Helium for Hydrogen-Inquiries by all authorities soon passed over sabotage (incendiary bullets) as the cause of the disaster. Next discussed was static electricity, harges of which all aircraft accumulate, especially when flying in thunderstorm areas. The fact that the Hindenburg's, ground lines had been down for three minutes before the blaze began, thus presumably drawing off all static charges, opposed this theory...
...asbestos lined smoking room, at the door of which a steward always stood to watch outgoing passengers. But the fire apparently started in the stern, indicating the possibility of a short circuit. Since the ship only contained helium near the passenger's compartment, all the rest being hydrogen, any fire would be impossible to control. The ship had passed through an electrical storm over New York...
...Some of the papers reminded him of dead fish and rotten eggs. When he handed the papers back to their authors, he did so in a new way. None of the papers was marked, but flunkers found theirs in a jar from which came the rotten-egg stench of hydrogen sulphide. The papers of even more hopeless dummies Professor Madigan had permeated with butyric acid, for a smell worse than Limburger cheese. Able students were odoriferously rewarded. The jar from which they drew their papers had been fragrantly scented with attar of roses...
...virus which causes tobacco mosaic disease. Crystallization is a property of nonliving matter but when the virus was applied to the leaf it promptly acquired the ability to reproduce itself-a characteristic of life. The virus is a giant molecule weighing 17,000,000 times as much as a hydrogen atom. Dr. Stanley found the molecule to be spherical, with a diameter of .0000002 cm. When Dr. Langmuir made a monofilm of the virus and then transferred the film to a glass plate where its thickness could be measured, he found that the molecule had flattened out like a pancake...
...allo-pregnanolone), the hormone was extracted from pregnancy urine, one-third of an ounce from 10,000 gallons. After its structure was determined, it was easily synthesized from cholesterol, parent substance of other sex hormones. EAP differs from progesterone, a female hormone, only in having four fewer hydrogen atoms. It was administered to a man who had been impotent all his life. After ten days he became potent, and his "condition of ecstasy" lasted three days...
