    Footnote
    Während sich die Beiträge zur Urtheorie an Spezialisten wenden, finden sich zu anderen Arbeitsgebieten von Weizsäckers eher allgemeinverständliche Darstellungen: Astro- und Kernphysik mit den thermonuklearen Prozessen in Sternen und der Entstehung der Planetensysteme sowie die Philosophie der Naturwissenschaft und der Zeit - alles in der für solche Festschriften typischen bunten Mischung. Hervorgehoben sei die Darstellung des Hamburger Friedensforschers Götz Neuneck zur deutschen Atomforschung während des Zweiten Weltkriegs und zu den nachfolgenden Bemühungen internationaler Wissenschaftler, die Institution des Kriegs nach dem Bau der Atombombe abzuschaffen. In beiden hat von Weizsäcker eine herausragende Rolle gespielt. Ein wichtiges Thema des Buchs sind die Grundlagen der Quantentheorie. Mit der Charakterisierung von Objekten durch Information ist die Urtheorie eine radikale Weiterführung der »Kopenhagener Deutung«, jener orthodoxen, aber von vielen Physikern nur mangels einer überzeugenden Alternative akzeptierten Interpretation der Quantentheorie. Ein seit deren Anfängen andauernder Streit geht darum, ob die Wellenfunktion, die Wahrscheinlichkeiten für Messergebnisse vorhersagt, gemäß der Kopenhagener Deutung das mögliche Wissen eines Beobachters darstellt oder eine davon unabhängige Realität beschreibt. Wie lebendig diese Debatte ist, machen mehrere Beiträge in diesem Buch deutlich. Hans Primas und Harald Atmanspacher lösen den Widerspruch nach dem Muster des Teilchen-Welle-Dualismus auf Beide Positionen beruhen auf unterschiedlichen Auffassungen der Wirklichkeit, die beide für eine Beschreibung der Natur je nach der zu Grunde liegenden Fragestellung notwendig seien. Claus Kiefer erläutert das Phänomen der »Dekohärenz«, wonach der quantenmechanische Messprozess in neuem Licht erscheine, wenn auch die Kopplung des Messgeräts an seine Umgebung berücksichtigt werde, denn unrealistische Überlagerungszustände im Messprozess wie die berühmte sowohl tote als auch lebendige »Schrödinger'sche Katze« seien bereits durch die Quantenmechanik selbst ausgeschlossen. Spätestens wenn der Kosmos als Ganzes betrachtet werde, komme die Kopenhagener Deutung an ihr Ende, denn hier gebe es keinen Beobachter mehr, für den die quantentheoretischen Möglichkeiten zu Fakten werden könnten.
