of the modern guitar was brought to Spain from Persia sometime in the 12thcentury. The guitar continued to develop in Spain. In the 1700s it became similar to the instrument we know today.

Many famous musicians played the instrument. The famous Italian violins Niccole Paganism played and wrote music for the guitar in the early 1800s. Franz Schubert used the guitar to write some of his famous works. In modern times Spanish guitarist Andres Segovia helped make the instrument extremely popular.

In the 1930s, Les Paul began experimenting to make an electric guitar. He invented the solid-bodied electric guitar in 1946. The Gibson Guitar Company began producing its famous Les Paul Guitar in 1952. It became a powerful influence on popular music. The instrument has the same shape and the same six strings as the traditional guitar, but it sounds very different. Les Paul produced a series of extremely popular recordings that introduced the public to this music. Listen to this Les Paul recording. It was the fifth most popular song in the United States in 1952. It is called "Meet Mister Callaghan." What are the answers to this following set of questions: 1. What muscial instrument is being talked about here?
2. What kind of music you usually hear a guitar?

An organic compound is virtually any chemical compound that contains carbon, although a consensus definition remains elusive and likely arbitrary. Organic compounds are rare terrestrially, but of central importance because all known life is based on organic compounds. The most basic petrochemicals are considered the building blocks of organic chemistry.

For historical reasons discussed below, a few types of carbon-containing compounds, such as carbides, carbonates, simple oxides of carbon (for example, CO and CO), and cyanides are considered inorganic. The distinction between "organic and inorganic" carbon compounds, while "useful in organizing the vast subject of chemistry... is somewhat arbitrary".

Organic chemistry is the science concerned with all aspects of organic compounds. Organic synthesis is the methodology of their preparation.

For many centuries, Western physicians and chemists believed in vitalism. This was the widespread conception that substances found in organic nature are created from the chemical elements by the action of a "vital force" or "life-force" ("vis vitalis") that only living organisms possess. Vitalism taught that these "organic" compounds were fundamentally different from the "inorganic" compounds that could be obtained from the elements by chemical manipulations.

Vitalism survived for a while even after the rise of modern ideas about the atomic theory and chemical elements. It first came under question in 1824, when Friedrich Wohler synthesized oxalic acid, a compound known to occur only in living organisms, from cyanogen. A more decisive experiment was Wohler's 1828 synthesis of urea from the inorganic salts potassium cyanate and ammonium sulfate. Urea had long been considered an "organic" compound, as it was known to occur only in the urine of living organisms. Wohler's experiments were followed by many others, in which increasingly complex "organic" substances were produced from "inorganic" ones without the involvement of any living organism.
