| Zusammenfassung | Just over 200 years ago, in June 1824, William Thomson, who was to become Lord Kelvin, was born. From humble beginnings, he was appointed, in 1846, at the unlikely age of 22, Professor of Natural Philosophy at the University of Glasgow, a position he held for the following 53 years. He went on to become one of the greatest of all classical physicists, making many key advances in the fields of thermodynamics, electromagnetism and precision measurement. Among his many achievements, he, along with Rudolf Clausius and others, became one of the founding fathers of the discipline of thermodynamics. Papers he published in the late 1840s to mid-1850s laid the foundations of primary thermometry (through, for example, positing that heat was not conserved but energy was, and that there was such a thing as ‘absolute temperature’ independent of the physical properties of any specific substance), foundations that practicing thermometrists rely on today, whether they know it or not. Kelvin’s name has long been associated with primary thermometry, certainly before his death, and it is fitting that in the modern international system of measurement units (the SI) the unit of thermodynamic temperature is named ‘the kelvin’ in his honour. |
