...subjects of the lectures are as follows: April 9--Discovery of the Electron; April 11--Ether Wayes, Visible and Invisible; April 13--Atomic and Sub-Atomic Magnitudes; April 16--Light Darts; April 18--Relativity Inside the Atom; April 20--Cosmic Rays...
...theories. He found, using the Einstein equation (M C 2-E), that the most conspicuous band in the cosmic ray spectrum is probably the same band that would be formed by the monochromatic ether wave of the radiant energy which is liberated when hydrogen unites to form an atom of helium. Einstein's figure was reached by calculation: he reasoned that if 4 atoms of hydrogen united to form helium, a definite amount of matter would go off in the form of radiant energy. This energy, appearing in the form of a monochromatic ether wave, would give that ether...
...beta rays (electrons, negatively charged particles) rat-tat-tat-ing against the atoms of elements might conceivably change those elements into new and precious forms. Mercury might yet become gold, as alchemists dreamed. Theoretically the procedure is simple. An atom of mercury contains at its centre, 198 protons (positively charged particles) and 118 electrons. Around that nucleus swirl 80 more electrons. These complete the mercury balance of 198 electrons against 198 protons. An atom of gold contains 197 protons and 118 electrons in its nucleus and 79 more electrons shooting around them. If it becomes possible for the beta particles...
...these words there was an atom of meaning, they implied that Signer Mussolini is meeting, at last, with some success in his ambitious scheme to draw Rumania out of the orbit of her time-honored ally, France. An Italian-Albanian-Bulgarian-Rumanian rapprochement spanning the lower Balkans and linked up with Hungary, thus encircling Italy's enemy Jugoslavia, has long been a favorite pipe dream for correspondents. Lest it crystallize into a rumor, M. Titulescu prepared, last week, to visit Paris for a friendly chat with Foreign Minister Aristide Briand of France...
...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 less comprehensible smithereens...
