Pi has always been an interesting concept to me. A number that is infinitely being calculated seems almost unbelievable. This number has perplexed many for years and years‚ yet it is such an essential part of many peoples lives. It has become such a popular phenomenon that there is even a day named after it‚ March 14th (3/14) of every year! It is used to find the area or perimeter of circles‚ and used in our every day lives. Pi is used in things such as engineering and physics‚ to the ripples created

Pi is an ancient and wonderful Number to the World of Mathematics invented with the Geometrical structure Circle. CIRCLE It is felt that the creation of the Circle is not created by the man himself but came through the inspiration of Nature itself. The shape of Sun‚ Full Moon‚ Eyes are some examples for it. Some basic things : There are 3 major parts to remember. Radius : The straight line drawn to the Circumference of the Circle from the Centre

The History of Pi Throughout the history of mathematics‚ one of the most enduring challenges has been the calculation of the ratio between a circle’s circumference and diameter‚ which has come to be known by the Greek letter pi. From ancient Babylonia to the Middle Ages in Europe to the present day of supercomputers‚ mathematicians have been striving to calculate the mysterious number. They have searched for exact fractions‚ formulas‚ and‚ more recently‚ patterns in the long string of numbers

History of Pi There are many people who have discovered and proved what pi is. As time goes on people discover more and more of the seemingly random numbers. Four of the people who proved pi are the Liu Hui‚ Archimedes of Syracuse‚ James Gregory‚ and the Bible. The first proof I will be talking about is Liu Hui’s. Liu Hui was a Chinese mathematician whose method for proving pi was to find the area of a polygon inscribed in a circle. When the number of sides on the inscribed polygon increased

pyramid contain what Maslow called "deficiency needs" or "d-needs": esteem‚ friendship and love‚ security‚ and physical needs. With the exception of the lower (physiological) needs‚ if these "deficiency needs" are not met‚ the body gives no physical indication but the individual feels anxious and tense. In other words‚ the hierarchy level of need moves upward as soon as the previous level of need is satisfied. Physical needs are those that are necessary for sustaining life. These have to be met

Justin Carlton PI DAY 3/14/13 * Definition of pi: Pi is the 16th letter in the Greek alphabet. It is equal to 3.141592 when shortened‚ but never ends. * Archimedes-One of the major contributions Archimedes made to mathematics was his method for approximating the value of pi. It had long been recognized that the ratio of the circumference of a circle to its diameter was constant‚ and a number of approximations had been given up to that point in time. Archimedes was the first person

some things in the world are better off not knowing. The Allegory of the Cave written by Plato and the movie Pi by Darren Aranofsky demonstrate exactly why such goals should not be attainable. In the Allegory of the Cave‚ Plato expresses the idea of different perception of the real reality and the fear of letting go that perceived reality. The prisoners chained in a cave their whole life believe the shadows is what signifies their real world and the ultimate reality whereas one prisoner (the Philosopher)

motivation in the company cannot be overlooked. Maslow’s hierarchy of needs as one of the best-known motivational theories has been applied extensively in the management of US companies‚ and some firms from other countries; such as‚ China‚ are also utilizing Maslow’s theory in order to assist in the employee motivation. However‚ because of the invalid ordering of human needs‚ cultural diversity‚ and different levels of economy‚ Maslow’s hierarchy of needs cannot be used in current Chinese business to
