Essay aus dem Jahr 2008 im Fachbereich Physik - Sonstiges, be aware: "-", , 25 Quellen im Literaturverzeichnis, Sprache: Deutsch, summary: Albert Einstein zufolge ist die Zeit relativ. Das bedeutet, dass zwei unterschiedliche bewegte Beobachter eine Zeitspanne, die zwischen denselben Ereignissen liegt, als verschieden lang empfinden können. Bei der Zeittheorie sind die Gedankenmodelle der speziellen und der allgemeinen Relativitätstheorie zu unterscheiden. Das eben genannte Zeit-Empfindungsmodell ist der speziellen Relativitätstheorie zuzuordnen.
Die allgemeine Relativitätstheorie handelt von beschleunigten Systemen und definiert die Gravitation als eine Krümmung von Raum und Zeit. Die Krümmung resultiert aus der Existenz von Massen.1 Kurt Gödel erfand die Weltformel für Zeitreisen auf der Grundlage von Einsteins Relativitätstheorie. Stephen Hawking schwankt zwischen der Machbarkeit von Zeitreisen und deren Verneinung. Roy Kerr versucht die Existenz von Schwarzen Löchern zu beweisen, während Kip Thorne darüber reflektiert, wie ein Wurmloch beschaffen sein müsse, damit guy durch die Zeit reisen kann. Aktuelle Visionen von dem Bau einer Zeitmaschine stellen die Physiker Amos Ori und Ronald L. Mallett vor.2 Auf der Grundlage der Zeitreisen-Philosophie ergibt sich die Frage, u. a. auch resultierend aus der Forschung mit dem Teilchenbeschleuniger LHC (Large Hadron Collider) am CERN (Conseil Européen pour l. a. Recherche Nucléaire)3 in der Schweiz, inwieweit Zeitreisen realisierbar sind und welche neurologischen und das menschliche Bewusstsein betreffende Faktoren im Rahmen der Kausalitätsproblematik proper sind. Daraus resultierend lohnt es sich zu überlegen, inwieweit die Zeitreisenforschung ein ewiges (virtuelles) Leben ermöglichen könnte.

used to be fur eine schone Idee! Siegfried Hess erklart allen Menschen ab 10 Jahren, was once die Welt im Innersten zusammenhalt und was once die Physik damit zu tun hat. Die Grundlagen dafur beginnen mit der Mechanik. Wussten Sie, dass es eine himmlische, eine irdische und eine hollische Mechanik gibt? Die himmlische Mechanik erklart die Bewegung der Erde um die Sonne und die des Mondes um die Erde. Die irdische beschaftigt sich mit der Mechanik auf der Erde - u. a. mit Radern, Hebeln, dem Fliegen oder Reibung und Bewegungen, und die hollische Mechanik schlie?lich behandelt den Flug und die Wirkung von Kanonenkugeln und anderen Geschossen.

FORSCHER UND IHRE ENTDECKUNGEN: VON HEINRICH HERTZ BIS ZU MAX PLANCK
used to be die klassische Mechanik nicht erklaren kann - die Physik der Atome und Molekule und ihre Wechselwirkung mit Licht -, das erklart die Quantenmechanik. Hess stellt - wie auch schon zuvor - Forscher und Entdecker vor und bringt den Lesern so das Gebiet der Quantenmechanik nahe.
Wer eine Auflockerung dazwischen braucht, der kann sich mit dem >Teekesselspiel< vergnugen oder die Fantasiegeschichte >Was ware, wenn an der Planck-Konstanten gedreht wird?< lesen. Mitwirkende: Albert Einstein, Max Planck und Max von Laue und viele andere ? frei erfunden von Siegfried Hess.
