Approximation Methods in Science and Engineering

Approximation Methods in Science and Engineering
Reza N. Jazar, "Approximation Methods in Science and Engineering"
English | 2020 | pages: 544 | ISBN: 1071604783 | PDF | 7,1 mb
Approximation Methods in Engineering and Science covers fundamental and advanced topics in three areas: Dimensional Analysis, Continued Fractions, and Stability Analysis of the Mathieu Differential Equation. Throughout the book, a strong emphasis is given to concepts and methods used in everyday calculations. Dimensional analysis is a crucial need for every engineer and scientist to be able to do experiments on scaled models and use the results in real world applications. Knowing that most nonlinear equations have no analytic solution, the power series solution is assumed to be the first approach to derive an approximate solution. However, this book will show the advantages of continued fractions and provides a systematic method to develop better approximate solutions in continued fractions. It also shows the importance of determining stability chart of the Mathieu equation and reviews and compares several approximate methods for that. The book provides the energy-rate method to study the stability of parametric differential equations that generates much better approximate solutions.

Apocalyptic Anxiety Religion, Science, and America's Obsession with the End of the World

Apocalyptic Anxiety Religion, Science, and America's Obsession with the End of the World
Anthony Aveni, "Apocalyptic Anxiety: Religion, Science, and America's Obsession with the End of the World"
English | 2016 | pages: 276 | ISBN: 1607324709 | PDF | 3,3 mb
Apocalyptic Anxiety traces the sources of American culture's obsession with predicting and preparing for the apocalypse. Author Anthony Aveni explores why Americans take millennial claims seriously, where and how end-of-the-world predictions emerge, how they develop within a broader historical framework, and what we can learn from doomsday predictions of the past.

Anthem for Doomed Youth twelve soldier poets of the First World War

Anthem for Doomed Youth twelve soldier poets of the First World War
Jon Stallworthy, "Anthem for Doomed Youth: twelve soldier poets of the First World War"
English | 2005 | ISBN: 1845292219 | EPUB | pages: 192 | 47.9 mb
Leading poet and former professor of English Literature, Jon Stallworthy, tells the story of the lives and work of twelve major poets of the First World War and provides selections of their best work. The First World War began with flag-waving, parades and poets inspired by abstract ideals. In part this reflected the national mood , but it revealed an almost universal failure to understand what modern mass warfare would really mean. The story of the 'war poets' is also the story of an awakening to the full horror of what the twentieth century came to know as 'The Great War'. Wilfred Owen said, 'My subject is War - and the pity of War'. He also said 'true Poets must be truthful'. The best war poetry was the work of writers who were also serving soldiers and was born out of their desire to tell the truth about what it was to be a soldier in the trenches - what it felt like, what it did to you and what it did to your fellow soldiers, friend or foe. The greatness of the poetry lay not just in the writer's talent, but in the unflinching accuracy with which it portrayed their terrible circumstances.
