“Kuantum Kuşakları muhteşem bir başarı. Kragh fizik-teknoloji arayüzündeki gelişmelere de yer vermiş ve böylece yirminci yüzyıl fiziğinin alışılmadık derecede kapsamlı ve dengeli bir açıklamasını yapmış. Aynı derecede etkileyici olan şey ise kitabın genel okur tarafından kolayca erişilebilir olması ve bilim insanları ve tarihçiler tarafından da değerlendirilecek olmasıdır.” –S.S. Schweber
“Kuantum Kuşakları, 20. yüzyıl fiziğini tam olarak anlamak isteyenler için vazgeçilmez bir referans.” –Spencer R. Weart, Amerikan Fizik Enstitüsü
“Kragh, 20. yüzyıl fiziğinin gelişiminin ilgi çekici ve kapsamlı tarihini kolayca erişebilecek bir şekilde sunmuş.” –Ronald Anderson, Boston College
“20. yüzyıl fizik tarihinin her bir öğesi için mükemmel bir rehber.” –Laurie M. Brown, Physics Today “Bilimsel çalışma sürecini anlayan biri tarafından yazılmış çok iyi bir bilim tarihi. Kuantum Kuşakları bilimin gerçekte nasıl işlediğine ilgi duyan herkese hitap edecektir.”
–D.R. Matravers, Contemporary Physics“Ne kadar okunabilir ne kadar değerli bir kitap.” –Graham Farmelo, Nature
Helge Stjernholm Kragh is a Danish historian of science. Kragh studied mathematics and physics at the University of Copenhagen before obtaining his PhD in 1981 at the University of Roskilde. He is a professor at the Centre for Science Studies of Aarhus University.
Kragh's areas of study are the history of physics from the mid-19th century onward, the history of astronomy, the history of cosmology and the history of chemistry.
After reading three of Kragh's books (Cosmology and Controversy [1996], Conceptions of Cosmos [2006] and Higher Speculations [2011]) I decided to read one more - and I am glad I did. Whereas in the earlier mentioned books Kragh delves deeply into science and writes books of 300-400+ pages on just a few topics, Quantum Generations is a much more accessible book. In essence, it's a book about the developments in physical science in the 20th century.
Written in 1997-1999, the book is a little outdated on some topics (such as cosmology), but it gives the reader a comprehensive - and comprehensible! - overview of physics. Each chapter is about 15 pages long and deals with a specific topic, which is a welcome change (in most of his other books, Kragh writes very long and dense chapters of 40+ pages long). Kragh gives detailed explanations about the scientific theories themselves, but also discusses topics such as the militarization of physics after World War II, socio-cultural attitudes towards science, the scientific method as such (and philosophy of science).
The only downside of this book is that some chapters are extremely accessible, and some other chapters - especially towards the end of the book; dealing with high energy physics and grand unification theories - require much more prior knowledge about the respective topics. Kragh could have offered a little bit more background information on topics such as the discovery of new fundamental particles, the development of the weak electromagnetic theory and the gauge field theories of strong interactions. Nevertheless, this was a delightful book to read and helps tremendously to put more basic knowledge of physics in a bigger perspective.
The history of Physics is fraught with twists and turns, stops and starts. This is especially true of the 20th century. At the beginning of that time, scientists publicly announced that nothing major was left to discover in Physics, the only things left to cover were tiny details to fill in. Our knowledge of the universe would be complete.
We know looking back how that turned out, X-Rays were discovered, Blackbody Radiation was explained through quantum effects, Relativity came into vogue, and so on. In fact, so many significant events happened in the 20th century that the author informs us at the preface that this book doesn’t do it justice.
Quantum Generations by Helge Kragh is the book that discusses all of this and more. It talks about the state of physics at the turn of the century. For instance, who was your average physicist? What philosophies did they embrace? How did they view the world in general? What paradigms did they espouse? It makes for rather fascinating reading, to be honest. I mean, Kragh even provides demographic information. Although he states that a lot of the information is scanty and inadequately covers a lot of detail, I believe it does a good job.
The book is divided into three main sections by chronology. The first one covers the period of time from the discovery of x-rays up to the end of World War I. The second section covers the period of time up until the end of World War II. The third section covers the remainder of the century up to around 1998 or so.
The book is really good, the only fault I have against it is the lack of images. There are a lot of graphs and tables of demographic data, but no pictures. Honestly, that is the only complaint I have against this book.
An excellent academic overview of the history of 20th century physics. Kragh's book is notable for its depth, the fact that it takes great pains to be international in its coverage, and because the narrative it puts forward is an even mix of factual information and discussion of historical/methodological/interpretive disputes (of which there are many in the history of physics). As such it distinguishes itself greatly from practically all popular histories of physics, being much more in tune with the questions that academic historians of physics are interested in, and a much richer text as a result.
Generaciones cuánticas esboza en gran medida el desarrollo de la física en el siglo pasado, los diferemtes capítulos abordan las diferentes ramas de la física que nacieron o tuvieron desarrollos importantes, esta narrativa sigue los diferentes cambios de paradigma que llevaron a grandes fisicos a postular teorías, desarrollar experimentos y realizar hallazgos de suma importancia. A su vez, analiza los diversos factores sociales y geopolíticos que impulsaron varios avances científicos. Personalmente, considero que es un libro bastante enriquecedor para personas que están interesadas en la física y buscan un campo de investigación cuando no es muy claro el trabajo que se realiza y las fuertes implicaciones que estos tienen.
Además, podria decir que es un texto medianamente accesible, si bien, no es imperativo tener un dominio notable de los temas, si es recomendable tener cierto conocimiento de física, el texto prescinde de ecuaciones y las gráficas aluden más al panorama educativo, producción de artículos, inversiones e ingresos. Sin embargo, la descripción de experimentos y la contraposición de paradigmas a través del tiempo exige un cierto grado de conocimiento o familiaridad con la física. Buen libro.
Best history that's been written to date of the development of modern physics from the late 19th century to now. Every physicist, student of physics, or student of the epistemology of science, should read it.
