To this very day, the textbook ”Praktische Physik” (Practical Physics), which originated in Friedrich Kohlrausch’s ”Leitfaden der praktischen Physik” (Guidelines to Practical Physics), is standard reading for physicists and engineers in Germany. This is attributable, above all, to the detailed descriptions provided of the precision measuring methods that form the basis of technical and experimental applications in a wide diversity of fields in physics.

Some of Kohlrausch’s pioneering achievements include conductivity measurements on electrolytes, his work on the determination of basic magnetic and electrical quantities, and the enhancement of the associated measuring technologies. It was under his direction that the ”Physikalisch-Technische Reichsanstalt” (then Imperial Physical Technical Institute in Germany) created numerous standards and calibration standards which were also used internationally outside Germany.
| We would like to extend our gratitude to the German Federal Physical Technical Institute (PTB) for kindly supplying us with photos and information on this subject. ”Meister der Messung” (Masters of Measurement), David Cahan’s book on the ”Physikalisch-Technische Reichsanstalt”, was of great help to us. Our special thanks go to Dr. Jens Simon of the PTB for reading through this manuscript for us. |
