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:
“Enough if the work has seemed,
So did she your strength renew,
A dream that a lion had dreamed
Till the wilderness cried aloud.”
—William Butler Yeats (1865–1939)
“One way or another we all work for our vice.”
—Ben Maddow (1909–1992)
“There is no mystery in a looking glass until someone looks into it. Then, though it remains the same glass, it presents a different face to each man who holds it in front of him. The same is true of a work of art. It has no proper existence as art until someone is reflected in it—and no two will ever be reflected in the same way. However much we all see in common in such a work, at the center we behold a fragment of our own soul, and the greater the art the greater the fragment.”
—Harold C. Goddard (1878–1950)
