...motion is simple-action and reaction. Escaping gases act in one direction, the rocket body in the opposite. The ground is not necessary for the rocket gases to push against in order to propel the rocket. Nor is the air. Such action and reaction can take place in a vacuum, a fact which has driven Professor Goddard on his experiments. His objective is not to see how far he can shoot a rocket but to investigate the physics of the earth's third and outermost blanket...
...third and outer blanket, the Heaviside layer, very little is known, and that only inferentially. Pressure 100 miles up is calculated to be 1/300,000 of the pressure at sea level, practically a vacuum. Highly tenuous though that upper medium is, it is nonetheless dense enough to burn up meteors by its friction. Like the lower atmosphere it carries electrical charges. Proof of that is the great heights from which the curtains of Aurora Borealis, an electrical phenomenon, hang. If Professor Goddard, or anyone else, can learn the exact nature of that high zone it is conceivable that man will...
...trap the heart's action current they would strap two electrodes to the subject's chest, one above the heart's top, the other about six inches lower. From the electrodes ran 60-ft. wires to a "cardiotachometer," which Dr. Boas devised. Vacuum tubes in the cardiotachometer amplified the heart action current which thereupon operated a counting device and a recording pen. The long wires enabled the subject to practice most of his usual occupations. The counter recorded the total number of his heart beats over any desired period (most importantly for study, during sleep...
