Isaac Newton by James Gleick | Review
Isaac Newton by James Gleick | Review Trusha Patel Isaac Newton by James Gleick Opinion Isaac Newton was the most famous scientist of his generation and one of the most recognizable physicists of all time. He accomplished amazing feats; he ââ¬Å"pushed open a door that led to a new universeâ⬠(8). Some of his major achievements include the application of the law of gravity to the motion of planets, the path of comets, and the influence of the moon on ocean tides. Gleickââ¬â¢s biography attempts to clearly portray for the reader the entirety of Newtonââ¬â¢s life ââ¬â his successes, his shortcomings, his obsession with both science and the non-scientific, and his good as well as bad mixture of qualities. Gleick successfully presents Newtons life about as well as one could conceive it being presented in 191 pages. One of Gleickââ¬â¢s greatest successes is his emphasis on Newtonââ¬â¢s true characteristics. Students are taught that Newton was some sagacious man who believed in the welfare of humanity. Gleick, on the other hand, portrays Newton as how he thought Newton truly was: solitary, selfish, and paranoid even though he was extremely brilliant. The author states, ââ¬Å"Isaac Newton said he had seen farther by standing on the shoulders of giants, but he did not believe it. He was born into a world of darkness, obscurity, and magic; led a strangely pure and obsessive life, lacking parents, lovers, and friends; quarreled bitterly with great men crossed his path; veered at least once to the brink of madnessâ⬠¦and yet discovered more the of the essential core of human knowledge than anyone before or afterâ⬠(3). These insightful descriptions of Newtonââ¬â¢s state of mind widen the readerââ¬â¢s perspective on his life. They make the reader think of Newton beyond his scientif ic thoughts. Gleick describes Newtonââ¬â¢s scientific and non-scientific pursuits. He specifically points out that Newton did not discover the entirety of motion with the falling of the apple. It took a long time with complex thinking and developments before Newton theorized gravitation. Newton had spent time learning about other concepts like optics as well. The author also sheds light on Newtonââ¬â¢s obsession with the occult alchemy as well as with his repudiation of Trinitarianism. Furthermore, Gleick mentions Newtonââ¬â¢s participation in Parliament and his control of the British mint. These actions help the reader understand Newtonââ¬â¢s motivations. Gleick also does not refine the language from back in the day to make it modernized. Instead, he presents quotations in the original English from which they came. This becomes increasingly important when readers reach the section on the Principia because it would greatly connect to their physics studies if they were to read the original form of Newtonââ¬â¢s laws and their implications. Gleick quotes, ââ¬Å"Absolute, true, and mathematical time, in and of itself, and of its own natureâ⬠¦flows uniformlyâ⬠(125). Gleick portrays Newtonââ¬â¢s standardization of the term time. Through reading the seventeenth century language, science students become aware of the importance of precise language in physics. Gleickââ¬â¢s biography provides a complete portrayal of Newton from his peculiarities to his perseverance. The reader can readily perceive the change that occurred after Newtonââ¬â¢s renovation of science. Gleick tells the reader, ââ¬Å"What Newton learned remains the essence of what we knowâ⬠¦We are Newtoniansâ⬠(6). Through this book, we learn the origin of Newtonââ¬â¢s thoughts which led to such a revolution in scientific thought. Biographical Analysis Newtonââ¬â¢s life was shaped significantly by the world he lived in, and this molded the science that was churned out of his brilliant mind. Newton was born in the Woolsthorpe farm in England. Newtonââ¬â¢s mother was widowed when Newton was only three years old. She married the wealthy Barnabas Smith, who did not want any kids. Newton ended up being raised by his grandmother. He grew up to be a shy schoolboy; ââ¬Å"he was small, lonely, and abandonedâ⬠(11). Newtonââ¬â¢s solitude would later lead to his incredible theories of the natural world. As a young boy, Newton spent his time learning about the workings of sundials and the movement of the night sky, noting observations that would later lead to his theory of gravitation. When Newtonââ¬â¢s step-father died, his mother Hannah returned and sent the ten-year-old Newton to another school. In Newtonââ¬â¢s new school, he was taught Latin and mathematics by Henry Stokes. He lived with the apothecary Clarke who furthered his scientific curiosity. All of these things along with his personal studies of light were inscribed in a notebook. Newton had learned the roots of scientific inquiry at an early age: he was classifying and analyzing at a very young age. When Newton was sixteen, his mother called him home to be a farmer, but he failed. As a result, Newton attended the prestigious University of Cambridge in Trinity College where he would later become famous. During his first three years at Cambridge, Newton was taught the standard curriculum but was fascinated with the more advanced science. All his spare time was spent reading from the modern philosophers. Even though he was a top student, Newton was reprimanded for religious negligence in a remarkably Anglican institution. Newton studied the Aristotelian worldview in which a force was necessary to keep an object in motion. He absorbed himself in the Trinity College library and ââ¬Å"found his way to new ideas and polemics: from the French philosopher Renà © Descartes, and the Italian astronomer Galileo Galileiâ⬠(25). Both philosophers defied Aristotle explicitly; Descartes proposed geometrical and mechanical philosophy, while Galileo claimed that all bodies are made of the same stuff, which is heavy, and therefore fall at the same rate. In Newtonââ¬â¢s second year, he started a new section about philosophical questions he had. The first was if atoms exist. Was matter continuous and infinitely divisible, or discontinuous and discrete? Is space finite or infinite? What is the nature of motion and light? Why do objects fall? From matter to motion, to light, to the structure of cosmos, Newton had ideas about everything. Newton concluded that force causes motion. He also occupied himself with the concepts sound, memory, magnetism, heat, and the tides. In 1664, Newton learned about Euclidââ¬â¢s Elements, from Cambridge Universityââ¬â¢s first professor of mathematics, Isaac Barrow. Unfortunately, in 1665, the Great Plague that was ravaging Europe had come to Cambridge, forcing the university to close. Newton was sent home but he still constantly had his attention focused on mathematics. Gleick writes, ââ¬Å"he computed obsessivelyâ⬠¦ to conceive of infinite series and then learn to manipulate them was to transform the state of mathematicsâ⬠(39). Newton formulated the Binomial theorem in the same year. It was a method to expand a sum to any power. Furthermore, Newton began to discover a method to determine the slope of a tangent line to a curve, which we call the ââ¬Å"derivative.â⬠Newtonââ¬â¢s concern with all of this would become the foundation for calculus and physics. He chose not to publish, and decided to keep to himself. In 1666, Newton was trying to figure out how the attractive power between masses would diminish, and he learned that it lessens with the square of the distance. He questioned the movement of celestial bodies, such as the moon and earth wondering why they proceeded in a circular path. He needed precise terminology with definite units to facilitate his hypotheses, but ââ¬Å"Writing in English, he was constrained by the language at handâ⬠(59). The imprecise language was not sufficient enough to describe motion. Newton also explored optics and experiment with prisms. When the plague subsided in 1667, Newton returned to Cambridge. Newton and Barrow attacked the subject of cubic equations. He tried to sort all the curves into different groups. Barrow showed him a book by Nicholas Mercator called Logarithmotechnia. Mercator had a method of calculating logarithms from infinite series and this discovery shocked Newton. So Newton wrote a paper called ââ¬Å"On Analysis by Infinite Seriesâ⬠and gave it to Barrow to post this to another Royal Society colleague. Although he wanted anonymity, his name was revealed. ââ¬Å"It was the first transmission of Newtonââ¬â¢s name south of Cambridgeâ⬠(68). Even though Newton preferred solitude, people began to recognize his mathematical expertise. When Barrow retired, Newton took the position of the Lucasian Professor at the age of twenty-seven. Newton lectured his students on the mathematics of light refraction ââ¬Å"with none of the romance or metaphor that usually ornamented the philosophy of ligh tâ⬠(71). The invention of telescopes had spurred intense interest in the properties of light. He then realized that the common refracting telescopes were inferior to reflecting telescopes because the seven colors of light created glare, so he spent a lot of his time constructing a powerful reflecting telescope, which Barrow gave to the Royal Society after two years. Soon after, Secretary Oldenburg urged Newton to let the Royal Society publish his findings on the reflecting telescope. He made Newton think foreigners might steal his ideas, so Newton became a member of the Royal Society. Newton wrote to Oldenburg that within three years, he would make a great philosophical discovery, and then he would formally join. His focus was optics at this time. He wrote to Oldenburg that white light was composed of seven colors as evidenced by the prism experiments. By now, Newtonââ¬â¢s rivalry with Robert Hooke grew strong as Hooke proposed a wave theory of light, whereas Newton promoted a corpuscular theory. Not only Hooke, but also Huygens, ââ¬Å"the great Dutch mathematician and astronomer, also favored the wave theory of lightâ⬠(88). Newton became frustrated because he attempted to show that the particle nature of light followed from mathematics, whereas the others contended that this was wishful thinking on Newtonââ¬â¢s part. Hooke and Newt on lashed at each other, claiming that the other was guilty of plagiarism. Oldenburg was adding to his paranoia; he used the discoveries of foreigners such as Wilhelm Gottfried Leibniz to make Newton reveal more and more of his secret studies, until Newton finally stopped all communication for two years. Around 1675, Oldenburg died and Hooke became the secretary of the Royal Society. Newtonââ¬â¢s fears grew. Newton had another disagreement with Hooke over the relationship between orbits and falling objects. They were explaining the planetââ¬â¢s motion and both had come to believe in a bodyââ¬â¢s inherent force. Hooke proposed an inverse square explanation for elliptical orbits, and Newton possessed the mathematical ability to explain this. At this Hooke, ââ¬Å"acknowledged Newtonââ¬â¢s superior powersâ⬠(121). In 1684, astronomer Edmond Halley posed the question to Newton of elliptical orbits implying an inverse square relationship between gravity and distance. Newton sent him what he had already finished, but to continue, Newton needed to standardize the definitions of space and time. Such standardization led to Newtonââ¬â¢s Philosophiae Naturalis Principia Mathematica. The totality of Newtonââ¬â¢s studies of motion was in three volumes, with the only assumption being a gravitational force that diminishes with the square of the distance. His famous three laws of motion were in Principia: that an object in motion remains in motion unless acted upon by a net force, an object accelerates in the direction of that force, and if two bodies exert a force on one another, the forces are equal in magnitude, but opposite in direction. In Newtonââ¬â¢s later years, he attempted to calculate the position of the moon. He then became the member of Parliament as well as Warden of the British mint. Following Hookeââ¬â¢s death, Newton became the President of the Royal Society as well as published Opticks, a piece on his experiments with light. On March 20, 1727, Newton died of a stone in his bladder. Newtonianism had profound influences on the world. His achievements revolutionized physics and mathematics and he has been recognized as an undisputed genius. Newtonââ¬â¢s years of hard work resulted in a successfully description of this world. He played a major role in the advancement of the scientific community of his time and of today. Are Vitamin Supplements Effective? Are Vitamin Supplements Effective? Vitamins are organic compounds that are required in very little amounts for us to grow and live in and maintain good health, although they are a critical requirement for our body in order to survive; they are not compulsory but vitally important, According to Stanton, [1] implied[s] amine meaning life. But an inadequate amount of vitamin may cause disease and in some cases are highly detrimental. Vitamins help to protect against many diseases, it is estimated that theres 13 essentials vitamins which 4 is classified as fat-soluble (A, D, E and K) and 9 as water-soluble (8 Vitamin B and Vitamin C). The vitamins that are fat soluble are hydrophobic which ultimately to be soluble in fats; the fat globules (referred as chylomicrons) which are consistently absorbing this vitamins, that travels the lymphatic system of the small intestines and into the general blood circulation within the body. These vitamins are proclaimed as Vitamin E and A which then is stored in the tissue. Where in star k contrast the water-soluble are required as enzymes cofactors in a much wider variety of metabolic reactions, each of this water soluble vitamin are often seen to have its own membrane transport to help it process for absorption across enterocyte. [4] Vitamins are found in its natural forms are meat, fruit, dairy, vegetables and many other substances, but an advancement of science, scientist has revealed an alternative pathway for those who can take their vitamins in a form of tablets, gums, drops and capsules. This has been mixed with many other forms of compounds which include trace elements, electrolytes, spinach and/or broccoli extract. Not being able to undertake the recommended dosage of vitamins can lead to serious disease. There is a strong correlation between the rates of chronic disease and the increase level of vitamin D. The most common disease which has a strong positive relationship is rickets; which often can be reduced or cured by undertaking liver oil during the 20th century. Rickets cause weakens and soften the bones in children which could impact in skeletal abnormalities, defective growth, delicate bones and dental problems. While in adults, the deficiency of vitamin D can lead to osteomalacia and osteoporosis which weaken the bones. [4]. the insufficiency of any form of vitamins can have led to a serious health issue from CVD (cardiovascular disease),[3] Alzheimers [4] fat malabsorption, immunity, stomach and many more. [3]. by undertaking vitamins in its natural form (food; vegetables, fruits, dairy, meat etc.) it can help to limit the possibility of overdosing. Although theres a series of experime nts that has been conducted theres no ultimate answer that antioxidants helps to decrease or remove the risk of diseases such as CVD. [4] Both increase and decrease of vitamins can lead to health problems; possibly overdosing in vitamin supplement such as B3 may potentially lead to nausea, liver/nerve toxicity and jaundice. Dr. Weil [5] specifically states that most customers or patients often take supplements as they have just heard it advertised. An excessive amount of iron supplements can lead to risk of cancer and heart disease, as iron is an oxidizing agent [5] Although vitamins have contributed as an alternative for those who cant consume it natural forms, the epidemiological studies has concluded that those whose diet are high in vegetable consumption may lower the incidence of cancer and other vitamin deficiency, this helps to decrease the expenditure of meat and feat while increasing the dosage of fiber content. [2]. However some research has proven that Vitamin E supplementation helps to lower the CVD; but generally this is often reflected in an individuals lifestyle. [6][4]. There is several of data that demonstrate that vitamin supplementation on regular basis did not justify the routine of antioxidant supplements for the preventive and treatment of CVD or lowering it. [8] Supplementation carries out several of chemicals that may trigger the mind and the body of an individual which can have a detrimental effect on them. Based on several experiments it is evaluated that vitamins contain a vegetable extract and other compounds such as having an adverse effect and may interact with warfarin and aluminum. [9]. There is significant amount of data, experiment that analysis that justifies that using antioxidant vitamin supplements for CVD, and other disease does not necessarily reduces the risk of reduction. A great healthy lifestyle by consuming the right amount of vegetable and fruits will help decrease the risk of immune deficiency etc. Multi-vitamins can be used as an alternative pathway for those who are not able to consume them, but should not be used on regular basis which is a dangerous practice.
