Coil Quotes (4 quotes)

[In high school,] I continued interest in experiments in physics related to astronomy and spectroscopy. I remember building various gadgets involved with the spectrograph in country houses that we rented in the summer, well before going to college. About 1923 our school radio club erected a giant-antenna and communicated with Australia by voice, which was I think early for radio amateurs. I had an early interest in radio. I remember back in summer camp hearing radio stations with an old crystal detector with coils I had wound when I was only nine or ten. Thus, I had an interest in radio at the beginning of radio astronomy in the United States [1933].

Question: What is the reason that the hammers which strike the strings of a pianoforte are made not to strike the middle of the strings? Why are the bass strings loaded with coils of wire?
Answer: Because the tint of the clang would be bad. Because to jockey them heavily.
Genuine student answer* to an Acoustics, Light and Heat paper (1880), Science and Art Department, South Kensington, London, collected by Prof. Oliver Lodge. Quoted in Henry B. Wheatley, Literary Blunders (1893), 176, Question 3. (*From a collection in which Answers are not given verbatim et literatim, and some instances may combine several students' blunders.)

It was shortly after midday on December 12, 1901, [in a hut on the cliffs at St. John’s, Newfoundland] that I placed a single earphone to my ear and started listening. The receiver on the table before me was very crude—a few coils and condensers and a coherer—no valves [vacuum tubes], no amplifiers, not even a crystal. I was at last on the point of putting the correctness of all my beliefs to test. … [The] answer came at 12:30. … Suddenly, about half past twelve there sounded the sharp click of the “tapper” … Unmistakably, the three sharp clicks corresponding to three dots sounded in my ear. “Can you hear anything, Mr. Kemp?” I asked, handing the telephone to my assistant. Kemp heard the same thing as I. … I knew then that I had been absolutely right in my calculations. The electric waves which were being sent out from Poldhu [Cornwall, England] had travelled the Atlantic, serenely ignoring the curvature of the earth which so many doubters considered a fatal obstacle. … I knew that the day on which I should be able to send full messages without wires or cables across the Atlantic was not far distant.
As quoted in Degna Marconi, My Father, Marconi (2000), 93.

We wish to put forward a radically different structure for the salt of deoxyribose nucleic acid. This structure has two helical chains each coiled round the same axis (see diagram).
[Co-author with Francis Crick]
From James Watson and Francis Crick, 'Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid', Nature (25 Apr 1953), 171, No. 4356, 737.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
