Other examples that they recorded included $13^2=5^2+12^2$ and even $8161^2=4961^2+6480^2$. One of the great intellectual masterpieces of the ancient Greek world was Diophantus' {\sl Arithmetic}. This work, available in Latin translation in the seveteenth century, was an important inspiration for the scientific renaissance of that period, read by Fermat, Descartes, Newton and others. Fermat, a jurist from Toulouse, studied mathematics as a hobby. He didn't formally publish his work but rather disseminated his ideas in letters, challenging
The History of the Calculus The Calculus, being a difficult subject requires much more than the intuition and genius of one man. It took the work and ideas of many great men to establish the advanced concepts now known as calculus. The history of the Calculus can be traced back to c. 1820 BC to the Egyptian Moscow papyrus, in which an Egyptian successfully calculated the volume of a pyramidal frustum. [1][2] Calculating volumes and areas, the basic function of integral calculus, can be traced back from the school of Greek mathematics, Eudoxus (c. 408−355 BC) used the method of exhaustion, which prefigures the concept of the limit, to calculate areas and volumes while Archimedes (c. 287−212 BC) developed this idea further, inventing heuristics which resemble integral calculus. [3] The method of exhaustion was later used in China by Liu Hui in the 3rd century AD in order to find the area of a circle.
Jordan N. Gibson September 4, 2011 CEE 2804 Writing Assignment #1 The Galloping Gertie One of the most widely studied failures in the history of engineering, the Tacoma Narrows Bridge is a staple in every physics and engineering textbook across the board. From its humble beginnings in September 1938, it took only nineteen months to construct the third largest suspension span bridge in the world of its time. However, it took a mere four months to fall (Big Tacoma). Designed by one of the world’s foremost bridge engineers and top-ranked engineering consultants, Leon Moisseiff, how could such a spectacular structure fall? After numerous investigations were completed, it was discovered the collapse of the Tacoma Narrows Bridge was due to a combination of: a misconception of extreme flexibility of the structure, use of more economical but weaker materials, and the lack of realization of the strength of aerodynamic forces.
A summary of Alfred Adler’s Biography Psychology is the scientific study of behavior and mental process. In fact psychology is a very big field, and is filled with a lot of psychologists who have their own perspectives about how the human brain works. Alfred Adler a very outgoing, popular and an involved scholar, was born on February 7, 1870 in the suburbs of Vienna, had a very rough childhood, in which he couldn’t walk until the age of four and he was diagnosed with pneumonia that almost killed him. These horrific events inspired him to be a physician and they could be the reason behind his big achievements during his lifetime. Thus, Alfred Alder received his medical degree from the university of Vienna in 1895 and got married in 1897 to a Russian intellectual and social activist whom he met during his university years.
A Beautiful Mind by Sylvia Nasar ‘A tale of how a man achieved the Nobel Prize after 10 years of schizophrenia’ Set during the 20th century, A Beautiful Mind is a biography on John Nash, whom worked against all odds and achieved the Nobel Prize for Economical Science in 1994 after been diagnosis of schizophrenia in 1959. ‘How could you, a mathematician, believe that the extraterrestrials were sending you a message?’ a Harvard visitor asked. ‘Because the ideas I had about supernatural beings came to me the same way my mathematics ideas did, and I took them seriously!’ came the answer. Thus begins the tale of John Nash, a mathematician who suffered from schizophrenia at the ago of 30, and who—with the selflessness of his family members and the faithfulness of Princeton—emerged as one of the most famous and influential mathematician on the century, also holder of the Nobel Prize for economics for 1994. Nash was born in Bluefield on 23rd June 1928, from young; Nash can be seen as a unique child.
But the most important contribution Descartes made were his philosophical writings; Descartes, who was convinced that science and mathematics could be used to explain everything in nature, was the first to describe the physical universe in terms of matter and motion, seeing the universe as a giant mathematically designed engine. Descartes wrote three important texts: Discourse on the Method of Rightly Conducting the Reason and Seeking Truth in the Sciences, Meditations on First Philosophy, and Principles of Philosophy. René Descartes had always been a frail individual, and he would usually spend most of his mornings in bed, where he did most of his thinking, fresh from dreams in which he often had his revelations. In his later years, Descartes had to relocate to Sweden to tutor Queen Christina in philosophy.
Einstein had some difficulty finding a job but he later found a job to work as a patent Clerk, He later Lectured at many Universities. He found a breakthrough through his publication in 1905. What were Einstein's inventions and contributions to the society? Einstein invented the television which is found in every home now and which is the most used device nowadays and people can not even live without watching tv now. It has become a very important part of every home thanks to Einstein.
A Brief History of Time - Stephen Hawking Written by one of the greatest minds of this century, A Brief History of Time covers the most revolutionary scientists since 340 BC in the fields of subatomic particle physics, theoretical physics, and astrophysics. The subjects of of quantum physics and general relativity are also brought up later in the book as Hawking moves into the subject of the Theory of Everything, or quantum relativity, and the struggles scientists, including Hawking, have gone through to try to understand this and make it into a unified theory. Lastly, Hawking also covers the miraculous four-dimensional spacetime and the scientists who have impacted the field, like Albert Einstein and James Maxwell, throughout the past two centuries to help shape what we now call theoretical particle physics. 340 BC, a greek philosopher by the name of Aristotle began curiously exploring the heavens in a search for an explanation as to what was out there. Aristotle wrote the book On the Heavens that covered two main arguments.
Pascal decided to learn about geometry, a topic he had only heard of but never studied, in his spare time. By age thirteen, he had proven the 32nd proposition of Euclid and discovered an error in Rene Descartes geometry. His father put Pascal’s knowledge in mathematics towards hand totaling long columns of numbers to his job. Pascal later went on the create the pascaline, a device fourteen by five by three inches that could do calculations, which can now be considered the first mechanical calculator. In 1650, Pascal suddenly decided to avidly study religion, but returned to his previous lifestyle three years later, conducting experiments on the pressure exerted by gases and liquids, inventing the arithmetical triangle, and created the calculus of probabilities together with Fermat.
Chapter 5: Gann’s Theory William Delbert Gann (1878-1955) was a legendary trader who wrote a number of books on technical analysis. His theory is based on geometry, astrology, mathematical principles, and the natural laws of cycles. Gann introduced the use of angles in the stock market in The Basis of My Forecasting Method (1935). However, application of Gann’s angle is a major task, and opinions are sharply divided on the value of his work. In his last book 45 Years in Wall Street (1949), he highlighted and defended his trading rules and techniques.
