Week 4- Multiplication and Division of Radical

This week I learned about multiplication and division of radicals.

When multiplying radicals you simply “just do it”.

Example: 2\sqrt{10} x 5\sqrt4 = 10\sqrt{40}

Dividing radicals is similar to fractions in the ability to reduce, but you cannot leave a radical in the denominator.

To get rid of a radical in the denominator you have to use conjugates.

Example: \frac{2}{\sqrt4-\sqrt2}\frac{\sqrt4+\sqrt2}{\sqrt4+\sqrt2}\frac{2\sqrt4+2\sqrt2}{\sqrt16+\sqrt4}\frac{\sqrt4+\sqrt2}{6}

Plot Point Photos – “Father and Son”

The goal of this project is to Identify the 8 plot points (by using quotes) of “Father and Son”, by Bernard MacLaverty. Under each plot point I also have to write 3-4 sentences explaining the quote. The story is about a father and son who reside in Ireland. They are involved in a conflict. The Son is associating himself with dangerous people. The father is trying to find out what’s going on to stop his son from getting hurt.

1) Exposition
: “I do not sleep. My father does not sleep… My son is breaking my heart. It is already broken. Is it my fault there is no woman in this house? Is it my fault a good woman should die?” (MacLaverty 16)

Explanation: This is the Exposition because we are further introduced to the characters. We find out that the mother has died. We also find out that their is some kind conflict between the Son and father, as the father mentions that his son is breaking his heart.

2) Rising Action
: “My son, he looks confused. I want you to talk to me the way I hear you talk to people at the door… I pulled you away from death once and now you will not talk to me. I want to know if you are in danger again” (MacLaverty 166)

Explanation: In this rising action we are further introduced to the conflict. We find out the details of conflict; such as the fact that the son had escaped death once, and he may be in serious danger again. We also see that the son and father don’t have a very close relationship. This all builds up the plot to the climax.

3) Rising Action
: “Son you are living on borrowed time. Your hand shook when you got home. I have given you the life you now have… Let me put my arm around your shoulders and let me listen to what is making you thin. At the weekend I will talk to him” (MacLaverty 167)

Explanation: This is a rising action. It builds up the plot and conflict by showing the reader that the father wants to help his son and find out what’s going on, but he keeps procrastinating and putting it off for later.

4) Rising Action
: “For two years, I never heard a scrape from you. I read of London in the papers. Watched scenes from London on the news, looking over the reporter’s shoulder at people walking in the street… Then a doctor phoned for me at work… ‘I had to go and collect you. Like a dog’” (MacLaverty 167-168)

Explanation: This is a rising action because it shows the reader that the Son has been in trouble before, and it’s very likely that he once again could be in serious danger. From this the reader can see that the Son doesn’t care for his father, while the father is very concerned for his son. This builds up the path to the climax.

5) Rising Action
: “The door swings open and he pushes a hand-gun beneath the pillow… ‘What’s that? Under your pillow?’” (MacLaverty 169)

Explanation: This is a rising action because it reveals that the Son owns a handgun. This builds up the conflict between the son and father. This also hints to the reader that the Son is most likely involved with dangerous people, and foreshadows what may happen next.

6) Climax
Quote: “There is a bang. A dish-cloth drops from my hand and I run to the kitchen door” (MacLaverty 169)

Explanation: This is the climax, because the whole story leads up to this moment. The story has been foreshadowing that the son is in danger, and how his father keeps trying to warn him. Here the reader sees that the conflict concludes in the Son getting shot.

7) Falling Action
Quote: “I take my son’s limp head in my hands and see a hole in his nose that should not be there” (MacLaverty 169)

Explanation: This is the Falling Action. The plot begins to wrap up; it confirms that the Son did get shot and is dying.

8) Denouement
Quote: “My son, let me put my arms around you” (MacLaverty 169)

Explanation: This is the Denouement, because this happens right after the climax and offers the reader the last pieces of information. It is an expository sad ending. All loose ends are tied up; the reader finds out that the Son does die, which the story has been foreshadowing. The father finally gets to hug his son.

Week 3- Absolute Value of a Real Number

This week in math I learned about the absolute value of a real number.

Absolute Value of a Real Number is defined as the principal square root of a square of a number or \sqrt{5^2}.

In other words Absolute Value of a real number is, the distance of from zero t0 a number on the number line, regardless of direction.

The symbol for absolute value is |x|.

The absolute value can never be negative, |-5|= 5.

Two Fishermen Sketch

Michael Foster is a tall, long legged man. He is most likely in his 20s, judging by the fact that he is described as being young, and he doesn’t have children. He is an ambitious small-town reporter. He is determined “to go to the city some day and work on an important newspaper” (1). In the story he meets a hangman named Smitty; who is scheduled to execute a man from Michael’s town. Michael’s fear is that he’s afraid of being seen with the hangman and being judged for being associated with him. Even though he enjoyed being around Smitty “he couldn’t figure out why he felt so ashamed of himself [every time he was with Smitty]” (4). Michael most likely has a college education as he has a profession which would require one.

Capital Punishment in “Two Fishermen”

Capital Punishment is when a person receives a death penalty for a crime they committed. There are five types of capital punishment: lethal injection, lethal gas, firing squad, hanging and electrocution. Canada in the 1860s was open to the idea of capital punishment, a person could be executed for murder and treason in Upper and Lower Canada. In 1961 murder was classified in two categories in Canada; capital and non-capital. Capital punishment was given for a deliberate murder and the murder of a police officer or guard while on duty. In 1962 the last death sentence was given out and in 1976 capital punishment was finally removed from the criminal code, but still remained in the Canadian National Defense Act, for the most serious military offenses.
If the story of “Two Fisherman” was based in Canada it could have taken place anywhere from the 1860s to almost a century later in 1976. This is because up to 1976 the premeditated murder of a civilian could have received capital punishment.

In my opinion, if “Two Fishermen” is taken place in present day US, then the death penalty was not justified for the situation. In the US the death penalty is given if a person commits one of six specific crimes. Thomas Delaney didn’t commit any of these six crimes and he shouldn’t have been hanged. Also, Thomas Delaney attacked Mathew Reinhardt in defense of his wife, so in my opinion he deserved some kind of punishment for killing Mathew Reinhardt but not capital punishment.

 

Nuclear Energy Debate

In my opinion nuclear power is an effective and safe option for producing energy. For the most part, nuclear reactors are environmentally friendly, they do not produce gasses like carbon dioxide or methane so they make much less greenhouse gasses and air pollution than other ways of making energy like coal, oil and gas. And, in the modern world where global warming and air pollution is a major problem, it is very important to use clean energy. A major arguing point for why Nuclear Energy is harmful to the environment is that the fuel that gets used up (nuclear waste) takes a very long time to decay, and can greatly harm the environment if the nuclear waste is illegally dumped into the environment. But this can easily be prevented if the Nuclear Waste is properly contaminated in a proper location. Also, as technology progresses we will find new, more effective ways of containing and getting rid of nuclear waste. Nuclear Energy is also cost effective, although it costs a lot to initially build a nuclear reactor, it is cheap to run it and the total cost is much cheaper than gas, oil and coal plants. Uranium is also much more energy efficient than coal and oil. 1 kg of coal can only generate 8 kWh, 1 kg of oil can generate 12 kWh of heat, and 1 kg of uranium-235 can generate 24,000,000 kWh of heat. As you can see, uranium is about 3,000,000 times more effective than coal.

Another big arguing point against nuclear power, is that an accident could happen which could have a devastating impact on the environment and any people that could be living around the nuclear power plant. Some famous examples of this is the Chernobyl disaster which occurred in 1986, and the Fukushima disaster which occurred in 2011. But these disasters only occurred because of bad staff management. The Chernobyl disaster happened because a station blackout simulation went wrong because of reactor design flaws and the reactor operators not following guidelines. And the Fukushima disaster occurred because the plant operator had failed to meet basic safety regulations. So, a well built reactor with a good staff that follows safety guidelines would have a very low chance of a catastrophic accident. Nuclear power is also very good for the local economy. It strengthens the local economy by providing jobs and through taxes. An average power plant pays about $40,000,000 annually to the workers. Each year a power plant pays around $67,000,000 in federal taxes, and $16,000,000 in local taxes, which helps schools and local infrastructure. The nuclear energy industry also creates many jobs, in the USA the industry makes 100,000 jobs. The jobs range from welders, to health physicists, to chemists.

In conclusion, the benefits of nuclear power far out weigh the disadvantages, and we should be more open to nuclear energy because when the alternative is coal and oil energy, which harms our already weakened environment, the clear winner is nuclear energy.

The Magic of Light

This magic trick is caused by the light refracting through the glass of water. The glass of water acts as a convex lens, as it refracts the arrow, the image becomes inverted, so the arrow looks like it is facing the other way. The image also looks like it’s bent because the index of refraction in the water is greater than the air, which changes the speed of the light therefore bending the light.
