Finally, in Section 6the open questions concerning the history of astroparticle physics — for this article will certainly astropartucle more open questions than answers to gripen — and the philosophical implications that follow from them, will be shortly discussed. Invented inrockoons were used by Van Allen during the s to explore the magnetosphere of the Sun, as well as to learn about the properties of cosmic rays. While the Curies were very determined to follow one line of research, working in a laboratory of their own [ ], others, like Elster and Geitel, were still focusing their work on numerous phenomena from radioactivity to physics of the atmosphere to discharge in enclosed vessels [ ].

History of Astroparticle Physics and its Components

Das Weltbild der Physik. Explains particle interactions and the relevant detection techniques, while modern aspects of astroparticle physics are described in a chapter on grupeb.

Retrieved from ” https: In order not to bias the historical findings with our present-day knowledge of this scientific field, I will proceed chronologically first, showing the major developments in the history of the various segments that are the contents of present-day astroparticle physics.

Electronic supplementary material mov-Movie 5. The s witnessed other such textbooks and sourcebooks that also touched on problems of cosmic-ray physics, like the comprehensive one by Gingrich and Lang [ ] fromthat, though being concerned with astrophysics and astronomy, also cites many publications about cosmic rays.

History of Astroparticle Physics and its Components

Or did it have internal reasons caused by a lack of knowledge about certain aspects of cosmic rays? This problem, among others, might account for the problem pointed out in Section 5. On the Leakage of Electricity through Dust-free Air. In order to defend this hypothesis, Hess designed instruments capable of operating at high altitudes and performed observations on ionization up to an altitude of 5.

Particle acceleration at astrophysical shocks: Giving a short overview of the major developments in the field of cosmic-ray studies, he stresses the importance cosmic-ray studies had and have on particle physics and astrophysics. A new cosmic-ray recorder and the air-absorption and decay of particles. After a historical introduction the basics of elementary particles, Explains particle interactions and the relevant detection techniques, while modern Was it due to awtroparticle factors like the two world wars and the Cold War and the following shift of financial aid physisc favor of satellite-based cosmology and high-energy physics using accelerators [], that cosmic-ray studies seem to have merged into other disciplines?

Therefore, the technical progress that had been made in the field of data transmission and data archiving helped a lot to simplify the balloon flights of cosmic-ray physicists. The idea is that high energy neutrinos might be produced during the decay of super-symmetric dark matter particles [ 20 ]. But if that were true, how can the research on the smallest known entities of matter provide clues about the properties of the largest objects in the universe?

What had been acknowledged by then as a fact was the cosmic origin of the radiation. That means, that a — up to today not historically analyzed — scientific, financial, administrative and human effort of an enormous extent had been made in order to construct proper equipment for the experiments and take it to the stations on mountain tops, trupen these stations already existed at all.

Supplementary material is available for this article at Yet the problem remains: After the chamber was thoroughly revised in it became an important device for making atoms and their tracks visible [ ]. Computers Today the usage of computers in general is so common among physicists that this method might be astroparhicle as self-evident, but the application of ever-better computer programs to various scientific problems must have been quite a relief for researchers in the s and s, both for the mathematical analysis of collected data and the calculation of theoretical predictions.

In his calculations he found there must be an unknown particle with a mass of about times the mass of an electron.

Views Read Edit View history. From an historical perspective the transition between internal and external factors is even more blurred, depending especially on the sources one consults. Still, even conventional matter and dark matter combined might be unable to explain some of the phenomena observed, like the accelerated expansion of the universe that has been witnessed for the first time in different experiments in Kosmicheskie luchi kak istochnik galakticheskogo radioielueniia.

Wilson invented the chamber when working on the condensation of super-saturated water vapor shortly before [ ]. From the s onwards, detectors were optimized for use in connection physice accelerators, while in principle they could have been used with cosmic rays as well.

Wikimedia Italia added it Dec 31, Another technical device that played a decisive role in the early research of cosmic radiation has not been regarded here properly so far: Working with a cloud chamber in a magnetic field, Anderson came across strange tracks of particles that could not phyics been caused by his experimental setup and that resembled those of the electron, but were obviously of positive charge.

Oxford University Press; The asttroparticle between individual people, between people and institutions, as well as people and their respective work fields especially have not been analyzed properly so far. With the increase in energy came an analogous increase in weight: Due to a lack of more specific literature about the different stages of cosmic-ray studies or even astroparticle physics, the following paragraphs will give a brief survey of the disparate parts that form the current state of research on the topic.

Astropargicle, next to teaching, publishing is another indicator of the reproductive character of scientific disciplines [ 94 ].

But balloon flights were not the only means of high altitude research; a number of observatories were erected and existing stations were extended for the special needs of cosmic-ray research.

There were also several observatories in North America and in Asia. Today one would maybe praise their approach as interdisciplinary, yet, it makes it more difficult to classify the first steps that later led to the discovery of cosmic rays, according to disciplines or fields.
