January Science History Tidbits

General

In 1885, the first U.S. patent for a roller coasting structure was issued to La Marcus Thompson of Coney Island, NY. (No. 332,762). Coney Island, at the terminus of New York City's extensive trolley line, was already a popular amusement park in 1884, when Thompson opened a new attraction - the Gravity Pleasure Switchback Railway. For a five-cent ticket, passengers sat sideways in cars that by gravity descended the gentle waves of the 600-foot wooden mini-railway, reaching a top speed of six miles per hour. The enormously popular ride earned back Thompson's original $1,600 investment within three weeks. Within four years, he had built about 50 more across the nation and in Europe. On 22 Dec 1885, he patented the gravity switch-back railway.

Biology

In 1947, Stanford University reported the isolation of the polio virus, after three years of research funded by the National Foundation for Infantile Paralysis. The work was done by Drs Hubert S. Loring and C.E. Schwerdt of the Stanford Dept. of Chemistry. Laboratory tests and photographs showed it to be at least 80% pure, and that it could lead to producing an impurity-free vaccine for use against infantile paralysis. Other vaccines existing at the time had problems with large amounts of impurities. The virus was obtained by purification from ground-up brain and spinal cord of rats infected with the polio virus. Electron microscope photographs showed the virus as a spherical partical about 25 nanometers across.

Earth Science

In 1610, Galileo dated his first letter describing telescopic observations in which he saw the moon's cratered surface using his twenty-powered spyglass. He wrote, “... it is seen that the Moon is most evidently not at all of an even, smooth, and regular surface, as a great many people believe of it and of the other heavenly bodies, but on the contrary it is rough and unequal. In short it is shown to be such that sane reasoning cannot conclude otherwise than that it is full of prominences and cavities similar, but much larger, to the mountains and valleys spread over the Earth's surface.” Galileo went on to describe the phenomena in considerable detail, rehearsing, as it were, the observations and conclusions he was to publish more elaborately a few months later in Sidereus Nuncius.

Physics

In 1919, Professor Ernest Rutherford succeeded in splitting the atom. By bombarding nitrogen atoms with alpha particles emitted by radioactive materials he transmuted the nitrogen atoms into oxygen.

Chemistry

In 1833, Robert Kane, a 24-year-old Irish chemist, published a paper in which he was the first to propose the existence of the -C2H5 ethyl radical (Dublin Journal of Medical and Chemical Sciences, which he founded). His idea was initially "a subject of amusement and ridicule among the chemical circles" of Dublin. A year later, when similar ideas were proposed by Justus Liebig, the authority of that great German chemist gave credibility to the concept, and Kane eventually received the credit for it. By the age of 22, he had already written a book, Elements of Practical Pharmacy, and was a professor of chemistry at Dublin's Apothecaries' Hall. His research spanned inorganic, organic, physical, biological and applied chemistry.
