ABSTRACT
This chapter discusses author's idyllic life, shattered by a call-up order from the military authorities. It also describes starting of scientific life. At that time physics at Breslau was represented by two men who were friends. They are Lummer and Pringsheim. They had been together at the National Physico-Technical Laboratory in Berlin-Charlottenburg, where they had worked together at the establishment of the laws of radiation. It was the period following Max Planck's announcement of his radiation law from which he derived the sensational result that radiation consists of finite quanta of energy hv, where v is the frequency of the oscillation and h a constant. Everybody felt that if this were true it meant the greatest revolution in physics as in fact it turned out to be, not only in physics, but in the whole domain of science and even beyond it, in all applications of human reason.
