Tips

history
William Thomson (1824-1907) was made Baron Kelvin of Largs in 1892 — 'Kelvin' from the River Kelvin near Glasgow University, where he taught for 53 years. He formulated the absolute temperature scale that bears his name (开尔文), helped lay the first transatlantic telegraph cable, and famously declared in 1900 that physics was nearly complete — five years before Einstein's annus mirabilis.
usage
开尔文 (Kāi'ěrwén) doubles as the name of the SI temperature unit. Note 0 K (开尔文) has no degree sign by convention — 'kelvin' not 'degrees kelvin'. The pinyin apostrophe Kāi'ěrwén marks the syllable break before .
