Inventions
Jones was a prolific inventor. He was responsible for at least eighteen registered patents, and authored dozens of articles on such subjects as photometry, physical optics, illuminating engineering, colorimetry, photography and motion pictures. One of his wartime inventions was a scope-like observation device called a visibility meter (U.S. Patent No. 1,437,809), which measured a ship’s visibility in an ocean setting (Ackerman 1930).

Famous quotes containing the word inventions:
“By whatever means it is accomplished, the prime business of a play is to arouse the passions of its audience so that by the route of passion may be opened up new relationships between a man and men, and between men and Man. Drama is akin to the other inventions of man in that it ought to help us to know more, and not merely to spend our feelings.”
—Arthur Miller (b. 1915)
“Our inventions are wont to be pretty toys, which distract our attention from serious things. They are but improved means to an unimproved end, an end which it was already but too easy to arrive at; as railroads lead to Boston or New York.”
—Henry David Thoreau (1817–1862)
“Of all the inventions of man I doubt whether any was more easily accomplished than that of a Heaven.”
—G.C. (Georg Christoph)
