Langley invented the bolometer, an instrument for measuring infrared radiation. The bolometer has enabled scientists to detect a change of temperature of less than 1/100,000 of a degree Celsius. It laid the foundation for the measurements of the amount of solar energy on the Earth. His 1881 paper, The Bolometer and Radiant Energy, became a scientific classic. He made one of the first attempts to measure the surface temperature of the Moon, and his measurement of interference of the infrared radiation by carbon dioxide in Earth's atmosphere was used by Svante Arrhenius in 1896 to make the first calculation of how climate would change from a future doubling of carbon dioxide levels.

Famous quotes containing the word work:
“I watched a small man with thick calluses on both hands work fifteen and sixteen hours a day. I saw him once literally bleed from the bottoms of his feet, a man who came here uneducated, alone, unable to speak the language, who taught me all I needed to know about faith and hard work by the simple eloquence of his example.”
—Mario Cuomo (b. 1932)
“only an aching heart
Conceives a changeless work of art.”
—William Butler Yeats (1865–1939)
