Nach einleitenden Betrachtungen über das heute beherrschte Frequenz­ Leistungs-Gebiet elektromagnetischer Schwingungsenergie wird ein neues Verstärkerprinzip beschrieben, das im Mikrowellengebiet eine Verringerung des Eigenrauschens auf weniger als den zehnten Teil des Rauschens der bis jetzt bekannten Verstärker ergibt und die Handhabung einzelner Energie­ quanten in Aussicht stellt. Gewinn-und Bandbreiteeigenschaften der beiden technischen Varianten des Molekularverstärkers - Molekularverstärker mit Resonanzkreisen und Traveling-Wave Molekularverstärker - werden theo­ retisch untersucht und eine eingehende Beschreibung des Aufbaues und der elektrischen Eigenschaften der wichtigsten bisher durchgeführten Verstärker wird gegeben. ’ Summary After certain introductory considerations on the frequency power range of electromagnetic oscillation energy in the present state of technique, the author describes a new amplifier principle resulting in areduction of inherent amplifier noise in the microwave range on less than a tenth of noise of amplifiers known today; this principle also seems to offer the possibility of handling single energy quants. The author then analyzes theoretically the gain and bandwidth characteristics of the two technical variants of the molecular amplifier - i. e. , molecular amplifier with resonant circuits and traveling-wave molecular amplifier -, and describes the struc­ tural and electrical characteristics of some amplifier types built until now.

    While the great scientists of the past recognized a need for a multidisciplinary approach, today’s schools often treat math and science as subjects separate from the rest. This not only creates a disinterest among students, but also a potential learning gap once students reach college and then graduate into the workforce.

    University of Texas at Austin My friendship with Freeman Dyson goes back over a half century. My first contact with him goes back to the late 1950s, when I was at the Institute for Advanced Study, and then evolved when I was a consultant at General Atomics in La Jolla, California. Freeman was then trying to design a space ship — the Orion — which would be propelled by atomic bo...
