An Inconvenient Turth Essay Example for Free

An Inconvenient Turth Essay My reason for picking this topic is, because I would like to know more about global warming. What are the real danger`s that we are facing due to global warming? What can we do to stop the exceeding rapid rates of global warming? I would like to imform other about the new knowledge that I obtain on the subect of globle warming. Al Gore tell how people use to Think about global warming that the world was big enough and we would never have a problem. He also describes global warming as when the sun`s radiation comes in, in the form of light waves passing through earth atmosphere to heat the earth,and then it is re-radiated back into space in the form of infrared radiation, and some of the out going infrared radiation is trapped by the earth atmosphere and warms it. This thin layer of atmosphere is being thicken by all of the global warming pollution that`s being put up there. He speaks of Mr. Roger Revelle as the first person to propose measuring carbon dioxide in the earth`s atmosphere. After the first years of data he intuited what it meant for what was to come. He and a team of other designed the experiment in 1957 with the help of Mr. Charles David Keeling. they started sending these weather balloons up every day. The results of his measurements after only a few years it was startling. He drew the connections between the larger changes in our civilization, and this pattern that was now visible in the atmosphere of the entire plant, and then he projected into then future where this was headed unless we make some adjustments. Mount Kilimanjaro had icecaps 30 years ago. and now it has all melted. Mr. Lonnie Thompson, studies glaciers, and predicts there will be no more snows of Kilimanjaro within the next decade. Its also is happening in Glacier National Park, and all around the world the ice is now gone. He mentions about CO2 and temperature, when there is more carbon dioxide, the temperature gets warmer. He speak of this not so much as a political issue,but a moral issue. It is deeply unethical. He had a lots of faith in the democratic system that these finding would be compelling enough to cause a real change but they were n`t. He speak about when the oceans get warmer that cause stronger storms leading to a lots of big hurricanes and a all time record in the U.S. of tornado, and in Japan record set for typhoons. He contribute the changing of the season to global warming and changing nature plans. He also says that the burning of forests and brush fires causes more co2 to be pit into the air.what all of this means is our ability to a have a future to live in the earth. I really enjoy the movie The movie was very informing I got a better idea about what is happening around the world. I agree with Al Gore something must be done. It was amazing to me about how everything connect together like a domino effect. I picture in my mind how all these great mountains all around us is melting which is changing the temperature of the sea, which cause many of the world`s disaster by storms. Man is destroying himself. It makes me think can we go back where their was not a lots of invention that polluted our air. Can we truly find a solution to this mas, mass, mass, problem are have we went to far of no return. I think about the air we breathe and the water we drink. I remember only about 40 yrs.ago when I was ten years old, my grandmother showed me where I could drink out a spring it was so clean and beautiful and fresh tasting, I hate to think if I when back there to drink what kind of substance would be in that water now. Everything is being effected our food, the animal niches,and season is changing we can`t tell winter from fall or spring from summer and the insects can`t tell neither. If we have gone to far to stop all the problems, why not do, what we can do, to correct what we can, for the future of our life on the earth.

Terrorists Attack: a Media Analysis :: essays research papers

Terrorists Attack!!   Ã‚  Ã‚  Ã‚  Ã‚  February 26, 1993, the day that terrorists made the biggest attack on American soil to that point. It was early afternoon on a Friday, 12:18 pm to be exact, a car bomb ripped through the guts of the now infamous North World Trade Center twin tower. It happened very quickly, and without warning, normal people were simply going about their daily business, when all of a sudden, the building shook, the power went out, and smoke began to fill all 110 floors of the towers. Many wondered what had happened, had a plane struck the building, was it an earthquake? D, none of the above, some crazed maniac had decided to kill 5 people and injure many more just to get some point across.   Ã‚  Ã‚  Ã‚  Ã‚  This event graced the front page of newspapers and news magazines across the country, the New York Times was the newspaper closest to the action. Covrage in this newspaper was published one day after the event, and coverednot only the event but the ensuing traffic chaos it caused. Being a newspaper local to New York City, the site of the attack, the newpaper catered to the interests of its local readers. The New York Times, however, is also circulated around the country, and around the world. This required the newpaper editors, publishers, and writers to remain sensitive to the feelings and thoughts of readers in the broader reading audience.   Ã‚  Ã‚  Ã‚  Ã‚  Newsweek Magazine also published coverage of the attack. Their primary audience is a national one, and consequently, the coverage is geared toward a broader audience. Also, seeing as the magazine is only published once a week, rather than daily as the New York Times, Newsweek had more time to gather facts and evidence. This added time for research leads more to a fact based coverage than a question based coverage.   Ã‚  Ã‚  Ã‚  Ã‚  One interesting observation is that it seems both sources immediately assume that foreign terrorists were the primary perpetrators of this attack. Neither article comes right out and says it, however both are rather ambiguous about it. Newsweek does mention the possibility of a domestic source for the violence, but spends much more time and effort explaining the possible foreign sources. Overall both articles seem rather straightforward in their representation of the event, and remain rather simplistic, so as not to confuse the reading audience.   Ã‚  Ã‚  Ã‚  Ã‚  When an event of this magnitude occurs, emotions are bound to play a role in the coverage.

Jonghyun Choe March 25 2011 Math IB SL Internal Assessment – LASCAP’S Fraction The goal of this task is to consider a set of fractions which are presented in a symmetrical, recurring sequence, and to find a general statement for the pattern. The presented pattern is: Row 1 1 1 Row 2 1 32 1 Row 3 1 64 64 1 Row 4 1 107 106 107 1 Row 5 1 1511 159 159 1511 1 Step 1: This pattern is known as Lascap’s Fractions. En(r) will be used to represent the values involved in the pattern. represents the element number, starting at r=0, and n represents the row number starting at n=1. So for instance, E52=159, the second element on the fifth row. Additionally, N will represent the value of the numerator and D value of the denominator. To begin with, it is clear that in order to obtain a general statement for the pattern, two different statements will be needed to combine to form one final statement. This means that there will be two different statements, one that illustrates the numerators and another the denominators, which will be come together to find the general statement.To start the initial pattern, the pattern is split into two different patterns; one demonstrating the numerators and another denominators. Step 2: This pattern demonstrates the pattern of the numerators. It is clear that all of the numerators in the nth row are equal. For example all numerators in row 3 are 6. 1 1 3 3 3 6 6 6 6 10 10 10 10 10 15 15 15 15 15 15 Row number (n)| 1| 2| 3| 4| 5| Numerator (N)| 1| 3| 6| 10| 15| N(n+1) – Nn| N/A| 2| 3| 4| 5| Table 1: The increasing value of the numerators in relations to the row number.From the table above, we can see that there is a downward pattern, in which the numerator increases proportionally as the row number increases. It can be found that the value of N(n+1) – Nn increases proportionally as the sequence continues. The relationship between the row number and the numerator is graphically plotted and a quadratic fit determ ined, using loggerpro. Figure 1: The equation of the quadratic fit is the relationship between the numerator and the row number. The equation for the fit is: N= 0. 5n2+0. 5n or n2+n2, n>0 Equation 1 In this equation, N refers to the numerator.Therefore, N= 0. 5n2+0. 5n or n2+n2, n>0 is a statement that represents step 2 and also step 1. Step 3: In relation to table 1 and step 2, a pattern can be drawn. The difference between the numerators of two consecutive rows is one more than the difference between the previous numerators of two consecutive rows. This can be expressed in a formula N(n+1) – N(n) = N(n) – N(n-1) + 1. For instance, N(3+1) – N(3) = N(3) – N(2) +1. Using this method, numerator of 6th and 7th row can be determined. To find the 6th row’s value, n should be plugged in as 5 so that N(6) can be found.As for the 7th row’s numerator, n should be plugged in as 6. 6th row numerator is therefore: N(5+1) – N(5) = N(5) – N( 4)+1 N(6) – 15 = 15 – 10+1 N(6) = 15+6 N(6) = 21 7th row numerator is therefore: N(6+1) – N(6) = N(6) – N(5)+1 N(7) – 21 = 21 – 15 +1 N(6) = 42 – 15 + 1 N(6) = 28 Not only by this method, but from the equation found in step 2, figure 1, 6th and 7th row numerator can be found also. 6th row numerator: N(6)=0. 5? 62+0. 5? 6 N(6)=0. 5? 36+3 N(6)=21 th row numerator: N(7)=0. 5? 72+0. 5? 7 N(7)=0. 5? 49+3. 5 N(7)=28 Consequently, these are the values of numerators up to the 7th row. 1 1 3 3 3 6 6 6 6 10 10 10 10 10 15 15 15 15 15 15 21 21 21 21 21 21 21 28 28 28 28 28 28 28 28 Using the method in step 3 and equation 1 in figure 1, it is evident that the numerator in the 6th row is 21. Since both equations have brought same values, it can be concluded that equation 1 is a valid statement that demonstrates the pattern of the numerator.Equation 1 will be used later also, in order to form a general statement of the pattern of whole LACSAP Fract ions. Step 4: When examining the denominators in the LASCAP’S Fractions, their values are the highest in the beginning, decreases, and then increases again. For example, the denominators in row 5 are; 15 11 9 9 11 15. From this pattern, we can easily see that the equation for finding the denominator would be in a parabola form. Element | 0| 1| 2| 3| 4| 5| Denominator | 15| 11| 9| 9| 11| 15|The relationship between the denominator and the element number is graphically plotted and a quadratic fit determined, using loggerpro. Figure 2: This parabola describes the relationship between the denominator and element number. The equation for the fit is : D = r2 – nr+r0 . In this equation, r refers to the element number starting from 0, and r0 being the first denominator value in the row. n refers to the row number starting from 1. To see if this equation work, the 3rd denominator value in the 3rd row was measured. D = 22 – 3 ? 2+6 D = 4 – 6 +6 D = 4With this equat ion, it is evident that the 6th and 7th row denominator values can be found. We already know the first and last denominators from when numerators were found; which are 21 and 28. 6th row second and sixth denominator: D = 12 – 6 ? 1+21 D = 1- 6+21 D = 16 6th row third and fifth denominator: D = 22 – 6 ? 2+21 D = 4- 12+21 D = 13 th row fourth denominator: D = 32 – 6 ? 3+21 D = 9- 18+21 D = 12 7th row second and seventh denominator: D = 12 – 7 ? 1+28 D = 1- 7+28 D = 22 7th row third and sixth denominator: D = 22 – 7 ? +28 D = 4- 14+28 D = 18 7th row fourth and fifth denominator: D = 32 – 7 ? 3+28 D = 9- 21+28 D = 16 Now, since the denominators in the 6th and 7th row are found, the sixth and seventh rows can be drawn and added in the LACSAP’S Fractions. Consequently, these are the fractions up to the 7th row. 1 1 32 1 1 64 64 1 1 107 106 107 1 1 1511 159 159 1511 1 1 2116 2113 2112 2113 2116 1 1 2822 2818 2816 2816 2818 2822 1 Now th at the patterns for the LASCAP’S Fractions are found, all fractions can be expressed in the form En (r) when it is the (r+1)th element in the nth row, starting with r=0. The general statement of the pattern is clearly found when using the equations for the nominator and the denominator.Therefore, the general statement for En r will be En (r) = 0. 5n2+0. 5n r2 – nr+r0 In order to see if the equation works correctly, we can plug in number and figure out if the general statement works out. For example, E7 (3) = 2816 = 0. 5n2+0. 5n r2 – nr+r0 = 0. 5 ? (7)2+0. 5 ? (7) 32 – 7? 3+28 = 2816 . Here, it is clear that the formula is applicable. In order to make sure that the general statement is valid, finding the additional rows of the recurring sequence of fractions by using the general statement above would be useful.Here, I chose to settle on 2 additional rows which are the 8th and 9th rows in the pattern. 8th row numerator: N(8)=0. 5? 82+0. 5? 8 N(8)=0. 5? 64+4 N8=36 9th row numerator: N(9)=0. 5? 92+0. 5? 9 N(9)=0. 5? 81+4. 5 N9=45 8th row second and eighth denominator: D = 12 – 8 ? 1+36 D = 1- 8+36 D = 29 8th row third and seventh denominator: D = 22 – 8 ? 2+36D = 4- 16+36 D = 24 8th row fourth and sixth denominator: D = 32 – 8 ? 3+36 D = 9- 24+36 D = 21 8th row fifth denominator: D = 42 – 8 ? 4+36 D = 16- 24+36 D = 28 9th row second and ninth denominator: D = 12 – 9 ? 1+45 D = 1- 9+45 D = 37 9th row third and eighth denominator: D = 22 – 9 ? +45 D = 4- 18+45 D = 31 9th row fourth and seventh denominator: D = 32 – 9 ? 3+45 D = 9- 27+45 D = 27 9th row fifth and sixth denominator: D = 42 – 9 ? 4+45 D = 16- 36+45 D = 25 Thus, these are the fractions up to the 9th row. 1 1 1 32 1 64 64 1 1 107 106 107 1 1 1511 159 159 1511 1 1 2116 2113 2112 2113 2116 1 1 2822 2818 2816 2816 2818 2822 1 1 3629 3624 3621 3628 3621 3624 3629 1 1 4537 4531 4527 4525 4525 4527 4531 4537 1 This shows th at the general statement for the symmetrical, recurring sequence of fractions is valid and will continue to work.

Stockhausen Life and Works - 614 Words

Composer Karlheinz Stockhausen was born August 22, 1928 in the small town of Mà ¶drath located just west of Cologne Germany. He was the first child of three born to Simon and Gertrud Stockhausen. Early in his life, the Stockhausen family struggled financially. Germany was in a low point of stability after WWI and most people had trouble making ends meet. Simon Stockhausen, a teacher at the time, was forced to move from one temporary post to another on average twice a year. Unfortunately in 1932 when he was four years old, Stockhausen’s mother Gertrud was committed into a sanatorium. This was likely due to the depression she encountered associated with the instability, poverty, and having three children so close to one another. In 1935 Shortly after his wife became ill, Simon Stockhausen was promoted to head teacher at a small village school located in Altenburg. The newly formed Third Reich led by Adolf Hitler used him in this position to influence the local community by s preading propaganda and organizing fundraisers for the new movement. Karlheinz Stockhausen showed an early interest in music and the family piano. The family also owned a radio that young Stockhausen listened to and attempted to imitate. When he was seven, Karlheinz was enrolled in school and began his first piano lessons with the organist of the local Protestant church. He practiced often and learned to play back music he heard on the radio.
