Theorien zum Urknall und dessen Erforschung im CERN. Die by Felix Lasthofer

By Felix Lasthofer

Facharbeit (Schule) aus dem Jahr 2016 im Fachbereich Physik - Quantenphysik, be aware: 1, , Sprache: Deutsch, summary: Abstract
Die vorliegende Arbeit befasst sich mit den verschiedenen Theorien zum Ursprung des Universums und den dazu durchgeführten Experimenten am CERN. Dabei haben die Fragen nach der Plausibilität der Theorien, nach heutigen criteria, besonderen Wert. Die Erläuterung der dazu geführten Experimente am CERN unterstützt diese Untersuchung. Der erste Teil bearbeitet konkret die verschiedenen Theorien, deren Beweise und aufgetretene bisher ungelöste Probleme. Der zweite Teil behandelt primär den Aufbau und die Funktion des LHCs am CERN, sowie die Ziele der dortigen Arbeit und deren Erfolge. Anschließend werden die Theorien bewertet und evaluiert. Als primäre Informationsquelle für diese Arbeit wurde die Literatur herangezogen. Diese Literaturrecherche unterstützte ich durch einen Besuch beim CERN, bei dem ich mich mit der Funktionsweise der zugehörigen Experimente vor Ort vertraut machte. Es zeigt sich, dass die Urknall Theorie als bekannteste Theorie, trotz einiger ungelöster Fragen, den Anfang des Universums am besten beschreibt. Sollte es in der Zukunft zu schwerwiegenden Problemen mit der Urknall Theorie kommen, wäre die Schleifen-Quantengravitations-Theorie ein geeigneter Nachfolger, da sie im Vergleich mit den anderen Theorien, am wenigsten Probleme aufweist.

Symmetries in Fundamental Physics (Fundamental Theories of by Kurt Sundermeyer

By Kurt Sundermeyer

Over the process the final century it has develop into transparent that either simple particle physics and relativity theories are according to the inspiration of symmetries. those symmetries turn into appear in that the "laws of nature" are invariant less than spacetime variations and/or gauge modifications. the implications of those symmetries have been analyzed as early as in 1918 via Emmy Noether at the point of motion functionals. Her paintings didn't obtain due popularity for almost part a century, yet can at the present time be understood as a ordinary subject in classical mechanics, electrodynamics and distinctive relativity, Yang-Mills sort quantum box theories, and more often than not relativity. in general, as proven during this monograph, many points of physics could be derived exclusively from symmetry issues. This substantiates the assertion of E.P. Wigner "... if we knew the entire legislation of nature, or the last word legislations of nature, the invariance homes of those legislation wouldn't provide us new information." because of Wigner we now additionally comprehend the results of quantum physics and symmetry concerns: Poincare invariance dictates either the attribute houses of debris (mass, spin, ...) and the wave equations of spin zero, 0.5, 1, ... gadgets. extra, the paintings of C.N. Yang and R. turbines finds the implications of inner symmetries as exemplified within the symmetry team of straightforward particle physics. Given this pivotal function of symmetries it's therefore no longer impressive that present study in primary physics is to a very good measure prompted and encouraged by way of issues of symmetry. The remedy of symmetries during this monograph levels from classical physics to now well-established theories of primary interactions, to the most recent examine on unified theories and quantum gravity.

Foundations of Quantum Physics II (1933-1958): 7 (Niels Bohr by J. Kalckar

By J. Kalckar

quantity 7 is an instantaneous continuation of quantity 6, which documented the start of the complementarity argument and its earliest embellishments. It covers the extension and refinement of the complementarity argument from 1933 until eventually Bohrs' dying in 1962. All Bohr's guides at the topic, including chosen manuscripts and extracts of his correspondence with pals and fellow pioneers equivalent to Werner Heisenberg and Wolfgang Pauli, are included.

Divided into , mostly autonomous elements, the quantity starts off with Bohr's contributions to "Relativistic Quantum Theory". including Léon Rosenfeld, Bohr undertook a radical research of the measuring challenge in quantum electrodynamics and tested the complete accordance among the formalism and the results of idealized concept experiments.

The articles within the moment half, even though additionally limited in scope to the sector of physics, tackle a broader viewers. some of the most notable treatises is Bohr's personal account of his debates with Albert Einstein, over greater than two decades, at the consistency, the completeness and the epistemological results of quantum mechanics.

Volumes 6 and seven of the accumulated Works are in flip relating to the imminent quantity 10 which broadens the scope by way of proposing Bohr's functions of the complementarity argument past the area of physics. even if each one quantity might be learn independently, cautious awareness may be paid to the interrelationships among each one quantity in an effort to get pleasure from the subtlety of Bohr's persisted elaboration and fine-tuning of his complementarity argument.
