Work
Mohr was the leading scientific chemist of his time in Germany, and the inventor of many improvements in analytical methodology. He invented an improved burette which had a tip at the bottom and a clamp (a 'Mohr's clip'), which made it much easier to use than its predecessors, which were more similar to a graduated cylinder. His methods of volumetric analysis were expounded in his Lehrbuch der chemisch-analytischen Titrir-methode (1855) (Instructional Book of Titration Methods in Analytical Chemistry), which won special commendation from Liebig and ran to many editions. His Geschichie der Erde, eine Geologic auf neuer Grundlage (1866), was also widely circulated.
In a paper Über die Natur der Wärme (1837), Mohr gave one of the earliest general statements of the doctrine of the conservation of energy:
besides the 54 known chemical elements there is in the physical world one agent only, and this is called Kraft (energy). It may appear, according to circumstances, as motion, chemical affinity, cohesion, electricity, light and magnetism; and from any one of these forms it can be transformed into any of the others.Read more about this topic: Karl Friedrich Mohr
Famous quotes containing the word work:
“The dominant and most deep-dyed trait of the journalist is his timorousness. Where the novelist fearlessly plunges into the water of self-exposure, the journalist stands trembling on the shore in his beach robe.... The journalist confines himself to the clean, gentlemanly work of exposing the griefs and shames of others.”
—Janet Malcolm (b. 1934)
“We didn’t want any men in our group. They drink their loans, they don’t work their stores. Why should we have to pay for their irresponsibilities?”
—Brachiate Guioth De Espinosa, Colombian storekeeper. As quoted in the New York Times, p. A6 (July 15, 1994)
“At each minute we are crushed by the idea and the feeling of time. And there are only two ways to escape this nightmare, Mto forget it: pleasure and work. Pleasure wears us out. Work fortifies us. Let’s choose.”
—Charles Baudelaire (1821–1867)
