...that has nothing to do with releasing so-called atomic energy. There is no such energy in the sense usually meant. With my currents, using pressures as high as 15,000,000 volts, the highest ever used, I have split atoms?but no energy was released. I confess that before I made this experiment I was in some fear. I said to my assistants. I do not know what will happen. If the conclusions of certain scientists are right, the release of energy from (he splitting of an atom may mean an explosion which would wreck our apparatus and perhaps...

Electroplating is the only practical way of putting on tungsten coats. But the electroplater needs a stable solution of a tungsten salt in water. Most tungsten compounds decompose in water or else are altogether insoluble. Professor Fink's accomplishment was to prevent the tungsten atom of his sodium tungstate molecule from going into another tungsten compound. The tungsten atom, thus kept free from changing relations, could be driven by an electric current and deposited on pieces of brass, copper, zinc, iron or carbon...

...Millikan believes that the Universe is constantly regenerating itself. His chief evidence is the cosmic ray, most penetrating known. The energy which this ray carries, he figures, is just the amount which would be released when four atoms of hydrogen, the primeval element, combined to form one helium atom...

Last week, two days before Dr. Michelson died, Dr. Millikan and Sir James joined in a comparative exposition at California Institute of Technology. Sir James's rebuttal to Dr. Millikan's synthesis argument was that as each proton pops away from the core of an exploding atom it generates a cosmic ray. Dr. Millikan agreed that this reasoning might be correct. Nonetheless, he held tenaciously to his own hypothesis...

...Compounds. Temperature of the sun (12,000° F. on the surface, perhaps millions within) is so great that it was believed that elements could not exist there in molecules or compounds, only as free atoms. Henry Norris Russell (Princeton) reported spectographic discovery of seven solar compounds of hydrogen, four of oxygen, and three of other elements. Sun compounds are not stable as earth's. On earth an oxygen atom holds two hydrogen atoms and makes a molecule. On the sun the oxygen holds only one hydrogen atom, and they are ever ready to sunder...
