THE FIRST MARTIAN
OUR continued experiments in radio and television may play a much more important part in the eventual realization of successful interplanetary travel than we can possibly conceive of right now. But if we stop a moment to think about it, the possibilities of such closely allied work between radio, television and rocket travel take on vast proportions—one phase of which is vividly portrayed in this short science fiction gem.
Synthetic Platinum
THE American people have never clamored for a true, detailed account of the arrival of the First Martian. Yet the event, unheralded and unprecedented though it was, was one of the most important occurrences in human history. His coming was a distinct shock to the whole world, despite the marvelous advances of science from its birth in 1896 to that date. The inconceivable distance to be traversed, the enormous energy required to transport a heavy machine from planet to planet, and the all-powerful force of gravity, seemed insurmountable objects to even the most broadminded and optimistic thinkers. Feeble attempts were made even in 1931 to leave this speck of the universe and soar to other worlds, but constant failures dulled the ardor of those who wished to connect our world with the others which acknowledge the same central sun. Hope flourished after the almost successful (perhaps indeed successful) attempt of four German scientists to soar from the hidebound earth, who departed in their famous rocket in 1938, bound for the moon. The world is certain that they never returned, unless they landed in some very remote spot, unseen by human eyes; and it cannot be said where they are, whether lost in boundless space, alive or dead on the moon, or perhaps scattered in minute particles in the infinite. Again, five years later, the globular ship of two intrepid Americans vanished from the earth, never to be seen or heard from; and during the period just following the Martian signaling, several others were lost and many more crashed. Although the fatalities far exceeded these probable successes, the hope of interplanetary travel was still uppermost in our minds. We know now, that our failure can be attributed to the unfortunate lack of radioactive elements, and not to the lack of ingenuity or inventiveness. It was only too true, as Professor Billings stated in 1945, that the only type of engine which could possibly transport a heavy machine from our earth to some planet, would have to be the atomic-energy engine, which, with a minimum of fuel and the very necessary radioactive element, could develop an unlimited amount of energy.
He even drew plans of the basic principles of such an engine, estimated the amount of radioactive material needed, and worked out the propulsion of the ship. The theory, which he advanced to the scientific world, was the direct cause of Professor Riehm’s remarkable development of transmutation of elements, for it was found, upon investigation, that at least twenty-five times the amount of actinium existing in the world would be needed to send a ship to the moon. Professor Riehm, realizing that the probability of discovering a rich ore of actinium was too remote to be relied on, decided that transmutation alone was the keynote to this baffling problem.
His first great work was to break down the ordinary platinum of comm
erce to iso-platinum 192! In other words, he made a variety of platinum with a specific gravity of 21.021! It consequently had a lower melting point, a lower specific heat, and higher atomic volume! For a full understanding of this, one must review the past of science, a wonderful stairway of facts and truths, leading to Truth enthroned.
Prout, back in the days of the dawn of science, formulated the theory that elements were aggregates of the hydrogen atom, and hence every atomic weight should come out exactly and without fractions, or very nearly even. His contemporaries, all able men, examined carefully the then existing list of elements, and although a surprising number came out very close to whole numbers, a good many were halfway between.
Stas, a German, then proceeded to redetermine the atomic weights and came to the conclusion that Prout was wrong, for no matter how carefully done, chlorine always came out 35.5, and several others, too, showed an uneven atomic weight, with full allowance for experimental error. This marked the doom of Prout’s hypothesis, and he died in the belief that he had failed to reveal to the world a great truth, because of the bigoted beliefs, and inaccurate work of Stas. As it chanced, both were right. Stas had done his work admirably well, and yet Prout’s Theory was not a mere dream. For early in this century, a series of brilliant spectroscopic experiments proved that many, in fact most, of the elements, were mixtures of bodies, chemically alike, but EACH HAVING A WHOLE NUMBER ATOMIC WEIGHT!
For instance, Aston, the investigator, found that tin was composed of no less than eight isotopes, whose atomic weights are as follow: 116, 117, 118, 119, 120, 121, 122, 124. Each of these iso-elements is chemically identical with all the others; but possessed each of varying specific gravities. It will be noticed that two of the isotopes are actually greater in atomic weight than antimony (121.77), the element following tin. No doubt one or two of the isotopes of antimony (they have not yet been investigated thoroughly) are identical in atomic weight with one or two of tin!
The average of all the isotopic weights of any one element, with due regard to their relative proportions, gives the present value for the atomic weight. For as yet (beyond a very limited number) we have not been able to separate the isotopes of many elements.
We shall now, after this short digression, be able better to understand Professor Riehm’s remarkable experiment whereby he made iso-platinum 192. Let us read from his account of the transmutation:
“——it was found that platinum was composed of the following isotopes: 192, 194, 195, and 198. Isotope 192 has a 48He (helium) proton; 194, a 48He—2H (hydrogen) proton; 195, a 48He—3H proton; and 198, a 49He—2H proton. The problem now resolved itself into this: to remove by a sufficiently powerful agency the excess hydrogen protons of isos 194, 195, and 198, leaving isos 192 and 196.
