  By many expert mathematicians, group theory is often addressed as a central part of mathematics. It finds its origins in geometry, since geometry describes groups in a detailed manner. The theory of polynomial equations also describes the procedure and principals of associating a finite group with any polynomial equation. This association is done in such a way that makes the group to encode information that can be used to solve the equations. This equation theory was developed by Galois. Finite group theory faced a number of changes in near past times as a result of classification of finite simple groups. The most important theorem when practicing group theory is theorem by Jordan holder. This theorem shows how any finite group is a combination of multiple finite simple groups. 
  Group theory is a term that is mainly used fields related to mathematics such as algebraic calculations. In abstract algebra, groups are referred as algebraic structures. Other terms of algebraic theories, such as rings, fields and vector spaces are also seen as group. Of course with some additional operations and axioms, mathematicians accept them as a group. The methods and procedures of group theory effect many parts and concepts of mathematics as well as algebra on a large scale. Linear algebraic groups and lie groups are two main branches or say categories of group theory that have advanced enough to be considered as a subject in their own perspectives. 
  Not only mathematics, group theory also finds its roots in various physical systems, especially in crystals and hydrogen atom. They might be modeled by symmetry groups. Thus it can be said that group theory possess close relations with representation theory. Principals and ideas of group theory are practically applied in the fields of physic, material science and chemistry of course. Group theory is also considered as a central key in the studies and practices of cryptography. In 2000s, more than 10000 pages were published in the time span of 1960 to 1980. These publications were a collaborative effort in order to culminating the result as a complete classification of infinite simple groups. For the practitioners and learners of mathematics or even physics the theory of groups has a great importance. Not all aspects of this theory are used in mathematics or physics. But there are some ideas and principals that help a lot as you advance to higher level mathematics, it is very same with the physics. Full application of this wide theory is not possible on a single subject anyhow. However it is partially applied in both cases, and still leaves a great influence.

  When we talk about technology we always talk about tomorrow and the future - which makes it hard to figure out how to even get there. In Future Histories, public interest lawyer and digital specialist Lizzie O'Shea argues that we need to stop looking forward and start looking backwards. Weaving together histories of computing and progressive social movements with modern theories of the mind, society, and self, O'Shea constructs a "usable past" that can help us determine our digital future.
   
  What, she asks, can the Paris Commune tell us about earlier experiments in sharing resources - like the internet - in common? How can Frantz Fanon's theories of anti-colonial self-determination help us build a digital world in which everyone can participate equally? Can debates over equal digital access be helped by American revolutionary Tom Paine's theories of democratic, economic redistribution? What can indigenous land struggles teach us about stewarding our digital climate? And, how is Elon Musk not a future visionary but a steampunk throwback to Victorian-era technological utopians?
   
  In engaging, sparkling prose, O'Shea shows us how very human our understanding of technology is, and how when we draw on the resources of the past, we can see the potential for struggle, for liberation, for art, and poetry in our technological present.

  A Railway History of New Shildon...

  An “extraordinarily informative and profusely illustrated” history of how a town built a railway, and a railway built a town (Midwest Book Review).   On September 27, 1825, the first public railway steam train left New Shildon for Stockton-on-Tees, England. The driver was George Stephenson and the engine he was driving was the “Locomotion No.1.” It set off from a settlement that consisted of just a set of rails and four houses, none of which had been there a year before. The four houses became a town with a five-figure population, a town that owed its existence to the railway that made its home there—the Stockton and Darlington (S&DR).   Some of the earliest and greatest railway pioneers worked there, including George and his son Robert; the Hackworth brothers, Timothy and Thomas; and the engineer William Bouch. Their story is part of New Shildon’s story. The locomotive works, created to build and maintain steam locomotives, morphed into the world’s most innovative works, whose demise had more to do with politics than productivity. This book covers Shildon’s years between 1820 and today, including the war interludes when the Wagon Works was manned by women and the output was mostly intended for the Ministry of Defense. The story of the creation of the town’s railway museum and the arrival of Hitachi at Newton Aycliffe brings the history up to date and, to complete the picture, there is also a description of the ongoing new build G5 steam locomotive project on Hackworth Industrial Estate, the very site where the S&DR locomotive and wagon works was located. It is the story of a railway town—and also the story of the people who lived there and made it what it is today.

  This program is read by the author."As a mature observer of the human condition, Marsh has audible serenity that makes listeners curious about how his story ends." - AudioFile MagazineFrom the bestselling neurosurgeon and author of Do No Harm, comes Henry Marsh's And Finally, an unflinching and deeply personal exploration of death, life and neuroscience.As a retired brain surgeon, Henry Marsh thought he understood illness, but he was unprepared for the impact of his diagnosis of advanced cancer. And Finally explores what happens when someone who has spent a lifetime on the frontline of life and death finds himself contemplating what might be his own death sentence.As he navigates the bewildering transition from doctor to patient, he is haunted by past failures and projects yet to be completed, and frustrated by the inconveniences of illness and old age. But he is also more entranced than ever by the mysteries of science and the brain, the beauty of the natural world and his love for his family. Elegiac, candid, luminous and poignant, And Finally is ultimately not so much an audiobook about death, but an audiobook about life and what matters in the end. A Macmillan Audio production from St. Martin’s Press.

  Preventing the Next Pandemic

  The last five years saw a significant return of epidemic infectious disease, culminating in COVID-19. In our new post–COVID-19 world, how do we prevent future illnesses by expanding scientific and vaccine diplomacy and cooperation, especially to combat the problems that humans have brought on ourselves?Modern diseases and viruses have been spurred anew by war and conflict as well as shifting poverty, urbanization, climate change, and a new troubling antiscience/anti-vaccination outlook. From such twenty-first-century forces, we have seen declines in previous global health gains, with sharp increases in vaccinepreventable and neglected diseases on the Arabian Peninsula, in Venezuela, in parts of Africa, and even on the Gulf Coast of the United States. In Preventing the Next Pandemic, international vaccine scientist and tropical disease and coronavirus expert Peter J. Hotez, MD, PhD, argues that we can—and must—rely on vaccine diplomacy to address this new world order in disease and global health. Detailing his years in the lab developing new vaccines, Hotez also recounts his travels around the world to shape vaccine partnerships with people in countries both rich and poor in an attempt to head off major health problems. Building on the legacy of Dr. Albert Sabin, who developed the oral polio vaccine with Soviet scientists at the height of the Cold War, he explains how he is still working to refresh and redirect vaccine diplomacy toward neglected and newly emerging diseases.Hotez reveals how—during his Obama-era tenure as the US Science Envoy for the Middle East and North Africa, which coincided with both the rise in these geopolitical forces and climate change—he witnessed tropical infectious diseases and established vaccine partnerships that may still combat them up close. He explores why, since 2015, we've seen the decline of global cooperation and cohesion, to the detriment of those programs that are meant to benefit the most vulnerable people in the world. Unfortunately, Hotez asserts, these negative global events kick off a never-ending loop. Problems in a country may lead to disease outbreaks, but those outbreaks can lead to further problems—such as the impact of coronavirus on China's society and economy, which has been felt around the globe. Zeroing in on the sociopolitical and environmental factors that drive our most controversial and pressing global health concerns, Hotez proposes historically proven methods to soothe fraught international relations while preparing us for a safer, healthier future. He hammers home the importance of public engagement to communicate the urgency of embracing science during troubled times.Touching on a range of disease, from leishmaniasis, schistosomiasis, and Middle East Respiratory Syndrome (MERS) to COVID-19, Preventing the Next Pandemic has always been a timely goal, but it will be even more important in a COVID and post-COVID world.
