\(\left(1-\frac{1}{2}\right)\left(1-\frac{1}{3}\right)\left(1-\frac{1}{4}\right)...\left(1-\frac{1}{2012}\right)\)

\(=\frac{1}{2}.\frac{2}{3}.\frac{3}{4}.\frac{4}{5}...\frac{2010}{2011}.\frac{2011}{2012}\)

\(=\frac{1.2.3.4...2010.2011}{2.3.4.5...2011.2012}\)

One day as I was in the field and my buffalo was grazing nearby, a tiger came. It asked why the strong buffalo was my servant and why I was its master. I told the tiger that I had something called wisdom. The tiger wanted to see it, but I told it I left my wisdom at home that day. Then I tied the tiger to a tree with a rope because I didn`t want it to eat my buffalo. I went to get some straw and said that it was my wisdom and burned the tiger. The tiger escaped, but it still has black stripes from the burns today.

The summer before my junior year in high school, my family and I took a trip to a completely new world. Being from a small town, I had never really been exposed to the elements of a large city such as New York City. My trip there was discovering an entirely new way of life that I had only heard stories of previously.

For about the tenth time the morning of the flight, I checked my room to make sure I didn’t leave anything essential behind. My stomach was doing flips as we arrived at the airport and made our way to the gate. It didn’t get much better than this: I watched through the window as the runway zoomed by and the buildings and houses became smaller and smaller as the plane gained altitude. An exhilarating feeling overcame me as I realized that I would soon be in one of the most amazing cities of the United States.

As we stood waiting for a taxi outside of the airport, it was immediately apparent to me that New York City was not the same as New Caney, Texas. It seemed everyone there was in a hurry to get to another place. The loud and constant sound of cars honking was heard throughout the entire trip. As soon as a car seemed to be going slower than the person behind him d, he would hear the horn of that car to let him know that he was apparently holding everybody else up! When we found our hotel in Times Square, I noed that it wasn’t just the cars that were in a hurry. Everyone in the streets was walking at a brisk pace that indicated a rush to be somewhere. The transportation of the city was also far different than anything that I had ever been exposed to. In my little town, a bike, a car, or even walking was perfectly suitable for getting around town, but in this foreign land, there were many more ways for one to get to another destination. Everywhere you looked, there were people hailing taxis, waiting on buses, rushing underground to the subway stations, walking franally, or desperately trying to maneuver their own cars through the busy streets. Just standing and watching the many people rushing their own separate ways was an interesting observation.

In addition to the people and transportation, the buildings were also an incredible sight. Each street was crammed with buildings that were built side by side with no room in between them, and a number of skyscrapers were present throughout the city as well. I was awestruck again as we went inside some of these buildings such as the Empire State Building and made our way towards the top. Standing outside of one of the top stories of the Empire State Building was awesome. I could hold the entire city in my hand from this view. I could even see Ellis Island a distance away from there. The stores were also large compared to the ones of my little town. A small retail store in New Caney would be a huge store that took up an entire building in New York. This would make it seem logical that the prices of everything in New York were almost triple those back home. It was as if the little peaceful neighborhood where I lived was magnified by 100 to make up the wonder city of New York.

My visit to New York City was a life changing experience. For the first time in my life, I was exposed to a little taste of what the real world is . The incredible modes of transportation, the huge skyscrapers, and all of the thousands of people made me anxious to grow up and perhaps move to an incredible city such as this one. Either way, my first trip to New York was one of the most incredible experiences of my life, one I will always treasure.

I had always wanted to visit South Korea and I recently had the chance to spend a week in this amazing country. Un its northern neighbor which is pretty much closed to visitors, South Korea is a welcoming and hospitable country. It is an interesting place with a unique culture and a highly developing economy.

I flew into the capital Seoul. On arrival in the city, it was the marked contrast between modern skyscrapers and high design shopping malls and shanty towns that was immediately striking. Wide streets lined by fancy boutiques lead to a labyrinth of narrow alleyways with tiny traditional shops and eateries and there is a clutch of great tourist attractions.

My tour itinerary began on Seoul’s main boulevard, Sejongro, because I wanted to see the Royal Palace (Gyeongbok), the President’s residence, known as Cheongwadae or the Blue House, and the American Embassy. From here it’s a fairly short walk to Bukchon where there is the city’s largest collection of privately owned traditional wooden houses. It’s a charm with beautiful architecture and small courtyards, with the houses interspersed with quaint cafes and art galleries.

Taking the same route the next day, I took a trip into the mountains that peak behind the President’s House, and climbed the one known as Bugaksan. This affords the opportunity to pass through the Sukjeongmun Gate and through the city’s ancient fortress wall. From here the Seoul Fortress is easily accessible and there are also amazing views of Seoul.

Shopping in the Orient is an amazing experience so I made sure to pay a visit to the Shinsegae downtown department store. This huge emporium sells probably everything you can imagine and is a complete charm in the way the bottom floors sell all the basic staples of daily life - including the ubiquitous kimchee (fermented cabbage) and are frequented by Korean housewives while the upper floors cater to the well-heeled and brand conscious. As fascinating as it is, the new rooftop garden is a welcome respite. But, if you are going to shop in Seoul, it’s a must to visit the street stalls and hawkers of the Namdaemum Market where the wares seem to be spread out in a blanket of never-ending stalls. Be prepared to be seriously jostled by the crowds, but it’s also the chance to feast on the best street food.

One of the most surprising sights and a rue delight is the Cheonggyecheon Stream. Running for just under 4 miles through the city, the stream is remarkably quiet given its location, because it is 15 foot below street level. The serene setting, accentuated by waterfalls and bridge is a favorite strolling spot for roman couples.

With a flying visit to Itaewon, the popular ex-pat neighborhood near to the main US army base, my time in Seoul came to an end. I was enthralled and captivated and hope I get to return one day.
