Split Quantum. One theory of matter is the quantum theory? that all things, all radiations are built up of quanta, or trifling pulsations of energy. Light is thus considered the effect of many quanta popping after one another. Dr. A. J. Dempter of the University of Chicago told how he had directed the light from a single vibrating atom at a thinly silvered mirror. In theory a single file of quanta battered at the mirror. Part of these reflected away, part passed through, just as would ordinary light. Possibly, thought Dr. Dempter, the quantum, smallest theoretical unit, was split into...

...with understanding, to the address of Dr. W. Heisenberg, young German, on the quantum theory of the structure of the universe. The quantum theory, as originated three decades ago by Dr. Max Planck, denies the existence of matter, as commonly conceived, replacing it with energy in basic units called quanta. As modified by Dr. Heisenberg, quanta depart entirely from such reality as can be apprehended by the senses, becoming terms in pure mathematics. Like the first few people to understand Dr. Albert Einstein, the Heisenberg enthusiasts agreed that the modified quantum theory is of epochal theoretical importance but, to laity...
