Inventions
Joly also invented a photometer for measuring light intensity, a meldometer for measuring the melting points of minerals, a differential steam calorimeter for measuring specific heats and a constant-volume gas thermometer, all of which bear his name, together with one of the first color photographic processes, the Joly Colour process. It was the first successful process for producing color images from a single photographic plate.

Famous quotes containing the word inventions:
“Young children constantly invent new explanations to account for complex processes. And since their inventions change from week to week, furnishing the “correct” explanation is not quite so important as conveying a willingness to discuss the subject. Become an “askable parent.””
—Ruth Formanek (20th century)
“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)
