The invention of nylon
1. In 1928 a team of researchers, led by organic chemist Wallace H. Carothers of the United States and sponsored by the chemical firm, set out to discover what sorts of materials they could produce from varying combinations of long-chain molecules. In a pioneering process called polymerization they combined atoms into long molecules that varied in the types of atoms used and the ways they were joined, producing an assortment of unique materials.
2. Then one day in 1930 they discovered an unusual property of one of their molten substances: it would stick to a glass rod and form a fine strand. As soon as the strand met the cold air, it solidified and formed a long continuous fiber that was both flexible and strong. If the fiber was then stretched to four or five times its original length, its properties changed further: it strengthened still more and at the same time became lustrous. Its structure was such that it could be spun into a fiber resembling silk, but it had high strength and elasticity and exceptional resistance to abrasion, rot, mildew, and chemicals.
3. For eight years chemists, physicists, engineers, and textile experts labored to develop this oddity into a usable fiber that could be manufactured on a large scale. In 1938 they announced their success. This synthetic textile fiber was to be called nylon.

Distance Education
1. Distance education programs are more popular than ever. College and high school students now have hundreds of legitimate distance education schools to choose from. Distance education is any type of schooling that takes place away from a physical campus.
2. There are two types of programs offered by distance education schools: synchronous learning programs and asynchronous learning programs. With synchronous learning, distance education students must log on to the school’s website at a set time. Often, they interact with their peers and professors via group chats, web seminars, video conferencing, and phone call-ins. With asynchronous learning, distance education students complete all coursework on their own time. They often learn via assignment sheets, message boards, email, pre-recorded video lectures, mp3s, and traditional mail correspondence.
3. Many students find that distance education courses give them the freedom to complete a degree while meeting their personal and professional obligations. Motivated learners are often able to complete distance education degrees in a fraction of the time often required. Distance education courses also allow students to network with participants from all over the nation.

Emotions
1. Emotions exert an incredibly powerful force on human behavior. Strong emotions can cause you to take actions you might not normally perform, or avoid situations that you generally enjoy.
2. In psychology, emotion is often defined as a complex state of feeling that results in physical and psychological changes that influence thought and behavior. Emotionality is associated with a range of psychological phenomena including temperament, personality, mood and motivation. According to author David G. Meyers, human emotion involves «…physiological arousal, expressive behaviors, and conscious experience».
3. The James-Lange theory is one of the best-known examples of a physiological theory of emotion. Independently proposed by psychologist William James and physiologist Carl Lange, the James-Lange theory of emotion suggests that emotions occur as a result of physiological reactions to events. According to this theory, you see an external stimulus that leads to a physiological reaction. Your emotional reaction is dependent upon how you interpret those physical reactions.

The Purpose of Emotions
1. Our emotions are composed of a subjective component (how we experience the emotion), a physiological component (how our bodies react to the emotion), and an expressive component (how we behave in response to the emotion). These different elements can play a role in the function and purpose of our emotional responses.
Our emotions can be short-lived, such as a flash of annoyance at a co-worker, or long-lasting, such as enduring sadness over the loss of a relationship.
2. Emotions can help us make decisions. Researchers have also found that people with certain types of brain damage that impairs their ability to experience emotions also have a decreased ability to make good decisions. Even in situations where we believe our decisions are guided purely by logic and rationality, emotions play a key role. Emotional intelligence, or our ability to understand and manage emotions, has been shown to play an important role in decision-making.
3. Emotions allow other people to understand us. When we interact with other people, it is important to give cues to help them understand how we are feeling. These cues might involve emotional expression through body language, such as various facial expressions connected with the particular emotions we are experiencing. In other cases, it might involve directly stating how we are feeling.

Developmental Theories
1. Developmental theories provide a set of guiding principles and concepts that describe and explain human development. Some developmental theories focus on the formation of a specific quality, such as Kohlberg's theory of moral development. Other developmental theories focus on growth that happens throughout the lifespan, such as Erikson's theory of psychosocial development.
2. Grand theories of development include psychoanalytic theory, learning theory and cognitive theory. These theories seek to explain much of human behavior, but are often considered outdated and incomplete in the face of modern research.
3. Minitheories describe a small, very specific aspect of development. A minitheory might explain fairly narrow behaviors, such as how self-esteem is formed or early childhood socialization. These theories are often rooted in the ideas established by grand theories, but they do not seek to describe and explain the whole of human behavior and growth.
4. Emergent theories are those that have been created fairly recently and are often formed by systematically combining various minitheories. These theories often draw on research and ideas from many different disciplines, but are not yet as broad or far-reaching as grand theories. The sociocultural theory proposed by theorist Lev Vygotsky is a good example of an emergent theory of development.
