It is not a strange realization to see that walking foot over foot on a tightrope takes balance in any scenario. The ability to walk on a tightrope however does revolve physics and its properties. Angular rotation, (w=L/I), angular momentum, (L=IW), and moment of inertia,(I=mr^2), are three major physical categories and characteristics that play a part in a tightrope walker’s ability to stay on the rope and not fall to his potential demise. But how does a tightrope walker increase his chances of staying on the rope? Often times one can see a tightrope walker carrying a large pole, a pole with heavy weights on the end, bending his knees, or extending their hands outward. All of these actions help to increase the ropewalker’s chances of success. Picture the rope as the axis. When a tightrope walker embarks on his journey, he must stay constantly positioned over that axis to maintain balance. Carrying a pole horizontally helps to distribute the ropewalker’s mass laterally in a direction away from the axis, or rope. Having a pole in hand helps to increase stability because the ends of the pole are constantly being acted upon by a variety of forces that are trying to change their position in the air with every step. The heavier the pole the more force will be needed to alter the poles position and begin rotation around the rope. Heavy weights can sometimes be placed on the end of the pole increasing stability. More force will be needed to move the heavier pole. The weights essentially amplify the pole’s effect helping the walker stay on the rope. Torque also acts on the ends of the poles. Since both sides are being acted upon, the torque forces balance each other out. The moment of inertia is also an essentially physical property to account for when walking on a tightrope. In easier terms, the moment of inertia is basically the walker’s resistance to angular rotation about the axis (rope). The heavier the tightrope walker is (mass of themselves, pole, and potential weights on the ends) the higher the moment of inertia. The pole will increase the ropewalker’s moment of inertia and his resistance to rotate angularly about the axis. The weights on the end of the pole also increase the moment of inertia further. With an increased moment of inertia, there will be a decreased potential of angular momentum and angular rotation around the rope that could result in a fall or worse. The angular momentum will be decreased as the pole’s weight increases. The heavier the pole, the more the pole will bend towards the rope ultimately lowering the ropewalker’s center of gravity. The lower the center of gravity the higher the percent of stability.

Tightrope Walking Art

...walked on the wire that connected between towers at height a hundred and ten stories. He created art through his skill, bewitched everybody who saw his walk. His imagination and passion is almost impossible for other people. Is it art? Yes, tightrope walk between the Twin Tower is very creative and significant art. To create art, of course, people need to take time to build their skill. It didn’t happen over a night. What do you think of Mr.Petit’s tightrope walking? His creative skill and imagination are amazing. Mr. Petit spent most of the time to build his skill. He failed several times, but he never gave up. He went back and forth from his country to New York to create his art. He devoted all his efforts into it for his whole life. He has a great passion, perseverance. We could see it. It is a lot more difficult to create his art than any other arts. His imagination is different from any others. He did something that might be a dream for others. His creation isn’t normal. He bet his life to create his art. It is a signification art. As an artist, his job is to immerse his viewers into a world that he has built. In the book, ‘let the great world spin’, by Colum McCann, he described that how people were gripped by the tightrope walking. “They found themselves in small groups together beside the traffic lights on the corner of Church and Dey; gather the awning of Sam’s barbershop. Doctors, Cleaners, Diamond merchants, Fish seller…” Those people have their own......

Key to Life

...A man travels the world in search of what he needs and returns home to find it ~ George Moore I want all of you to pause for a moment and think about our miserable existence in trying to meet the demand from work and family lives. Most of us live like a tightrope walker. I am a living example… giving most of our time at work, balance, if any, to our family, nothing for friends, getting not enough sleep and repeat the same again and again. This is what we fondly call work-life-balance. Do you really want to live like a tightrope walker struggling between the abyss of work and life? There are thousands and thousands of desperate people who work long hard hours of job that they hate, to enable them to buy things that they need to satisfy the people that they like. The governments and corporates are not going to solve this problem for us. It is for us as individuals to take control and responsibility for the type of life that we want to lead. If you don’t design your life, others will design it for you and you may not like their idea of balance. It is particularly important that you don’t leave the quality of your life in the hands of commercial organizations. This is true for all commercial companies, because they are inherently designed to get as much of you as they can. It is in their nature and is embedded in their DNA. We have to be responsible for setting and enforcing the boundaries of balance that we want in our lives. We have to be careful with the......

...Disease Control and Prevention (CDC). And, when it comes to serious injuries, more than 90 percent of hip fractures are caused by falls. Regularly doing a few gentle, at-home exercises may help your elderly loved one enhance their coordination and decrease their risk of falling. The following movements should be done next to a person, chair, or railing, that can be used for balance in case your loved one becomes unsteady. A senior should not engage in exercises that seem overly challenging, unless they have been given the go-ahead by their doctor. Here are five quick exercises that a senior can do to improve their balance: 1 Tightrope walk: Just like a tightrope walker in a circus, this exercise requires elders to hold arms straight out from their sides, parallel to the floor. With arms positioned like this, ask your loved one to try walking in a straight line, pausing for one or two seconds each time he or she lifts their back leg off of the ground. Have them take between 15 and 20 steps this way. While they walk, tell them to try looking at a spot...

...Transport or transportation is the movement of people, animals and goods from one location to another. Modes of transport include air,rail, road, water, cable, pipeline and space. The field can be divided into infrastructure, vehicles and operations. Transport is important since it enables trade between people, which in turn establishes civilizations. Transport infrastructure consists of the fixed installations necessary for transport, including roads, railways, airways, waterways, canalsand pipelines and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations) and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Vehicles traveling on these networks may include automobiles, bicycles, buses, trains, trucks, people, helicopters and aircraft. Operations deal with the way the vehicles are operated, and the procedures set for this purpose including financing, legalities and policies. In the transport industry, operations and ownership of infrastructure can be either public or private, depending on the country and mode. Passenger transport may be public, where operators provide scheduled services, or private. Freight transport has become focused oncontainerization, although bulk transport is used for large volumes of durable items. Transport plays an important part in economic growth and globalization, but most types cause air......

...nerve racking as I probably fall into the slightly shy category.   So I started thinking about some of these things I do everyday, and decided I was going to take my dog for a walk.   But this time instead of looking forward as do most human beings, I would walk backwards, and let my dog lead me through the park.   This was my first idea and I figured I would give it a try and see if I got reactions from people.   The park where I was walking was completely packed with people because it was a Saturday morning.   I couldn’t help but crack a smile as the people around me started to stare at me like I was completely retarded.   I’m sure in some ways they were right.   I kept walking, nearly trampling over an old man who was power walking.   He gave me a confused look, and I could tell he wanted to tell me off.   At first all of the looks made me feel very uncomfortable, but then I started to become very amused with myself.   I felt like I was in a jackass bit, or in a candid camera show. I’m not sure there is any place in the world where walking backwards is normal.   As simple as this experiment was, it was very...

...feet upon that buckling concrete walk, to step over grassy seams and make your way, hands in pockets, through the silences, that was what Mr Leonard Mead most dearly loved to do. He would stand upon the corner of an intersection and peer down long moonlit avenues of pavement in four directions, deciding which way to go, but it really made no difference; he was alone in this world of A.D., 2053 or as good as alone, and with a final decision made, a path selected, he would stride off, sending patterns of frosty air before him like the smoke of a cigar. Sometimes he would walk for hours and miles and return only at midnight to his house. And on his way he would see the cottages and homes with their dark windows, and it was not unequal to walking through a graveyard where only the faintest glimmers of firefly light appeared in flickers behind the windows. Sudden grey phantoms seemed to manifest upon inner room walls where a curtain was still undrawn against the night, or there were whisperings and murmurs where a window in a tomb-like building was still open. Mr Leonard Mead would pause, cock his head, listen, look, and march on, his feet making no noise on the lumpy walk. For long ago he had wisely changed to sneakers when strolling at night, because the dogs in intermittent squads would parallel his journey with barkings if he wore hard heels, and lights might click on and faces appear and an entire street be startled by the passing of a lone figure, himself, in the......

Journey of the Self: Example Through Symobols

... a pack of cigarettes with a lighter, a bottle of water and a couple of granola bars. In my pockets I have a cell phone with a dead battery, a pocketknife, and my wallet with five dollars and my I.D. inside. I’m walking, surrounded by trees of all types. There is a light breeze, but it’s quiet as I walk and look around. As I’m walking, the road is flat and somewhat narrow, but it is easy going for the most part, with random spots where the road becomes rocky and somewhat stressful, but it evens itself out and becomes smooth for a period of time again. I feel happy and serene, but exhausted at times and in need of a bit of rest, but I always continue and begin to walk again. As I’m walking, I come to a two-way fork in the road with a sign in the middle. The sign has two arrows with words printed on them. Each arrow is pointing in the opposite direction of the other. To the left I have the choice to walk to the city, while to the right I have the choice to walk to a small country town. After some thought and consideration of both of my choices, I eventually choose to head towards the Country. I’m not sure exactly why I decided to head this way, but something inside of me tells me that it is the way that I need to go. A sense of fate you could call it. As I’m walking down the path I chose all of a sudden there is a fallen tree blocking the road. The tree is a large Redwood tree, whose width is roughly four and a half or five feet wide. I could walk around it, but since I am......

...cold damp wind swirled around my body as I walked on the pathway of the dimly lit street. Winter is arriving with a vengeance. My hands are frozen, yet, I have a sweat up from walking to a steady pace for so long, must have walked at least two kilometres now. I cannot see if the street ends or turns, it is too dark to work out, the street lights are placed erratically, not like to city lights where I am from. I thought she said “follow the main road”. Well, I am on the main road, a dark, dimly lit main road. I looked back, did I miss another point of direction. I am to turn left after Tot Spot and the Scarlet Women sign advertising a play currently running. Oh, at last, there is the early childhood centre, not much of a childhood centre if you want my opinion. So, where is the Scarlet Women sign? I am getting worried now, after thirty minutes, I should have reached her home by now. I’m going back to ‘Tot Spot’ and start again. Some directions, the Scarlet Women sign is on the other side of the road, facing the other way. My blood pressure is rising, I’m starting to get emotional and stressed. Uh, I should have written down those instructions. Okay, go over one more time in my head, what did she say to me on the phone? Forty minutes from the swimming centre. Walking distance, that’s what she said, walking distance. Swimming Centre, Shopping centre, Tot Spot, Scarlet Women, passed all of those, what have I missed? Here it is; the alley-way shortcut to her street. That’s......

...You should invest in my company, “Shady Dogs”, because our pets deserve the same protection that we would provide our children or ourselves.  During those rainy days, it’s more difficult to take our pets on a walk because they always return home wet, and the smell of “wet dog” plus the mess that ensues creates more work for us in our already busy lives.  Instead of bringing home your cold, wet dog, you can now buy them the protection they’ve been waiting for.  With the simple design of a walking harness that many of us are already accustomed to, my product has the added benefit of an attached umbrella to shade and protect our four legged friends from harsh environmental elements.  This patent pending design allows even weight distribution so that the umbrella harness can be comfortably worn on the animal's back. You can even use our device during the hot summer months to shield from the damaging effects of the sun’s harmful rays.  Of course, we offer these umbrella harnesses in different sizes and colors because no dog is too big or too small to be left out in the rain.  They range from $20-$35 depending on the size of the dog and are available in all major retail pet stores.  The cost to produce each harness ranges from $4-$6 so there is plenty of room for profit.  We have already sold 100,000 units this year and project 250,000 in the upcoming year.  We are also developing additional products to grow our business and are looking for investors to aid in production and......

...think about their privacy not safety. If we are not thinking about safety we cannot live easily. That’s why most of all the people get into trouble. Therefore safety is more important than privacy. First of all for instance when people’s majilis members shout at there, they never think about their safety. They always think that their privacy is most important. So when the policemen come to arrest them, they are saying it’s our privacy, but what about their safety? When the member is arrested all will talk about that, then the member and the member’s family will be embarrassed to go out of their houses. So whether the person is a member or an ordinary they should think about safety. Secondly for instance when a person is walking in a road they are walking freely and another person come and disturb that person and pick some important thing of that person. That time did he/she think of privacy? Actually that time if that is me also think about safety. So in anywhere in the world safety is more important. Another thing is that when we are in the airport and the flight is flying than we should think about safety. We cannot sit as we want, we cannot speak as we want and we cannot walk as we want. If we are running in the airport we might fall. So in that time we have to think about safety not privacy. In sea transport we are going to another island we have to about safety. If someone fell to sea, than in that we will do if we think about only privacy. What will happen if we......

Blood Lactate

...Title: Blood lactate Introduction: Measuring blood lactate concentration provides information not only about changes in glycolysis (1) but also about anaerobic work capacity (2). The point where heart rate or running pace at which lactic acid begins to accumulate is called the Lactate Threshold. This measurement is also sometimes called the anaerobic threshold or onset of blood lactic acid. The lactate threshold measurement is very valuable as it is one of the more sensitive indicators of fitness level. For example, if training is ineffective the lactate threshold will be reached at a relatively low running speed; with more effective training the threshold will be achieved at a higher speed. Elite athletes reach the lactate threshold at a much higher running speed than sub-elites. The threshold is, once again, a function of effective training and also genetics. Many scientific studies indicate that the lactate threshold is one of the best predictors of distance running performance.

...My experiment was to give up something in my life for four days and see how it changed my schedule and what I did during the day. I chose to give up watching TV for this experiment. I chose this specific thing because it takes up a lot of my free time at home and at night, and it isn’t an essential thing that I need to have so I was curious on the effects not having TV would have. Another reason I gave up TV is because of the frequency I watch TV and because I made TV my default thing to do when I am bored I was curious how I would manage the extra time of if there was going to be any extra time. I am very proud to say I didn’t cheat through this whole experiment, although there were some close call where I almost forgot or really wanted to watch TV and relax, I restrained myself and received the full experience that this experiment was suppose to give. Going into this experiment and in the beginning I didn’t think the lack of TV would change anything in my day to day life, especially since it was only for three days. As I soon learned I was very wrong. Pretty quickly I noticed I had much more time and in the beginning I had nothing to fill my time with. At first I went to the gym or went on a walk of did something physical to make up for a day I missed a basketball work out. As the second and third day came around and I was working out but there was still time to spare I started to just think, I just walked along the bay and found a nice stop and for an hour or two just......

When I walk in she hands me a paper and says chair number 12 as she rolls her eyes and walks away. I hurry up and grab my chair as soon I get to sit down BAM I fall straight on my butt …….moment of silence then all of a sudden a burst of laughter I get up and the teacher says are you ok I said yes and she says good now don’t let it happen again. I sit down and immediately put my head down and waited to the bell rang I got up threw my paper on Mrs. Rein’s desk and dash out the room. I stayed in the bathroom until it was time to go.

...change? “By compassion we make others' misery our own, and so, by relieving them, we relieve ourselves also.” In On Compassion by Barbara Lazer Ascher, Ascher recalls a couple of brief encounters with homeless people in New York City that ultimately inform her view on compassion. She wants the readers to think about how we treat others and compare ourselves to the woman with the baby and the homeless man. Asking ourselves if the things we are doing is out of fear or compassion. Sometimes I wonder if what I did back in New York was out of compassion or pity. When I was little I remember my family taking me to New York City for a Christmas vacation. It was during that time when the snow was falling and the wind was blowing heavily. We were walking down the streets towards the big Christmas tree, but then I noticed an old man sitting down next to a fountain near a business building, with a sign up that said “Change please?” He was wearing a ragged demi jacket, black gloves, loosely jeans, a small wool hat, and a pair of Nike sneakers. However, people didn’t seem to notice him as they walk pass him nor look at the sign at all. Feeling sadden by this I pulled out my twenty dollar bill from my coat pocket that I was saving and walked up to the man, I hold out the twenty to him and said “A Christmas present for you sir.” The man looks up at me, took the twenty, and said “Bless you child!” with a joyful smile on his face. Seeing his smile made me feel good about myself, that I did......
