The Absent Male in Little Women
The Absent Male in Little Women
The Absent Male in Little Women No gentlemen were admitted writes Louisa May Alcott in Little Women to describe the all-female private revue the March sisters perform. And as the novel progresses, one cannot help but wonder if this same sentiment does indeed echo throughout the novel, as male characters are conspicuously absent while all the pivotal parts are played by the women characters. This gender imbalance -- in that there are more female characters than male in Little Women -- is especi
Active Transport
Active Transport
Active Transport Since the cell membrane is somewhat permeable to sodium ions, simple diffusion would result in a net movement of sodium ions into the cell, until the concentrations on the two sides of the membrane became equal. Sodium actually does diffuse into the cell rather freely, but as fast as it does so, the cell actively pumps it out again, against the concentration difference. The mechanism by which the cell pumps the sodium ions out is called active transport. Active transport require
The Theory of Evolution
The Theory of Evolution
The Theory of Evolution The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. He also taught that only the fittest of each species would survive. He further postulated that the first living cell evolved in a warm warm little pond and that it took billions of years for the present diversity of living things to evolve. At the time, it was thoug

Technology There isn\'t hardly anybody around who can say their lives haven\'t been influenced by computers. Computers have all but taken over society as we know it. Everywhere you look, computers have greatly improved our lives. It can be as simple as going through a carwash, a computer processes the information that we feed it and adjusts the machine accordingly to give us the particular wash we paid for. Computers also play an extremely complicated role in one of the things that everybody use
Solar Energy and Its Social Consequences
Solar Energy and Its Social Consequences
Solar Energy and Its Social Consequences To understand the social consequences of solar energy, one must be aware of what solar energy is. Solar energy is a radiant energy produced in the sun as a result of nuclear fusion reactions. It is transmitted to the earth through space in quanta of energy called photons, which interact with the earth’s atmosphere and surface. The strength of solar radiation at the outer edge of the earth’s atmosphere when the earth is at its average distance from the sun
Vegetarianism
Vegetarianism
Vegetarianism Vegetarianism is the limitation of ones diet to only vegetables. Vegetarianism has been around for centuries, but recently we have seen the eruption of a more militant vegetarianism that is inspired by the animal rights movement. Today, vegetarian activists are throwing pies at Ronald McDonald and the Pork Queen, scrawling meat is murder in prominent locations, committing terrorist acts of arson, and waging media campaigns equating meat consumption with cannibalism.

Fusion: Our Future's Energy?
Fusion: Our Future's Energy?
Fusion: Our Future\'s Energy? Fusion energy seems to be the most promising energy source of the not-too-distant future. It is safe, it uses an energy supply that is so abundant that it will never run out, it gives off harmless waste, and it produces energy comparable to the Earth\'s sun! But are there any problems with this hopeful energy source? What is Nuclear Fusion? To understand fusion, it is a good idea to know about fission. This is the splitting of the nuclei of atoms into two or more s
Teenage Depression
Teenage Depression
Teenage Depression Teenage depression is a growing problem in today\'s society and is often a major contributing factor for a multitude of adolescent problems. The statistics about teenage runaways, alcoholism, drug problems, pregnancy, eating disorders, and suicide are alarming. Even more startling are the individual stories behind these statistics because the young people involved come from all communities, all economic levels, all home situations-anyone\'s family. The common link is often dep

Photography is a technique of producing permanent
Photography is a technique of producing permanent images on sensitized surfaces by means of the photochemical action of light or other forms of radiant energy. In today\'s society, photography plays important roles as an information medium, as a tool in science and technology, and as an art form, and it is also a popular hobby. It is essential at every level of business and industry, being used in advertising, documentation, photojournalism, and many other ways. Scientific research, ranging from
