Identity is in Flux Because of Environment

- 1) Identity refers to how one conceptualizes oneself in some form of social context, and is usually considered as a personal attribute in sociological and psychological research. However, one’s identity of self is dynamically mediated by their environment and is constantly in flux. Who someone is and who they want to become are affected by the availability of resources and opportunity in their environment, the expectations of others, and the social, cultural, and historical contexts in which they seek to identify themselves (Holland et al....   [tags: social, science, academics]

Heraclitus - Permanent Flux

- Permanent Flux It is said that every great journey begins with one step. This is not true. A more accurate saying would be, “every great journey begins with the idea of the journey”, thus leading to the idea of the step, and so on. The steps will surly follow an idea, but nevertheless the ideas will always precede any action. Once one gets an idea in one’s head, one must either forget it, or act on it.

Invention Relating to Alloy of Copper

- The present invention relates to an alloy of copper having high conductivity and low resistivity. Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electric charge is the property of matter that causes it to experience a force when close to other electrically charged matter. Conduction in metals must follow Ohm's Law, which states that the current is directly proportional to the electric field applied to the metal. The key variable in applying Ohm's Law is a metal's resistivity....   [tags: ohm , conductivity, resistivity]

Being is existence itself, doing is action, its known to be always in flux, always changing, showing doing is performing and is also always changing, and explaining showing doing is the work of performance studies. Subjectivity is always in flux, it is always changing because people’s surroundings and influences change which leads to there opinions to change also. Richard Schechner states that performances are made of “twice-behaved behaviours” which means restored behaviours that become so natural to people that it is like a routine for them....   [tags: performance and performativity ]

The Earth Magnetic Field

- It’s the magnetic field that extends from the earth’s interior to where it meets the solaria stream of charged particles emanating from the sun. The magnetic field resembles the field of a large bar magnet near its center or that due to a uniformly magnetized sphere. Its origin is thought to be generated deep down in the earth’s core. At the surface of the earth, the pole of this equivalent bar magnet, nearest the north geographical pole is actually a south” magnetic pole. This paradoxical situation exists since by convention a north seeking end of a compass needle is defined as pointing north yet must point to a pole of opposite sense or South Pole of the earth’s magnetic field....   [tags: solaria stream, magnetic storms]

The Theories of Truth

- ... Take, for example, the correspondence theory which states a truth must correspond to a fact. First, we must define what fact is. Perhaps one definition is something that can be physically verified and always be the case. What, then, of moral truths. The correspondence theory holds a strikingly weak position on these, as moral truths are hard, if not impossible, to correspond with a fact. After all, how do we ensure something is a fact if it’s intangible and unverifiable, and seem to be in constant flux....   [tags: correspondence, coherence, pragmatist]

Ratio of Charge to Mass for the Electron

- Ratio of Charge to Mass for the Electron Introduction: The object of this lab was to determine the measure of the ratio of an electron to its mass. This is done by accelerating a stream of electrons through a measured potential difference. The stream of electrons moves through a uniform magnetic field. It is perpendicular to the velocity of the electrons. The path of the electrons is circular because of this fact. The ratio of e/m can be found by the relationships between the measured accelerating potential difference, the diameter of the circular path described by the electron, and the magnetic flux density....   [tags: Papers]

Misconceptions about Human Behavior in To Kill a Mockingbird

- How do we define normal human behavior. In order to determine the answer we must first determine what behavior really is, the conclusion is easy enough to reach: Human behavior derives from reactions to internal or external stimuli (Salvador); these reactions bring about emotions that dictate a particular response or behavior. These become part of a person’s personality, which defines their behavior, due to this, a person’s behavior is able to adapt to the stimuli with their environment and thus the definition of “normal behavior” is in a state of constant flux....   [tags: To Kill a Mockingbird Essays]

Superconductors and Superconductivity

- Before Kamerlign Onnes, in 1908, was able to liquefy helium and bring its temperature down to about 1K, it had been known that the resistance of a metal falls when cooled below room temperature. However, it was not known what value the resistance would approach if the temperature was reduced towards 0K until Onnes, while experimenting with platinum, discovered that, its resistance fell when cooled to a very low value that depended on the metal’s purity. As the temperature of mercury was reduced toward 0K, the value of the resistance would fall smoothly until the resistance fell extremely suddenly at about 4K....   [tags: physics science superconductor]

This is especially true when looking at history from an oral historian’s perspective.

Rather, once a hypothesis is proposed, evidence can be generated in favor of the hypothesis or in favor of an alternative hypothesis. When enough evidence is gathered in one direction or the other, the original hypothesis is either accepted or debunked in favor of an alternative. As scientific work is always in flux, any previously accepted theory can always be overturned by new evidence.1, 2 Many epidemiologists accept Popper’s thesis that causality can never be truly proven; although, once enough reliable evidence has been accumulated, a causal relationship can be inferred.2 The question o...   [tags: Scientific method, popper's theory, causality]
