Verfluessigung der Kohle und Herstellung der Sonnentemperatur (German Edition),Used
Delivery time: 8-12 business days (International)
Ehe ich nicht durch anderweitige Versuche widerlegt worden bin, muss ich es als erwiesen betrachten, dass wir es bei meinen Versuchen mit dem fluessigen Zustand des reinen Kohlenstoffs zu tun haben. Gedacht als simples Schlusswort eines Vortrages, entbrennt an dieser Aussage Otto Lummers seinerzeit eine hitzig gefuehrte Diskussion, die auch vor der Diamantindustrie nicht Halt macht, da eine kuenstliche Herstellung von Diamanten einer Revolution der Branche gleich kaeme. Schliesslich sieht sich der Autor gezwungen, das hier vorliegende Werk zu nutzen, um Klarheit ueber seine Forschungen zu schaffen und Stellung zu beziehen. Untermauert wird das Ganze durch eine Zusammenfassung der bis dato bekannten Geschichte des Kohlenstoffs. Qualitativ hochwertiger und bearbeiteter Nachdruck der Originalausgabe von 1914.
