Question # 1:

The right to free expression is a very important thing in a society - many of society's or an individual's ends are met through this right. Mill states that "To have a right, then, is, I conceive, to have something which society ought to defend me in the possession of. If the objector goes on to ask, why it ought? I can give him no other reason than general utility" (Utilitarianism, 1861). As a result, it can be inferred that rights are generally useful to the individuals who receive them, including the right to freely express oneself.

Free expression permits ...

It is sometimes very frustrating when you try to put on a switch and the light fails to come on. It becomes even worse when you have no idea on the possible causes of this problem.

Chapter 3 Atoms and the Periodic Table

For centuries, many have tried to learn about the smallest particle. As far as 2500 years ago, Democritus and Leucippus created an idea for the atom and called it ‘atmos’ meaning indivisible. Various philosophers and scientists have proposed models for what and how the atom should be. The initial theory proposed by Dalton in 1803 states that atoms are indivisible and that all atoms of a particular material are identical. He also stated that atoms of different materials join to form compounds. J.J. Thompson proposed the initial model of the atom. It is called the plum pudding model. He theorized ...

Power quality involving voltage occurs in two main ways. These include under voltage and overvoltage. Under voltage occurs when the power in transmission falls below 90% of the total power transmitted for a period of more than one minute. When the power is totally out, the situation is described as a blackout. When the power is fully present, it is simply said to be full power. There is a transition between full power and blackout that is described as brownout. Brownout is identified by dimming of lights, blackout by no lights at all, and full power by all domestic lights been well ...

A transformer is an electrical piece of equipment used in electrical circuits to alter the voltage of the electricity flowing in a circuit by either increasing the voltage (stepping up) or decreasing the voltage (stepping down) (Pansini, 1999). Alternatively, they may be described as static machines which transform power from one circuit to another while maintaining the electrical frequency constant. Transformers are, therefore, very important devices in the distribution of electricity. There are two main reasons why transformers are important in the process of electricity distribution: “Stepping up” and “stepping-down.”
First, once produced at the power station, the electric ...

Use Energy, Get Rich, and Save the Planet

In his article ‘use energy, get rich and save the planet’, John Tierney tries to prove that the use of more energy can be sustainable. He goes on to use mathematical models such as the Kuznets curve, to project the future energy use in the world. Furthermore, he goes on to discredit the models used in the 1970’s that they are skewed and time barred. These were the first models used by activists to predict the future of energy use. Tierney (2009) proves that these models did not have enough data to correctly predict the future use of ...
