Eine Erweiterung des Differenzen-Verfahrens zur Berechnung von kugelsymmetrischen Temperaturfeldern
(1947)
Mit dem Differenzenverfahren können in einfacher Weise beliebige Anheiz- und Abkühlungsvorgänge, soweit sie kugelsymmetrisch verlaufen, behandelt werden. Sowohl der Fall, daß eine Kugel von einem Medium konstanter Außentemperatur umgeben wird, wie auch der Fall, daß die Temperatur ohne Störung durch Konvektion in der Umgebung der geheizten Kugel sich einstellt, wird erörtert und führt auf leicht durchführbare Rechnungen und Konstruktionen. Zum Schluß wird gezeigt, wie sich aus den angegebenen Rekursionsformeln die analytischen Gesetzmäßigkeiten der stationären Temperaturverteilung leicht elementar ableiten lassen.
Im ersten Teil werden kurz die entscheidenden Schwierigkeiten der beiden bekanntesten Versuche zur Erklärung der Eiszeiten, und zwar der Pol-bzw. Kontinentalver-schiebungen (Epeirophorese) und der sog. astronomischen Theorie (Schwankungen der Schiefe der Ekliptik und der Erdbahnelemente) aufgezeigt. - Im zweiten Teil wird wahrscheinlich gemacht, daß eine schon 1921 vorgetragene Hypothese von Shapley, nach der die Sonne in der diluvialen Eiszeit eine von kosmischen Dunkelwolken verursachte schwache Veränderlichkeit ihrer Strahlung zeigte, nach neueren, in erster Linie astrophysikalischen Forschungsergebnissen eine brauchbare Erklärung zu liefern imstande ist, aus folgenden drei Gründen:
1. In allen dichteren kosmischen Dunkelwolken findet man unregelmäßige veränderliche Sterne eines ganz besonderen Typus; im Gegensatz zu fast allen übrigen Typen veränderlicher Sterne handelt es sich bei diesen Sternen um Zwergsterne, wie die Sonne oder noch schwächer.
2. Unser Sonnensystem befindet sich gegenwärtig innerhalb dunkler kosmischer Materie, und es ist höchstwahrscheinlich, daß es in naher Vergangenheit auch dichtere Teile von solchen Dunkelwolken durchquert hat.
3. Die Form der Dunkelwolken, ihre armförmigen, zirrus-oder zirrostratusähnlichen Anordnungen und Verästelungen lassen eine zwanglose Erklärung der mehrfachen Wiederholung der Eiszeiten zu; es wird hier also nicht nur die Eiszeit, sondern aus der gleichen Hauptursache auch deren Gliederung erklärt, was sonst nicht gelungen zu sein scheint.
Die Mitwirkung anderer, in erster Linie astronomischer und geographischer Faktoren, letztere insbesondere in der älteren Erdgeschichte, ist durchaus möglich.
Nach neueren Messungen besitzt das Auge eine definierte Empfindlichkeit noch bis etwa 1.0 μ. Es wird hier eine Formel mitgeteilt, die die Messungsresultate befriedigend darstellt. Ihre Auslegung deutet darauf hin, daß der Abfall der Augenempfindlichkeit in diesem "ultraroten" Bereich gerade hinreichend rasch erfolgt, daß keine Dunkelreaktion im Auge den Sehakt stört.
Die Vorstellungen des Wilsonschen Halbleitermodells werden quantitativ durchgeführt und die Abhängigkeit der Fermischen Grenzenergie von Temperatur, Konzentration und Art der Störstellen berechnet. Es ergibt sich, daß die Grenzenergie das elektrische Verhalten des Halbleiters entscheidet. Bisher ungeklärte experimentelle Ergebnisse werden gedeutet.
An Hand neuerer paläoklimatologischer Forschungsergebnisse wird nachgewiesen, daß sowohl die Polwanderungstheorie als auch die astronomische Theorie von Milankovitch in bezug auf die Verhältnisse während des Känozoikums und namentlich während des Alluviums versagen. Es wird weiterhin ausgeführt, daß die Nebelveränderlichkeit nicht etwa durch rein optische Bedeckungseffekte, sondern durch die Bildung einer dichten, den Stern umgebenden Hülle, welche den Energietransport in der Sternatmosphäre stört, hervorgerufen wird. Die kleineren Schwankungen innerhalb der Eiszeiten (Interstadialzeiten) und die kurzdauernden Schwankungen des Alluvialklimas können durch die faserige (Filament-) Struktur der Dunkelwolken erklärt werden.

Der Einfluß von Elektrodenpolarisation auf die Bestimmung der elektrischen Konstanten leitfähiger Substanzen wird untersucht; es wird gezeigt, daß der durch Polarisation bedingte Effekt auf die Kapazität um mehrere Zehnerpotenzen größer ist als der auf die Wirkwiderstandskomponente. Die Bestimmung der Dielektrizitätskonstante stark leitfähiger Materialien bei Niederfrequenz wird dadurch sehr erschwert. Die verschiedenen Möglichkeiten, Polarisationseinflüsse herabzusetzen, werden diskutiert und es wird gezeigt, daß einzig eine Messung mit verschiedenem Elektrodenabstand einwandfreie Ergebnisse gewährleistet, wenn Polarisation merklich auftritt. Eine bei biologischen Arbeiten öfter angewandte Methodik geht von der Voraussetzung aus, daß beim Austausch biologischen Materials gegen eine Salzlösung gleicher Beschaffenheit, wie sie intrazellular im biologischen Material vorliegt und in Kontakt mit den Elektroden steht, die Polarisationsimpedanz keiner Änderung unterliegt. Die Analyse eigener experimenteller Untersuchungen, über die berichtet wird, zeigt, daß diese Annahme nur berechtigt ist, wenn das biologische Material in so hinreichend großem Abstand von den Elektroden angeordnet wird, daß keine Schattenwirkung auftreten kann. In allen anderen Fällen ist sie falsch, und Arbeiten, die dem nicht Rechnung tragen, sind kritisch zu bewerten.
